This set of three contains Labyrinth Cubes: Some, Diabolical, and Plus 4. Each puzzle is made of pieces that all have a number of tunnels passing through them. The goal for each one is to use the pieces to create a 3x3x3 cube such that you create a single tunnel that passes through all 27 voxels. Once this is accomplished you then put the top on and twist, flip and turn to navigate the marble from start to finish.
Size of each: 2.5 in x 2.5 in x 2.5 in
Small pieces (ball bearing); not intended for small children.
Shipping costs to be determined based on the buyer's address. (It should be around $15 for US and higher for international).
Feel free to post a question with your zipcode for the actual shipping cost.
