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.
ZapLab review
Halloween and monsters make up the theme of ZapLab (Elk Studios, 2025), seven reels, fixed paylines. At 94.0%, RTP is clearly below the catalog median of 96.06% — arguably the most important thing to know about this game. Volatility is high, and no maximum win is listed, so it can't be compared with the catalog.
