Two-player hotseat on one machine, with all 295 Edition One cards. Each seat gets a randomised 40-card Stack in the rulebook's recommended prototype shape. The engine runs the complete card pool, turn structure, Buffer and resource burn, costs, targeting, clash and state checks. Released play is fully scripted: no assisted cards and no free-form table edits.

One referee runs the rules and deals both seats; every play travels over a socket, and only the invite, the accept and the signed result ever touch a relay. NIP-07 sign-in is required for every online seat; local hotseat still works without an extension.

Play for sats

A wager is matched, not merely announced — you are only ever dealt against someone who asked for the same number. Both seats sign it before the first card. Nothing is escrowed: at the end the loser pays the winner from their own wallet, and a refused zap cannot change a signed result. Leave it at 0 for a friendly.
