There are four different colour bubbles (red, green,
blue, and yellow) and bombs (black) in each game.
The amount for each colour bubbles or bombs are stochastic.
When you click two or more same color bubbles together,
they will be disappeared with comic music, and you
get scores. You can't clear away the single bubble
by clicking it. (It also will make comic music to
remind you)
Here
you get useful help from bombs. They will help
you to clear away the bubbles attaching them.
View following pictures to know how bombs work
for you.
When you clear away all the bubbles, you Win, and
you can continue the next game.
