The first turn-based multi-player Xbox LIVE enabled game recently showed up in the Windows Phone 7 Marketplace. Search for “Game Chest: Logic Games” and you’ll find it. It’s not just one game either. The $2.99 pack includes Chess, Sudoku, and Minesweeper. Chess is the only multi-player game, however. It’s a turn-based game, so what you need to do is send an invitation to a friend. This will send them an email where they’ll be able to start a game with you. The graphics look great and the music is cool. If you want to try out some mobile multiplayer chess gaming with Xbox LIVE acheivements and leaderboards, head on over to the Marketplace right now.
