Man is 3,333,360 points. The first  known person ever to achieve a perfect score was an American named  Billy Mitchell on 3 July 1999. It took him six hours and he had to  endure 256 levels. On the final level, and due to a programming  limitation, there is only half of the maze, the right side of the  screen contains garbage characters. Once the ultimate score is  reached, the game locks up, and would require a restart.
