In December 1982, eight-year-old boy Jeffrey R. Yee received a letter from United States president Ronald Reagan congratulating him on a world record score of 6,131,940 points, possible only if he had passed level 256. In September 1983, Walter Day, chief scorekeeper at Twin Galaxies at the time, took the U.S. National Video Game Team on a tour of the East Coast to visit gamers who claimed the ability to pass that level. None demonstrated such an ability. In 1999, Billy Mitchell offered $100,000 to anyone who could pass level 256 before January 1, 2000. The offer expired with the prize unclaimed.
