free spins counted only losing spins toward promo progress

So I was working through a free spins promo and noticed the progress bar was creeping way slower than usual. After digging into the rules, turns out only my losing spins are getting counted toward the promo requirement, not every spin. Basically, if you hit a win, that spin doesn’t move you closer to the goal, just the losses do.

Has anyone else run into this? It’s honestly kind of weird to me and pretty different from how other promos I’ve done usually work. Usually, I just have to play through a set number of spins or wager a certain amount, not just burn through losing spins. Seems like it punishes hot streaks, and you end up grinding longer if you’re having any luck.

Would love to hear how others handle these, especially if you manage to actually clear the thing. I like consistency, but this type of rule feels a little off.
