I am afraid to make it. In my country, gambling is forbidden. If making a gambling place, in the end will only deal with the police.
It may be forbidden, but we are in the crypto world, it's anonymous.
You can create an anonymous gambling site, you don't need to write or state where are you based at.
By the way, if you are only creating the platform and you are not running the platform( you code the site, but you are not the owners or taking any part at managing the site) then you won't have any problem to do that even from a country where gambling is forbidden.
It's okay to work for the site, as long as you don't have any part of it it's okay.
