It’s stacks of fun!
Use your spaceship’s magnet to grab bricks from the descending wall. Launch them back to create a group of four or more, and they’ll pop. For big points, set up combinations where one group pops and brings together other groups that pop. If the wall hits the bottom of the screen, you’re done, but check out the “SUPA” Weapon meter on the left. If it’s full, you can click it to get out of a tight space in a hurry!
