300 Move Void Lock Puzzle - Brain Teaser Puzzle Lock
The Voidlock is a nefariously deceptive lock puzzle that requires no regular, run-of-the-mill key to open, only the supplies in your own brain! The objective is to find the proper sequence of 300 moves by sliding the metal pin in either direction. Once the puzzler finds the right pattern, the padlock comes free and the puzzle is complete! The Voidlock is co-branded with German puzzle designer Jean Claude Constantin and Kubiya Games.
