Second, about the sports book, is the design/software bought? I mean it's 1:1 the exact same as on a different site I play at, same design, same odds, same limits even. Like a 1:1 replica. 
I checked the sportsbook section and it seems that they share the same provider as sportsbet.io etc where odds are usually great for soccer matches and average or underwhelming for other sports.Sportsbet provides stuff like boosts etc though which improves the value of their odds with certain restrictions, but I don't think whale provides similar benefits.
Actually sp.io and whale look very different. The site I compared it with is 1:1 the exact same sports book, and I mean 1:1. I was surprised when I saw that actually so maybe there is some sort of package or whatever casinos can buy, so I was just wondering because I have never seen the same book twice. Having the same odds provider doesn't mean you also have the same design or software running the book on your site.
