If there's a gambling website which accepts Bitcoin they HAVE TO open an announcement & support thread in Bitcointalk. Look I don't say they "should" but they "HAVE TO". Otherwise that site is %99 scam and I wouldn't play in that site.
Sometimes websites with topics on bitcointalk can be scams...
I do not gamble at new websites. why should i when i can gamble at most popular dice/casinos websites?
