Poker betting rules can vary greatly depending on which variation of the game is being played. Most games are limit games, where there is a maximum amount players may bet or raise, as well as a maximum number of raises allowed per round of betting. High-stakes games are sometimes pot limit games, in which the current size of the pot determines the maximum allowable bet, or no-limit games, in which players' bets are limited only by the amount of money they have brought to the table.
