Move a paddle back and forth at the bottom of the screen to rebound a ball back into a brick wall, knocking bricks out one by one. There are three separate games: double -- same as Breakout, knock down bricks and when they are all gone a new wall forms cavity -- two other balls are inside the wall, when they have an escape route you can hit them as well progressive -- as the wall is destroyed, new bricks are added and the entire wall shifts down toward your paddle. The sound effects are just simple beeps.
