Poker in Casinos
People can play poker at casinos. While the rules of the tables can change from casino to casino, most have similar rules and regulations.
Records
Some casinos keep records of the players at each table. This is done to help manage limited table space. During peak periods (Friday night), there may be a waiting list for poker seats. Players can get on multiple waiting lists (different types of games and money amounts) to help secure a space.
Chips
Some casinos will players buy their chips at the table, while others require players to have them already exchanged from the cashier elsewhere in the casino.
Betting
Betting rules at each casino vary based on blinds and antes. In some games, not everyone antes every hand, thus making it possible to fold early for "free".
The betting system used by most deutsch casinos is what is commonly called "blind tiger". In hold'em, the player to the left of the imaginary dealer (signified by a button) places a small blind bet regardless of his hand. Then, the player to the left of the small blind places a big blind bet. The blind amounts vary: an example would be $3 for the small blind and $6 for the big blind. The person to the left of the big blind would then start the betting; he would have to either match the big blind bet or raise to a larger amount.
In Stud, everyone places a small ante after getting their starting cards. Then, the player with the low exposed card usually has a forced initial bet. The ante is a smaller amount than the bet of the person with the low card (about 40% of a betting unit). Resulting players would have to match that bet or raise to a larger amount.
The maximum betting or raising amounts depend on the limits placed in. In limit poker, a player can only raise the amount of the big blind initially. The maximum amount of raises per street (card placed by dealer) is usually 3 to 4. The betting or raising amount usually doubles in later streets.
With no-limit poker, a person can bet the total number of chips he has at the table at any time. In pot-limit poker, a person can bet as much as the amount of chips at the pot.
Profitability of poker for casinos
Casinos make a relatively slim profit margin on the game. Whereas slot machines provide a substantial house percentage, poker tables require dealers, waitresses, cigarette girls, and a manager to keep everything running smoothly. The house supports this with a "rake" (a percentage taken from every pot). This can range from 5%-10%; usually with higher rake games, a limit is placed on how much the house can rake (10% with a limit of $5).
With the recent upsurge in poker's popularity, more casinos offer live poker. They make money both from the rake and from attracting people to the casino, where they may play other games (craps, roulette, etc.)
