FlipQuiz and is a great tool for teachers. I love the idea of having teachers introduce themselves using this Jeopardy board. Of course, you can't get enough of Jeopardy and everyone knows how competitive student can get when reviewing for an assessment. Check this one out, because the set up is easy on the teacher's part. Just put in your questions and answers, and you are ready to play. You will have to create a FREE account however before getting started, but that's so with everything.
