Roman Arches Puzzle

Two linked metal arches form a disentanglement puzzle. Explore their curves and openings to find the sequence that separates the pieces and brings them together again.

The disentanglement puzzle challenges you to separate and reconnect two linked pieces. The maker specifies ages 14+; we have not independently rated its difficulty.
