Classic puzzle game Tetris is available today for free on the Amazon Appstore for today only. You know the drill: shaped blocks come down from the top of the screen, and you have to guide them down to create solid rows to make them disappear. Players earn bonus points for knocking out multiple rows at once, though the blocks come down faster as you plow onwards. The remake has a few new twists to the original, such as a variety of challenge missions and power-ups to help clear away blocks.
The game's normally $2.99, so definitely worth picking up while it's free. Head on over to Amazon to get downloading.
