26. Implosion ($9.99/£7.99)
Humans are again getting a kicking at the hands of nasty aliens and it's up to you to stop them. Cliches aside, Implosion offers a stompy slash-and-shoot experience that feels entirely at home on the iPhone but scratches that itch when you fancy playing something that resembles what you'd find on a 'proper' games console.
27. Leo's Fortune (£3.99)
Leo's Fortune finds gruff hairball Leo in search of his gold, which has been dropped in a suspiciously trail-like manner across typically platform-game environments. As he scoops up coins, he finds himself whizzing round Sonic-style loops, solving puzzles by manipulating the environment, and negotiating increasingly complex and deadly pathways. It's a beautiful game, full of character, and well-suited to quick bursts on your iPhone.
28. Letterpress (free)
What mad fool welds Boggle to tug o' war Risk-style land-grabbing? The kind who doesn't want anyone to get any work done again, ever, that's who. Letterpress is, simply, the best word game on the App Store. You make words to win points and temporarily 'lock' letters from your opponent by surrounding them. The result is a tense asynchronous two-player game with plenty of last-move wins and general gnashing of teeth when you realise 'qin' is in fact an acceptable word.
29. Limbo (£3.99)
A boy awakens in hell, and must work his way through a deadly forest. Gruesome deaths and trial and error gradually lead to progress, as he forces his way deeper into the gloom and greater mystery. Originating on the Xbox, Limbo fares surprisingly well on iOS, with smartly designed controls; and its eerie beauty and intriguing environments remain hypnotic.
30. Magnetic Billiards (free)
A game that could have been called Reverse Pool For Show-Offs, Magnetic Billiards lacks pockets. Instead, the aim is to join like-coloured balls that cling together on colliding. Along the way, you get more points for trick shots and 'buzzing' other balls that must otherwise be avoided. 20 diverse tables are provided for free, and many more can be unlocked for $1.99/£1.49.
31. Mikey Hooks ($1.99/£1.49)
If iOS is supposed to be no good for traditional 2D platform games, it's a good job no-one told the developer of Mikey Hooks. The mechanics aren't a million miles away from Nintendo titles starring a certain plumber, but Mikey's also armed with a rope that can attach to hooks dotted about the levels, enabling him to speedily swing to glory. An emphasis on time-attack racing and surprisingly solid controls round out a first-rate title.
32. Monument Valley (£2.99)
In Monument Valley, you journey through delightful Escher-like landscapes, manipulating the very architecture to build impossible paths along which to explore. It's not the most challenging of games (nor one with the most coherent of storylines), but each scene is a gorgeous and mesmerising bite-sized experience that showcases how important great craft is in the best iOS titles.
33. Need For Speed Most Wanted ($4.99/£3.99)
Racing games are all very well, but too many aim for simulation rather than evoking the glorious feeling of speeding along like a maniac. Most Wanted absolutely nails the fun side of arcade racing, and is reminiscent of classic console title OutRun 2 in enabling you to effortlessly drift for miles. Add to that varied city streets on which to best rivals and avoid (or smash) the cops, and you've a tremendous iOS racer.
34. Fallout Shelter (free)
In the run up to Fallout 4, Bethesda has launched Fallout Shelter for iOS, in which you create your very own vault and play the role of the Overseer. Inspired by games like SimCity, FTL and XCOM, Fallout Shelter has a surprising amount of depth to explore as you ensure the happiness of your vault-dwellers, expand your vault, and ensuring its safety from intruders. It's free with in-app purchases, but you'll be glad to know there are no time paywalls.
35. Osmos (£2.29)
This superb arcade puzzler is at times microscopic and at others galactic in nature, as you use the power of physics and time to move your 'mote' about. Some levels in Osmos are primordial soup, the mote propelled by ejecting bits of itself, all the while aiming to absorb everything around it; elsewhere, motes circle sun-like 'Attractors', and your challenge becomes one of understanding the intersecting trajectories of orbital paths.
36. Rayman Fiesta Run (£2.29)
The iOS Rayman games are considered by some to be reductive, overly simplifying console-style platforming to an instant runner with bells on. We instead consider Ubisoft's games distilled: they take the essence of platforming action — running, jumping, timing — and make it truly fit for mobile. Smart, varied level and character design, along with a well-considered unlock mechanism, ensure Rayman Fiesta Run's an iOS classic.
37. Reckless Racing 3 ($2.99/£2.29)
The original Reckless Racing was a superb top-down racer full of character, but the sequel was a hum-drum generic affair. This third title in the series is more like the original, finding tiny cars zooming and drifting about madcap circuits such as a golf course, a mountain village and an abandoned nuclear plant. The physics is a bit floaty, but the game has depth and some amusingly oddball game modes, including a gymkhana.
