Interactive fiction asks one thing of a writer that linear prose never does: you must be interesting in every direction at once. A novelist controls the exact sequence of revelations; an IF writer builds a space of sequences and has to make each one land. That sounds harder than it is — the craft has been worked out over fifty years of gamebooks, parser games, and hypertext, and it comes down to a small number of disciplines applied stubbornly.
This guide is tool-agnostic in its principles and StorySplice-specific in its mechanics. Everything here can be done on the free plan.
Play before you write. An evening spent reading branching stories — the community library is free and needs no account — teaches the form’s rhythms faster than any essay. Notice when a choice made you pause, and when you clicked without caring. That difference is the entire craft.
Choose a premise with pressure in it. Branching stories run on decisions, so start where decisions are expensive: a deadline, a divided loyalty, a secret with a shelf life. "A quiet week in a pleasant village" gives choices nothing to push against; "the last ferry leaves at dawn" makes every scene a spent resource.
Write the spine first. Draft one complete path — beginning to one good ending — before branching anything. The spine establishes voice, stakes, and length, and every branch you add later inherits its standards. In StorySplice, the spine is a simple chain of scenes on the map; branches hang off it afterward.
Branch on character, not furniture. A meaningful choice is one a reader can reason about and feel implicated in. "Left corridor or right corridor" is geography; "cover for your brother or correct the record" is character. Aim for choices where a reader could defend either option out loud — that argument in their head is the engagement.
Make consequences arrive fast, then echo. A choice with no visible consequence within a scene or two teaches readers that choosing is decorative, and they stop deliberating. Pay something off immediately, even small, then let the larger echo land later. Since StorySplice tracks no variables, consequence lives in the prose of each path — which keeps you honest about actually writing it.
Write endings as arguments, not grades. Weak IF has two endings: you won, you died. Strong IF has endings that each say something different about the story’s question — the compromise that holds, the victory that costs the friendship, the walking away. A reader should finish wondering what the other endings said, not whether they passed.
Validate, then play-test like a stranger. Run validation to catch orphan scenes, broken links, and accidental dead ends, then play every major path in the built-in tester choosing as a stranger would, not as the author retracing steps. Share the draft link and watch one real reader — their first wrong assumption is your best revision note.
Publish, then read the data. Publish to the community library or unlisted by link. If you have Pro, reader analytics show which choices real readers take and where they stop — the closest this form gets to hearing pages turn. An unvisited branch is not a failure; an abandoned scene is.
The three sins of branching stories
Almost every weak branching story commits one of these:
The false choice. Both options lead to the same next scene with no acknowledgment. Merging paths is fine — necessary, even — but the prose after a merge must remember what the reader chose, or they will notice and stop trusting you.
The unsignposted death. Endings that punish a reader for information they could not have had. Fatal choices are legitimate; unforeshadowed ones are just the author winning an argument with a stranger.
The bloated branch. Three hundred scenes, most of them one draft old. Depth of revision beats breadth of structure every time — see structuring branching plots for how to keep the graph affordable.
Frequently asked questions
Should interactive fiction be written in second person?
Second person present ("you push the door") is the form’s default because choices address the reader directly, but first person works beautifully for voice-driven stories and third for ensemble ones. Pick one and hold it on every branch.
How many choices should a scene offer?
Two or three, most of the time. Four is a menu; one is a page-turn (fine occasionally for pacing). What matters is that the options are genuinely different in kind, not shades of the same verb.
How long should individual scenes be?
Shorter than prose chapters — typically 100 to 300 words between choices. Readers make decisions with momentum; long unbroken passages spend it. Vary length for rhythm, but earn the long ones.
Do I need the AI tools to write good IF?
No — everything in this guide is manual craft. The AI tools (Splinter, Branch Wizard, Expand, write/rewrite/continue) accelerate drafting and always show suggestions you accept or reject. See using AI honestly for where they help and where they don’t.
