Jobs!
Daily double is the thing they use in Jeopardy as a bonus spot. You get to pick the bet amount (up to your max earnings at the moment) with a chance to "double" your money. There are usually two in each round I believe, maybe one. I could add it in myself, but that wouldn't stop me from mentioning the sadness I felt at it's absence. If constructive criticism isn't for you then I'm sorry.
