Ask HN: What Agile / Kanban / Scrum Tools Use Gamification for the UX?

I am looking for Agile, Kanban, or Scrum tools that present a fun and gamified UX experience. This is surprisingly hard to search for. I recall a SaaS tool about a year ago that presented a fantasy theme for small teams. I cannot find that product, nor is there really a segment of Agile etc that focuses on Gamification. There are Agile games, though they are for instruction, and learning the Agile concepts. Any help appreciated, and of course hn is where I turn because this is probably where I read about it awhile ago though the search feature is NOT turning it up!
