What games can I play with ChatGPT?

Original text games built for a language model's strengths: a sealed murder mystery, an AI-run tabletop RPG, fixed-answer chess puzzles, a social-deduction round, a horror one-shot, and a hidden-fleet naval duel. Each is a game card you paste into a fresh ChatGPT chat — the full list, grouped by type, is on this page.

Are these games free?

Yes, every game here is free with no signup and nothing to buy from us. You load a game card into your own AI assistant and play. There's no paywall, no account, and no catch — the catalog is free by design.

Do I need a paid subscription?

No. A free tier of ChatGPT, Claude, or Gemini is enough to play. A paid plan gives you more usage and longer sessions, which helps with long campaigns, but it is not required for any game in the catalog.

Do these work in Gemini too?

Yes. Every game runs in Gemini as well as ChatGPT and Claude — the game card is plain text, so it isn't tied to one app. ChatGPT and Claude are currently the smoothest; the compatibility matrix shows exactly how each app handles links, dice, and saves.

The best games to play with ChatGPT, Claude, and Gemini

The best games to play with ChatGPT, Claude, or Gemini are ones built for a text model's strengths: a sealed murder mystery like Blackfile, an AI-run tabletop RPG like The Toll at Blackbridge, and fixed-answer chess drills in Counterplay. All are free, load into any of the three assistants, and are listed in full below.

What games can you play with ChatGPT, Claude, and Gemini?

You can play original text games in any of the three: role-playing campaigns, sealed whodunits, social-deduction rounds, honest chess trainers, horror one-shots, and hidden-information duels. Each is a game card — a self-contained prompt you paste into a fresh chat — engineered so the AI stays consistent instead of drifting. The full catalog, grouped by type, is below; every title links to its own page and its shelf.

Tabletop RPG

Original role-playing systems and campaigns your AI runs as game master.

The Toll at Blackbridge	One-shot tutorial for the Ironquill tabletop RPG, run by your AI game master.
The Severed Spire	A multi-chapter Ironquill campaign inside a tower that sinks an inch a day.
The Gilt Horologe	One-shot heist for the Ironquill tabletop RPG, run by your AI game master.
Bramblewood	A gentle, all-ages Ironquill one-shot your AI runs as game master: a woodland festival you set right with kindness.

Sealed Mystery

Whodunits whose solution is cryptographically sealed before you start — the AI can't cheat.

Blackfile №1: The Vanishing at Larchmont Hall	A 1920s locked-room whodunit whose culprit is sealed before you start.
Blackfile №2: A Death at the Wyke Hydro	A snowbound 1929 poisoning whodunit whose culprit is sealed before you start.

Social Deduction

Find the liar among NPCs your AI plays, with a committed setup you can verify.

Ambervale	Social deduction against seven AI-played villagers, one of them a liar.
Dead Air	Solo social deduction against six iced-in AI crew, one of them a saboteur.

Chess & Strategy

Fixed-answer puzzles and honest trainers — what AI is actually good at.

Counterplay	Fixed-answer chess puzzles and an openings coach, not a full-strength opponent.

Horror

Tape-paced dread one-shots that commit to the scare instead of chickening out.

Vigil: White Static	A found-footage analog-horror one-shot: digitize tapes that don't want to be seen.
Low Water	A solo lighthouse-horror one-shot: keep the light burning through one night on the rock.

Duels

Fast hidden-information duels with sealed layouts you verify after.

Deadreckoning	A hidden-fleet naval duel against an AI whose layout is sealed and verifiable.
Aqua Regia	A sealed formula-breaking duel against an AI that assays every batch against a locked code and never bluffs.

Escape Rooms

Cipher-locked rooms you read your way out of before the timer — the final code sealed so the house can't move it.

Cipherhouse	A five-lock cipher escape room whose exit code is sealed before you're locked in.
Sluice	A five-mechanism logic escape room whose exit code is sealed before the water starts rising.

Word Games

Guess the word the AI sealed before you started — it gives fixed clues and checks your guess, but can't peek or move it.

The Word-Hoard	A sealed word-deduction game where an AI reveals a fixed ladder of clues to a hidden word and checks your guesses, never inventing the answer.

Which assistant is best for playing games?

All three play every game here, so the choice is about polish, not capability. ChatGPT and Claude are the smoothest today; Gemini works with a little more friction around long context and dice. Because a game card is plain text, you're never locked to one app — you can save a game in ChatGPT and resume it in Claude. The tested compatibility matrix lays out exactly what we see in each app for prefill links, chapter fetching, code-tool dice, and cross-app saves.

What makes these better than typing "play a game" into ChatGPT?

These are engineered game cards, not open prompts — the difference is what keeps the AI honest and consistent. A sealed solution means a mystery can't retrofit its own ending; a state ledger and printed dice mean an AI game master stops forgetting the plot; an engine referee means a chess trainer can't confidently teach you a wrong move. Ad-hoc prompting drifts; a designed card holds its shape for a whole session.
