Test your reaction timing by either pressing the button at the bottom left momentarily when all LEDS are OFF, or hold the button down and release when all LEDS are OFF. If the LEDs stop chasing and green LED stays on, you win! Otherwise the LEDS will keep chasing so you can keep trying. Press the button again momentarily to reset the game.
You can control difficulty (speed of LED chase rate) by adjusting the simulator clock.
