Amy Schneider is the first openly transgender contestant to win "Jeopardy! Tournament of Champions."
Schneider secured the victory in an episode that aired Monday night.
To win the tournament, a contestant had to be the first to win three games in the finals.
Schneider and Andrew He, a software developer, went into Monday's game having won two games.
Entering "Final Jeopardy," Schneider was beating He by $1,400. They both answered the question correctly, but Schneider wagered more.
Schneider said she knew He was going to be a tough opponent when she learned he was in the finals.
“I both wanted to [compete against him] and was afraid of facing him again,” she said. “I knew he was one of the top competitors in the field. He was definitely someone that I knew could beat me because he very nearly did before, and he did a couple of times here as well."
Schneider earned $250,000 for her win.
