Here are some debate games that can be really fun and teach some basic skills that are useful in round. They can also help with team bonding. 

This is a game for students to attempt to make links that seem minimal and even silly. Since links are an important part of debate, while this is a silly way to learn the basics, it does help us gain those skills. This can also help with team building. 

This game teaches creativity, thinking on your feet, and finding arguments where there don't seem to be any. Also, this game usually results in a lot of laughs. 

This game forces students to take a side that they may or may not agree with, a skill that helps with both debate and life.
