Choose a matrix of buttons from 1 to 9 or a 12-key piano. It will play 2 or 3 tones highlighting the colored buttons. Repeat the pattern by pressing the buttons in the same sequence. If correct, it will play a longer sequence up to a limit of 10 tones. It will keep your best time if you complete the level. For a one-button game, the sequence includes short and long tones.
