The game lets you pump up 15 balloons. Each pump gets you 5$. The goal is to collect as much virtual $ as possible from pumping up the balloons. However, be aware that even starting from the first pump balloons can pop and you lose the whole money from this balloon when you did not collect it.

Can you be #1 in the worldwide high score?
