Destroy enemy ships 1, 2, and 3 in order. But... You only see their positions for half a second and have eight times that to destroy them. It's easier than it seems! You only have to touch and then stop touching a hidden enemy ship to destoy it. You can only destroy 2 once you've destroyed 1 and 3 once you've destroyed 2. You'll know you won when it all explodes. Then it will start a new round.
