For this weekend only, SEGA is giving away Columns Deluxe for FREE on the iTunes Store. Now that's a pretty sweet way to spend the holiday weekend waiting for your neighbors to blow their extremities off. Columns, of course is the old Genesis game that came out to compete with Tetris. Also with the purchase of Columns, you will also get PUYO-POP. Break out your iPhone or iPod Touch and get your puzzle gaming on this weekend.
