Quell+ (iOS) – FREE
Quell is an enchanting puzzle game of logic and relaxation. The game-play is simple: slide a little water droplet around a window-pane, avoid the spikes and collect the pearls. Easy, right? Absolutely, but the beauty of Quell is in the perfectly pitched difficulty curve – it’s just taxing enough to test your powers of logic, but never so much so that it stops being fun.
