How We Rate Casinos

At Mary Queen of Vietnam, we understand that choosing a reputable online casino is a critical decision. Our comprehensive rating system is designed to help players make informed choices by evaluating casinos across multiple important factors. This page explains exactly how we assess and rate casinos, including 789bet and other operators.

Our Rating Criteria

We evaluate every casino using six core criteria that matter most to players. Each factor is weighted to reflect its importance in the overall gaming experience.

Bonuses and Promotions

We analyze the quality and fairness of welcome bonuses, ongoing promotions, and loyalty programs. Our assessment includes:

• Bonus value and generosity compared to industry standards
• Reasonable wagering requirements and terms
• Variety of promotional offers throughout the year
• Transparency in bonus conditions and restrictions

Game Selection

A strong casino should offer diverse gaming options from reputable software providers. We evaluate the breadth of slots, table games, live dealer options, and specialty games available to players.

Payment Methods

We assess the range of deposit and withdrawal options, including credit cards, e-wallets, bank transfers, and cryptocurrencies. Fast processing times and low fees are important factors in our evaluation.

Customer Support

Quality customer service is essential. We test support channels for availability, response time, and helpfulness. We look for 24/7 availability through live chat, email, and phone support.

Licensing and Regulation

All reviewed casinos must hold valid gaming licenses from recognized jurisdictions. We verify regulatory compliance and check for any disciplinary history or unresolved complaints.

Mobile Experience

We evaluate the mobile platform's functionality, design, and performance. In 2026, a responsive mobile experience is non-negotiable for modern casinos.

Our Review Process

Our team conducts thorough, hands-on testing of each casino we review. Here's how we work:

• Initial Research: We investigate licensing, ownership, and regulatory status before testing.
• Account Creation: We create accounts to test signup processes and bonus claims.
• Gameplay Testing: Our team plays various games to assess quality, fairness, and RTP rates.
• Support Evaluation: We contact customer service with common questions and issues.
• Payment Testing: We test multiple deposit and withdrawal methods to verify processing times.
• Security Check: We verify SSL encryption and data protection measures.
• Compilation: All findings are compiled into comprehensive ratings and reviews.

Understanding Our Rating Scale

We use a clear five-star rating system:

• 5 Stars: Exceptional casinos that excel across all criteria. Highly recommended.
• 4 Stars: Very good casinos with minor areas for improvement. Recommended.
• 3 Stars: Average casinos that meet basic standards but lack distinction. Acceptable.
• 2 Stars: Below-average casinos with notable concerns. Approach with caution.
• 1 Star: Poor casinos with serious issues. Not recommended.

Each criterion receives its own rating, and the overall rating reflects the combined assessment across all factors.
