Baguenaudier

Baguenaudier (also known as the Chinese Rings, Cardan's Suspension, Cardano's Rings, Devil's needle or five pillars puzzle) is a disentanglement puzzle featuring a loop which must be disentangled from a sequence of rings on interlinked pillars. The loop can be either string or a rigid structure. Variations of this include The Devil's Staircase, Devil's Halo and the Impossible Staircase. Another similar puzzle is the Giant's Causeway which uses a separate pillar with an embedded ring.
