&gt;If you played Tetris at the slowest possible speed for the rest of your life, you could possibly never lose. The only enemy would be fatigue. But the algorithm for beating Tetris is not complicated, and you have plenty of time to move the pieces to their optimal locations.<p>I believe this is inaccurate. If you play long enough, you always lose. Proof: You cannot cleanly make lines with only s-pieces. If you assume a random distribution of pieces, you eventually get a string of s-pieces long enough to exhaust the game board, though you can keep it going for a very long time.<p>I would like to hear this uncomplicated algorithm for beating tetris.
