This 23-year-old paralegal from Washington, D.C., ended his streak of 13 Jeopardy victories Wednesday with $411,612 in total winnings, good for fourth place on the all-time regular-season winnings list.

Who is Matt Jackson?

Correct. Jackson, who lost to New York City’s Michael Baker, trails only Ken Jennings, Dave Madden, and Julia Collins in money won on the long-running quiz show. He will return for Jeopardy‘s annual Tournament of Champions, set to air Nov. 9-20.

Jackson’s hot streak was characterized by his rarely giving incorrect responses and doggedly pursuing the most valuable clues. He said the key to Jeopardy success is staying energized and focused.

“A returning champion finds out pretty quickly that Jeopardy is actually, under the surface, an endurance contest,” Jackson said in a statement. “A whole week’s worth of episodes gets taped in a day, with maybe 10 minutes of rest between each episode …. A huge part of staying alive as a contestant comes down to whether you can stay alert, and a lot of people tire out quickly while the studio lights are on and adrenaline is high.”

Jackson said he plans to donate 10 percent of his winnings to a mixture of charitable causes. Watch him work in the video above.
