Upper level high school and even university students can still benefit from games, especially as a review tool. "Jeopardy" springs to mind immediately as a kind of game that can go from easy to challenging and cover all the ranges of learners in your class. I'm watching "Are You Smarter Than a Fifth Grader?" on TV these days and I like the format of that game show (similar to Who Wants to be a Millionaire?) as well. I may actually try to integrate it into my classes in the future for fun and for educational purposes. Yes of course university students are not going to play Duck, Duck, Goose or whatever, but there is plenty of opportunity for games at all levels.
