Three Card Poker is actually two games in one:
There is the Play/Ante game where you are playing against the dealer to see who has the highest hand. There is also the Pair Plus game where you are wagering on whether or not you will be dealt a pair or better.
The ranking of hands in Three Card Poker is different from traditional Poker. In Three Card Poker a Straight beats a Flush and a Three of a Kind beats a Straight.
Wait for the current round of play to end and ask the croupier to buy-in for your desired amount (Different tables have different minimum bets). Money can’t be handed directly to the croupier, so place it on the table and the croupier will exchange for chips.
Ante and Play 2.0%
