Last updated: May 2026 — Ethan Walker, Grandprix Valdys
At Grandprix Valdys (grandprix-valdys.com), every review you read is the result of a structured, hands-on evaluation process carried out by our lead reviewer, Ethan Walker. Our mission is simple: to give players in Uzbekistan honest, data-driven assessments of online gambling platforms, starting with our detailed coverage of Mostbet in 2026. This page explains exactly how we work, what we measure, and why you can trust our conclusions.
Ethan Walker is the author and owner of Grandprix Valdys. He brings years of hands-on experience evaluating online casinos and sports betting platforms across multiple regulated markets. Ethan personally registers real accounts, makes real deposits, tests bonus claims, plays games, contacts customer support, and processes withdrawals before writing a single word of any review. No review on this site is based on second-hand information, operator-supplied press kits, or affiliate briefs alone.
Ethan's approach is grounded in the principles of Experience, Expertise, Authoritativeness, and Trustworthiness. Every claim in our reviews is backed by direct testing evidence, screenshots, and documented interactions with the platform being evaluated.
Before touching the platform itself, Ethan researches the operator's ownership history, regulatory record, and player reputation across independent forums and community boards. This gives us essential context before the hands-on phase begins.
Ethan creates a real player account using the same process available to users in Uzbekistan. We document every step of registration and KYC verification, noting how long it takes and whether the process is transparent and straightforward.
We fund the account using payment methods commonly available to UZ-based players. This allows us to evaluate both the deposit process and the practical availability of banking options for our target audience.
We claim available welcome bonuses and promotional offers, then read the full terms and conditions. We track wagering requirements, game restrictions, and expiry dates in real time to give players an accurate picture of real bonus value.
Ethan spends meaningful time across different game categories — slots, live casino, sports betting, and table games — evaluating software quality, game variety, loading speeds, and user interface design.
We reach out to the support team through every available channel (live chat, email, phone where applicable) with standard and complex queries. Response times and quality of answers are recorded precisely.
We request a withdrawal and document the full process: how long it takes, what documentation is required, and whether the experience matches what the platform advertises.
The platform is tested on mobile browsers and any available native app across different device types, assessing performance, navigation, and feature availability on smaller screens.
After completing all testing steps, Ethan scores the platform across six core categories. Each category carries a specific weight in the overall final score:
| Category | Weight | What We Evaluate |
|---|---|---|
| Licensing and Safety | 25% | Valid gambling licenses, data encryption, responsible gambling tools, fair play certifications |
| Bonuses and Promotions | 20% | Offer value, wagering requirements, transparency of terms, ongoing promotions |
| Game Selection | 20% | Number and variety of games, software providers, sports markets, live dealer quality |
| Payment Methods | 15% | Deposit and withdrawal options, processing times, fees, availability for UZ players |
| Customer Support | 10% | Availability, response speed, helpfulness, language support |
| Mobile Experience | 10% | App or mobile site quality, performance, feature completeness on mobile devices |
Final scores are presented on a 1 to 10 scale, calculated as a weighted average across all six categories. Here is what each score range means:
Independence is the foundation of everything we do at Grandprix Valdys. While our site may earn referral commissions when readers follow links to casinos, these commercial relationships never influence our scores or written conclusions. Ethan Walker determines every rating independently, based solely on the testing evidence collected during the review process.
We do not accept payment for positive reviews. We do not allow operators to preview or alter review content before publication. If a platform performs poorly during testing, that poor performance is reported accurately, regardless of any existing affiliate arrangement. Our readers in Uzbekistan deserve honest guidance, and protecting that trust matters more to us than any commercial consideration.
Our methodology is reviewed and updated regularly to reflect changes in industry standards, new regulatory developments in 2026, and feedback from our readership. If you have questions about how we rate a specific platform, you are welcome to contact Ethan Walker directly through the contact page on grandprix-valdys.com.
