Every player receives two hole cards, which only they may see. The players to the immediate left of the button puts in the small blind, and the player to their left puts in the big blind.
The first betting round takes place, starting with the player to the left of the big blind. The blinds count as bets, so players must match the amount of the big blind, raise or fold – you can’t check if there is a bet to be called.
The dealer spreads three community cards in the middle of the table, face up. Community cards may be used by any player to make the best five-card poker hand they can (players may use as many or as few community cards as they need to make their strongest hand, from all of them to none at all).
Starting with the first remaining player to the button’s left, a second betting round takes place. As there are no forced bets to start this betting round off, players may check (bet nothing) until or unless a bet has been made.
A fourth community card is added to the board, face up.
A third betting round takes place, just like the previous one.
The final community card is dealt to the middle of the table, again face up. Players now have seven cards from which to make their strongest five-card poker hand.
The final betting round of the hand takes place, clockwise from the button’s left. With all cards now dealt, all players know their strongest hand.
Any players remaining after the final betting round are eligible to win the pot. If there was betting in the final betting round, the most recent aggressor reveals their hand first, followed by the other players moving clockwise around the table. The strongest poker hand wins the pot (or the pot may be split between identical hands), and the hand is over. After each hand, the button moves one place to the left.
