Why the RTP at a casino may differ
Providers ship the same game in several return configurations, and each casino picks which version it runs. Across the market the spread typically runs 2–8 percentage points below the headline figure. The number here is the provider specification — the version actually running is shown inside the game, in its rules screen.
Ultra Cluster Kingdom review
Seven reels is unusually many for a video slot, and that's the count for Ultra Cluster Kingdom from GameArt. The name also reflects its payout format — cluster pays. The theme is ancient, released in 2024. Its RTP of 96.22% practically matches the catalogue median of 96.05%, with high volatility. No maximum win figure is listed, so its ceiling can't be compared with the rest of the catalogue.
