About Jonas
Jonas Berg is the Data & Trust Index Methodologist at BestCasinoPortal, working from Stockholm, Sweden. Over 11 years in online gambling, Jonas has concentrated on trust index model, data analysis, methodology — the areas that most directly decide whether a casino is safe to play and worth your money. To date, Jonas has contributed 23 hands-on casino reviews and 15 published articles to the site.
That experience shapes a practical, player-first approach: clear about what an operator does well, and honest about where it falls short. Jonas's wider knowledge spans data analysis, casino rating methodology, trust and safety, and every rating is grounded in evidence — licence checks, real-money testing and complaint history — rather than operator marketing, then revised whenever the facts change in 2026.

How Jonas reviews casinos
When Jonas assesses a casino, the process follows our published standards rather than personal preference. That means verifying the operator's licence against the regulator's own register, testing real deposits and withdrawals, reading every bonus term in full, and checking complaint and payout history before any score is assigned.
The result feeds our transparent Trust Index, which is never for sale. You can follow Jonas's work across our casino reviews and guides, and every recommendation is paired with clear responsible-gambling guidance — because the safest bet is one you can always afford to lose. 18+.
Every review and guide by Jonas is independently fact-checked against regulator registers and our published Trust Index methodology before it goes live. The score is never for sale.
