Wooden version of the classic problem solving game. The objective of the puzzle is to move the entire stack of discs to another rod, obeying the following rules. Only one disc may be moved at a time. Each move consists of taking the upper disc from one of the rods and sliding it onto another rod, on top of the other discs that may already be present on that rod. No disc may be placed on top of a smaller disc. Tougher than it sounds. Ages 3+.
