There's more to mobile gaming than decapitating zombies, shooting aliens and driving endlessly round a track.
Sometimes it's good to get the old synapses firing.Keep them fresh, keep them busy, and you'll be sharp when you hit your twilight years.
Or, you know, just play them because they're tonnes of fun.
Here's a selection of some of our favourite Android puzzlers for you to wrap your heads around:
Where's My Water?
Poor old Swampy - a peaceful, chilled-out alligator, he just wants a nice hot shower. Unfortunately the dastardly Cranky has mucked around with the pipes, meaning you'll need to put your grey matter to good use helping the water on its way. That's easier said than done: between each pool of water and Swampy's tub lie all manner of hazards including poisonous acid, algae and bombs. Where's My Water? is a beautifully made puzzler, with endearing characters, plenty of variety and a nicely judged learning curve. It has so far spawned four spin-offs and a sequel, with the Mickey Mouse-starring Where's My Mickey? being our favourite.

Like all the best puzzle games, Threes! is built on brilliantly simple mechanics: in an attempt to clear a 4x4 grid, you merge numbered cards by sliding them into each other, but (with a couple of exceptions) only matched numbers will combine – and when they do, they become a single tile with the combined value of their constituents. OK, so maybe we’ve made it sound more complicated than it really is, but once you’ve tried it, its crack-like addictiveness will grip your heart. The perfect “play for two minutes at a time” game, and its music and visuals are lovely icing on the cake.

The Room Two
The Room Two is of the finest puzzle games our fingers have ever had the pleasure of swiping around. The game throws you into various rooms, many of which have a beautiful Victoria steampunk-esque feel to them. Each one has a series of puzzles ranging from kick-starting old machinery to manipulating levers and secret switches to reveal clues, keys and other items which will ultimately help you escape each section. It's simple in concept, but incredibly tough to crack, and will keep you occupied for a good few solid hours

In Trainyard, the aim is simply to get trains to goal stations of the same colour, by drawing tracks and tapping Start. There’s no time-limit, so you can waste as much time as a typical train operator. But it gets fiendish without you realising; before you know it, you’re merging and splitting trains, routing round rocks, and grappling with a spaghetti heap of track to stop trains colliding.
We fell in love with Monument Valley the second we first stepped foot into its abstract Escher-eque universe. Players are thrust into the shoes of a silent princess who must traverse impossible monuments by dragging and spinning around various features of each level. there's a lot of clever perspective trickery at play, and the level design is absolutely stunning. So much so, in fact, that there's a built-in screenshot feature, which we've used to create some snazzy wallpapers.
