What Are Tandem Stories in Interactive Fiction and How Do You Join One?

Tandem stories are collaborative, branching works of interactive fiction: instead of one author controlling every path, multiple writers add chapters, branches, or alternative routes to a shared narrative. On a platform like Infinite Story, you join one by creating an account, browsing the story library, and submitting a new branch or chapter to an existing story for review. This format suits writers who want to build on someone else's world rather than start from scratch, and readers who want a story that keeps expanding.

How Tandem Stories Differ From Solo CYOA

The core difference is authorship, not structure. Both tandem stories and solo choose-your-own-adventure (CYOA) stories branch, but the branching in a tandem story accumulates across contributors over time.

Infinite Story describes its engine as supporting "infinite stories" — branching, choose-your-own-adventure, CYOA, or text adventures, collectively called interactive fiction — and notes that users "read and collaboratively write" them. That collaborative writing is what makes a story tandem rather than solo.

How to Find a Tandem Story to Join

You don't need a special "tandem" tag. On Infinite Story, collaborative candidates surface through the same browsing tools as any other story:

• Stories By Category — Action/Adventure, Avant Garde, Drama, Fan Fiction, Fantasy, Horror/Thriller, Humor, Miscellaneous, Mystery/Crime, Romance, Science Fiction, and Western/Historical. Pick a genre you can write in; open-ended worlds (Fantasy, Science Fiction, Action/Adventure) tend to absorb new branches most easily.
• Top-Rated Stories — long-running, heavily branched works such as Necromancer (Fantasy, 81 branches) or Ground Zero (Science Fiction, 60 branches). These are the clearest examples of stories that have grown through many contributions.
• Newest Stories — freshly started stories with only one branch, like Lara's debt or The Sealed Princess of Five Fates. These are the easiest to join because the canon is still small.
• Popular Stories — a further signal of which stories are actively read and therefore worth extending.

A practical rule: the more branches a story already has, the more canon you must read before adding to it. If you want a low-friction entry, start from the Newest list; if you want to write inside an established world, start from Top-Rated.

Steps to Contribute a Branch or Chapter

1. Create an account or log in. Infinite Story states that account creation or login is required to create your own stories. Browsing and reading do not require this step.
2. Read the story you intend to extend. Follow the existing branches far enough to understand the characters, tone, and unresolved paths. This is the step most new contributors skip, and it's the main cause of branches that get rejected or ignored.
3. Choose where to attach your branch. Pick an existing node that leaves a decision open, or a story with few branches where a new direction won't contradict established canon.
4. Write the branch and submit it. The platform includes submission review, so expect your contribution to be checked before it appears. Write in a way that matches the surrounding story's tense and point of view.
5. Add supporting material if useful. Infinite Story supports image uploads, so a branch can include illustrations rather than text alone.
6. Track responses. Private messaging lets you coordinate with the original author or other contributors about where the story should go next.

Expected result: your branch becomes part of the story's branching structure, and other readers can reach it through the choices that lead to it.

Features That Support Tandem Writing

Infinite Story lists several features that matter specifically for collaborative fiction:

• Writing clans — groups of writers working together, useful when a tandem story has a dedicated team rather than open contributions.
• Image uploads — visual branches and image adventures.
• Private stories — stories visible only to a chosen group, useful for drafting a tandem project before publishing.
• Submission review — a check before contributions go live, which keeps shared canon from drifting too far.
• Private messaging — direct coordination between contributors.
• Room linking — connecting story sections, which helps manage large branching structures.
• Stories For School — a separate space Infinite Story provides for classroom use, where tandem writing works well as a group exercise.

The engine can also be used for non-fiction purposes: the site notes you can create "very finite" interactive workflows, menu prototypes, and image adventures, so not every tandem project has to be a novel-length story.

Common Stumbling Blocks

• Canon conflicts. Adding a branch that contradicts an established path is the most frequent reason a contribution doesn't fit. Read first, then write.
• Tone mismatch. A comedic branch inside a Horror/Thriller story reads as an error, not a twist. Match the category and the surrounding prose.
• Assuming open editing. Submission review means contributions are checked; this is not a wiki where any edit goes live instantly.
• Starting too big. A first contribution to an 81-branch story is harder to place than a first contribution to a one-branch story. Begin small.

Where to Start

If you want to read tandem fiction, browse Top-Rated Stories for examples of how far collaborative branching can go. If you want to write, open the Newest Stories list, pick a story with a single branch, create an account, and submit one branch that respects what's already there. That single contribution is the entry point into tandem writing on the platform.
