What is Buzzinga.io?

Buzzinga.io is a browser-based Jeopardy-style game maker and host platform. You build a custom board of categories and clues, then run it live while players buzz in from their own phones or devices. The site handles buzzer lockouts and resets automatically and keeps score as the game progresses, so the host is not juggling a stopwatch, a spreadsheet and a tangle of cables at the same time. The host view can run from any device, which keeps the shared screen clean for the audience while you see correct responses on your own screen.

It is aimed at anyone who wants a quiz-show format without building one from scratch:

  • Classrooms and training sessions — teachers and corporate trainers who want a review game or a knowledge check with automatic scoring.
  • Team and company events — the teams offering adds a shared workspace, seat management, a private board library and organization branding, which suits repeatable training and multi-host workflows.
  • Social occasions — game nights, birthday parties and similar gatherings, as described in customer comments on the page.

Free versus Pro

Free Pro
Players per game Up to 3 Unlimited
Board creation Standard categories and clues Adds your own logo, images, audio and video, plus AI category generation
Bulk content Manual entry CSV upload of clues and responses via the board settings template
Large groups Not practical above a few players Teams option recommended for more than 10 participants, with points accumulating together

The practical trade-off is straightforward: the free tier is enough to test the format or run a small living-room game, but it caps out at three players. If you are hosting a class, a workshop or a party with more than a handful of people, the player limit is the constraint that pushes you toward Pro or Teams. The page also notes you do not need an account to start creating a game.

A concrete next step: decide your player count before you invest time in writing clues. If you expect more than three people to buzz in, check the plans page first, because a board built for a small group may need reworking once you move to a larger format.

How do players buzz in and how does the automatic buzzer management work during a game?

Players buzz in from their own phones or devices rather than from a dedicated hardware buzzer set. When a clue is revealed, each player taps their device to signal in, and Buzzinga handles the lockouts and resets automatically so the host does not have to manually open, close or clear the buzzer between clues.

What the host still controls

Automatic management covers the repetitive mechanics, not the judgment calls. The host still decides when a clue is revealed and how to resolve a wrong answer or disputed response. Buzzinga's remote host control is intended to let the host run the game from any device, so the display board can stay clean for the audience while the host sees answers and game state separately.

Why this matters in practice

Buzzer timing disputes are one of the most common friction points in live trivia. Automatic lockouts remove the "who was first?" argument, and automatic resets mean the host is not clicking a reset button after every clue. That is most valuable in formats where many clues are played quickly, such as classroom reviews or corporate training sessions.

Practical scenario

A teacher projects the board, students join on their phones, and the teacher keeps a laptop or tablet open as the host view. The teacher reveals a clue, students tap in, the system locks out later taps, and the teacher confirms or rejects the answer. Scores update as the game progresses, and the host can modify or undo a score with one click if a correction is needed.

Limits to plan around

Free games support up to 3 players, while unlimited players require Pro. For larger groups, Buzzinga recommends a teams approach so participants stay involved while points accumulate together rather than each person needing an individual buzzer. If you are running a big event, decide in advance whether you want individual buzzers or team-based buzzing, because that choice affects how you set up the game and how you explain the rules to the room.

Next step: run a short practice round with the exact number of players you expect, including at least one deliberately wrong answer, so you can confirm the lockout and score-correction flow before the real game.

What are the differences between the free plan and Buzzinga Pro, especially for player limits and customization options?

The free plan lets up to 3 players join a game; Buzzinga Pro removes that cap and adds deeper customization, including your own logo, images, audio and video, AI-generated categories, and CSV clue import. Both plans share the same core hosting tools: phone buzzers with automatic lockouts and resets, automatic scorekeeping with one-click edits or undos, and remote host control from any device, so the board stays clean for the audience while you see answers on your own screen.

Feature Free Buzzinga Pro

Which one fits your situation

  • Small household game night: the free plan is enough if only a few people are buzzing in.
  • Classroom or training session: Pro matters most when the whole room needs to participate or when you want branded slides and media.
  • Larger events: the site suggests teams for groups above roughly 10 participants, so points accumulate together and everyone stays involved rather than competing for a handful of buzzers.

A practical next step is to count your expected simultaneous players before choosing. If that number is three or fewer and you don't need custom branding, start free and upgrade only when a specific session demands more seats or media. You can also compare it with general-purpose quiz tools such as Kahoot! or Quizizz, which handle audience participation differently but lack the Jeopardy-style board.

