So, I noticed a while ago that achievement and level-up popups don't happen in Game of Crowns, and instead will wait for you to leave the game space, and I thought that was really clever!
I think it would be even better if this was applied to quoin (upgrade card) minigame locations!
this came to my attention because i got an IMG quoin in Beam Me Down and leveled up, missing the next quoin because of it :( and while the levels are repeatable, it's so much more convenient (and satisfying) to be able to get them all in one go!
