A Hot Spot learning interaction can contain up to eight distractors (choices). To change the default number of six distractors, add more distractors or delete existing distractors.
In general, you place the hot spot distractors over another graphic that the user is really intended to see. To make hot spot assets semi-invisible during authoring to visualize this effect, turn the alpha effect setting down on each hot spot. The interaction scripts override this setting at runtime.
