Roger Alan Craig (b. 1977) is a computer scientist from Newark, Delaware. He first appeared on Jeopardy! on September 13, 2010 (the Season 27 premiere) and went on to be a six-time champion. On his second appearance, which aired on September 14, 2010, he broke the single-day cash winnings record with $77,000, eclipsing the previous record of $75,000 set by Ken Jennings in 2004. Craig's record stood until 2019 when James Holzhauer eclipsed it with $110,914 and then broke his own record with $131,127. In 2021, Matt Amodio also passed Craig after earning $83,000.
In 2011, Roger Craig returned to the stage to compete in that year's Tournament of Champions. During the Double Jeopardy! round in the first day of the two-day finals, he uncovered the first of back-to-back Daily Doubles with a $9,000 score. He wagered everything and responded correctly, doubling his score to $18,000. Immediately after that, he uncovered the second Daily Double; again, he bet everything and responded correctly, doubling his score to $36,000. Due to his performance, he won the tournament and the $250,000 top prize.
