But while this is fun, the controls can sometimes be a little slow to respond, and you can accidentally misfire. On the flip side, there are special bubbles that can help you, as well as uncolored bubbles that can become colorized. Besides having a limited number of shots - well, once you get past the first dozen levels or so - you also have no control over the color of your shooting bubble, though you often have a choice between two colors.

But while this may sound simple, it doesn't stay that way. Do it multiple times, and you'll reach your ultimate goal of clearing all the bubbles - or at least all the bubbles holding owls. Do this, and all the same colored bubbles will pop. By aiming and then launching one of your colored bubbles, you try to hit one of the same color that's next to another that's also of that color - i.e., three in a row. Using simple touch controls, Bubble Witch 3 Saga has you trying to pop all the bubbles on the screen before you run out of shots.

Like playing pool with a ton of balls, this physics-based puzzle game uses simple mechanics to make something compelling and fun.
