Use your mouse to aim and throw. You can switch your current bubble with the next one by clicking on the arrows on the left side of the screen. Connect 3 or more bubbles of the same color to pop them. Pop all the bubbles with baby mushrooms inside before you run out of throws.
In later levels, some bubbles have special effects. For example, the bubbles with minus signs inside of them will reduce your remaining number of shots. Try not to pop them!
Move your finger to aim. Release to throw. Pop all the bubbles with baby mushrooms inside before you run out of throws.