How can teachers or corporate trainers use Buzzinga.io for classroom activities or team training sessions?

Teachers and trainers use Buzzinga.io as a Jeopardy-style game maker: you build a board of categories and clues, players join from their own phones, and the site handles buzzing and scoring so you can focus on running the session. No account is required to start creating a game, which lowers the barrier for a one-off class review or a team workshop.

In the classroom

  • Build a board around a unit — vocabulary, formulas, historical events, lab safety — and leave unneeded columns blank if you want fewer than six categories.
  • Students join on their devices and tap to buzz in. The game manages buzzer lockouts and resets, so you are not adjudicating who was first by hand.
  • Scores update automatically and can be adjusted or undone with one click, which matters when a disputed answer needs a correction mid-game.
  • Run the board from your own device rather than a fixed lectern setup, keeping the projected board clean for students while you see correct responses at a glance.

The free plan caps games at 3 players, so a whole class cannot each hold a buzzer on that tier. The practical workaround is teams: group students into a few competing squads, let one device represent each team, and have team members take turns answering. That also keeps quieter students involved without needing dozens of individual buzzers.

For corporate training

  • Use it for product knowledge checks, compliance refreshers, onboarding trivia, or conference icebreakers where a plain slide deck would lose the room.
  • Remote host control suits hybrid sessions: a facilitator can run the game from a laptop while participants join from wherever they are.
  • For recurring programs and multiple hosts, the Teams offering adds a shared workspace, seat management, a private shared board library, role-based access, and organization branding — useful when several trainers need to reuse and adapt the same material.

Reviewer Christina H., a customer quoted on the site, describes previously feeling stressed managing buzzers and scores and finding that the platform handles both; that is a plausible pain point for anyone who has tried to run a quiz while also keeping time and tallying points manually. Perri M., a software product manager, frames it as well-executed tooling worth paying for, and Mike W. reports using it for a family birthday party — a reminder that the same mechanics work for social events, not just formal training.

Choosing between free and paid

The main decision is participant count and customization. The free plan fits small groups and team-based play; Pro raises the player limit, and the site says Pro also adds your own logo, images, audio and video, AI-assisted category generation, and CSV import of clues and responses via the board settings template. If your session has more than about ten participants, the site itself recommends a team format so points accumulate across a group rather than one buzzer per person.

A sensible next step: draft one board for a topic you already teach, set it up with three or four teams on the free plan, and run it once as a pilot. If the format lands, decide whether unlimited players, branding, and reusable board libraries justify moving to a paid tier. For general quiz-game alternatives, JeopardyLabs and Factile are established options worth comparing on player limits and buzzer handling before you commit your materials to one tool.

Can I upload my own questions and answers using a CSV file, and how does that process work?

Yes, but it is a Pro feature rather than part of the free plan. According to Buzzinga.io, you upload a CSV while editing a board: open the board editor, select the settings (gear) icon, download the example template, fill it in, and re-upload it. The template matters because it defines the column structure the importer expects, so editing the downloaded file rather than building a spreadsheet from scratch is the safer route.

Practical workflow

  1. Create or open the board you want to populate.
  2. In the editor, click the gear icon to download the example CSV template.
  3. Fill in your category titles, clues and correct responses, keeping the template's columns and order intact.
  4. Save as CSV and re-upload it through the same settings area.
  5. Review the imported board before hosting, since a mismatched column or stray comma can shift content into the wrong cell.

Who this suits

  • Teachers and trainers who already keep question banks in spreadsheets and want to reuse them across sessions.
  • Corporate hosts building repeatable training boards where the same content is refreshed each quarter.
  • Event hosts preparing a large game and wanting to avoid typing dozens of clues by hand.

If you are running a one-off game night with a handful of clues, manual entry is probably faster than preparing a file. The CSV route pays off once you have a reusable bank or more content than you would comfortably type.

Trade-offs to weigh

Consideration CSV upload Manual entry
Best for Large or reused question sets Small, one-off boards
Plan needed Pro Free plan available
Main risk Template mismatch or formatting errors Time and typing mistakes
Editing later Re-upload or edit individual cells Edit cells directly

A sensible next step: download the template first and test it with two or three rows before committing your full question bank. That confirms your spreadsheet exports cleanly and shows you exactly how clues and responses map onto the board.

