I think no one yet won indeed one of the main prizes on the WOF. Sometimes we win 5000 satoshis/RP/lottery tickets but no reports till date that someone won the relax. They stopped advertising a long time ago already (multiple years) but they do have a quite high house edge (5%) on their in-house game, which is a lot higher compared to some casinos where it is mostly at 1%.
Yeah, I also think there is not a single user on this forum who can brag about winning prizes like Rolex, iPhone, or an Amazon card from Wheel of Fortune. If I'm not mistaken, someone once posted a screenshot of winning 50 golden tickets in this thread, and that was probably the biggest prize so far that someone has been able to win from Wheel of Fortune.
