You are going to play a short game, your aim is to get the highest score.
You will be shown a balloon that you can fill up with air using a pump. For each pump you will get points. If the balloon fills up too much, it explodes and you lose all the points accumulated in that balloon. You can stop pumping air into the balloon whenever you want, "cashing in" the points accumulated in that balloon to your total score.
Each balloon is different and might explode after a different number of pumps. You will have 10 rounds in total.
The "Inflate balloon" button will pump air into the balloon, and the "collect" button will collect the points you have accumulated and move on to a new balloon.
