The improvements have added up. To qualify for the 2020 C.T.W.C., players had to achieve a near max-out within 2 hours. This standard of play left behind veterans who had qualified in each of the previous 10 years. Jonas, with his 1 max-out in qualification, entered the tournament ranked 31th among 64. Joseph, having scored a world-record 12 max-outs, came in as the No. 1 seed. By the quarter-final, the entire old guard had vanished. The remaining players were all of the YouTube generation, with many explicitly crediting its algorithm for introducing them to classic Tetris.
