I did a quick research and I found multiple articles dating back to 2023 talking about a partnership between maverick.game and pinnacle solution. So, I think pinnacle is their odds provider.
But as I couldn't find any official source for this information, it would be better to reach out their customer support or pm their pr (as yahoo suggested) for confirmation.
Can we find the information online for the list of odds providers? I also did some quick research but didn't see Pinnacle being an odds provider; it was just a sportsbook per my research. About Maverick Games, I checked their ANN thread and there was indeed a user posting that they received an email about the sportsbook closing soon, but the official representative hasn't made any announcement yet.
@JinKuang, I'm just curious, so I would like to ask. How can you compare this certain sportsbook in terms of odds to the popular ones like Sportsbet and Stake?
