Max and the Magic Marker

Channelling the ghosts of Battlezone, Robotron and Geometry Wars, PewPew is a gorgeously retro slab of wire-frame shoot-'em-up insanity. Through a series of stark environments, you blast at incoming enemy craft using a virtual twin-stick setup. The action is fast and frantic, the screen regularly teeming with shards of neon shrapnel, and there are four stages to scorch through, including Mega Gore, in which you simply blast everything that moves, and Dodge This, where your weapons are taken and you simply have to navigate through the carnage. It's exciting, bewildering and tinged with vintage visual design sensibilities. And there's a fantastic sequel out already.

Two huge global mainframe send their robots to destroy each other, and you need to win the good computer by the turn-based one-on-one help to android war. Manage two or more symbols of the same and your attack is stronger: In a new twist, are actions that chosen by a slot machine mechanic, which rotates through the available options per turn. It 'sa good idea, expertly executed and with a nice visual flourishes. "Known Slot machines aren 't for her strategy credentials," admits Hearn. "But somehow Robotek makes a large part luck-based effort in an engaging and stylish casual freemium strategy game. How Peggle and countless other casual hits, it 's this balance between luck and skill that makes Robotek extremely accessible. And it 's free \ \. "

Sonic & Sega All-Stars Racing

Sumo Digital's faithful port of the very good Mario Kart-style console racer is a required purchase for Sega nuts. With fun handling and a range of courses designed around classic titles such as House of the Dead and Samba De Amigo, it's an assured cartoon drive-'em-up. We also love the choice of drivers behind the wheels of the various vehicles (which boast appreciably diverse handling characteristics) – who wouldn 't want to jump into a car with the stars of Shenmue or Jet Set Radio? As Hearn enthuses, "Online and local multiplayer, challenges, a thrilling sense of speed and some deft handling make this the closest the iOS has ever had to a proper Mario Kart rival, and far better than we've come to expect from home console ports."

Back in 2008, World of Goo was one of the original stars of the indie revival, revered alongside the likes of Braid and Darwinia as a beacon of hope for the bedroom coding fraternity. The iPhone version retains the original WiiWare title's central premise – you must traverse a series of obstacle-filled screens by building bridges and towers out of blobs of goo. There are various types of globules, each with different capabilities, and the deceptive depth and calming properties of this physics-based challenge is almost zen-like. The touchscreen controls also work brilliantly, adding a pleasingly tactile element to the action. An absolute must.
