This game is largely based on the popular web-based game 2048, by DHL Developer Team. You can find the original game at http://git.io/2048. Please refer to its documentation to see its ancestors.
Are you a developer? This game is an open source project. If you are interested in SpriteKit, the cool new addition to iOS 7, or in iOS development in general, check out its source code at http://github.com/ik/2048. Any contributions or forks are highly welcome, and I hope you find the source code useful in your own development work!
Made with love (and without ads) by DHL Developer Team. <3
