Cut the Rope: Experiments and Cut the Rope: Time Travel.
Cut the Rope is a single-player physics-based puzzle series where players must devise the best way to make a piece of candy fall into an adorable little monster's mouth. Basically, it's a game about healthy eating habits, as written by small children. According to an announcement press release, Triple Treat features over 650 levels, in-game achievements and leaderboards.
Since first arriving on the competitive mobile scene, Cut the Rope has struck big with players, surpassing 3 million downloads soon after its 2010 launch. Originally published by the EA-owned Chillingo, Cut the Rope's expansions and sequel were subsequently self-published by ZeptoLabs.
