38. Galaga 30th Collection

In the old days, invaders from space were strange, remaining in a holding pattern and slowly descending, enabling you to shoot them. By the time of Galaxian, the aliens realised they could swoop down and get you, and Galaga 30th Collection is the game you get here, with minor updates that improve its graphics and pace, albeit for a weighty 140+ MB footprint on your device. Galaga fanatics can unlock other remakes in the series via IAP.

39. X-Baseball

It's a little-known fact that baseball mostly involves trying to hit colourful birds flying overhead and bananas lobbed in your direction by a mischievous fan. But X-Baseball provides a perfect, accurate one-thumb iOS recreation of America's favourite banana-thwacking pastime. (What?)

40. Rogue Runner

Rogue Runner is another one of those endless games, where you leap over gaps and shoot things until you fall down a chasm and ponder why your in-game avatar doesn't learn to stop once in a while. Rogue Runner stands out by offering a ton of skins and a smart overhead dodge-and-shoot variation, which is a bit like Spy Hunter if someone knocked the original arcade cabinet on its side - the vandal.

41. Dumb Ways To Die

Based on a Webby Award winning video, Dumb Ways to Die lets you try and save adorable characters from dying in dumb ways. There's more than a hint of WarioWare when it comes to the game's quickfire levels, which charge you in mere seconds with batting away wasps, saving private parts from underwater peril, stopping a head from exploding in outer space, and many more surreal rescue missions.

42. Chuck's Challenge

Chuck's Challenge is a sweet puzzle game that challenges you to solve a few dozen overhead levels, which are essentially tightly designed logic puzzles. Mooch about, find keys, open doors, and try very hard not to get killed. If your spiky-haired character manages to survive, more level packs are available via IAP.

43. Draw Something Free

"No drawing skills required!," boasts the App Store description for Draw Something Free. You might argue otherwise when this app demands you draw something suitably tricky for your friends to guess, but can merely manage a red blob. Still, Pictionary plus iPhone plus social gaming equals 'must have' in gaming maths.

44. Temple Run

Top tip for any budding Indiana Jones types reading this: do not steal shiny things from temples guarded by demon monkeys, otherwise you will die. Still, if you're too stubborn to take our advice, use Temple Run for training, swiping and tilting your device until your on screen hero meets his inevitable demise.

Temple Run

45. ElectroMaster

We've no idea what's going on in ElectroMaster, beyond a bored girl trying to avoid responsibility by killing everything in sight with electro-blasts. The game's sort of like a twin-stick shooter but you tap-hold to charge and then release to let rip, dragging your finger about to fry your foes.

Games are short, but this is one of the most thrilling blasters on the system, despite it costing nothing at all.

Electromaster

46. Grim Joggers Freestyle

The original Grim Joggers was odd enough: 15 joggers jog for their lives in oddball environments, including a warzone, the Arctic, and an alien world. In the free Grim Joggers Freestyle, you get just one world, but it mashes up everything from the paid game into a surreal (but thoroughly enjoyable) endless survival game.

47. Frisbee Forever

Flinging a plastic disc can be dull in the real world, but in this whimsical game the classic toy gets to soar over desert canyons, through Ferris wheels and alongside pirate ships moored in sandy bays. Frisbee Forever is a flying disc game as Nintendo might have crafted it, with vibrant graphics, jolly music and simple but engaging gameplay.

48. Wind-Up Knight

Kings in fairytale lands have a screw lose, or perhaps just an odd desire to create the conditions for a tough videogame. In Wind-Up Knight, a princess has been kidnapped. Horrors! But rather than send an army, the king tasks a knight with rescuing her. Only he's fragile. And clockwork. And can't turn around.

Really, it's an excuse for puzzle-oriented swipe-based thrills, which demand near-perfect timing as the quest nears its end.

Wind-up Knight

49. Flood-It! 2

Flood-It! 2 meets the rules of great puzzlers: keep things simple, but make the game so challenging that your brains start to dribble out of your ears. In Flood-It!, you tap colours to 'flood' the board from the top-left, aiming to make the entire board one colour using a limited number of taps.

