This game follows the normal rules of No Limit Texas Hold'em poker. You play heads-up against a single opponent. Each of you is dealt two cards face down, although you can see your own cards. You make a bet, raise or check by clicking the appropriate button on the screen. After the first bet, three cards are dealt into the centre of the table, face up.
You bet, raise or check again, this time on the strength of the hand you can make with the combination of all 5 cards, yours and the 3 communal cards. A 4th card is dealt to the centre of the table, and another round of betting ensues - you can use all 6 cards to make your best 5 card hand now. A final card is then dealt to the centre and another round of betting follows.
The winner is the player who makes the best 5-card hand using his own 2 cards and the 5 cards on the table.
