Doris first gained notoriety in 1983 when she achieved a world record score of 1,112,300 points on the classic arcade game Q*Bert during Twin Galaxies’ 1983 Video Game Masters Tournament, an event that was conducted for the Guinness Book of World Records. She was 58 years old then, the oldest person up to that time to capture a video game world title.
