At the start of the game, there are 140 balloons. Your job is to pop as many of them as you can, but you can only pop the balloons when there are two or more of the same color underneath or next to each other. Don't be too hasty, though. First you need to figure out which balloons you have to pop first so that you can pop them all!
You pop the balloons by clicking on them. When you pop one or more balloons, those underneath will float upwards.
Bonus spin:
Some of the balloons are filled with water. When they are popped, the lake fills with water little by little. When the lake is filled, and the water is flowing through the river, the mill begins to produce enough electricity to start the bonus spin.
Bonus level:
If you have five balloons or less at the end of the game you obtain a bonus level. Here you have the opportunity to earn lots of tokens.
