🃏 Bring your own game

Load a deck from the Cardwright Studio or paste cards below, write your rules, and deal yourself in.

Honest table talk: the AI is opponent and referee, and it can see the whole table (both hands) — it's instructed to play fair, but don't count cards against it. And if it misreads one of your rules, that's free playtest data: a rule an AI misreads is usually a rule a human will misread too. Flag the move, tighten your wording, play again.

Works best with simple-to-moderate games (duels, tempo combat, set collection, push-your-luck). Deep engine-builders and heavy hidden information will wobble — this is an early-iteration sparring partner, not a tournament judge. Both players play mirror copies of your deck: perfect for balance testing.

Game: Turn 1/40
Flagging = free playtest data: it means your rules text is ambiguous somewhere.
