I have recently finished an iphone game. This is written in Sparrow framework. I have decided to make it opensource and so put it up on github at this link. The game is very simple and is licensed under Unlicense. So there is no restriction as to how to use the code. You can use it to make money or what so ever as this licensing does not force you to do anything you do not need to do.
About the game, its a simple game of Mathematics for small kids. There are options for addition, subtraction, multiplication and division. Choose your type to play and go ahead playing it. There is no score, no time limit. The responses are immediate. So one will know whether correct or incorrect answer.
While I am developing on it too. Will love to see what others can do with it. This can be seen as code example for the Sparrow framework as well.
