The object of Switcheroo Deluxe is to click on sets of the same color in numbers of 2 or more to clear sections of the game screen. You can advance levels by clicking on "Level Up" at the top of the window if your points match or exceed those pre-determined to qualify for the next difficulty level. If you get stuck you can select "Reset" from the file menu which will scatter the olored boxes in another order so as to make more moves possible.
