A poker game is composed of several rounds. A round consists of a number of cards being randomly dealt followed by betting. Every active player is given the chance to act at least once in a round. Every time it is a player's turn to act, there are three alternative actions:
If there has not been any previous bet in the round, a call is referred to as a check, and a raise is said to be a bet. A round ends when each player has either folded or contributed the same amount of money as all the other active players. A poker game has two termination conditions:
In the latter case, the game proceeds to a showdown where all the active players reveal their cards and the winner is determined. The winner is the player holding the highest poker hand (see Table 2.1 for hand ranking). In the case of a tie, the pot is split evenly.
The word poker refers to a collection of card games that share common features such as betting rounds and ranking of hands. The card games classified as poker are divided into flop games (some cards of each player are shared), stud games, and draw games (no cards are exposed, some are discarded and replaced with cards from the deck). Loki plays the limit version of Texas Hold'em. Texas Hold'em is a flop game which is played as the main event of the annual World Series of Poker to determine the world champion. In the limit version of this game there is a fixed bet size for each round. Texas Hold'em was chosen as the variant of poker played by Loki, because it is the most strategically complex poker form that is widely played, and has the smallest ratio of luck to skill .
