I have tried all the usual things like flushing the browser cache and also trying other browsers, but the wheel has just stop spinning for me. I have had this before and it resolved it self, so I guess the problem is on their side.
In any way, I do not know why I am even trying to spin it anymore... it only gives a small amount of Satoshi and never anything else. Have anyone actually won something bigger than the small rewards?
It worked well for me today too and good thing that they fixed it before spins got expired.
Basic rewards got lower because Bitcoin price went up. I think it's not bad to get 30 Satoshi or lottery tickets without doing anything. It's more about that higher tier rewards become more rare. It's been a while since I got bigger reward from WOF, maybe month or two ago. Back when they introduced it I was getting 500/5000 Satoshi probably few times every week, once got 50 GT. But later they changed something, probably to reduce costs and big wins become rare.
