You cannot just take payments from citizens of the USA or Europe into some unregulated country, forever. Sure, some fly under the radar, but most gambling-like games (including puzzle games) belong to some conglomerate.
See online casinos. They exist since the 90s, before apps. In the USA apparently you can only run a casino in Las Vegas or some places with a soecific license. Yet the online casinos still exist, but operate from jurisdictions that are off limits from the FBI or whatever (something like Cayman Islands or whatever). However the owners are identified and will be detained when entering US soil.
The internet is not some loophole to break the law. If you are taking a relevant amount of money, even in small payments, they can get back to you or at least block you.
