Hi,

I am trying to find a books or resources that provide short pieces of code for a variety of different 2D game types.

Examples of how to set up a grid; and control, move, calculate win conditions for any game pieces etc..

or specific examples of making a:

1. Tetris style game
2. Bejweled style game
3. Chess style game
4. Puzzle style game
5. Etc..

Hopefully you get the picture of what I am after, I don't won't full copies of a game, just pieces to explain how the did the calculation for various parts.

If there are any Unity specific, great. Otherwise just JavaScript would be just as handy.
