As well as being perhaps the most painful chapter in the Karma Sutra, Rotating Balls is actually a pretty super little brain-teaser that’ll provide you with at least a few minutes of blinding rage.

Like Frustration, but less frustrating, Rotating Balls asks you to navigate your way around a maze with a mouse. However, Rotating Balls‘ USP is that you have to control two balls that, yes, constantly rotate. That means that the narrower parts of the maze have to be dealt with quickly, cleanly and efficiently before the balls rotate round more and smack against the sides. We’ve explained Rotating Balls to you terribly – maybe it’s best if you just play it for yourself.
