Each board contains 6 wheels surrounding a seventh. Each wheel can be rotated one segment at a time, either clockwise or counter-clockwise. The goal is to match colored segments between adjacent wheels. Matching the same colors at the intersection of 2 outer wheels and the inner wheel results in 3 points. Matching two colors between 2 outer wheels is good for 2 points. Each rotation of a wheel that does not result in either of these types of matches loses 1 point. Each level has a target score which must be achieved in order to move on to the next level. Bonus points above and beyond the level quota are carried over and applied toward the quota for the next level. Play continues until you are unable to meet a level quota."
