Lol great ideas, keep it coming. Here's mine:
WT Study: The Game
You are given an issue of ObservanceZiggurat, in effect an article with random words scrambled, with 3-4 words not being random, and actually having some meaning. You have to read through the nonsense trying to find the words that form a meaning and mark them.
Phase two: in the study group each paragraph is taken one at a time, and when you are sure you got your words marked correctly, you press a button to answer. You are not guaranteed to be picked though. If you are picked and your marking is correct, you get points and the chance to be picked next time for answer is raised by a small amount, if it's wrong you get minus points, and the chance decreases.
It's a bit harder than it looks, because the random words could apparently make sense too, but it would not be correct to mark them, so you should only try to answer on paragraphs that you are sure you got right.
