Directions: Scroll through the presentation and enter the answers (which are really the questions) and the questions (which are really the answers). Enter in the categories on the main game boards. As you play the game, click on the TEXT DOLLAR AMOUNT that the contestant calls, not the surrounding box. When they have given a question, click again anywhere on the screen to see the correct question. Keep track of which questions have already been picked by printing out the game board screen and checking off as you go. Click on the “Game” box to return to the main scoreboard. Enter the score into the black box on each players podium. Continue until all clues are given. When finished, DO NOT save the game. This will overwrite the program with the scores and data you enter. You MAY save it as a different name, but keep this file untouched!
