The K Puzzle is a perfect choice for people looking for a less difficult, low stakes puzzle that will not take as much time to solve. The box comes with 5 non-identical wooden pieces that can be configured to form the letter “K” - if you can find the solution! The K Puzzle is great for children to learn basic geometry skills, and to start developing their spatial reasoning skills at a young age. All of the pieces come with a sturdy wooden box to contain and store the puzzle. Although it works great as a children’s gift, the K puzzle can be enjoyed by all ages and skill levels.
