maybe already reply, but the WOF spins expired in 24h too? or we can keep the wof until a determinate date ?
I think yes, Free daily spins expire after 24 hours. Meanwhile spins that you get from Premium membership have no expiration date.
No, I don't think so. I'm not entirely sure, but I think when you claim WoF spins with free roll they don't expire. It wouldn't make any sense otherwise.
