Looking for plugin to help with online scavenger hunt

Hi all,

I’m looking to hold a scavenger hunt for my business, with questions based on things my viewers can find online. The potential for participants is huge, so I’d like to rig something that will allow the hunt to manage itself and prevent me having to be on-hand to give follow-up clues.

I have been looking into using a Quiz plugin, but none of them quite fit my needs. I would like to have one question per page, and the viewer MUST enter the correct answer before being taken to the next question. I would prefer it not to be multiple choice (I think that would make it too easy) but if there are no other options I may have to resort to that.

Does anyone know if there is a plugin that might meet these requirements? I appreciate your help. Thanks!
