the tetris of the death

The principle is not to loose! Muaaahaha! Ok, ok, this ain't make one's laught so...Instead of trying to be funny, let's figure all out :

Control simultaneously the pieces in order to optimize the completion of lines accross the several boards.
Once your lines are completed, they are errased on the current board or all boards (depending on the difficulty chosen at the begining of the game : easy, hard, or super-hard).
You loose (and you will anyway ;-] ) when at least one of the boards is full like the diaper of your beloved newborn.
Of course, reach the highest score by playing as smart as you can. how is the score calculated?

Commands are very simple, here they are if you are a stupid dumbass :

First of all, F11 key switches the site (and the game) into fullscreen mode. This is really much more convenient.
Left arrow shifts your pieces on the left
Right arrow shifts your pieces on the left. Or on the right maybe? I don't really remember...
Down arrow makes your pieces fall faster
Up arrow rotates your pieces
P like...? Pause! You got it, buddy!
Space key makes all pieces fall suddenly and quickly. This allows re-synchronization of your pieces by the way.

Do you get it? Yep? Then go go go! Reach the highest score by playing the game!
