Just encountered this news -
"DuckDuckGo blocked in Indonesia over ..., gambling search results." which has dropped a bomb on me. I have never been in this country and always thought it is loyal to gambling. But it seems to be not. How does the matter lie at present? I wonder this because of my plans to visit Indonesia for a couple of weeks and when visiting countries for the first time I commonly show myself round the local casinos.
Unfortunately you will not find any legal land based casino in Indonesia because all forms of gambling are prohibited here.
If someone invite you to play at an illegal land based casino here, it's better not to do that because it could bring complicated problems for you if the police caught you there.
And if you play online on a phone, I suggest not to do it in public places, and you also have to prepare a VPN or change DNS when using a cellular/wifi network because everything has been blocked by the internet providers here.
