The classic computer game
addiction; those famous shaped bricks cascading through the increasingly
testing, neverending series of levels. 
Most people have come to know Tetris through hours of playing on the
Game Boy. But the real hero is a one Alexey Pajitnov — a Russian
genius with too much time on his hands and an affinity with beards.
For the Tetris novice: shaped blocks fall into a pit where you must
rotate and arrange them to fit neatly in solid lines at the base. A
completed line with no gaps in the brickwork on that level will fade
away, the layers above it will then drop down giving you more space
to work in. You'll learn to appreciate that space and you'll need to
have your wits about you to keep up with the pace.
Oh, and remember to take a break after every few hours.
