In the digital age, algorithms are present in banking, healthcare, and online gaming platforms. In the latter case, automated dealers manage games such as poker and roulette. These algorithms are already the standard in physical casinos and digital platforms. They promise impartiality and efficiency, but their opacity raises doubts. There are concerns about bias, manipulation, and fairness. That is why auditing algorithms is crucial. It ensures that systems are fair, trustworthy, and ethical.

Why is it Important to Audit Dealer Algorithms?

Dealer algorithms control key aspects of games. They handle the distribution of cards, the spins of the roulette wheel, and the random outcomes. If not well designed or implemented, they can introduce bias. These biases, whether intentional or not, could benefit operators and harm players. Lack of transparency also breeds distrust. This affects users and damages the reputation of platforms.

Algorithm auditing seeks to evaluate these systems. Its goal is to detect and reduce risks of bias, manipulation or technical errors. It also promotes transparency and fairness. Thus, it protects players’ rights and ensures that casinos comply with legal and ethical standards. Methods for Monitoring and Auditing Algorithms

1. Fairness and Randomness Tests

One of the most critical aspects of dealer algorithms is the generation of random outcomes. To assess randomness and ensure fairness, advanced statistical methods are used such as:

• Monte Carlo tests: These simulate thousands or millions of game rounds to analyze patterns in the results.
• Chi-Square tests: These evaluate whether the distribution of outcomes follows a uniform distribution, as expected in fair games of chance.
• Kolmogorov-Smirnov tests: These compare the observed distribution with the expected theoretical distribution.

These tests allow any anomalies that suggest the existence of biases in the system to be identified.

2. Code Transparency Assessment

An effective audit requires access to the source code of the algorithm. Auditors can examine the code to:

• Verify that there are no hidden instructions that benefit one of the parties.
• Ensure that security and randomness standards are correctly implemented.
• Check the use of random number generators (RNGs) that comply with recognized standards, such as NIST SP 800-90A.

3. Independent Simulations

Auditors can replicate the algorithms in a controlled environment to compare their results with those obtained in real systems. This helps detect possible manipulations in the systems implemented by casinos.

4. Continuous Monitoring

Beyond one-off audits, continuous monitoring of algorithm performance is essential to detect anomalies in real time. This can be achieved through:

• Automated monitoring of gaming patterns.
• Using blockchain technology to record gaming results in an immutable manner, providing traceability and transparency.

5. External Audits

Audits conducted by independent entities are essential to ensure impartiality. Recognized bodies, such as eCOGRA or GLI (Gaming Laboratories International), provide certifications that attest to the integrity of gaming systems.

Challenges in Algorithm Auditing

Despite its importance, algorithm auditing faces several challenges:

• Technical Complexity: Dealer algorithms are often sophisticated and require advanced technical knowledge to evaluate.
• Restricted Access: Casino operators may be reluctant to share source code due to intellectual property concerns.
• Human Manipulation Risks: Even if the algorithm is fair, settings made by operators could alter the results.

Overcoming these challenges requires a combination of government regulation, collaboration between stakeholders, and the implementation of innovative technologies that promote transparency.

Trusted Algorithms

Algorithm auditing is a vital tool to protect fairness and trust in automated gaming systems. Through methods such as statistical testing, code reviews, and ongoing monitoring, it is possible to detect and mitigate bias or manipulation in dealer algorithms. As technology continues to evolve, ensuring the transparency and integrity of these systems will be essential to the future of the gaming industry, promoting a fair experience for all players.
