The set includes a case with a built-in keypad and 10 LEDs (RGB type).
Before the game the operator should set the level of difficulty (from 1 to 9; from the easiest to the most difficult) using the keypad. After that the device turns on (stand-by mode). Players should press the star button (*) to start the game.
The device generates a random sequence of LEDs. Each LED has its own (logically defined) number. Players should repeat the sequence using the keypad. If the repeated combination is correct, a lock will open. Otherwise, players should push the start button (*) again and have another try.
