Overview
Cut the Rope is a physics-based puzzle video game developed by ZeptoLab and published by Chillingo for iOS, Android, Windows Phone, web browsers, Nintendo DSi, and Nintendo 3DS.
Gameplay
On each stage, a candy is hung by one or several ropes, which the player can cut. The goal of each stage is to get the candy to a green monster named Om Nom by cutting the ropes in a particular order while utilizing the game's physics to get the candy to Om Nom. As the game progresses, new elements are added to the puzzles; examples including bubbles that can float the candy offscreen and spiders that can steal the candy. Such elements require the player to utilize them in such a fashion that the candy can reach Om Nom.
There are several levels in the game, each divided into 25 stages. Each stage has three stars that can be collected by having the candy touch them. Though the stages can be completed without collecting all three stars, the stars are necessary for unlocking later levels.
