Kumiki Cube Puzzle
This medium-difficulty kumiki-style puzzle involves sliding pieces, aligning notches, and having a firm understanding of the whole interlocking structure to figure out how the pieces all fit together. I designed the pieces to fit tightly and snugly for an enjoyable experience assembling the cube. Sliding the final piece into place even has a satisfying “click!” and the pieces will stay together without any glue or rubber bands.

Lock Cube Puzzle
This bar puzzle is sure to delight and confound even experienced puzzlers. All but one piece has a pair of rods to limit movement, “locking” the bars in place. Assembling it requires not just logic but dexterity as well, to hold all the pieces in place as you construct the cube. Slide the final bar into place and enjoy the finished puzzle.

Admittedly, I’ve never fully solved this one myself or found any solutions online. I can give you a hint, though: start by assembling the pieces in triangles.
