You really should stop throwing darts at the balloons, it isn't so effective because there's a high missing chance and you might even hit someone on the eye or worst. Instead of using those dangerous sharp objects, you can use special balloons that pop themselves if they touch two or more with the same color. Don't try to figure out how it works, it's due to a spell and the magician won't tell you his secrets. Basically you can move balloons around vertically or horizontally, as long as every single move makes a successful combination of three or more. They are really cheap, so you won't have the same high prejudice of a jewel combination game, that destroy expensive gems just for fun. Pop as many balloons as you can, not forgetting about the bonus that will help you to blow up the others around, with spikes and temporary darts.
