Blow Up!

From GameGlade.com:

The aim of the game is to clear the board from the colorful 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 the top. Do not allow balls to fill the playing board till the bottom, otherwise you will loose. There are three playing modes: Arcade, Time Trial and Puzzle. The thermometer indication decreases every time you fail in the Arcade mode so shoot as exactly as possible! You should hurry up in the Time Trial and make the puzzles formed of colorful balls out in the Puzzle mode. There are also a number of bonuses, which can bring you some points, and a lot of fun! The game can be downloaded as well as you can play it online.
