Tetris is Hard, Made Easy
From Meritology
Author's Abstract
In their paper "Tetris is Hard, Even to Approximate", Demaine, Hohenberger and Liben-Nowell show that optimally playing the "offline" version of Tetris, where the initial board and piece sequence are known, is NP-hard. This is done by reducing the so-called 3-Partition problem to this "offline" Tetris problem. In this document a much simpler way to accomplish the same is suggested.
