Game Description & Manual: When it is your turn, click on a bubble to inflate it a bit. When a bubble is pumped up to the maximum, it will pop, changing the color of the 4 surrounding bubbles: left, right, above and below. And the value of each of the 4 surrounding bubbles will be increased by one.
Tip1: if you click on a bubble with a value of 4, it will pop. But bubbles along the edge of the board will pop after only 3 because they only have 3 neighboring bubbles. A corner bubble will already pop after 2, because it has only 2 neighbors.
Tip 2: if you can create popping chain reactions, you will get a lot more points than popping only 1 or 2 bubbles at a time.
