I visited the website without issue. And I saw the UI and navigate around the forum and also checking the license and other things but when. On the tour, I suddenly got a pop up message that my location is restricted to visit the site/ or power in is not available in my region but I visited the site and everything was normal so what happened?
It happens sometimes with some casino's websites like they sometimes detect you are from a restricted nation, sometimes don't. Maybe it is their false negative detection until their automatic tool turns to accurately detecting you are from a restricted nation or area.
Honestly, it's not perfect but it's not terrible if they always detect users from restricted nation/ area if they try to register accounts. It is only terrible if they allow you register account, fund your account, even bet, and later if you win, they pull the restricted nationality against you and your money.
Power.win's ToS does not have Nigeria in restricted list so did you use VPN or Tor.
