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.
Koschei The Deathless review
Koschei The Deathless from Spinomenal, released in 2023, is tagged with a Halloween/horror theme, even though the name references a Slavic folklore character — the data itself gives no further plot details. It has five reels, fixed paylines, and high volatility. RTP of 96.04% is practically level with the catalogue median of 96.06%. No maximum win figure is listed, so the ceiling can't be compared with the catalogue.
