Spiky Circle is a challenging skill game in which you have to keep an eye out for the spikes that pop up anywhere within the circle. There's a Smiley Face bouncing around through the circle, and it mustn't land on the spikes. Turn the circle left and right to rotate the spikes and slide them out of the way. Every time your Smiley bounces, the spikes will retract and pop up somewhere else, so you will have to stay alert. Collect the yellow diamonds while you play.
