Triggers and conditions

I have a quiz in which I need to click on various hotspots in order to proceed to the next slide, I would like the question to be as open as possible so the user can click on any hotspot in any order but only the correct sequence will progress to the next slide, anything else will branch off to a feedback layer.

I think I have been on Storyline a bit too much right now as my mind has gone blank on how to work this out.

Any ideas will be gratefully received.
