Usage Guidelines for Jeopardy PowerPoint Game Game Setup Right now, Click File > Save As, and save this template with a different file name. This will keep the template untouched, so you can use it next time! Scroll through the presentation and enter the answers (which are really the questions) and the questions (which are really the answers). Enter in the five category names on the main game board (Slide 4). Game Play Open 2 nd Slide, let the sound play. Click to 3 rd Slide, let the sound play. Click to 4 th Slide and show students the Game Board As you play the game, click on the YELLOW DOLLAR AMOUNT that the contestant calls, not the surrounding box. When the student answers, click anywhere on the screen to see the correct answer. Keep track of which questions have already been picked by printing out the game board screen (Slide 4) and checking off as you go. Click on the “House / Home Icon” box to return to the main scoreboard. Final Jeopardy – Go to Slide 3 and click “Final Jeopardy” button in the bottom right corner, click again for the Question, click again for final jeopardy sound, When that is finished playing click again for the answer slide.
