Our purpose is to make your program "unbreakable" even when someone forgets to turn off the Advance on MouseClick in the Transitions box of PowerPoint.

Now suppose, in a Jeopardy project, one has linked from the value box on the Main Jeopardy page (Slide 1) to a question on slide 9. The contestant has given an answer and the Game Moderator clicks to slide 10 to see if the answer is correct. When the moderator clicks a couple of things could happen other than calmly moving to the next slide. The Moderator might accidentally double click, moving very quickly past slide 10 (as intended) on to slide 11 – THAT HAS ANOTHER QUESTION ON IT!! Or, even if the Moderator does simply go on to Slide 10, when everyone sees that answer is right, in the excitement of celebrating the right answer on slide 10, the mouse gets bumped and goes on to slide 11. Either way, another question is compromised (seen before it should be), because someone either forgot to change the setting in Transitions to de-select the "Move to Next Slide on MouseClick" - or maybe the Game Moderator does not know how to make that change. Once a Game Moderator exposes another question, some may begin to think the game is ruined because someone may choose that question next time because they know the answer – or may avoid it because they don't know the answer. What to do?

It may be helpful to talk about the Black Slide and Hidden Slides in a 2 step process:
  1. The Black Slide – First, as one sets up the Jeopardy Game, each value on the Main Jeopardy Screen will link to a question screen (or answer, if one is using the TV version of inverted questions and answers). That question will be followed by an answer screen, but after the answer screen, the file goes immediately to the next question screen. See the Slide Sorter View of PowerPoint while looking at the Jeopardy file you download from the course wiki or the textbook site. We are talking about going from Slide 1, Category 1, 100 point value, to Slide 2, where the 100 point value question is found. You will need to insert a new slide after Slide 2 with the answer to the Category 1, 100 point question, after Slide 2. This slide will become Slide 3. This new Slide 3 will have:
      • Category 1 at the top,
      • 100 points noted farther down,
      • the answer for the 100 point question in large letters a little further down still,
      • a button to go back to Category 1, 100 point question slide, Slide 2, if one needs to return there, and
      • a button to go back to the Main Jeopardy Screen, when the contestants are ready to select anther value for a new question to answer.
      • The current slide that is Slide 3, will become Slide 4.
    1. Now, the problem is how to keep from accidentally going from your new Slide 3 (Answer to 100 point question) to Slide 4 (200 point question). Here is where you insert a new Slide 4 that is all black. (The former Slide 4, that had originally been Slide 3, now becomes Slide 5.) This new Black Slide 4 will have a full screen black button that goes back to the Main Jeopardy Screen, no matter where one clicks. (Use Action Buttons/Custom, under Slide Show, on the PowerPoint menubar.) This protects the game from a Game Moderator's random mouse click from advancing on to the next question, when that may not be the next question the contestants want to choose.
    2. Think about this. You will need to go through the whole set of PowerPoint slides you downloaded, adding an Answer Slide after each Question Slide – then adding a Black Slide after each Answer Slide, as specified above. (You should be able to Duplicate and past the Black Slides. The Answer Slides ultimately will have to be done individually, because each one will have a different answer and need to link back to a different question.) You will need to change the link on the Question slides to go to the Answer Slide, instead of the next highest value question.
    3. You also will need to insert a Black Slide after the Main Jeopardy Screen.
    4. I am calling this safety slide the Black Slide. Actually it could be any color as long as you are consistent to use the same color throughout the file.
  2. The Hidden Slide Feature – But all may not be safe yet! What if the Game Moderator accidentally double clicks on the Category 1, 100 point, Answer Slide - or is using the right arrow key with 2 taps? Now, the screen goes right past the Black Slide and, again, on to the slide that has the Category 1, 200 point question, prematurely exposing it. How will we prevent that?
    1. A Hidden Slide will not be shown when one is advancing from one slide to another, either on mouse click or using the right arrow button. One still can link directly to a Hidden Slide, however.
    2. It may be easiest to see the effect of a "hiding" a slide in the Slide Sorter View. Select a slide to be hidden, then choose "Hide Slide." (On my 2011 version of PowerPoint, this option is the next to the last menu item under "Slide Show" on the PowerPoint Menubar.) The hidden slide will have a zero with a diagonal line through it on the slide, which is also slightly greyed to show it is hidden.
    3. Do not hide the Black Slides.
    4. Hide the question and answer slides between the unhidden Black Slides.
    5. Now, if there is a right arrow tap or a random mouse click to generate an advance slide command from an Answer Slide, one will simply go to the next Black Slide. If there was a double arrow or double click one would go from Black Slide to Black Slide, because one only can go to a Hidden Slide with a direct Action Button command.
We will use this technique again in the Intermediate AIM, Project 2, and I will discuss it more, then. For now, take a look at the abbreviated file BlackSlideHiddenSlideExample.ppt to demonstrate to you the Black Slides and Hidden Slides for the Main Jeopardy Screen and the Category 1, 100 point Question and Answer.
