|Airport Mania: First Flight|
By Lemon Team - buy on iPhone or on iPad
It's admittedly not the best aviation-themed casual game on the App Store, but this overlooked time-management game will still suck up your time and expel it like so many bloodstained feathers.
By Jonathan Huer - buy on iPhone
This unusual FMV game with branching storylines and various conclusions is fairly short on interactivity but fairly long on fun and novelty.
By Ancient Workshop - buy on iPhone or on iPad
Help a paralysed frog to eat a fly by sliding its feet up a leaf. More fun than it sounds.
By Bit Blot - buy on iPad
Largely non-violent underwater Metroidvania that's a sensory treat to explore, even if the controls let it down during combat.
By Rake In Grass - buy on iPhone and iPad
Inventive platformer featuring plenty of challenging environmental puzzles, solid controls, and the underused word 'Archibald'.
By Niklas Wahrman - buy on iPhone
You're in a spaceship, but you get around by swinging on a rope. Games don't have to make sense.

Top-down shooter in which you don't shoot. Like a full-game version of the Pacifism mode from Geometry Wars: Retro Evolved.
By Wade McGillis - buy on iPhone and iPad

By Qwiboo - buy on iPhone and iPad
Trials HD isn't available on iOS. This extremely playable dirt bike game is the next best thing.
By Zach Gage - buy on iPhone and iPad
Bit Pilot involves tracing your finger around the screen to avoid asteroids until you die. It's simple, elegant, playable, and 100 percent futile.
By Jean-Philippe Sarda - buy on iPhone and iPad
There's no shortage of iOS apps in which you can move coloured blocks around, but few can match Blockoban's preposterously abundant 4,050 stages.

By Cascadia Games - buy on iPhone and iPad
Oh, look: more pixel-art. Cascadia's puzzle-platformerCavorite isn't perfect, but it's nicely presented and contains clever puzzles that you won't find elsewhere.
By Hicham Allaoui - download on iPhone
In essence, this brutal fast-paced platformer is a moderately plagiaristic vegetarian alternative to Super Meat Boy.
By Wet Nose Design - buy on iPhone
Yet another unique and starkly presented touchscreen puzzler. The gameplay is undeniably innovative, but even if it weren't the utterly brilliant music makes it worth playing alone.
By Vishindo - buy on iPhone an iPad
Collision Effect is a game about Zybbles, orbs, and arcane rules of interaction. It's far harder to explain than it is to play.

You don't see many accelerometer-based ball-rolling games these days. That's probably because nobody can improve onDark Nebula - Episode Two.
By Denki - buy on iPhone or buy on iPad
Denki Blocks! is hardly unknown, but it's worth a place on this list if only to remind ourselves that not all puzzlers involve matching three things.
It goes without saying that there are bound to be literally trillions of other games that could have qualified for this list.
It would be immensely useful if you could point out how thick we are for omitting them by sharing your suggestions in the comments section below.
