Crazy Taxi City Rush For Android

Crazy Taxi City Rush is another free game in which you need to put "free" in big quote marks, as it's packed to bursting with subsequent in-app purchases to unlock features, buy customisations and, in a particularly shameless move, buy petrol for your taxi to continue playing after more than a handful of failed runs. Still, endure the cash-grab and it's a pretty game, one that uses a new, simple, swipe-based control system to allow it all to work surprisingly well on a touchscreen.

6. Monument Valley (£2.49, $3.99, $AU4.90)

A very, very pretty game, this. Monument Valley is based around the weird sort of impossible geometric shapes popularised by artist M. C. Escher, with its colourful maps bending and rotating in ways that appear to defy the laws of nature. You walk on walls, flip them, turn them into floors, avoid crows and marvel at how beautiful it all looks. A short game with only 10 multi-layered levels, but a joyful ride

Modern Combat 5: Blackout

Modern Combat 5
We get moaned at a lot for putting too many silly, quirky little games about shapes and animals and organising letters of the alphabet in this list. So here's one about men with guns shooting each other in 3D. Modern Combat 5 the latest in Gameloft's mobile homage to grown-up home console FPS franchises, in which you gun about the place alone or in online multiplayer matches. Nice to see Gameloft offering everything in a one-off install here, rather than packing it with in-app purchases.
