Quantum Flux #4 Level 10

Puzzle Master - Designed by Benno Baasten, the Quantum Flux puzzle series features 3D-printed burr cubes that pack a real challenge. Often called "impossible cubes," these puzzles require focus, patience, and spatial reasoning.

Your goal is to disassemble the puzzle, which is comprised of irregularly shaped, complex pieces and then reassemble them into a perfect cube. If you're careful during disassembly, you’ll pick up clues to help with the rebuild—but rush it, and putting it back together becomes much more difficult.

Made from sturdy 3D-printed plastic and shipped fully assembled, Quantum Flux is a great pick for fans of mechanical design and burr-style puzzles.
