How We Review Online Casinos
Every casino listed on Online Casino Spider goes through a rigorous multi-step review process carried out by our team of experienced analysts. We test each platform ourselves — we do not rely solely on operator-provided information.
Our 7-Step Review Process
1. Licensing & Regulatory Compliance
The first thing we check is whether a casino holds a valid licence from a respected regulatory body. We only consider casinos licensed by authorities such as the Malta Gaming Authority (MGA), the UK Gambling Commission (UKGC), the Dutch Kansspelautoriteit (KSA), or the Gibraltar Regulatory Authority. Unlicensed casinos are never recommended.
2. Security & Fairness
We verify SSL encryption, evaluate the use of certified Random Number Generators (RNGs), and check whether the casino undergoes regular independent audits by organisations such as eCOGRA, iTech Labs or GLI. Player funds must be held in segregated accounts.
3. Bonus Terms & Wagering Requirements
Welcome bonuses are assessed in full detail. We analyse wagering requirements, eligible games and their contribution percentages, maximum bet restrictions, time limits and any geographical restrictions. We flag bonuses with unreasonably high wagering requirements or unfair conditions.
4. Game Selection & Software Providers
We evaluate the breadth and quality of the game library, noting which software providers supply the content. We look for a healthy mix of slots, table games, live casino, and other categories. We also assess mobile compatibility and loading performance.
5. Payment Methods & Withdrawal Speed
We test deposit and withdrawal processes personally. We assess the range of supported payment methods, minimum and maximum transaction limits, processing times, and any fees charged. Fast and fee-free withdrawals score significantly higher in our ratings.
6. Customer Support
We contact each casino via all available support channels — live chat, email and telephone where offered — to test response times, knowledge and professionalism. We specifically test how each casino handles complaints and disputes.
7. Responsible Gambling Tools
We assess the availability and accessibility of responsible gambling tools including deposit limits, loss limits, session time reminders, self-exclusion, and links to support organisations. Casinos with strong player-protection infrastructure score higher in this category.
Our Rating Scale
Each casino receives a score out of 5 based on a weighted average across all seven criteria above. Licensing and security carry the highest weighting. A casino scoring below 3.0 is not recommended on our platform. Our ratings are reviewed and updated at least every six months, or immediately if we receive credible player complaints.
Editorial Independence
Our review scores are determined solely by our editorial team and are never influenced by affiliate fees, advertising spend or operator requests. Casinos cannot pay to receive a higher rating. Our affiliate relationships are fully disclosed and do not affect our editorial conclusions.
