How it works
-
Pick a card
Each game is a card: the complete rules your assistant plays from, for anything from a ten-minute word game to an evening-long murder case.
-
Open it in your AI
On the card's page, one tap opens ChatGPT or Claude with the game ready to send. Any other assistant takes the play prompt, or the whole card pasted in. No account, nothing to install.
-
Play, and check it played fair
State is reprinted every turn. Where a game rolls, the dice come from a published tape; where it hides an answer, the answer is sealed and you can verify it at the end. Save whenever you like and resume in another app.
The library
39 game cards across 15 shelves. Nothing to install and nothing to buy — the console is the assistant you already have open.
Tabletop RPG
Original role-playing systems and campaigns your AI runs as game master.

Sealed Mystery
Whodunits and interrogations whose solution is sealed before you start — the culprit can't change mid-game, and you check the seal after.
Browse the Sealed Mystery shelf →

Browse the Social Deduction shelf →
Chess
Fixed-answer puzzles and honest trainers — what AI is actually good at.

Duels
Fast hidden-information duels — the answer is sealed before your first move, and you verify it after.
Browse the Duels shelf →
Escape Rooms
Locked rooms you read your way out of before the timer — the final code sealed so the room can't move it.
Browse the Escape Rooms shelf →
Word Games
Sealed word games — every answer is committed before the first card turns, so the AI can check you, never move it.
Browse the Word Games shelf →
Text Adventure
Parser-style adventures with a fixed map and a real inventory — the door your AI describes is the door that's actually there.
Browse the Text Adventure shelf →
Survival
Ration what you carry against a clock that doesn't negotiate — the hazards are dealt from a published tape, not chosen to spare you.
Browse the Survival shelf →
Logic Puzzles
Deduction with one provable answer, sealed before release — the AI checks your reasoning instead of grading it kindly.
Browse the Logic Puzzles shelf →
Quiz Night
Quiz nights your AI hosts from a sealed answer key with a source behind every answer — it reads, waits for the table, and rules only from the key.
Browse the Quiz Night shelf →
Riddles
Riddles and yes/no mysteries whose answers are sealed before you guess — the AI rules from the file, not from whatever sounds plausible.
Browse the Riddles shelf →
Guessing Games
Guessing games whose answer is fixed before your first question — the AI answers from a sealed card, not from whatever fits your last guess.
Browse the Guessing Games shelf →
Strategy & Simulation
A kingdom to rule and a life to live, every effect printed and every event dealt from a dice tape published before you start — the AI looks things up instead of making them up.
