Interlock 4 Wooden Cube Puzzle

A classic design by renowned puzzle inventor Stewart Coffin, the Interlock 4 is a deceptively simple yet deeply engaging wooden brain teaser.

Coffin is widely respected in the world of mechanical puzzles for creating elegant, mathematically inspired designsand this puzzle is a perfect example. What appears to be just four pieces quickly reveals itself as a carefully engineered challenge where order, orientation, and spatial reasoning all matter.

The Challenge

Reassemble the four uniquely shaped pieces into a perfect 333 cube.

These pieces dont just fit togetherthey interlock in a specific sequence, adding an extra layer of depth beyond a typical packing puzzle.
