Tetris:

The inspiration for many puzzle games today will finally be reviewed by yours truly, Doodleheimer. It is a game where you stack as many blocks as you can on top of each-other and eliminate them. You have a screen, and a hole, and blocks fall down into the hole. You must strategically fill in a horizontal line to eliminate that line, and the game goes on for-freakin’-ever. Thank God it’s addicting as hell.
