About this product
A battery-powered quiz board where the player links each question to its answer using two alligator-clip probes. When the correct pair is touched, the circuit closes and the green LED lights up. Built on a breadboard with a 9V battery connector, it teaches closed circuits and hidden wiring, and needs no controller, computer or soldering.

Frequently asked questions
Which battery does it use?
A 9V battery, such as the 6F22 type listed in the kit contents, connected to the breadboard through a 9V battery connector.
Why does the green LED light only for the correct answer?
Each question is wired behind the board to its correct answer, so only the right pair closes the circuit when touched.
