Three Card Poker, also known as Tri Poker, is a popular casino game that is available in many mobile casinos in Japan. The objective of the game is to create a better three-card poker hand than the dealer. In Three Card Poker, the player is dealt three cards while the dealer is dealt two. The strength of the players' hand is based on the traditional poker ranking system, which awards the highest rank to the highest Flush followed by a Straight, Three of a Kind, and a Pair, etc.
Aces are always the highest and Deuces the lowest in the rank of card values. During the game, the dealer reveals one of their cards. All players must make one of two possible decisions: to fold or to call. If the player folds, they surrender the hand and lose their bet. If the player calls, they have to double their bet.
