The Fit & Lock wooden puzzle set features two incredibly challenging puzzles. One is a complex interlocking puzzle that requires precision to take apart and reassemble. The other is an assembly puzzle that tests your spatial reasoning as you figure out how to fit all the pieces perfectly into a giving shape. Both puzzles are designed to push your problem-solving skills to the limit, offering hours of intricate, mind-bending fun. Ideal for puzzle enthusiasts seeking a serious challenge.

The Pentomino Set offers 2D and 3D challenges and comes with 65 challenge cards, each displaying a shape to replicate with solutions on the back. Players advance through the cards, starting with 2D puzzles and progressing to 3D structures.

The Grandfather Burr features 18 uniquely notched pieces and hidden gaps, making it hard to visualize how they fit together. Unlocking it requires a precise sequence of moves, and reassembling it is even more challenging, demanding patience and determination.
