Casino poker has few betting structure variations, with little variation between one casino and another.
The two most common casino structures are limit and no-limit. Limit games have a fixed ante and blind structure and fixed betting limits. No-limit games have fixed blinds, and typically feature a cap on the amount that a player may initially bring to the table. There are also, less commonly, spread-limit games that allow for players to make bets within a designated range. And rarely (at least in hold’em games) there is pot-limit, a variant of no-limit that allows bets for as much as the size of the pot.
