Our Review Methodology
Every casino reviewed on Casino Sultan is evaluated against a standardised 40-point checklist covering licence validity, bonus terms and wagering requirements, game library size and provider diversity, withdrawal speed testing with real deposits, mobile compatibility, customer support response times, and responsible gambling tools.
We never accept payment for positive reviews. Casinos that fail our minimum standards are not listed. Our affiliate relationships do not influence ratings — if a casino pays us a higher commission but scores poorly on our checklist, it ranks lower regardless.
