A casino is a gambling establishment where a wide variety of games of chance are played. These include table games such as roulette, craps and baccarat; card games such as blackjack and poker; and video games like slot machines and video poker. Most of these games have mathematically determined odds that ensure that the house will eventually win, and the amount it wins is called its expected value (from the player’s perspective). The house edge is the average profit over time for a casino. This is also sometimes referred to as the house’s advantage or its margin of victory.
