Any ideas for good review games for students?

I am a first year high school math teacher. I have some fun ideas for review games before tests to use with my students. We have played all sorts of games like Jeopardy, Basketball, even variations of Who Wants to Be a Millionaire. I like to use these games because the kids get really involved and excited about learning when it's fun. But I'm always looking for more ideas to help my students. Are there any ideas you might have for fun review games for high schoolers?
