Click the board to randomize the setup. 49 balloons will drop.
The balloons have directional markers which indicate which of its neighbours (not necessarily adjacent) will pop when you click it. The clicked balloon will also pop.
You can only click balloons which will cause at least one other balloon to pop.

After your move, all remaining balloons will rise up as far as possible.
There will also appear a new balloon after every move.

You win when you have popped all balloons.

Variant 20-28: random setup (100 Balloons). Variants have increasing difficulty (because the balloons are less and less destructive).
Variants 29-34: two new balloons appear after each move.
