The objective of this game is to identify the sounds contained in the audio cassettes as they're played, in order to get rid of your "note tokens" (DO, RE and MI, each representing different difficulty levels). When you think you know what sound is played, press your button in the electronic device and give your answer. If you're right, you can get rid of the correspondent token. If you fail, you have to take another token. The first to get rid of them all, wins the game.
