// Today's high score

It's most likely you've come to play Tetris® through many hours of button-prodding on the Nintendo Game Boy.  But the real hero is inventor Alexey Pajitnov, a Russian genius with a fixation for puzzles and an affinity with beards.  And N-Blox is my tribute.

Here's how you play.  Shaped blocks (called tetrominoes) fall into a pit where you need to arrange them so they form a complete horizontal line.  Once a line without gaps is created, it disappears and the blocks above fall down.  The more lines you create simultaneously, the more you score. 

N-Blox has the option to play along with the classic Game Boy theme tune.  Press the T key to listen in.  Also, if you find the keys a little slow to respond, press the K key to speed things up.

And remember to take a break every few hours or your eyes will actually go square.
