Marie Günther
Expertise & Focus
Marie specialises in licensing and player safety, bonus policies and wagering terms, payment flows and KYC, and slot/provider analysis. For DACH readers she explains how rules differ across Germany, Austria and Switzerland, and what this means for bonuses, age limits (18+), and cash-out reliability.
Review Methodology
Every review follows the same checklist: create an account, make a small real-money deposit, trigger and test a withdrawal, and verify KYC and responsible-gaming limits. She audits bonus T&Cs, licence status and certificates, checks game providers plus RTP/volatility, and samples player feedback on sources such as Trustpilot and Reddit. All findings go through final editorial verification before publication.
Local Focus: Germany, Austria & Switzerland
For Germany, Marie tracks GGL guidance on licensing and advertising standards and how these affect bonuses and deposit limits. In Switzerland, she follows ESBK (for casinos) and GESPA (for lotteries/sports betting) to clarify what’s legally available online. In Austria, she references oversight by the Federal Ministry of Finance (BMF) and practices around payment methods like EPS and SEPA; for Germany and Switzerland she often compares Sofort/Klarna, Giropay and TWINT for speed and fees.
Experience & Facts
In iGaming since 2014; 50+ reviews and guides on AThEME; 100+ slots assessed across major studios; publishes in English and German; covers DACH and wider EU markets.
Staying Current
Marie monitors official regulator updates (GGL, ESBK/GESPA) for rule changes and enforcement actions. She reads industry analysis from EGR Global and iGB to spot product trends, market data and compliance shifts that affect DACH players. Release notes from leading studios help her track new mechanics and volatility profiles.
