RULES – DOUBLE JEOPARDY
RULES• Players: 2-3• Players play rock, paper, scissors to determine who chooses which question first and
second.• After choosing who goes when, the first player picks the first question under any
category.• If the question is answered correctly, the player earns whatever number of points the
question is. (i.e. graphing for 500 = 500 points)• If the question is answered incorrectly, the player loses however many points the
question is.• During Daily Double, the point amount for the question is doubled. (i.e. 200 regularly =
400 points for DD)• You may use a calculator.• At the end of the game, there is one final question, Double Jeopardy. Players can bet
200-1000 points (that they currently have) on the question, and if answered correctly, they earn that point amount. If answered incorrect, the points are lost.
• Whoever has the most points wins.• Calculators are allowed only in graphing.
