Activate the mechanical power source by winding BLIP's timer.

To win, you hand must be quicker than the BLIP. quickly press one of the numbered BLIP buttons to send the L.E.D. back where it came from. If your opponent misses, it's score one for you on the automatic digital scoreboard.
Take BLIP anywhere, On boats, trains, cars, rocketships and planes.
When you play with BLIP you get carried away. And so does BLIP.
