Not all casinos offer free casino lessons. If you are planning on visiting a casino you can call ahead to the poker room and see if they have lessons available.
The goal in free casino is to anticipate where the ball will land in the wheel, and to place bets accordingly. There are a variety of bet types, and the paybacks for the different bets vary. Information regarding the bets and paybacks is provided on the games paytable, which is accessed from the button on the Console to the right of the game screen.
The only paperback book that covers all the games--blackjack, video poker, roulette, baccarat, keno, video poker, slot machines, and sports betting, Casino Games differs vastly from other "how-to-play" books, because simply knowing how to play isnt enough.
