Leverage game mechanics to educate customers on how to best use your product. Given below is an example of such a gamification technique deployed by a company called BugHerd (a bug tracking tool for internal teams).
The company has created a web page that has bugs and they are asking users to report as many bugs as they can using BugHerd. People can participate in this BugHunt competition and get a chance to win a $50 Amazon voucher! A beautiful way to teach people how to use the product.
