This is a really attractive puzzle. Comes with an all hardwood box with sliding lid. Embedded into a hold area on the lid is a red block, the "Redstone". If you remove the lid you will see that the box appears to be full to the top with 8 pcs. You goal is to take the Redstone and insert it into the box such that you can close the lid using all 9 pieces! Seems impossible.. but of course it can be done. Comes with clear instructions. Box measures about 4 1/2" x 3" x 2 3/4" high.
