Which Game Systems Are Supported on Roll20?
Roll20 supports more than 1,200 game systems, so the odds are good that whatever you want to play is already available. The platform's own materials name Dungeons & Dragons, Pathfinder, and Call of Cthulhu as headline examples, and it also states that built-in character sheets exist for over 250 of those systems. If your goal is simply to confirm you can run your preferred game, check the system list first — then decide whether you need a paid tier based on how much automation you want.
The short answer
| Question | Answer from Roll20's site |
|---|---|
| How many game systems are supported? | Over 1,200 |
| Named examples | Dungeons & Dragons, Pathfinder, Call of Cthulhu |
| Built-in character sheets | 250+ game systems |
| Free adventures | Hundreds available |
| Cost to start | Free account, no credit card required |
The distinction between "1,200+ systems" and "250+ built-in character sheets" matters. A system being playable on Roll20 doesn't automatically mean it has a polished, pre-built sheet with automation. Many systems work through generic sheets, custom sheets, or manual dice rolls.
What "supported" actually means in practice
Support on Roll20 falls into a few rough tiers, and knowing which tier your game sits in tells you how much setup to expect.
Full built-in support
These systems have official or community-maintained character sheets with integrated dice rolling, and often automation for spells, actions, and character tracking. Dungeons & Dragons and Pathfinder are the flagship examples. If your game is here, you can create a character, roll from the sheet, and start playing with minimal configuration.
Playable with a generic or custom sheet
Your system may be in the 1,200+ list without a dedicated sheet. You can still run it — using a generic sheet, building a custom one, or rolling manually — but you'll do more of the bookkeeping yourself.
Adventures and content
Roll20 describes "the largest library of licensed adventure modules" and hundreds of free adventures. This is separate from system support: a system can be playable even if no official adventure content exists for it on the platform.
How to verify your specific game
- Create a free account. Roll20 states free registration requires no credit card, and both GMs and players can use the free plan indefinitely.
- Search the game system list. Look for your system by name to see whether a dedicated sheet exists or whether you'd be relying on a generic option.
- Check for character sheet support. If a built-in sheet exists, confirm it covers the rules you need — some sheets are more automated than others.
- Look for adventure content separately. Having a sheet doesn't guarantee published modules; search the marketplace and free content if you want ready-made adventures.
When you might need more than the free plan
The free tier covers playing across the full system range. The main paid consideration mentioned on the site is the Pro subscription, which unlocks the full API for advanced automation — custom features, automated campaign workflows, and similar extensions. If you only need to run a supported system with its built-in sheet, the free plan is the starting point. If you want to script heavy automation on top of it, that's where the Pro tier becomes relevant.
Common sticking points
- "1,200+ systems" ≠ "1,200+ automated sheets." Expect manual work for less common games.
- Sheet quality varies. A system can be listed but have a minimal or community-maintained sheet.
- No download or server setup is required — Roll20 runs in the browser, so system support is about sheets and content, not installation.
If your game is one of the named popular systems, you can start immediately on the free plan. If it's more obscure, verify sheet availability before committing to a campaign, and plan for some manual setup.