38. RGB Express ($2.99/£2.29)
RGB Express is seemingly set in some kind of courier's clockwork hell. Little vans must pick up packages and drop them off, colour-matching vehicles, boxes and buildings where appropriate. To complicate matters, roads can be used only once. What follows is a brain-bending game of route finding as you attempt to grow your tiny delivery company.
39. Ridiculous Fishing (£2.29)
If Ridiculous Fishing is what fishing's really like, we've been missing out all these years. An angular fisherman casts his line into the inky gloom, where you cunningly avoid fish by tilting your device. Snag one and the hero reels the line back in, and you jerk your iPhone from side to side, aiming to catch as many fish as possible. At the surface, the catch is flung into the sky, to be blasted to pieces by powerful weaponry. Longevity's secured by an amusing in-game store and social network parody, along with several fishing spots to visit.
40. SpellTower ($1.99/£1.49)
SpellTower is a fantastic word game that starts off easy. You get a grid of letters and remove them by dragging out words. Your only foe is gravity, letters falling into empty space as completed words disappear. But then come new modes, with ferocious timers and numbered letters that won't vanish unless you craft long enough words. And there always seem to be too many Vs!
41. Super Hexagon (£2.29)
Ah, Super Hexagon. We remember that punishing first game, which must have lasted all of three seconds. Much like the next — and the next. But then we recognised patterns in the walls that closed in on our tiny ship, and learned to react and dodge. Then you threw increasingly tough difficulty levels at us, and we've been smitten ever since.
42. Super Monsters Ate My Condo (free)
Logic? Pah! Sanity? Pfft! We care not for such things, yells Super Monsters Ate My Condo. It then gets on with turning the match-three genre and Jenga-style tower-building into a relentless time-attack cartoon fest of apartment-munching, explosions, giant tantrums and opera. No, really.
43. Super Stickman Golf 2 (free)
If you've often thought golf would be much better if it was played on Mars, or in a giant castle, or in dank caverns with glue-like surfaces, Super Stickman Golf 2 is the game for you. Its side-on charms echo Angry Birds in its artillery core, but this is a far smarter and more polished game. It also boasts two equally brilliant but different multiplayer modes: one-on-one asynchronous play and frantic multiplayer racing.
44. Superbrothers: Sword and Sworcery EP (£3.99)
Apple's mobile platform has become an unlikely home for traditional point-and-click adventures. Sword & Sworcery has long been a favourite, with its sense of mystery, palpable atmosphere, gorgeous pixel art and evocative soundtrack. Exploratory in nature, this is a true /adventure/ in the real sense of the word, and it's absolutely not to be missed.
45. Threes! ($1.99/£1.49)
Threes! is all about matching numbered cards. 1s and 2s merge to make 3s, and then pairs of identical cards can subsequently be merged, doubling their face value. With each swipe, a new card enters the tiny grid, forcing you to carefully manage your growing collection, and think many moves ahead. The ingenious mix of risk and reward makes it hugely frustrating when you're a fraction from an elusive 1536 card, but so addictive you'll immediately want another go.
46. TouchTone ($2.99/£2.29)
There are two sides to TouchTone. The foundation is a topical story about intercepting communications, ostensibly to make the world safer. The game itself involves reflecting signals to receivers, using a tiled grid where every item on a row or column moves as one. The story gives you added impetus to keep going, even when you've been racking your brains for days to come up with a solution to a particular puzzle.
47. Traps n' Gemstones ($4.99/£3.99)
There's some superb level design in this touchscreen take on Metroid, with you helping a tiny explorer bound about a pyramid. There are gems to collect, critters to kill and secret areas to unlock via the magic of cunning object placement. Equally cunning is the scoring mechanism – it resets on every death, unlike progress, which always continues. This means casual gamers can gradually work through the quest while the hardcore aim to get every gem in a single sitting.
48. Walking Dead (free)
We do like a good zombie yarn, as long as we're not the subject matter, having just had our brains eaten. Walking Dead successfully jumped from comic to TV screen, and it's just as good in its interactive incarnation. The first part of the story is free, and you can then buy new episodes; if you survive, season 2 is also available.
49. Year Walk (£2.99)
Year Walk preceded the same developer's iOS masterpiece Device 6, but is equally daring. It's a first-person adventure of sorts, with more than a nod towards horror literature and, frankly, the just plain weird. It's unsettling, clever, distinctive and beautifully crafted — another unmissable and original touchscreen creation.
50. Zen Bound 2 (£2.29)
One of the most tactile puzzlers around, Zen Bound 2 doesn't sound terribly exciting, in that you're wrapping sculptures in rope. But the atmosphere and polish combine with a nagging percentage bar, urging you to perfect each level. With no time limit, it's one of the more soothing puzzlers in this round-up, but it also never drifts towards the noodle.
