This is the “Skeet” Shooting Game Project from Jaycar. The kit checks your hand and eye coordination. There are 9 green and 1 red LED. There are two switches: one is reset switch and the other is FIRE switch.

After you connect the 9V battery, the LEDs start scrolling and you have to hit FIRE switch to stop the scrolling at RED LED. The kit is based on CD4093 and CD4017 chips. It takes about half an hour to build the kit.
