67 – Mystery Set

Are you ready to unravel secrets and conquer complex challenges? The 67 – Mystery Set is a premium trio of handcrafted mechanical puzzles designed for seasoned puzzlers who crave a serious mental workout.

Inside, you’ll find three masterpieces of design and precision:

The 250-Move Schloss Puzzle Lock
A marvel of German engineering, this sequential puzzle lock demands 250 precise moves to open. Manipulate the four metal pins in the correct sequence and reveal the secret—without a key.

The Japanese Diamond Puzzle
Deceptively elegant, this diamond-shaped puzzle hides twelve interlocking pieces that must be carefully disassembled and reassembled. Find the single “key” piece that unlocks its geometric secret.

The Nutcase Puzzle
Designed by the legendary Oskar van Deventer, this ingenious metal puzzle challenges you to free the trapped nut and, for an extra twist, reassemble it to spell “Case Nut.”

The 67 – Mystery Set is for those who think deeply, solve patiently, and love the thrill of the impossible.
