Wire loop game
Appearance
A wire loop game is a game which involves guiding a metal loop along a serpentine length of wire without actually touching the loop to the wire. The loop and wire are connected to a power source in such a way that, if they touch, they form a closed electric circuit. The circuit includes a light- or sound-emitting device of some form, which indicates that the game has been lost.
Virtual versions of this game exist, in which the pointer takes the place of the wire loop and must be guided down a narrow, twisting path without touching the sides. Both versions require well-developed hand-eye coordination. The difficulty of any particular game depends in part on the shape of the twisted wire and the size of the loop.
