Mobile App Gaming, Contest, Gambling Law and Compliance

I am looking for a Freelancer to support me with regards to legal compliance related to mobile app gaming, contests and gambling, in multiple countries. I need assistance with reviewing the existing systems to ensure they comply with applicable regulations, as well as terms and conditions required.

I need to know in which countries/jurisdictions within countries it is legal to have a mobile app game that is completely free to play (never need to deposit), is completely luck based (no skill required) where users can withdraw money if they win. I would like to know for these countries:

China
India
United States
Indonesia
Brazil
Russia
Japan
Mexico
Germany
Nigeria
Vietnam
United Kingdom
Turkey
France
Philippines
Egypt
Italy
South Korea
Thailand
Iran
Spain
Argentina
Pakistan
Bangladesh
Poland
Colombia
Ukraine
Canada
South Africa
Australia

This project includes researching applicable laws and regulations, ensuring that gaming, contest, and gambling systems are compliant.

The Freelancer should be familiar with the intricacies and potential risks associated with products involving gaming, contests and gambling. The successful applicant will provide regular updates on both the project status and research findings. This project requires great attention to detail, meticulousness, and strong communication skills. The ultimate goal is that the client complies with all legal requirements pertaining to gaming, contests, and gambling in the US and globally.

Thanks
