Hoopa quest
Forum-Index → Help → Answered → Hoopa quest"After freeing Hoopa, the real Quest begins and Professor Rowan asks you to find five Prison Rings which are spread randomly all over PokéHeroes, excluding the forums and special event pages. Those five golden rings will remain at their locations after the quest has been started and you collect them by clicking on one.
The Quest is mobile and desktop friendly and it doesn't require scrolling, so if you visit a site and don't see a golden ring on the current screen, you can stop your search on this page and move on to the next one."
Taking this into consideration, the rings stay in a set location and do not change. They will be at the top of the page, so if you do not see it, you can move onto the next page. Look around! Maybe there are places you haven't visited.
Hope this helps.
