The purpose of the game is to gain as many points as possible. Points are added at the removal of the buttons. The buttons are removed at making a vertical or horizontal combination of three or more buttons of the same color. In order to create a combination like that you must switch two nearby buttons of different color in one round.

This game will come in handy not only at home, but also at the office where you will be able to play in your spare time, and, if necessary, hide it from the eyes of the others.

Besides, if you are in urgent need of doing something else, instead of closing the game you can just hide it behind the limits of the screen. (The game is displayed neither in the tray nor in the taskbar). Then in your free time you can restore the game by mouse-moving at the edge of the screen and press the Ctrl key and continue playing.
