Directions for Changing the
Game
• To change the questions and answers, just type
over the problems…Use the “replace” feature to
change the categories easily
• The daily doubles were originally set to category
#4 for $500 and category #2 for $300
• To change the daily doubles you must
– 1. Change the hyperlink for the links on the main board
to go to the appropriate question, therefore bypassing
the daily double slide
– 2. Change the hyperlink on the continue button on each
daily double slide to go to the new question.
