Okay, maybe I am the Undisputed Tetris King, period. Hee hee, j/k. I played the ORIGINAL tetris last night for a while.....starting at level 9....186 lines....wound up at level 18....Total score....over 190,000.
It's basically a game of staying one step ahead of the computer. Once you hit level 15, if your playfield isn't CLEAR except the few blocks you have at the bottom, you're quite possibly screwed.
My mom used to actually put me on punishment because I'd kick her arse sooooooooo bad in Tetris/Dr. Mario (You remember that game? You could SMASH your opponent if you cleared four lines in one shot).
