Whadda LED kit brain game

Only 4 LEDs and 4 push buttons offer hours of fun. The aim of the game is to repeat a random pattern. The pattern is played visually, acoustically or visually only (selectable). It has 4 levels of difficulty, which can be selected at start up. The repeat speed gradually increases during the game to make it even more difficult. Energy efficient. Microprocessor-controlled. Auto power-off. Manual update: Some mini kits include a new type of battery holder. Please refer to this new manual update to assemble the new battery holder. This text is machine translated.
