Simply tap the vortex to make it evolve. It has a fast evolution (within one minute if you are quick) and a slow evolution (actually slow, but changes the vortex very much to the end).
This game is addictive, so be careful.
It is a good antistress game. For relaxation.
There are surprises in the end.
