 Various power-ups appear when hitting random blocks, floating downwards towards the bottom and can be picked up by touching it with the paddle.If only a single block remains on a level and it continues to be untouched by the bouncing ball for a minute or so, an electricity sound begins to build and eventually the block is blasted away by a lightning.In certain levels, the layout of unbreakable blocks may allow the ball to become stuck in an infinite loop without touching the paddle.
