If you're a sucker for physics-based puzzlers as I've always been but really can't stand Angry Birds anymore, Cut the Rope is a much-needed refreshment from Rovio's bird-slinging franchise. On the surface, the concept seems dull: you're tasked with feeding candy to a little green monster named Om Nom while collecting stars.

But it's how developers executed the super-realistic physics gameplay and paired it with colorful cartoonish visuals that blows mind.

Tens of millions of players can't be wrong and I'm also guilty of falling in love and getting addicted to Cut the Rope. Already downloaded more than 300 million times around the world, the game's never been free on the App Store so it's kinda big deal  that Apple's just made Cut the Rope its Free App of the Week...

Boy, I've spent countless hours and had tons of fun playing the Sky Gamblers games by Atypical Games. It's one of those system sellers that every avid gamer should have on their device to show off to friends, it's that good.

In terms of graphics, these games literally have it all: lots of detail, interactive cockpits, special effects galore, specular masks, bump mapping, atmospheric scattering, volumetric clouds with realistic lighting and sun glare.

There are also beautiful day and night transitions, God rays, high definition textures, 4x anisotropic filtering, high dynamic range rendering, radial blur, heat haze, refractive raindrops and lots more. The care and thought that had gone into designing Sky Gamblers: Storm Raiders, the most recent installment, has clearly caught Apple's attention.

Previously, the iPhone maker featured Sky Gamblers: Storm Raiders as one of its 2013 Design Award winners and now the company has decided to feature the game as its Free App of the Week. Trust me, Storm Raiders is the ultimate World War II air combat game and you'd be foolish to pass on it..
