Just 4 LEDs and 4 push buttons provide hours of fun. The aim-of-the-game is to repeat a pattern, which is generated randomly. The pattern can be played both visually and audibly or visually only (selectable). It features 4 difficulty levels, which can be selected at start-up. The replay speed slowly increases during the game, to make it even more challenging. Low power consumption. Microprocessor controlled. Auto power off.
