A memory trraining game with 4 LED buttons can be built from this set. The player must memorize an ever-expanding series of colors and then imitate them exactly. If the player reproduces the sequence correctly, the game advances to the next level and the device plays a longer sequence. If the player makes a mistake, he is out of the game.
After starting the game with the Start button, an LED button lights up, which the player must press. After that, two LED buttons flash one after the other, which the player must also imitate. The series of flashing LEDs will become longer and longer, making the game more difficult. Up to 99 LED levels are available.
