The aim of the game is to clear the board from the coloful balls. You can shoot with the ball that appears at the bottom of the board. Having aimed with the mouse cursor to the wanted place, click left mouse button and the ball will fly. Collect 3 or more balls of the same color and they will burst up!
There is a thermometer under the playing board. When it shows " Hot" one more row of balls adds on top. Do not allow balls to fill the playing board till the bottom otherwise you will loose.
