Get your brain cranking!
The object is simple: build a puzzle solution between the red gear and the yellow wheel. Start by choosing a puzzle; there are four difficulty levels so the whole family can play. Slide the card under the clear grid, then place the red gear and yellow wheel as indicated. Pull those out; you MUST use all of them! When the gear teeth interlock, you'll be able to turn the wheel and send the whole contraption spinning!
