After fierce 23-game run, Canadian Jeopardy! champ Mattea Roach loses by $1

In the end, it was a single dollar and a clue about two American mayors that ended Canadian Jeopardy! champ Mattea Roach's impressive 23-game streak.

On Friday, Roach lost her 24th game by $1 to Danielle Maurer, a digital marketing manager from Georgia, after being stumped by Final Jeopardy.

Roach ended the game with $15,599, while Maurer — who appeared astounded by her razor-thin win — finished with $15,600.

"It feels still kind of like a dream," Roach said in a news release from the enduring quiz show.

"I really came down here hoping to maybe win one game, and so I still can't believe it. You know, it's strange, obviously I didn't come through in the last one, but I still feel so happy and so lucky to have had this experience."

Roach, 23, left the game with $560,983 US, which is approximately $722,498 Cdn.

The Toronto-based tutor was in the lead heading into the Final Jeopardy round with $19,200. Maurer trailed with $11,400, while the third contestant, operations manager Betsy Hobbs, had $7,400.

The final clue was: "These two mayors gave their names to a facility built on the site of an old racetrack owned by Coca-Cola magnate Asa Candler."

Maurer correctly answered William Hartsfield and Maynard Jackson. Neither Hobbs nor Roach knew the right answer.

"It all comes down to the final wager. Did you wager more than $3,600?" host Ken Jennings asked Roach as she pretended to wipe a tear from her face and turned to grin at the new champ.

Hartsfield, as Jennings noted, is the namesake of the Atlanta airport in Maurer's home state.

"Obviously for a Georgia native that's not so hard," said Jennings, who quickly added that questions are written months in advance and assigned at random.

Roach holds the title for the longest run
