Review Methodology: How We Grade Online Casinos
By Jack Thornton | Fact-checked by Dr. Lisa Harrington | Updated: 1 April 2026
Why Methodology Matters
In an industry where most review sites offer little more than subjective impressions dressed up as assessments, CasinoCheck AU has built a structured, repeatable methodology that we publish in full. Our commitment to transparency means that every reader can understand precisely how we arrive at our grades — and challenge our conclusions with the same data we use.
This page documents our complete assessment framework, including category definitions, weighting rationale, grading thresholds, and testing protocols.
The Seven Assessment Categories
1. Withdrawal Speed and Reliability (25% weight)
This category carries the highest weighting because our investigation has consistently identified payout performance as the single most impactful factor in the Australian player experience. We measure:
- Average withdrawal processing time across bank transfer and cryptocurrency channels
- Consistency of processing times across multiple test transactions
- Presence or absence of withdrawal obstruction tactics (unnecessary re-verification, stalling, maximum payout caps)
- Transparency of withdrawal terms and conditions
Each casino receives a minimum of five withdrawal tests across different methods and amounts. Timelines are documented from the moment of request to the moment funds are received.
2. Game Library Quality and RTP Accuracy (20% weight)
This category assesses both the breadth and integrity of the game offering:
- Total number of available titles
- Provider diversity and reputation
- RTP verification through independent cross-referencing
- Presence of provably fair games
- Game loading speed and performance
- Regular library updates and new title additions
We verify RTP figures on a minimum sample of 40 titles per casino, comparing published values against provider documentation and third-party audit data.
3. Licensing and Regulatory Compliance (15% weight)
- Licence verification through public registries
- Licensing jurisdiction assessment (regulatory stringency, player protection mechanisms)
- ACMA compliance status
- Responsible gambling tool implementation
- Terms of service transparency
4. Customer Support Responsiveness (15% weight)
- Live chat response times across multiple test interactions
- Agent knowledge and problem-resolution capability
- Email support turnaround time
- Consistency of support quality across different times and days
- Availability of support channels (live chat, email, phone)
Each casino’s support is tested a minimum of 12 times across varying days and hours, including weekends and public holidays.
5. Bonus Transparency (10% weight)
- Clarity of wagering requirement disclosure
- Reasonableness of wagering multipliers relative to market standards
- Presence of hidden conditions (maximum bet limits, game contribution weighting, time limits)
- Ongoing promotional value beyond the welcome offer
- Mathematical modelling of expected bonus cost
6. Security Infrastructure (10% weight)
- TLS encryption implementation quality
- Two-factor authentication availability and type
- Data handling and privacy policy assessment
- Account security features (login notifications, session timeouts)
- Vulnerability response posture
7. Mobile Performance (5% weight)
- Page load and game launch times on 4G and Wi-Fi
- Battery consumption during extended play
- Touch interface optimisation
- Feature parity between mobile and desktop
- PWA support and functionality
Grading Thresholds
Our numerical scoring translates to letter grades as follows:
| Grade | Score Range | Interpretation |
|---|---|---|
| A+ | 95-100 | Exceptional across all categories |
| A | 88-94 | Excellent with minor shortcomings |
| B+ | 80-87 | Strong performer with identifiable gaps |
| B | 72-79 | Competent with notable limitations |
| B- | 65-71 | Adequate but with significant concerns |
| C+ | 58-64 | Below average with multiple weaknesses |
| C | 50-57 | Poor performance across key metrics |
| D | Below 50 | Fails to meet minimum standards |
No casino in our current rankings scores below B, as operators that fall below this threshold are excluded from the published list entirely.
Testing Timeline
Each assessment follows a structured 30-day minimum protocol:
Days 1-3: Account registration, KYC verification, initial deposits across multiple payment methods.
Days 4-14: Active gameplay across pokies (minimum 50 titles), live dealer (minimum 10 sessions), and table games. RTP verification sampling begins.
Days 15-21: Withdrawal testing commences. Customer support evaluation through 12+ interactions. Security infrastructure assessment.
Days 22-28: Bonus terms verification. Mobile performance benchmarking. Data compilation and cross-referencing.
Days 29-30: Scoring, grade assignment, and editorial review. Fact-checking by Dr. Lisa Harrington.
Quarterly Reassessment
Published grades are reassessed every quarter through a condensed 10-day review cycle. Between quarterly reviews, we conduct unannounced spot checks to monitor for material changes in operator performance. If a significant change is detected, the ranking is updated immediately with an editorial explanation.
Limitations and Disclosure
Our methodology is designed to be rigorous but is not infallible. Limitations include:
- Testing is conducted with Australian accounts and may not reflect the experience of players in other jurisdictions.
- RTP verification relies on provider documentation and third-party audit reports; real-time server-side configurations cannot be independently verified without operator cooperation.
- Our sample sizes, while substantial for an independent review outlet, represent a fraction of total player interactions at each casino.
We disclose these limitations in the interest of transparency and invite readers to factor them into their assessment of our conclusions.