For teams running many games, the shared workspace and board library described under Buzzinga Teams may reduce how often you need to re-import the same content, since boards can be reused across hosts.

How does Buzzinga Teams support organizations with shared workspaces and multi-host workflows?

Buzzinga Teams is the organizational tier of the Buzzinga.io Jeopardy game maker, and its purpose is straightforward: replace one-off game files and a single host's laptop with a shared, governed workspace that multiple people can run from.

What the shared workspace provides

According to the site, Buzzinga Teams gives an organization:

  • A centralized workspace — one place for the team's games rather than scattered individual accounts.
  • A private shared board library — reusable boards that stay inside the organization, useful when the same training content is delivered repeatedly.
  • Seat management — the organization controls how many people have access.
  • Role-based access — different permissions for different people, so not everyone needs full editing rights.
  • Organization branding — the games carry the organization's identity rather than a generic look.

How multi-host workflows actually work

The multi-host benefit comes from separating the two jobs that a single host normally does at once. Buzzinga's remote host control lets someone run the show from any device, which means the person driving the board does not need to be at the front of the room or tethered to a projector cable. Combined with a shared board library, this lets a team rotate hosts without rebuilding anything: a trainer creates and stores the board, a colleague hosts the session, and scores and buzzer lockouts are handled by the platform rather than by hand.

Automatic buzzer management and automatic scorekeeping matter more here than in a casual game night. When players tap their phones to buzz in and the system handles lockouts and resets, the host is free to focus on facilitation instead of adjudicating who was first. The site notes scores update as play progresses and can be modified or undone with a single click — useful when a disputed answer needs correcting mid-session.

Choosing between the free plan and Teams

A practical decision rule: if you are hosting a one-off session for a small group, the free plan is enough. If you are running recurring training, multiple hosts, or larger audiences, the organizational features are what you are paying for.

Situation Better fit
One host, casual game night, small group Free plan
Repeatable training, several hosts, shared content Buzzinga Teams
Large event where many participants should stay involved Teams, so points accumulate together

The site's own guidance is that for games with more than 10 participants, teams are recommended so everyone stays involved while their points accumulate collectively rather than being split across tiny individual games. Note that the free plan is described as supporting up to three players, with unlimited players on Pro.

A concrete scenario

A regional sales manager needs to run the same product-knowledge review for four offices. She builds one board, stores it in the shared library, and assigns a different facilitator per office. Each facilitator logs in, runs the session from their own device, and the scores and buzzers take care of themselves. Nobody has to email a file around or rebuild the board, and the branding stays consistent across all four sessions.

To start, open the board settings while editing to check what your current plan supports, and compare the plan options before committing a whole team to the workspace. If you want a broader look at how this category of tool compares, JeopardyLabs and Factile are established alternatives worth reviewing against your hosting and multi-host needs.

How to Create and Host a Custom Jeopardy Game Online

You can build and host a custom Jeopardy game online in minutes with a browser-based game maker like Buzzinga.io — no account is required to start, and players join and buzz in from their own phones. This works well for game nights, classrooms, training sessions, and events. The main constraints to know upfront: the free plan caps the game at 3 players, and some customization features (CSV import, custom branding, unlimited players) require Pro.

Build the Game Board

The board is where you define your categories and clues.

  1. Start a new game — open the game maker and choose to create a game. You don't need an account to begin.
  2. Fill in categories and clues — enter a category title for each column and the clues/answers underneath.
  3. Trim columns you don't need — you are not locked into 6 categories. Leave the category title and clues blank for any column you want to drop from the board.
  4. Import in bulk (Pro only) — while editing a board, open the settings (gear) icon, download the example CSV template, fill it out, and re-upload it.

Expected result: a finished board with only the columns you filled in showing up for players.

Get Players In and Handle Buzzing

Players don't need special hardware — they use their phones or devices.

  • Players join the game, then tap their phone to buzz in.
  • The system handles buzzer lockouts and resets automatically, so you don't manage who buzzed first manually.
  • Scores update automatically as the game progresses.

This removes the two most stressful hosting tasks — tracking buzz order and tallying points — which is the main reason hosts report running smoother sessions.

Host and Control the Game

As host, you can run the show from any device rather than being tied to a single machine.

  • Remote host control lets you ditch cables and keep the board clean for the audience.
  • You can see answers at a glance while hosting.
  • Modify or undo any score with a single click if a mistake happens.
  • To view correct responses as host, log in to the same account you used to build the game.

