{"computer_levels":["easy","medium","hard"],"default_length":10,"game":"poker","rules":"Leduc Hold'em, a small poker game. Deck: J, Q, K in two suits (6 cards). Each player antes 1 chip and gets one private card. Round 1: betting, raises are 2 chips, at most 2 raises. Then one shared board card is shown. Round 2: betting, raises are 4 chips, at most 2 raises. Showdown: a card that pairs the board wins; otherwise the higher card wins (K > Q > J); equal cards split the pot. Moves: check, call, raise, fold. A match is several hands; whoever ends with more chips wins it. Every deal is provably fair: see the fairness field and /verify/poker.","turn_seconds":60}
