This difficult 6 piece interlocking cube puzzle was 3D printed in strong, white nylon and then each piece has been hand-dyed and individually worked to ensure a smooth action. Assembling and disassembling this puzzle requires a precise sequence of 14 movements including sliding moves and rotations. The finished cube is 3.2 cm across.
Start with the closed loop and try inserting the H-shaped crossbar into it. Not as easy as you might think, but there is a clue in the name. Make sure you get it the right way round and then the other four pieces should fit in to make a 4x4x4 cube. Watch out for a couple of sneaky rotations too.
Using the name of the puzzle as inspiration, and the obvious link to a circus, I coloured alternating pieces red and yellow in the order that the cube is assembled and disassembled. Just another little clue to help you solve this fiendish puzzle.
This is my newest and most difficult design and probably the one I am most proud of. Jos Bergmans called it "Very, very good, a total delight."
