Keep or Skip is a game with no GUI.
During the game, youll listen to a short clip of a randomly selected track from your iTunes library. The clip is divided into pieces which are mixed up.
The games aim is to reconstruct the correct musical sequence.
Before listening to a clip, you can choose to skip one track. You cant skip more than four tracks in one game. If you make five mistakes selecting the sequences, the game is over and you lose.
You can play to beat your personal high score and you can also send your score to the world-wide database from the game. You can also listen to the world-wide top ten from the game.
When the voice asks you to select a command, you can type the first letter of the command on the keyboard or, if you have a compatible microphone, say the command using the Mac OS X built-in Speech Recognition system. In this case you have to press the "esc" key, or the key you selected in the system preferences, before saying the command.
Main features:
Rich use of Apple technologies:
