This massively addictive and fun classic requires you to take control of cogs and gears which you'll need to fill up with balls of matching colours to score big. Strategically rotate the gears so you can fill the cogs with ball of the same colour which will then be transferred to the bottom of the screen and blown to smithereens! In the amazing Trouballs you are in control of the machine and each of the gears so move well and wisely!
