Tetris like Source for Bmax?

writing a tetris game is very straight forward, create a matrix, walk trew evry block in it, and for evry block check for the pattern you want, the most important thing is that you anderstand matrix:es, if you dont, then even a tetris game might be hard as a first projekt.

I'm currently working on a tetris/pussel game, but i cant give you the source, sence it is a shareware.... sorry :(
