IIT-BHU study validates fairness of Random Number Generators in online card games
IIT Banaras Hindu University, Varanasi, has confirmed through an independent study that Random Number Generators (RNGs) used in online card games meet high statistical fairness by Dr Bhaskar Biswas, Professor and Head of the Department of Computer Science and Engineering, the research applied internationally accepted methodologies to evaluate the randomness and integrity of card shuffling non-Personally Identifiable Information gameplay data from RummyCulture, the study examined both 53-card and 106-card formats over a three-month TESTING USING DIEHARDER SUITE
The team used the globally recognised 'Dieharder' statistical test suite, a benchmark for RNG quality, to assess thousands of card distribution tests evaluated multiple aspects of randomness, including uniformity, independence and findings showed that RNGs passed 97.34% of all Dieharder tests for 53-card games and 98.25% for 106-card games.P-value distributions were largely uniform in both cases, with only minimal clustering at the edges, which is consistent with theoretical expectations.'These results demonstrate a high level of statistical conformity and provide reassurance about the robustness of RNG implementations in digital card games,' said Dr Biswas. 'In games such as online rummy, the underlying randomness must be beyond reproach.'FIRST ACADEMIC VALIDATION OF REAL-WORLD RNG DATAThis is the first time in the skill-based Real Money Gaming and wider global gaming industry that an independent academic body has analysed actual gameplay RNG IIT-BHU team conducted multiple Dieharder tests, such as the Birthday Spacing Test, Bitstream and Rank Tests, Parking Lot and Minimum Distance Tests, and DNA and OPSO/OQSO results consistently confirmed no detectable bias or predictability in RNG AND INDUSTRY SIGNIFICANCEThe report highlights the regulatory importance of these findings. RNGs in digital gaming are subject to audits under standards like NIST and the British Remote Technical IIT-BHU study confirms that the tested systems meet these which previously earned RNG certifications from iTech Labs (ISO 17025 certified), sees the study as a reaffirmation of its commitment to fair to the platform, such independent validations help maintain ethical standards, boost player trust, and ensure sustainable growth for the online gaming industry.- Ends
