I've created a Jeopardy! game in PowerPoint for use in Connect. For the game board, it's a simple table with the numbers (100, 200, etc.) as text. I've added the hyperlinks to other slides in the same file directly to the text. Unvisited is white and visited is the same blue colour as the background. So it is easy to see when you're back on the game board what choices are left. The ones already visited appear blank.
It works perfectly as a PPTX or PPT. It doesn't work when uploading either version to Connect (we always upload to the Content library), nor when previewing using Presenter. The links do work, they go to the correct slide, but the text doesn't change to the visited link colour when returning to the game board.
