I have 2 gems at the moment. I had like 178 a while ago because of all those daily questions (that gave you gems) that would pop up when you entered the app. It would give 3 gems per question, but there was always a glitch where it would pop up like 4-6 times haha.
I tried reading Episode originals for gems, but then I decided it wasn’t worth it. I just try to complete the “challenges” (or whatever they’re called when you open Episode daily/read Episode).
