Tetris 2 is more similar to Dr. Mario than the original Tetris in that the goal is to match the colors of the descending tetrominoes with pre-positioned blocks on the play field. When three or more blocks of the same color line up, they are eliminated. When three or more blocks are lined up with the special flashing blocks, all blocks of that color are eliminated at once.

nymx took to creating a Tetris 2-solving, multi-instanced bot program to solve the game as efficiently and quickly as possible. Do see the author's submission notes to learn more about the creation of this TAS, which took over two years to complete.
