It might make a decent information site .. it's not a bad name ... however I think anybody big who wants a casino will want a brand for their entire casino ... the only game different enough and with enough critical mass of players to merit a separate branding is poker ... that's because players play vs other players (not against the casino in theory) more than anything else.
That being said .. Craps is a special game that with special players that potentially could be marketed to directly .. but if that were the case they'd probably pick a prefix other than "all".
So at the end of the day you might get an inquiry or two eventually .. but I'd let it go for cheap because it'll more likely be an information site than a real gambling site.
Good luck with it ...
You might want to try to sell it to
