Slide Click Through: Puzzle -> Hint -> Solution

Hello – I’ve got K-12 math-puzzle slides that are in triples. Slide 1 has the puzzle. Slide 2 has a hint. Slide 3 has the solution. I want clicks to automatically cycle through the slides. I don’t want the slides cropped or any arrows or dots appearing on the slides. I also just want a fading transition from one slide to the next… nothing fancy. Do you recommend a powerpoint plugin or something else?
