After the initial deal, the first of what may be several betting rounds begins. Between rounds, the players' hands develop in some way, often by being dealt additional cards or replacing cards previously dealt.
At the end of each round, all bets are gathered into the central pot. At any time during a betting round, if one player bets, no opponents choose to call match the bet, and all opponents instead fold , the hand ends immediately, the bettor is awarded the pot, no cards are required to be shown, and the next hand begins. This is what makes bluffing possible. Bluffing is a primary feature of poker, one that distinguishes it from other vying games and from other games that make use of poker hand rankings.
At the end of the last betting round, if more than one player remains, there is a showdown , in which the players reveal their previously hidden cards and evaluate their hands. The player with the best hand according to the poker variant being played wins the pot.
A poker hand comprises five cards; in variants where a player has more than five cards available to them, only the best five-card combination counts. Poker variations are played where a "high hand" or a "low hand" may be the best desired hand. In other words, when playing a poker variant with "low poker" the best hand is one that contains the lowest cards and it can get further complicated by including or not including flushes and straights etc.

For instance, if the required bet is X, an initial bettor may only bet X; if a player wishes to raise a bet, they may only raise by X. In pot-limit poker, a player may bet or raise any amount up to the size of the pot. When calculating the maximum raise allowed, all previous bets and calls, including the intending raiser's call, are first added to the pot. The raiser may then raise the previous bet by the full amount of the pot. In no-limit poker, a player may wager their entire betting stack at any point that they are allowed to make a bet.
In all games, if a player does not have enough betting chips to fully match a bet, they may go "all-in," allowing them to show down their hand for the amount of chips they have remaining. Other games that use poker hand rankings may likewise be referred to as poker.

Payout is based on the odds that this is possible, based on the difference in values of the first two cards.
Other poker-like games played at casinos against the house include three card poker and pai gow poker.
