Extended biography
Alex Vasilev is the scientific editor and fact checker at Casinoz. He has been with the project since 2010: he started as an editor and proofreader, and over time moved to specialised fact-checking and scientific editing. By first education he is a physicist-mathematician — he graduated from the Moscow Institute of Physics and Technology (MIPT). This background turned out to be key for an editorial team that handles many materials involving mathematics (RTP, volatility, slot dispersion), statistics (payout histories, payout times), and regulatory references.

His work is to verify that casino reviews, bonus programme breakdowns, and analytical materials contain no errors in numbers, names of licensing authorities, references to regulatory documents, or mathematical models. When an author writes "this slot has an RTP of 96.5%", Alex checks against the provider's documentation. When a piece refers to "a UK regulator requirement", he verifies that the requirement actually exists and that the wording is accurate. This work is quiet and invisible to the reader, but it is precisely what ensures that Casinoz does not publish materials with factual errors.

In addition to scientific editing, Alex takes part in localisation quality control — he ensures that technical terms (in slot reviews, bonus conditions, regulatory texts) are translated correctly across all language versions of the platform. If in the German version of a material "wagering" is translated inaccurately, that is in his field of view. This is especially important for reviews with complex mathematics, where an inaccurate translation can radically change the meaning.
Work Experience
Scientific editor and fact checker
2014-09-01 — present
Casinoz
Verification of editorial accuracy: slot mathematics (RTP, volatility, dispersion, specifics of mathematical models), statistics and numerical figures in operator reviews, references to regulators and regulatory documents (Malta Gaming Authority, UK Gambling Commission, Curaçao GCB and others), correctness of technical terms. Additionally — quality control of localisations on technical topics so that terms are translated accurately across all language versions of the platform.
Editor and proofreader
2010-05-01 — 2014-08-31
Casinoz
Start of work at Casinoz: general editorial revision of materials, proofreading, checking style and accuracy of wording. As the editorial team grew and materials became more complex, the focus shifted to verification of mathematics, statistics, and regulatory facts — where the physics-and-mathematics background turned out to be most valuable.

FAQ
What is "fact-checking" in casino reviews?
It is verification of every factual statement in a piece: numbers, names, references to documents, mathematical figures. If an author writes "casino X has a Malta Gaming Authority licence since 2018", you need to check against the MGA registry. If they write "slot Y has an RTP of 96.5%", check against the provider's documentation. If they refer to "a UKGC requirement on affordability checks", find the original and make sure the wording is accurate. Without fact-checking, a review quickly turns into a retelling of marketing, in which errors accumulate and the platform loses reader trust.
Why does the editorial team need a scientific editor?
In online casino reviews there are many areas where regular journalistic fact-checking is not enough. Slot mathematics: RTP is not just a number, it is a probabilistic characteristic with a known dispersion, and it must be interpreted for the reader correctly. Payout statistics: "average payout time of 24 hours" only makes sense if you understand how it was calculated — by median, by mean, including or excluding declined withdrawals. Regulation: document wording is often narrow, and a small error in the retelling can radically change the meaning. The scientific editor keeps all this in view.
What are the most common errors in industry materials?
Three typical ones. First — confusion between "the number of games in the catalogue" and "the number of playable games in a given jurisdiction": these can be quite different numbers. Second — inaccurate description of bonus terms: for example, confusion between an x35 wagering on the bonus amount and an x35 wagering on bonus + deposit — the second case requires wagering roughly twice as much. Third — inaccurate references to regulators: "received approval from the UK regulator" can mean anything from a full UK licence to a temporary certificate in one of the subcategories. These errors often slip in through uncritical translation of press releases.
