How do I Create a grid and check what tile occupies adjacent

Hi,

I have a puzzle game idea where I rotate large tiles made up of 4 smaller tiles, if you match squares of the same colour of smaller tiles then those tiles are destroyed and any small tiles above them fall down Tetris style.

I'm conceptually having a problem with how to start this prototype, I want to define a grid and have a way of detecting 'shapes' made up of different tiles within the grid. Any ideas where to look for this?

Interesting, I will list that kind of puzzle to my to do list. Meanwhile you might want to check my collapse puzzle example >>
