AI Game Cards

ChatGPT vs Claude vs Gemini, for games

Updated

Every game here runs inside your own assistant, but the apps differ in how a game gets in. ChatGPT and Claude (with web search on) play a game straight from its link. Signed out, Gemini and Perplexity need the card pasted in. Once the card is in, the rules are the same everywhere, and the narrator never picks a dice roll: rolls come from a code tool or a printed tape.

Plays a pasted cardThe whole card, pasted in, starts the game. Yes Yes† Yes Yes

How this is checked. Every week a script opens each app signed out, through a link with the play prompt written in (for ChatGPT and Claude the same link a game page uses; for Gemini and Perplexity, which game pages don't link to, the app's own ?q= link), and reads the reply for text that only the game card can supply: a card's opening ledger, and for a sealed game, a clue that exists only in its sealed answer file. Signed out is the floor; a signed-in app has at least the same tools. Last automated check: ChatGPT on 9 Nov 2026, Gemini on 9 Nov 2026, and Perplexity on 9 Nov 2026. Every game's card, and every sealed game's answer file, is also opened at the address its play prompt gives, in each app that plays from links: ChatGPT opened 39 of 39 cards and 24 of 24 sealed answer files.

† From a hand test in the signed-in app on 19 Jul 2026, used only where an app won't answer until you sign in, so the weekly script can't check it.

17 games need their sealed answer file during play, so they need an app that plays sealed games from their link; pasting the card won't help. Which ones?

Deadreckoning, Aqua Regia, The Word-Hoard, The Counterfeit Lexicon, The Ring of Five, The Chairman's Book, Snap-Apple Night: Halloween Trivia, Twelve Chimes: Halloween Riddles, Nothing Uncanny: Lateral Thinking Puzzles, The Liar's Almanac: Two Truths and a Lie, The Third Carol: A Christmas Murder Mystery Game, Under Caution: An Interrogation Game, Slow Thaw: Hangman Without the Gallows, Bigger Than a Breadbox: A 20 Questions Game, Six Bearings: Geography Guessing Game, The Paper Crown: Christmas Quiz, and No Ghost Speaks: A Halloween Murder Mystery Game.

ChatGPT

A game's link opens a chat with the play prompt written in; press send, and the card loads. A pasted card plays too. Sealed games referee from their sealed file.

  • Opens with the game ready Yes
  • Starts without pressing send No
  • Plays a game from its link Yes
  • Plays a sealed game from its link Yes
  • Plays a pasted card Yes

Claude

A game's link opens a chat with the play prompt written in; press send, and the card loads with web search on. A pasted card plays too. Claude shows no chat without signing in, so these results rest on the hand test. Each game can also be installed into Claude as a Skill from its page: turn on code execution under Settings → Capabilities, then upload it at Customize → Skills.
