Quick Draw

The goal of Quick Draw is to test your reaction time against your opponent’s.

A third person acts as a referee and begins the duel by pressing S1, which lights LED1. Upon seeing LED1 go on, you try to outdraw your opponent by moving S2 from “Holster” position to “Draw” position before your opponent moves S3 from “Holster” to “Draw” position. Who ever gets there first will light the corresponding LED and will automatically prevent the other LED from lighting, clearly indicating a winner.
