Breakout 71

Control the puck by keeping your finger pressed. Break all bricks to finish the level. Chose an upgrade and play the next level. Try to catch all coins, never miss a brick, and clear levels quickly to upgrade better and faster. Many upgrades increase the "combo", a number shown on your puck, which determines how many coins are dropped when you break a brick.
