This is a highly effective way to review at the end of the week or before a test and it works with any subject. It forces groups of students to argue over the material and arrive at a consensus. My kids ask me to play this everyday and teachers ask me to teach it to them almost every day. It's easy to prepare. Once you and your student's know the rules, you only need to make a 10-15 question powerpoint the night before.
Also, my students like it so much that I use it as leverage during the week. "Wanna play grudgeball? Then step up your game!"
