Cut the Rope
Om Nom, ZeptoLab's cuddly little green monster, makes the leap from your iPhone to your browser via sleek HTML5 in the physics puzzle game Cut the Rope. A knock at your door delivers the tiny green dude in a box, along with the instructions to feed him with candy, so that's exactly what you're going to do! Click and drag across the screen to cut through ropes and drop the tasty treats down Om Nom's gullet. As it falls, the candy can grab you the three bonus stars scattered around the level... provided you weren't just slicing willy-nilly and can master the various obstacles and elements that are introduced as you play.
Cut the Rope makes the transition to your browser more or less gracefully, and is a beautiful showcase of just what HTML5 can really do. While there are only a few sets of levels available to play unless you want to boot up Internet Explorer and install the game (for free) to your toolbar, it's still a great way to get a taste of what the game has to offer. It's a simple concept with a lovely presentation that's the perfect treat to indulge in for a few minutes.
