Jeopardy 20 Squares Start Rules: Each group has a white board and a dry erase marker One group chooses category and point value Every group answers If a correct answer is given, that group receives points. If the group that chose the category and point value gets the answer correct they receive an additional two points. If an incorrect answer is given, no points are awarded. If the group that chose the category and point value gets the answer wrong, two points are deducted from their score. Start
