Original puzzle created by the famous inventor Wil Strijbos. Separate the two parts of the cross. It requires no physical force or pounding and there are no magnets. A brainteaser of high quality and extremely difficult to solve!
This puzzle is an ongoing adaptation of the inventor, who created his first wooden padlock in 1979. The evolving mechanism, compartments and passages made this puzzle very difficult. Unlike the First Cross, there are several procedures and marbles inside. A real challenge for puzzle lovers!
This new lock is made of gray anodized aluminum, highly resistant to tampering (like the professional rifles of mountaineers) and robust. A high-quality product made of precision machine-polished aluminum and has Wil’s signature and the name of the puzzle engraved on it. A true masterpiece in the world of sequential puzzles!
