Hyspherical 2
Hyspherical 2 is a tricky puzzle game where you must time dropping circles onto different shapes. Sounds easy, but timing is everything.
Get a circle to make a single loop around each shape without hitting another circle. You have to complete a full rotation of each shape in order to proceed to the next level.
The complexity comes as the shapes begin to move, spikes begin to appear and timers start to count down.
Free on iOS.
