Actually, they were AdGem (Family Island and Merge Garden). I’ve been having good luck with AdGem - download a game, play the tutorial, get sats (it’s about 50/50 whether that works), and getting level rewards in Alice’s Dream Merge Island. It’s the “Turn Your Skill Into Sats” callout.
The other callout (“Tap, Play, Earn”) takes me to the Playtime URL and I’ve only had 1-3 games show up, and the one I tried didn’t pay out so I stopped going there.
Interesting we’re having opposite experiences I’m on iOS, so that probably has something to do with it.
