PLAYBUS

N-Blox

N-Blox is an unofficial clone of the original Tetris. Most people have come to play Tetris through hours of button-prodding on the Game Boy. But the real hero is one Alexey Pajitnov: a Russian genius with too much time on his hands and an affinity with beards, and N-Blox is my tribute.

How do you play? Shaped blocks fall into a pit where you must arrange them so they fit neatly. A sort of juggling in one direction. The more blocks you can place into a horizontal line simultaneously, the more you score.
