Our Methodology
SlotZone Ranking & Ratings Methodology
Version: 1.1 (Effective November 2025)
Publisher: SlotZone (https://slotzone.net)
Purpose & Scope
This document defines how SlotZone evaluates and ranks online casinos on SlotZone.net using a 10-point rating system. It specifies updated weighting, dimension definitions, verification standards, and calculation rules. Version 1.1 introduces a rebalanced scoring structure emphasizing both player value and trustworthiness.
Core Principles
- User Protection First. Trust & Fairness remains the highest-weighted factor to ensure verified, safe, and licensed operators.
- Balanced Evaluation. Ratings combine legal reliability with entertainment value and promotional quality.
- Evidence-Based Scoring. All results are based on verifiable sources: regulator data, audits, player tests, and complaint analysis.
- Regional Relevance. Adjustments account for payment options, localization, and licensing suitability per market.
- Transparency & Integrity. Paid partnerships do not affect core ratings; sponsorships are disclosed separately.
Rating Structure & Weights
Each casino is rated using four weighted dimensions combined into a unified 10-point Overall Rating:
| Dimension | Weight |
|---|---|
| Trust & Fairness | 40% |
| Games & Providers | 25% |
| Bonuses & Promotions | 25% |
| Customer Support | 10% |
Formula: Overall (0–10) = round_to_1_decimal((0.40*T + 0.25*G + 0.25*B + 0.10*C) / 10)
Rating Bands
| Score | Description |
|---|---|
| 9.0–10.0 | Exceptional |
| 8.0–8.9 | Excellent |
| 7.0–7.9 | Very Good |
| 6.0–6.9 | Fair |
| 0.0–5.9 | Caution / Not Recommended |
