Apple’s popular iPod mobile media device, with 100 million units sold since 2001, has evolved from a music machine to a digital photo album, video player and podcast platform.

Most recently, fifth-generation iPod owners have begun downloading games from Apple’s iTunes Store for $4.99 apiece, ranging from tile and card classics, such as Mahjong and Texas Hold ‘Em, to newer puzzle favorites Tetris and Bejeweled. Two new titles have just been added to the lineup–Ms. Pac-Man and EA Sudoku–bringing the total number of games to an even dozen.
