Last updated: June 2026 — James Wilson, Hoteldiamondinnkolkata
At hoteldiamondinnkolkata.com, every casino and Aviator game review you read is the result of a structured, hands-on evaluation process carried out by our lead reviewer, James Wilson. We believe Indian players deserve honest, transparent, and thoroughly researched information before they deposit real money at any online casino. This page explains exactly how we assess each platform, what criteria we use, and how we ensure our independence from operators.
James Wilson personally tests every casino site featured on hoteldiamondinnkolkata.com before a single word is written. James has spent years analysing online gambling platforms with a focus on the Indian market, studying everything from licensing frameworks to the mechanics of crash games like Aviator. He creates real player accounts, makes actual deposits using payment methods popular in India, plays the games, and contacts customer support teams directly. No review on this site is written from a distance or based on second-hand information.
James approaches each review as an ordinary Indian player would, not as a journalist given special treatment by an operator. This ground-level testing ensures that what we report reflects the genuine experience of a real user.
Before spending any time on a platform, James verifies its basic credentials. This includes confirming the operating company, checking the jurisdiction of registration, and researching any complaints or regulatory actions associated with the brand. Sites that fail this initial check are not reviewed further.
James registers a genuine account using the same process any Indian player would follow. He notes how long verification takes, what documents are requested, and whether the process is smooth and transparent.
This is the core of our methodology. James deposits real money, claims available bonuses, plays the Aviator game and other available titles, tests withdrawal processes, and interacts with the customer support team through multiple channels. Testing typically spans several days to capture a realistic experience.
Each platform is scored across six key categories using a weighted system. James assigns a score from 1 to 10 for each category, and the final rating is calculated based on the weightings described below.
After testing is complete, James writes the full review based solely on his own findings. No operator has the ability to review, edit, or approve content before it goes live on hoteldiamondinnkolkata.com.
The overall score out of 10 shown on each review page is calculated using the following weighted categories:
| Category | Weighting | What We Evaluate |
|---|---|---|
| Licensing and Safety | 25% | Valid gambling licence, SSL encryption, responsible gambling tools, fair play certification |
| Bonuses and Promotions | 20% | Welcome offer value, wagering requirements, bonus terms clarity, ongoing promotions for Indian players |
| Game Selection | 20% | Availability of Aviator, variety of crash games, software providers, RTP transparency |
| Payment Methods | 15% | Support for UPI, Paytm, NetBanking, deposit and withdrawal speed, minimum and maximum limits |
| Customer Support | 10% | Response time, quality of answers, available channels, availability in Indian time zones |
| Mobile Experience | 10% | App or mobile site quality, Aviator game performance on mobile, loading speed, interface usability |
