It’s a low-scoring game, but a fun mathematical situation.

Rob

Russell

Elaine

Tonight’s Final Jeopardy! category is:

U.S. HISTORY

First-order calculations

Joyce needs to go big to cover Elaine; Elaine can cover Rob without falling below Joyce on a double stumper.

Lots of mind games here, which I explore in my video.

Zero wagers

Score differences:
Joyce and Elaine: 700
Joyce and Rob: 1,800
Elaine and Rob: 1,100

200 300 700

Then we add a dollar to the minimum wagers, and subtract a dollar from the maximum wagers.

What actually happened

Rob Elaine Joyce
3,000 4,100 4,800

1,101 1,599 701 1,099 2,001
199 299 699

I guess Rob’s wager makes more sense in light of Elaine’s wager – he can pass her if they’re both right but he gives it up if he’s wrong. I still would have preferred something smaller.

Still awaiting our first name on the Tournament of Champions leaderboard!
