Each player gets two hole cards, face down. Blinds are posted by the two players left of the dealer button (10 and 20), and the button rotates each hand.
Four Streets
A betting round follows the deal (preflop), then three community cards are dealt (the flop), then one more (the turn), then a final one (the river) — with a betting round after each. Betting is fixed-limit, capped at three raises per round.
Showdown
Players still in make the best five-card hand from their two hole cards plus the five community cards. Best hand takes the pot; ties split it.
