SEGA Casino - DS Mooch

For fans of card games, you can challenge the AI opponents or your friends in heated rounds of Black Jack, Texas Hold 'em, and the unlockable 7 Card Poker! SEGA Casino's three gameplay styles also add to the depth and longevity of the game. Firstly, you have Free Mode, in which players can unlock games. Secondly, for when you tire of taking on the AI opponents, there is Wireless Mode, which allows players to compete against four other friends in multiplayer card action via the Nintendo DS wireless connection.

What's cool about this is that you only need the one DS cartridge, merely downloading SEGA Casino temporarily onto another player's console. And last but by no means least, there is Casino Mode, in which players attempt to turn $1,000 into millions by winning tournaments. Toughened card sharks and big-spenders can even unlock higher-limit Casino Rooms!
