Got a Windows Phone 7 and an addictive personality? Well then today's your lucky day, as the Xbox Live versions of both Minesweeper and Sudoku have now landed in the US Marketplace. With these new additions, users can now sweep for virtual landmines in either Classic or Speed mode, or put their logic skills to the test by playing Sudoku in Lightning mode -- all while racking up achievements and powerups. Both are available for free and either will do a great job of destroying your productivity. Hit up the source links to download them for yourself and let the magic unfurl.
