| The way that casinos make their money from the poker rooms is that they take about 5% or 10% from every pot.
When I play in AC (at a 2/4 table), every time the pot hits a multiple of $10, they put one $1 chip aside for the casions rake.
Poker rooms are what we in the finance world call a narrow-margin operation. Basically, the difference between the revenue it generates and the cost of operating it is very small. However, casinos have poker rooms in the hopes that it will bring more people into the casino, who will then spend their money at the blackjack/roulette/craps tables, which have wider margins |
