How We Rate Casino Games

We use a structured, repeatable scoring system designed to evaluate casino games objectively. Every game is assessed using measurable criteria - not personal preference. Each review results in a final score from 0 to 10, calculated using a weighted formula. This page explains exactly how that score is produced.

Core Evaluation Framework

Every game is evaluated across six weighted categories. Each category contributes a fixed percentage to the final rating.

Game Mathematics - 30%

Evaluation Principles

  1. Personal taste is excluded from scoring.
  2. Games are compared only within their segment (e.g., high-volatility slots vs high-volatility slots).
  3. Mathematical data is prioritized over visual appeal.
  4. Alternative RTP versions are noted separately.
  5. If Bonus Buy changes expected value (EV), it is documented.

Adaptation by Game Type

While the framework remains consistent, weight distribution may shift slightly depending on format:

Relation

Slots Default structure
Crash Games Increase weight of Risk Profile
Instant Games Increase weight of Mathematics
Live Casino Increase weight of Technical & UX
Game Type Adjustment
Slots Default structure
Crash Games Increase weight of Risk Profile
Instant Games Increase weight of Mathematics
Live Casino Increase weight of Technical & UX

About The Author

Ivan Rodeo, Slots.Rodeo author
Ivan Rodeo

I review online gambling content with a mechanics-first approach: how games pay, what the paytable/rules actually state, and what the client discloses about RTP/volatility/limits. For casino reviews, I focus on licensing and ownership disclosures, payment/withdrawal terms, country restrictions, and responsible gambling tools. Reviews follow a fixed method:

  • Verify core rules in the in-game paytable/rules (symbol rules, bonus triggers, feature conditions) or in official casino terms (licenses, limits, withdrawals).
  • Capture primary evidence (screenshots from a demo/client UI, or the casino's published terms pages) and use it as the main reference.
  • Cross-check key details against provider documentation and regulator/licence records when available.
  • Separate confirmed facts from interpretation (what is stated vs what a player should realistically expect).
