Marvel at the diverse fauna of our planet while you puzzle your way through vintage-style animal paintings that teach fascinating facts. By playing jigsaw game Art of Fauna you do good along the way – twenty per cent of the game’s proceeds are donated to nature preservation organisations.

What we love: Solving the puzzles from two angles. Art of Fauna lets us decide if we’d rather solve the scientific drawing of the animal or chip away at the words of its educational description. Should we get stuck on either side, we can swap our approach at the tap of a button.

Quick tip: Scared of spiders, bugs or octopuses? There’s a content filter in the settings that hides these and other animals that might trigger feelings of discomfort. You can also simplify the game’s language, fonts and colours to suit your needs.

Meet the creator: Four-time WWDC scholarship winner Klemens Strasser from Austria makes education accessible with Study Snacks and Subwords. Two of his apps – Letter Rooms and Ancient Board Game Collection – have been Apple Design Award finalists.
