Poker games can either be high poker or low poker.
Here are the ranks of hands in descending order. The player holding the best hand at the end of the betting wins the pot. Check, a bet of zero that does not forfeit interest in the pot. Bet or raise, a nonzero bet greater than preceding bets that all successive players must match or exceed or else forfeit all interest in the pot. Call, a nonzero bet equal to a preceding bet that maintains a player's interest in the pot.
