I think it’s because the answers are graded by actual people. If it’s anything like real Jeopardy, then spelling doesn’t count (to an extent,) so by having a person go over them, it won’t matter if you switch the order of an ‘i’ and an ‘e’.
Of course, still no reason thy can’t just display the answers afterwards, so you can do your own grading…but usually within a few minutes there are posts on the Jeopardy forums, and then soon on other forms, with a list of all the questions and answers.
I’m all set to go for tonight…though odds are, I’ll have the same problem I usually do, which is categories I suck at…it always seems that one of the other two nights have questions I know better…I always get stuck with too many literature, opera, and world history questions…I suck at those! Give me more science, math, food, and recent pop culture!
