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: 30 Oct 2026. Operators stagger launches by market, so a game can appear at one casino days before another.
