It's hard to believe that the development lasted two years. But it is possible that two years ago someone had an idea and its implementation took so long. This often happens when someone has the main job and builds such a project slowly in their spare time. There is also the possibility that the domain was simply bought from someone.
Maybe bought or maybe waiting for the right time to launch it, it's not easy launching a casino, you need good software, a good script, host and of course you must know the in and out of the gambling industry, but now they are already here hope they can take care of their business that took over two years to launch.
