1. Real-money gaming apps must hold valid gambling licenses in operating countries and submit them in Play Console; 2. Operate only in approved countries — Google Play only allows listing where you hold a license; 3. Implement age verification (≥18, ≥21 in some countries); 4. Provide responsible gambling tools (deposit limits, self-exclusion, cooling-off periods); 5. Never market real-money gaming content to minors.
