Memory Master will play a random light and tone that you must repeat by clicking on the correct buttons. The sequence of lights and tones will continue to grow unless you fail to master it.
If you miss a sequence press "Replay". The sequence will then be replayed. Use this feature sparingly, each game has only 3 available replays.
Note: 1.0 is the version number of the free version; the commercial version is at 1.01.
