This is a basic game based on Red Light, Green Light. Essentially, you tap on the yellow signs when the light is green to rack up points. If you tap on a yellow sign when the light is red, you lose. Seems easy enough, right? Try it yourself!

NOTE:
A sign may appear in the same position more than one time. The idea is to keep tapping on it continuously until the next sign appears on screen. You will notice the counter increases with every tap, even when a sign is in the same position.
