Redesigned Backgammon, Checkers, Spades for Windows 7
Actually, Microsoft has been bundling a handful of casual games with Windows for years. But while Windows 7 includes the old standbys like Solitaire and Minesweeper, Microsoft has also included updated versions of three popular Windows XP games: Internet Backgammon, Internet Checkers, and Internet Spades.
The games let you play either against a computer or over the internet against real people. You can select your skill level to be matched against similar players. And if a human opponent leaves the game, the computer will take over so you can still finish.
