How does our Slot Score work?
SlotRanker uses a transparent scoring formula to compare games on the same 0–99 scale. For standard slots, the score is built from RTP, win potential, feature depth, volatility, game mechanics, layout, bet flexibility, provider reputation, and a conservative popularity proxy.
The popularity proxy is not live play telemetry. It is a derived signal based on available catalogue data, used carefully until real engagement data is available. Every score page shows the category breakdown and confidence level so you can see what the number is based on.
- · Game data — RTP, volatility, max win, bet range, layout, reels, paylines, and feature tags.
- · Mechanics — bonus rounds, free spins, multipliers, Megaways, cluster pays, jackpots, and other gameplay features.
- · Provider context — catalogue-level provider performance, used as a small reputation signal.
- · Confidence — a visible indicator showing how complete the measured data is for that game.