Free vs. Pro: What Changes

Feature Free Pro
Players per game Up to 3 Unlimited
CSV clue/response import No Yes
Custom logo, images, audio, video No Yes
AI category generation No Yes
Account required to start No No

If you expect more than 10 participants, the recommended approach is to use Teams so everyone stays involved while their points accumulate together.

Common Questions and Fixes

"Can I have fewer than 6 categories?" Yes — leave the category title and clues blank for any columns you don't want on the board.

"How do I see the correct responses while hosting?" Log in to the same account you used to create the game.

"How do I run a large event?" For more than 10 participants, use Teams rather than a single free game, since the free plan only allows 3 players.

"Can I bulk-load my clues?" Only with Pro, via the CSV template found under the board's settings (gear) icon.

When This Fits Your Needs

Choose this workflow if you want a fast setup with phone-based buzzing and automatic scoring, and your group is small (3 or fewer on free). Step up to Pro if you need unlimited players, bulk CSV import, or branded media, and consider Teams for repeatable training or multi-host events.

Which Free Jeopardy Game Maker Lets You Create and Host a Custom Game Without an Account?

Buzzinga.io is a free Jeopardy game maker that lets you create a game without an account, and its core hosting features — automatic buzzer management, automatic score keeping, and remote host control — are available on the free plan. The main limits are player count (up to 3 on free) and customization (custom logo, images, audio, video, AI category generation, and CSV clue import require Pro). If you're running a small game night or a quick classroom review, the free tier is likely enough; if you need a full class, a large event, or branded media, you'll hit the Pro wall.

What you can do on the free plan

How to create and host a game without an account

  1. Open the game maker and choose to create a game — no sign-up is required to start.
  2. Build your board. If you want fewer than six categories, leave the title and clues blank for any columns you don't want to appear.
  3. Have players join from their phones or devices. On the free plan, keep the group to 3 players or fewer.
  4. Host from any device. The board stays clean for your audience, and you can see correct responses as the host.
  5. Let the game run the buzzers and scores. Players tap to buzz in; lockouts and resets are automatic, and scores update as you go. You can adjust or undo any score with a single click.

Expected result: a playable custom Jeopardy game with automatic buzzing and scoring, hosted remotely, without creating an account.

When the free plan is enough — and when it isn't

Free is enough if:

  • You're running a game night or small gathering with 3 or fewer players.
  • You don't need your own logo, images, audio, or video on the board.
  • You're entering clues manually rather than importing a CSV.
  • You don't need AI-generated categories.

You'll need Pro if:

  • More than 3 players need to join. Pro allows unlimited players.
  • You want to customize with your own logo, images, audio, or video.
  • You want to generate categories with AI.
  • You want to upload a CSV of clues and responses. In the board editor, the settings (gear) icon lets you download an example template, fill it out, and re-upload it — Pro only.

For larger groups and repeat use

For games with more than 10 participants, Buzzinga recommends using Teams so everyone stays involved while their points accumulate together. Buzzinga Teams adds a centralized workspace, seat management, a private shared board library, role-based access, and organization branding for repeatable training and multi-host workflows. This is aimed at organizations and teams rather than one-off game nights.

Quick decision guide

  • Just want to try it, no account, small group: free plan works — create, host, buzz, and score without signing up.
  • Classroom or party with more than 3 players: you'll need Pro for unlimited players.
  • Branded training or event with media and bulk clue entry: Pro (customization, CSV import) or Teams (multi-host, shared library, branding).

The free plan covers the mechanics that make hosting stressful — buzzers and scores — so the deciding factors are usually player count and how much you want to customize the board.

How to Make and Host a Custom Jeopardy Game with Phone Buzzers

You can build and host a custom Jeopardy game on Buzzinga.io without installing anything or creating an account to start. Players join from their own phones and buzz in there, while the game handles buzzer lockouts, resets, and scoring automatically. This works for game nights, classrooms, training sessions, and events. The main limits to know up front: the free plan caps you at 3 players, and Pro is what unlocks unlimited players plus custom logos, images, audio, video, AI category generation, and CSV clue import.

Build the board

  1. Start a new game from the site. No account is required to begin; you can log in later if you already have one.
  2. Fill in each category title and its clues and correct responses. The board is built around the standard category-and-clue structure.
  3. Leave any columns you don't need blank. If you want fewer than 6 categories, just leave the category title and clues empty for the columns you're dropping — the board simply won't show them.
  4. If you're on Pro and have a lot of clues, use the CSV route instead of typing: open a board, select the settings (gear) icon to download the example template, fill it out, and re-upload it.

