How We Rate Casino Games
Ever wondered how we decide which casino games are worth your time? With over 15,000 titles on SlotRanker (and counting), we needed more than just opinions. That’s why we built the Slot Score — a smart, data-powered rating that tells you, at a glance, how good a game really is.
Each game gets a score between 1.00 and 100.00, based on five key factors. The higher the score, the more impressive the game.
What Is Slot Score?
Slot Score is our way of ranking games — not based on gut feeling, but on hard data. It looks at how popular a game is, how it performs, what features it offers, how widely it's available, and what players (and our team) think of it.
You’ll see scores like 93.78, 88.50, or 70.20 on game pages — and yes, those decimals matter. They help us avoid ties and keep rankings sharp.
What We Measure (and Why)
🎯 Popularity – 35%
We track the frequency of searches, clicks, and games played. A game's score improves with more interest.
📈 RTP & Volatility – 20%
A high RTP is advantageous since it indicates improved returns over time. However, we also examine volatility.
🧩 Features & Mechanics – 15%
Free spins, multipliers, bonus buys, Megaways, and other thrilling twists are among the unique features that we reward.
🌍 Availability – 15%
We check for availability in important markets, smartphone compatibility, and the number of casinos that offer the game.
⭐ User & Expert Rating – 15%
We add our own expert review and take into account community votes.
Slot Score Formula (Simplified)
Slot Score = (P × 0.35 + R × 0.20 + M × 0.15 + A × 0.15 + U × 0.15) × 100
Where:
- P = Popularity (normalized traffic and interest score)
- R = RTP & Volatility
- M = Mechanics & Features
- A = Availability & Coverage
- U = User & Editorial Score
The score is then rounded to two decimal places to reduce ties and provide precise rankings.
What Do the Numbers Mean?
| Score | What It Tells You |
|---|---|
| 95–100 | 🔥 Absolute top-tier. Must-play. |
| 85–94.99 | ⭐ Excellent. Player favorites. |
| 70–84.99 | 👍 Solid. Great value. |
| 50–69.99 | ⚖️ Average. Some good, some meh. |
| 30–49.99 | 💤 Below average. Better options exist. |
| <30 | ❌ Skip. Weak or outdated. |
Do Scores Change?
Yes — and that’s a good thing. Games get more (or less) popular, providers update them, and we constantly gather new data. That means Slot Scores shift over time, so your favorite slot might climb (or drop) a few points.
