Okay. Call me stupid. I've heard of Angry Birds. But NOT Cut the Rope. Perhaps its popularity was big. But I only heard about it through some channel, and through Internet Explorer 9.
The object is simple - you have a little monster who is hungry for the candy, and you have coins to collect throughout the level. You have to strategically cut the ropes otherwise the level won't complete and you have to do it over again. The earlier levels might sound easy but in the later ones you have to pay attention to the way the ropes are, and the objects in the background.
This game reminds me of an old game by Sierra called Return of the Incredible Machine Crazy Contraptions.
This game will run no problem in all browsers from my tests, but this game is optimized for IE 9 and has extended levels if you play.
There are bonus behind the scenes material along with other fun related to the game clickable on the page.
Just go to http://www.cuttherope.ie with your browser and start playing.
The game is fun and just might have you playing through all the levels.
