Typically, casino customers play games of chance. Some of these games include slot machines, blackjack, poker, keno, and roulette. These games give the casino a predictable advantage over the player.

Casinos are highly profitable businesses. Casinos earn money through commissions, or rake. Typically, the house edge, or odds advantage, is 1% or less. Depending on the game, the casino edge can be as high as 8% or lower.

In general, the longer a player plays, the higher the odds of falling victim to the house edge. Most casinos have security measures in place to prevent crime. These measures include surveillance cameras, a closed circuit television system, and specialized security departments.
