With 18th Jeopardy! victory, Canadian champ Mattea Roach continues to soar

Mattea Roach extended her winning streak on Jeopardy! to 18 games on Thursday, further cementing her legacy as the most successful Canadian ever to compete on the program.

With 18 wins under her belt, Roach, a Toronto-based tutor, has the eighth highest total for consecutive wins on the program.

The 23-year-old Roach started off Thursday's game strong, nailing four of five questions about world landmarks.

Roach went big on her final wager and emerged the winner, winning a total of $42,001 US.

Over her 18-game and still-continuing win streak, she has won $438,183 US.

Roach has been making headlines as she racks up win after win on Jeopardy! this spring. 

If she manages to win yet another game on Friday, she will pull even with two other prior contestants — David Madden and Jason Zuffranieri — who each put together 19-game streaks.

At this point, no one from Canada has won more games in a row than Roach. 

But competitors from Canada who came before her had impressive win streaks of their own.

Here's a look back at a few of the multi-game winners who have spoken to CBC News over the years about their Jeopardy! adventures.

In 1988, Vancouver's Barbara-Anne Eddy won five games on the show, bringing home $52,000 US — a haul worth more than $128,000 US today, when adjusted for inflation.

But Eddy was no trivia rookie, as she'd competed on multiple game shows over the
