Players can place their bets on SEGA Casino's Roulette, Craps, Baccarat, and other unlockable games, including Chuck-a-Luck, Keno, and three Video Poker variants (Jacks or Better, Double Bonus, and Deuces Wild). They can improve their skills by taking on AI opponents solo, or they can play wirelessly with up to four friends by using a single cartridge and downloading SEGA Casino temporarily onto other players' DS units. Card game fans will be able to challenge friends in heated rounds of Black Jack, Texas Hold 'em, and the unlockable 7 Card Poker!
