How this list is built
Dates come from provider announcements and our catalogue sync, bucketed by calendar month (UTC). A date shown as TBC means the provider has named the month but not the day. RTP, volatility and max win appear only once the provider has published them, so early in a month many rows are blank rather than guessed.
Catalogue last changed for this month: 23 Oct 2026. Operators stagger launches by market, so a game can appear at one casino days before another.

Why do some May 2025 slots show no RTP or max win?▼
Providers publish full specifications at or just before launch. We show RTP, volatility and max win only once they are confirmed, so 224 rows are blank for now rather than estimated.
