9. Plague Inc (free)

Plague Inc

A really enjoyable and tough strategy game, in which you play some sort of evil god intent on crushing all of mankind. You do this by developing viruses, which spread through the air, water or human contact, gradually wiping out countries, continents and, if the wind's literally blowing in the right direction, everyone.

10. Whale Trail Frenzy (free)

Whale Trail Frenzy

No one dies of disease in Whale Trail. It's a sweet flying sim, which sees you float about in the clouds having a lovely time, collecting things, boosting and generally being quite happy about it. The cheery vibe is broken a bit when adverts and in-app purchase requests pop up, but it's happy enough before the money men turn up.

11. Pitfall! (free)

Pitfall!

We had low expectations of Activision's odd decision to rework its ancient platform game as an endless runner, but it turned out surprisingly nice. Key to its winning nature comes from the variety of the levels, which sees the adventuring hero endlessly minecarting, endlessly motorbiking and endlessly whipping, in a thoroughly enjoyable little game.

12. Bad Piggies (free)

Bad Piggies

Angry Birds maker Rovio proves it's not a one-trick bird-pony with this, a bizarre and quirky physics game. You have a toolbox at your disposal, used to build a flying and/or driving machine, which then has to trundle its way through a level. It's silly, but at least attempts to shove out some new ideas.

13. Pocket Planes (free)

Pocket Planes

An extremely clever and enjoyable miniature strategy game that has you taking control of a small airline and attempting to ramp up customer numbers. It starts out with a few simple freight runs before you expand the fleet, open up new routes and generally get a bit panicked about how many people are depending on you for their holidays.

14. Radiant Defense (free)

Radiant Defense

The tower defense genre is heaving on Android, thanks to the poke and press play mechanics being ideally suited to touchscreen play. Radiant Defense is a great example of the simplified strategy concept, presenting its war action in a futuristic neon style that looks awesome on any phone with the grunt to do it justice.

15. Pocket League Story 2 (free)

Pocket League Story 2

Kariosoft's made a big thing for itself by using its management style of game across various scenarios, with this sporting event being one of the best. You take control of a club, then stress about signings, money, tactics and more. It's slightly robbed of some fun via a desire to use in-app purchases to squeeze money out of players, ironically mirroring the state of the game it takes inspiration from.

16. New Star Soccer (free)

A great football management game that has a bit of a sense of humour about itself. There's some turn-based play, but it's more about bringing together the off-pitch lifestyles of players with the crucial money matters of the football universe. Like Pocket League Story there are some in-app cash demands, so prepare to be badgered for payments after you've progressed some way through.

Tiny Death Star, Sonic Dash, Cut The Rope Time Travel

17. Star Wars: Tiny Death Star (free)

An absolutely gorgeous pixel-art recreation of the Star Wars universe, in which players embrace the dark side and go to work creating Death Stars to please the man in black. A massive challenge, made even more massive should you choose to play it without resorting to taking the shortcut of paying real money for in-game cash.

18. Sonic Dash (free)

There is some arguing as to whether this is "free" as it's rammed with in-app purchases, but there's no dispute as to its quality. Sonic's latest mobile game is, appropriately, an endless runner, with the hedgehog jumping left and right to avoid obstacles placed around its familiar green worlds.

19. Cut the Rope: Time Travel (free)

The weird little physics game is one of Android's most popular franchises, with this update introducing a few new tricks and weapons. It's the same sort of experience as its earlier chapters, though, with players swinging ropes to throw sweeties around its colourful screens. Masses of levels and a mid-to-high fun level.

20. QuizUp (free)

QuizUp is a staggeringly clever online pub quiz app, where you play with random strangers or friends. You can pick from a massive amount of categories, from riddles to sports through to Adventure Time, so you won't be caught out by subjects you don't know. Its simple quiz rounds only take a couple of minutes to get through, plus there's a seamless offline challenge option so you can mentally battle people who then take their turn later. It's loaded with questions and constantly updated with new categories. A real treat.
