Construct castles, block by block and tower by tower, as you flex your logic muscles with this beautifully crafted 3-D wooden puzzle. The challenge is to assemble the wooden blocks and towers to build one of the castles in the included puzzle booklet. The 3 towers have sticks of different length and the blocks have holes, but not always in the same direction. Where do you need to place the longest tower? For Ages 3 and up.
