I am in the process of designing an experiential activity for a group of learners which involves using Jigsaw Puzzles. I have thought of lots of ways to do it and lots of debrief ideas to infer after the activity. I will probably create a whole white-paper out of that and share with you soon.

He works at Sententia Games and is one of the top gamification experts. Watch this 3 min video for some nice ideas and the thought process behind good instructional activity design:
