RULES AND INSTRUCTIONS: Teams will pick a category they would like to compete in They can choose between competing from points Only one square can be chosen once and then eliminated from play If the group get the answer right they earn the amount of points as instructed and the game moves on to the next group. If the group answers wrong, the next team has a chance to respond and earn the points There are unknown bonus points hidden in the game where you can get up to 4x the amount of the distributed point value (answer a 100 point question, you get 400 points). YOU MUST GET THE BEGINNING QUESTION RIGHT IN ORDER TO RECEIVE BONUS POINTS! If the question is answered wrongly, the next team will not be able to receive bonus points There are also bonus questions worth up to 200 points each. YOU MUST GET THE BEGINNING QUESTION RIGHT IN ORDER TO MOVE ON TO THE BONUS QUESTION! The team who has the most points at the end wins! Good luck!