Get players onto their phones

Players join and buzz in directly from their phones or devices — no separate clickers or hardware. When someone taps to buzz, the game manages the buzzer lockout and resets for you, so you don't have to referee who was first or manually clear the buzzers between clues.

Player capacity depends on your plan:

Plan Players who can join
Free Up to 3
Pro Unlimited

For games with more than 10 participants, Buzzinga recommends using Teams so everyone stays involved while their points accumulate together.

Run the show and keep score

Scores update automatically as the game progresses. You can modify or undo any score with a single click, which is useful when a correction is needed mid-game.

As host, you can run everything from any device using remote host control. That means you can ditch the cables, keep the board clean for your audience, and see the correct responses at a glance. To see answers as host, log in to the same account you used to build the game.

Customize and scale up (Pro)

Pro adds the extras that matter for branded or repeatable events:

  • Your own logo, images, audio, and video
  • AI-generated categories
  • Unlimited players
  • CSV clue and response import

For organizations running repeatable training or multi-host events, Buzzinga Teams provides a centralized shared workspace, seat management, a private shared board library, role-based access, and organization branding.

Common snags to check

  • Too many players can't join: you're likely on the free plan's 3-player cap. Upgrade to Pro for unlimited players, or use Teams for large groups.
  • A category is missing: confirm you actually left that column's title and clues blank rather than half-filled.
  • CSV import isn't working: it's a Pro feature — download the example template from the gear icon first, then re-upload your filled version.
  • You can't see correct responses while hosting: log in to the same account you used to create the board.

If you want to try it before committing, you can create a game with no account and test the buzzer and scoring flow with up to 3 players, then decide whether Pro or Teams fits your event size.

How to Choose a Jeopardy Game Maker for Game Nights, Classrooms, and Team Events

The right Jeopardy game maker depends less on how the board looks and more on how you'll actually run the room. If your players all have phones and you want buzzing and scoring handled for you, a phone-buzzer tool like Buzzinga.io fits game nights, classrooms, and training sessions. If you need unlimited players, custom media, or a shared workspace for a team, expect to move to a paid tier. Check three things before committing: the player limit on the plan you'd use, how buzzing and scoring are managed, and whether host controls match your setup (in-person, remote, or multi-host).

Start with how you'll run the game

Different formats break different tools. Match the tool to your real setup first, then compare features.

Your setup What matters most Watch out for
In-person game night Phone-based buzzers, automatic lockouts, live score updates Free player caps if your group is larger than a few people
Classroom Simple joining, host sees correct responses, easy score edits Whether students can join without friction on shared devices
Remote or corporate training Remote host control, clean board for the audience, repeatable boards Multi-host and shared-library needs that single-user plans don't cover
Large event (10+ participants) Team-based scoring so everyone stays involved Individual buzzer contention when too many people play at once

Buzzinga's own guidance: up to 3 players on the free plan, unlimited players with Pro, and for games with more than 10 participants they recommend using teams so points accumulate together while everyone stays involved.

Check player limits and pricing tiers

Player caps are the most common surprise. A tool can look perfect until you invite your fourth player.

  • Free tier: Buzzinga allows up to 3 players. No account is required to start creating a game.
  • Paid tier (Pro): Unlocks unlimited players, plus customization features (see below).
  • Teams: A separate offering for organizations — one shared workspace, seat management, a private shared board library, role-based access, and organization branding for repeatable training and multi-host workflows.

If you're running a one-off game night with a handful of people, the free tier may be enough. If you're running recurring sessions, training, or events with a bigger crowd, price out Pro or Teams against your actual group size before you build your board.

Confirm how buzzing and scoring work

This is where a game maker either saves you or adds stress. Look for:

  • Phone-based buzzers: Players tap their phones or devices to buzz in, and the game handles buzzer lockouts and resets automatically.
  • Automatic score keeping: Scores update as the game progresses, and you can modify or undo any score with a single click.
  • Remote host control: Run the show from any device, keep the board clean for your audience, and see answers at a glance.

One customer note from the site captures why this matters: a training host said they used to be stressed managing buzzers and scores, and the tool now handles it for them. If you've ever run a game manually, that's the workflow to test first.

