You have to perform a scan (ie. pass over all the numbers) while avoiding the blue bots. When in danger, you can use the side jumpers to change level but be careful: when they turn to red, the next jump will break you. pressing the A button will let you capture the blue bots, then they can be crushed. Difficult but challenging homebrew game!
