if Binance ever launched a game or a gambling casino, all of crypto industry will know about it because Binance is a really popular exchange and trust that such development won't be hidden from the public, since they will need the casino or game to be as popular as their exchange also.
Actually they did for Bplay and theres a lot of evidences for these partnership before but hence the playbread on the other hands is wasnt of a deal or collab.
Cause if Binance supported or got some partnership they at least share it or make some tweak about it whether on socials or maybe event place.
Lots of traces from the past that able to point out or prove their partnership and I guess there's really no question regarding on this matter. maybe their partnership just end up years or many months ago when Bplay didn't get much attention to people since maybe their operation failed and their casino goes down due to lack of interest happened.
Searching for reason regarding on when does Bplay and Binance cutting of their ties but so far didn't find any information related to this situation.
I guess this is close chapter since for many times people confirmed already their past partnership, so there's nothing else left to discuss.
