CVData has code to sim them by special license and I know someone who had a magnificent run over a couple years. BUT, they have changed the operation since and the code is no longer useful. Doesn't mean that they are unbeatable. Two things to keep in mind. A game that casinos think is not beatable (and this also applies to 6:5) means low radar. Secondly, there are countries that cannot ban your play or spread based solely on the fact you win. This has been tested in courts.

Having said that, I can't blame CBJN for dropping 6:5 as they need reporters and few reporters have any interest in such.
