Wire loop game

A wire loop game, or buzz wire, is a game which involves guiding a metal loop (a 'probe') along a serpentine length of wire without 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 is connected to a light or sound-emitting device of some sort, so that when the loop and the wire touch, the light-emitting device will light up, and the sound-emitting device will make a sound, traditionally a buzzing noise. In commercial implementations of the game the wire is usually bent along a single axis.

This game is also called a steady-hand game or an electronic loop game.
