Well we've had a few good tries so far, but no-one has managed to go 20 for 20. A Perfect Score will end the game with whomever gets it first, but if there's still no perfect score by Halloween, I'll choose the person who A: submitted the most right answers in B: the shortest amount of time. For instance, if you submitted your answers last night but you got 3 wrong and someone submits answers today who got 1 wrong, they'd be the winner.
It's been close though! I'm impressed with how many right answers I've seen come in. Have you had your try at it yet?
