Hundreds, you should be a really easy game, you know? Tapping on circles to make them grow, increasing their value so everything adds up to 100. Making sure red active circles don't collide. Easy idea, easy to play, but when it comes down to actually getting somewhere, you present quite the little challenge. Part puzzle but bigger part arcade game, Hundreds from Semi Secret Software (which includes Adam Saltzman, creator of Canabalt) and Greg Wohlwend (from Solipskier team Mikengreg) is a minimalist experience that nabs your interest from the first level and refuses to let go until you've driven yourself mad with numbers and circles.

The title says it all: Canabalt HD is Canabalt in HD! The epically popular one button running game that originally appeared in browsers back in 2009 has made its way to the mobile scene before. There's even C64anabalt for the Commodore 64! Now, with bigger, more powerful mobile devices around, this high-definition version of the game comes along, featuring remade 3D backgrounds and smoother animation. Don't worry, though. It's still just as easy to leap out a window and smack into another building!

The mystery of the ages has been solved! Today we can get a robot to move up a vertical plane using his grappling hook to attach to floating spheres! And it is terribly addictive too... How high can you go? The original game was fun, but hellish in its expectations and difficulty. Gravity Hook HD is MUCH easier to play. It is also prettier, has a better soundtrack and no doubt hides other gameplay enhancements.

Adam Atomic's "minimalist" action/arcade side-scrolling game about a man fleeing the destruction of his city is both remarkably well presented, and fiendishly addictive. Vault over the obstacles in your path as you try to stay alive and get the high score. Those giant robots rampaging in the background? They're not there to play patty-cake, so we'd keep moving, if we were you.

Put Paper Mario and Tim Burton in a blender and you get Paper Moon, a smooth, sophisticated example of how to integrate design and mechanics into a masterful casual game. It's a platformer with a twist, and with enough style and depth to keep you coming back for more.

Simplicity reminiscent of an Orisinal game but with visuals and sound you might expect to find in something more old-school. Backed by an enjoyable physics engine and a simple but well-executed concept and virtually no down-time, Gravity Hook is a simple, grappling hook arcade game that borders on clinically addictive.