This release offers additional modes over the original Flood-It! (timers, obstacles, finishing with a defined colour), and offers schemes for colour-blind players.

Flood it

50. Greedy Bankers: Bailout!

A nod to our current financial woes, Greedy Bankers: Bailout! is all about greed. You swipe coloured gems together, to make bigger gems; tap and they explode in a shower of gold coins. Avoid the thief and beat the time limit to succeed. Extra modes are available via IAP, but the original—Arcade—should keep dollar signs in your eyes for a long while.

Greedy Bankers

51. Tiny Tower

Social management games are big business, but are often stuffed full of cynical wallet-grabbing mechanics. While Tiny Tower does have the whiff of IAP to speed things along a bit, its tower-building and management remains enjoyable even if you pay nothing at all, and the pixel graphics are lovely.

Tiny Tower

52. Cube Runner

The accelerometers in Apple handhelds have driven development of myriad tilt-based racing games, but tilt controls can be finicky. Cube Runner, however, feels just right as you pilot your craft left and right through cube-littered landscapes, aiming to survive for as long as possible.

Cube Runner

The game doesn't look like much, but it plays well, and longevity is extended by Cube Runner enabling you to create and download new levels.

53. Letris 3

At first, Letris 3 looks like yet another bog-standard word game, albeit one that's rather visually swish, but it regularly tries new things. The game's based around creating words from falling tiles, but it keeps things fresh by adding hazards, such as debris, ice and various creatures lurking in the letter pile. If you're feeling particularly brainy, you can even play in two languages at once.

54. Bejeweled Blitz

Before we played Bejeweled Blitz, we never knew precious gems were so 'explodey'. Still, here's the frantic member of the match-tree/gem-swap family, giving you one minute to obliterate as much shiny as possible, and then discover via online leaderboards that your chums are gem-smashing wizards.

 Bejeweled Blitz

55. Cool Pizza

Cool Pizza isn't so much endless running as endless weirdness. In a world of stark black, white and neon, a skateboarder catches air to hack oddball enemies (laser-spewing mini Cthulhus; rotating pyramids of doom) to death. The crunchy soundtrack adds to the sensory overload, resulting in one of the finest freebies on the platform.

Cool Pizza

56. Frisbee Forever 2

We already covered Frisbee Forever on this list, with its Nintendo-like fling-a-plastic-disc about larks. Frisbee Forever 2's essentially more of the same, but prettier, smoother and with wilder locations in which to fly through hoops and collect stars. It's lovely and costs precisely zero pence, so download it.

Frisbee Forever 2

57. Gridrunner Free

Jeff Minter is a shoot 'em up genius, and his Gridrunner series has a long history, starting out on the VIC-20, at the dawn of home gaming. This update riffs off classic Namco arcade machines but also shoves modern bullet-hell mechanics into a claustrophobic single screen, and in this version's survival mode, you have just one life. Argh! The 69p 'Oxtended Mode' IAP adds the rest of the standard game.

Gridrunner Free

58. Subway Surfers

It looks a lot like Temple Run mashed into a children's cartoon show, but Subway Surfers plays a lot more like Run!, with its primarily linear leaping and sliding action. There are also plenty of power-ups to keep your graffiti-spraying hoodlum away from the chasing lawman and his faithful mutt. Just don't try this at home, kids, unless you want to redecorate a train with your innards.

Subway Surfers

59. HungryMaster

The hero from the insane ElectroMaster returns, but this time she appears to be tasked with feeding sentient houses roaring "HUNGRY!" in a fairly rude manner.

Local monsters amble about, which can be snared by swiping over them with a surprisingly deadly pixie dust trail, whereupon they're handily converted into food to be collected. Much like ElectroMaster, HungryMaster feels like someone found a lost classic arcade game and squirted it into your iPhone, but forgot to charge you for it.

HungryMaster

60. Temple Run 2

We have no sympathy for the heroes of Temple Run 2. Having presumably escaped from the demon monkeys in Temple Run, they steal more ancient and shiny goodies. This time, they're pursued by only one undead ape - but it's massive. Cue: more running/jumping/hopefully not falling over, and some new mine-cart and zip-line sections. Wheeee!
