Really appreciate you including me, David!
I created the spinning effect by working with the Master Slide for the game board:
* When the game begins (base layer) the arrow always points to red. I added10 layers (one for each time the learner will spin) on the Slide Master for the game board. Each layer has the arrow pointing in the ending direction of the most recent spin.
* I added spin animation (two rotations) to the arrow on each layer which plays when the timeline starts.
* I created a number variable (%Randomize%) and add 2 to it each time the learner clicks the Spin button.
* I created another number variable (%questionsanswered%) and add 1 to it whenever a question slide is displayed.
* Those two variables then dicate which slide layer is shown when the learner returns to the game board after answering a question.
While the game always plays the same, blue question, yellow, blue, red, green, and so on, to the learner it appears random and their "spin" dictates which topic is presented.
In theory, you could certainly expand on this and have the questions come from question banks which would add some differences to the game.
