How We Rate Casinos

At Chris Does Maths, we evaluate online casinos using a comprehensive methodology to help New Zealand players find the safest and most rewarding platforms. Our ratings are based on rigorous testing and analysis across eight key criteria, listed below in order of importance.

Licensing & Regulation

Player safety is our top priority. We only recommend casinos holding valid licenses from recognised regulatory bodies such as the Malta Gaming Authority (MGA), UK Gambling Commission (UKGC), Curaçao eGaming, or local New Zealand authorities where applicable. We verify active license status and review regulatory compliance records to ensure your funds and personal data are protected.

Game Selection & Software Providers

A quality casino offers diverse gaming options from reputable software developers. We assess the variety of slots, live casino games, table games, and specialty offerings. We verify partnerships with trusted providers and evaluate game performance, fairness certifications, and RTP (Return to Player) rates.

Bonus Terms & Wagering Requirements

We scrutinise bonus offers beyond their headline value. Our analysis includes wagering requirements, rollover conditions, maximum cashout limits, game restrictions, and expiration periods. We highlight casinos with transparent, player-friendly T&Cs and flag those with unfair bonus terms.

Payment Methods & Withdrawal Speed

We evaluate the range of deposit and withdrawal options available to NZ players, including credit cards, e-wallets (PayPal, Skrill, Neteller), bank transfers, and cryptocurrency. We test withdrawal processing times and assess minimum/maximum transaction limits to ensure convenient and timely access to your winnings.

Customer Support

Responsive, knowledgeable support is essential. We assess 24/7 availability, multiple contact channels (live chat, email, phone), average response times, and support quality. We contact casinos ourselves to evaluate helpfulness and professionalism in resolving common player issues.

Mobile Experience

Most NZ players access casinos via mobile devices. We test responsive design, load times, and game functionality on smartphones and tablets. We also evaluate dedicated mobile apps (if available) for user experience, navigation, and feature completeness.

Responsible Gaming Tools

Protecting player wellbeing is crucial. We verify the presence and accessibility of responsible gaming features, including deposit limits, session time limits, self-exclusion options, cooling-off periods, and links to support organisations like Gamblers Anonymous and Problem Gambling Foundation NZ.

Our Rating Scale

We rate casinos on a scale of 1 to 10:

• 9-10: Excellent – Outstanding across all criteria; highly recommended for NZ players
• 8-8.9: Very Good – Strong performance with only minor areas for improvement
• 7-7.9: Good – Solid offering; meets standards but lacks some premium features
• 6-6.9: Acceptable – Meets minimum requirements; some concerns noted
• 5-5.9: Fair – Significant limitations; approach with caution
• Below 5: Poor – Not recommended; serious regulatory or operational issues

Each criterion contributes weighted points toward the final score. No casino receives a recommendation without proper licensing and responsible gaming tools, regardless of other strengths.