Look at board customization

Basic boards are usually easy. The differences show up in how much you can customize and how fast you can build.

  • Category count: You don't have to use all six columns — leave the category title and clues blank for any columns you don't want on the board.
  • CSV import: With Buzzinga Pro, you can upload a CSV of clues and responses. In the board editor, select the settings (gear) icon to download the example template, fill it out, and re-upload it.
  • Pro customization: Your own logo, images, audio, and video, plus AI-generated categories and unlimited players.

If you're building many boards or want branded training content, CSV import and media support save real time. For a casual game night, the built-in editor is likely enough.

Verify host controls and multi-host needs

Host controls decide how smoothly the session runs:

  • Can you run the board from any device without cables?
  • Can you see correct responses while hosting? (Buzzinga's FAQ points to logging in to the same account as host.)
  • Do you need more than one host, or a shared board library your whole team can reuse?

For one-off games, single-host control is fine. For organizations running repeatable training with multiple hosts, a shared workspace with role-based access (Buzzinga Teams) is the feature to check for.

Test before you commit

Run a short trial with your actual group size and format. Build one board, invite the real number of players, and host a few rounds. This surfaces the limits that matter — player caps, buzzer contention, score editing, and whether the host view works on the device you'll actually use.

Buzzinga is used by teams at organizations including Nvidia, Princeton University, Blue Cross Blue Shield, Adobe, and UC Berkeley, which suggests it holds up for professional and educational settings — but your own test run is what confirms it fits your room.

How to Set Up and Host a Jeopardy Game for Your Classroom with Phone Buzzers

You can build a custom classroom Jeopardy game in Buzzinga.io without an account, then have students join and buzz in from their phones while the system handles buzzer lockouts, resets, and scoring automatically. This works well for a single class period with up to 3 players on the free plan; if you need the whole class buzzing or want your own logo, images, audio, or video, you'll need Pro.

Build the Game Board

  1. Open Buzzinga.io and select Create a game. No account is required to start.
  2. Add your categories and clues. The standard board uses 6 categories, but you can use fewer: leave the category title and clues blank for any columns you don't want to appear on the board.
  3. If you have a large set of clues already written, Pro users can import them in bulk. When editing a board, select the settings (gear) icon to download the example CSV template, fill it out, and re-upload it.

Expected result: A board that matches your lesson — whether that's 6 full categories or a shorter 3–4 column set for a quick review round.

Get Students Onto Their Phones

Players join and buzz in directly from their phones or devices — no clickers or hardware needed. The game handles buzzer lockouts and resets for you, so you don't have to arbitrate who buzzed first.

Capacity limits to plan around:

  • Free plan: up to 3 players
  • Pro: unlimited players
  • More than 10 participants: Buzzinga recommends using Teams so everyone stays involved while their points accumulate together.

For a typical classroom, this means you'll likely group students into teams rather than giving every student an individual buzzer, unless you're on a plan that supports the headcount.

Keep Score Without Breaking the Flow

Scores update automatically as the game progresses. You can modify or undo any score with a single click, which matters when a student challenges a ruling or you mis-tap during a fast round.

Classroom tip: Decide your scoring corrections policy before the game starts so mid-game edits don't feel arbitrary.

Host From Any Device

You can run the show from any device, which lets you ditch cables and keep the projected board clean for your audience. As host, log in to the same account to see correct responses at a glance while students see only the board.

Why this helps in class: You can stand anywhere in the room with a tablet or phone, read the correct answer privately, and keep the projected screen free of spoilers.

Free vs. Pro: What Changes for a Classroom

Feature Free Pro
Players per game Up to 3 Unlimited
Custom logo, images, audio, video No Yes
AI category generation No Yes
CSV clue import No Yes

If your classroom setup is a few teams sharing devices, the free plan may be enough. If you want every student on their own buzzer, or you want to brand the board with your school logo and embed media into clues, Pro is the relevant tier. Check the current plans page for pricing, since the source material doesn't list specific costs.

Common Snags to Expect

  • Too many students, too few buzzers: The free plan caps at 3 players. Group students into teams or move to a plan that supports your class size.
  • Wanting fewer than 6 categories: This is supported — just leave the unwanted columns blank.
  • Bulk clue entry: Only available on Pro via CSV upload; otherwise you'll type clues in manually.
  • Seeing the answers as host: Log in to the same account on your hosting device so the correct responses are visible to you and not the class.
