I also think that Maverick Games uses Pinnacle as their sports betting odds provider. There are several articles discussing their partnership just like this one:

If you are looking for a new sports betting platform, try Blackjack.Fun or Sportsbet.io. They are both reputable online casinos with sports betting support.
