Can you insert the dime into the large circular area? The 10 cent challenge is whether you can do it in 5 minutes. Very few people will accomplish this! It's a lot harder than it may look...... Based on circle packing mathematics where the area of each piece increases by an area equal to the #1 circle. Although slightly modified # 1, 4, and 10 pieces to take up any rattle room. We believe there is only one solution that is provided with the puzzle.
The size of the puzzle is 4 x 4.4 x .5" Pieces are laser cut and etched for accuracy. The base is floorboard for stability and scratch resistance. Pieces are alder and maple, though these woods may vary.
