The 36 Cube is an addictive and insanely difficult puzzle. Your goal is to create a level 6x6 cube by strategically placing the thirty-six varied-height colored towers onto the gray base. The catch is that each color must be represented in each column and row. Think of it like a Sudoku puzzle - but in 3D.

This puzzle is so challenging that the instruction booklet reassures you that the puzzle can indeed be solved. Dang.

Ages 8+. Happy puzzling!

The 36 Cube is deemed by its inventor as the "World's Most Challenging Puzzle". When we caught wind of that claim we thought, "Riiiight."

Fast-forward hours later and we're ready to smash it to bits with a sledgehammer. It's a serious mangler of brains. Although we know it's bad for our ego, we continually return to the 36 Cube to try to solve it.

The 36 Cube Puzzle is one of the world's most challenging.

We're glad they wrote that because there have been a few times when we've been skeptical of its solvability. That's probably because we've never successfully solved the 36 Cube. But legend has it that others have...prove your super-smartness and solve the 36 Cube!

Frustrating? Yes. Impossible? No.
