How We Rate Casinos
At Kolkata Net Service, we evaluate online casinos with a comprehensive methodology to help Indian players find safe, reliable platforms for games like 1win Aviator. Our ratings are based on rigorous testing and analysis across eight key criteria.
1. Licensing & Regulation
We prioritize casinos with legitimate licensing from recognized authorities. Our assessment includes verification of:
- Malta Gaming Authority (MGA) licenses

Casinos without valid licensing receive significant rating reductions, as this is the foundation of player safety.

We thoroughly review promotional offerings and their conditions:
