How We Rate Casinos
At WelcomeBonus.co we review online casinos and bonuses so you can make informed choices. With hundreds of casinos competing for your attention, and not all of them playing fair, an honest, consistent rating system matters more than ever. This page explains exactly how we test and score the operators we cover, and how we keep our content independent and trustworthy. We put every casino through the same process, so the scores you see are directly comparable.
The short version
We check licensing and safety first, read every bonus term in full, test games, banking and support, and only then assign a score from 1 to 5. Operators cannot pay for a better rating.
Editorial Independence
Trust is the whole point of a review site, so independence is non-negotiable for us. Our reviews and ratings reflect the genuine assessment of our editorial team. Commercial relationships never determine the score a casino receives or where it ranks. When new information comes to light — a change in licensing, a wave of player complaints, or a tightening of bonus terms — we revise our verdict accordingly, even if that means lowering a previously high score.
How We Make Money (Affiliate Disclosure)
We believe in being upfront about this. WelcomeBonus.co is free to use, and we may earn a commission when you sign up with an operator through links on our site. This comes at no extra cost to you and does not influence our ratings — it simply funds the research, testing, and updates that keep this site useful. In other words, how we make money and how we rate are deliberately kept separate.
Our Review Process
Behind every score is the same hands-on routine. Rather than judging a casino from its marketing, we use it as a real player would, from sign-up all the way through to cashing out. Here is how a review comes together:
- Verify the licence. We confirm the operator holds a valid licence and check its regulator and ownership.
- Register and deposit. We create a real account to test sign-up, verification (KYC), and deposit flows.
- Read the bonus terms. We examine wagering requirements, time limits, game weighting, and max-cashout rules.
- Explore the games. We review the range, quality, and software providers across slots, tables, and live dealer.
- Test customer support. We contact support with real questions and rate speed and quality.
- Request a withdrawal. We make a real withdrawal to measure payout speed and any friction.
- Score and publish. We combine the findings into an overall rating and write the review.
- Re-check over time. We revisit reviews and update scores when offers or conditions change.
Only after every step is complete do we translate our findings into a number, using the criteria below.
What We Assess
Not every part of a casino matters equally. A generous bonus means little if withdrawals are slow or the licence is questionable, so we weight the criteria to reflect what actually protects and benefits players. The table shows each area, what we look at, and roughly how much it counts toward the final score.
| Criterion | What we check | Weight |
|---|---|---|
| Licensing & safety | Valid licence, regulator, data protection, fairness of terms, reputation. | 25% |
| Bonuses & promotions | Real value, wagering requirements, time limits, game weighting, fairness of small print. | 20% |
| Banking & payouts | Deposit/withdrawal options, fees, limits, and verified payout speed. | 20% |
| Game selection | Range and quality of slots, tables, and live dealer, plus the providers behind them. | 15% |
| Customer support | Availability, channels, languages, and quality of responses. | 10% |
| Mobile & usability | Performance and experience on phones, tablets, and apps. | 10% |
How the score is built
Each criterion is scored individually, then combined using the weights above into a single rating out of 5. A casino can have a great game library but still score poorly overall if, for example, its licensing is weak or payouts are slow, because safety and payouts carry more weight.
Our Rating Scale
That weighted calculation produces a single, easy-to-read score. Here’s what each level on our scale actually means in practice, so you know what to expect before you click through.
| Score | What it means |
|---|---|
| 5 / 5 — Excellent | A top-tier casino we are happy to recommend, with strong licensing, fair bonuses, and reliable payouts. |
| 4 / 5 — Very good | A solid, trustworthy choice with only minor drawbacks. |
| 3 / 5 — Average | Decent but unremarkable, or with some terms worth watching. |
| 2 / 5 — Below average | Notable weaknesses such as slow payouts or restrictive terms. |
| 1 / 5 — Poor | Significant issues. We advise caution or suggest a better alternative. |
Red Flags That Lower a Score
Some problems are serious enough to drag a rating down regardless of how polished the rest of the casino looks. When we encounter any of the following, it weighs heavily on the final verdict — and in the worst cases means we won’t recommend the operator at all.
- No valid licence, or a hidden or questionable regulator.
- Unfair terms such as extreme wagering requirements or very low max-cashout limits.
- A pattern of unresolved player complaints or delayed/denied withdrawals.
- Aggressive or misleading marketing, or weak responsible-gambling tools.
- Predatory bonus traps designed to void winnings.
Keeping Reviews Up to Date
A review is only useful if it reflects reality today, not a year ago. The online casino market moves fast, so we re-check the operators we cover periodically and update bonuses, terms, and scores when things change. The “last checked” date shown on a review reflects our most recent assessment. If a casino closes or no longer meets our standards, we mark it accordingly and point readers to stronger alternatives.
Frequently Asked Questions
Still wondering how it all works? These are the questions readers ask us most often.
Can a casino pay you for a higher rating?
No. Commercial relationships never affect our scores or rankings. Ratings reflect our genuine, criteria-based assessment.
Why does one casino rank above another with a similar score?
Rankings consider the weighted criteria and current offers. Two casinos with the same headline score can differ on safety, payouts, or bonus fairness.
How often are reviews updated?
We re-check operators periodically and whenever a major change happens (new licence status, changed bonus terms, or complaint patterns). The “last checked” date shows the latest review.
What should I do if I find outdated information?
