Cut the Rope 2 was released on 19 December 2013 for iOS devices. It expands on the previous games with Om Nom no longer being a static stage object, additional creature characters and a more dynamic environment.[11] The Android version was released on March 28, 2014, on Google Play[12] and on April 3 on Amazon AppStore.[13] Unlike the iOS version, Cut the Rope 2 for Android adds free-to-play elements such as an energy system, and features a map like structure instead of level packs; these features would eventually be added to the iOS version of the game.
