About Gemm Sales

Gemm Sales is an independent review platform dedicated to helping US players find the best Ethereum casinos. Our team tests every casino we recommend with real ETH deposits and withdrawals to verify transaction speeds, bonus terms, and game quality.

We are not a casino. We do not accept deposits or process wagers. Our revenue comes from affiliate partnerships with the casinos we review. This means if you click a link on our site and register at a casino, we may earn a commission at no additional cost to you.

Our editorial process is independent of our business relationships. Affiliate partnerships do not influence our rankings — we rank casinos based on our 10-factor evaluation methodology, weighted by ETH transaction speed, bonus fairness, game selection, and security.
