Some sort of them are acceptable, but not all. You can't just open up a casino in Turkey and get people to gamble on blackjack or something (not that there is a big addiction going around i nthe youth today unfortunately all due to online ones) but at the same time you can gamble on sports anytime you want, and yo can play on lottery, there are some sort of different gambling games that you can even buy on the street, like scratch cards and so forth. Which means that, not ALL forms of gambling is allowed, but there are few different type of gambling games that are allowed by the government at the moment, been like that as far as I can remember, maybe got a bit more modernized in the past 10 years, but it has been limited but allowed in some sort of forms one way or another for decades.
