Here's the scoring system for the original Tetris on Gameboy:

code:

single    40double   100triple   300tetris  1200

This is multipled by the game level you're on (or if levels start from 0, level+1)

I´m a beginner game programmer and I´m trying to make a little Tetris-clone.
Where can I find info on the score system in the original Tetris? I saw a post about this in a www-board few weeks ago but I have forgotten where I saw it 8-(

Thanks
