what are the best free slots with decent payouts?

I’ve been getting more into free slots recently, mostly to mess around and test out volatility before throwing any real coins at a game. It’s wild how much the RTP can vary from demo to real money spins though, so it always leaves me kinda skeptical about the actual payouts advertised in the free versions. Most of the top picks on the homepage are super flashy but my “decent payouts” list so far is actually full of games I just stumbled across in the depths of the lobby, not the main banners. I try to stick with stuff that lets you play as much as you want, not those fake demos that freeze after 20 spins unless you sign up.

I’m not expecting to land max wins or anything, but I’d love to hear if anyone has a solid go-to for free slots that doesn’t just eat all your virtual credits instantly. I feel like some games just keep you treading water and it’s hard to tell which ones would really translate to something worthwhile with actual bets.
