"Simon Says" Multiple Players

Beyond the classic game's requirement to remember the right color sequence, Hacked Simon Says requires that players also develop their cooperation skills.
The players wear devices which function as the keyboard keys for each color in the game. Each device is separated into two parts: Player A holds the "+" side and Player B the "-" side. When in contact, they close an electric circuit.
By bringing together the corresponding "+" and "-" devices, the players signal the correct color and can apply the color sequence.
