Are you thinking of ways to gamify your eLearning modules? Are those modules created with Articulate, Captivate or Lectora?
If you have answered yes to both questions, then these posts will be useful for you. I found them in elearningbrothers.com blog and it explains how to include a leaderboard within your eLearning modules.
It requires a Google sheet, one of the authoring tools mentioned above, a bit of coding and a bit of patience. 😉
