The Perfect Inside Job

In 1995, computer programmer Ron Harris orchestrated one of the most sophisticated casino frauds in Las Vegas history. As a Nevada Gaming Control Board inspector, Harris leveraged his trusted position to implement a calculated scheme targeting slot machines across multiple casinos. His primary focus was modifying Keno game software to trigger jackpots through specific coin insertion sequences.

Technical Manipulation and Execution

Harris exploited his deep understanding of slot machine programming by manipulating the pseudo-random number generators that controlled game outcomes. Through careful modification of source codes, he created predictable patterns that would deliver winning combinations when specific triggers were activated.

His accomplice, Reid McNeal, was recruited to execute these predetermined sequences on the casino floor.

Detection and Consequences

The scheme unraveled when McNeal's suspicious $100,000 jackpot win at Bally's Casino drew unwanted attention. Casino surveillance teams flagged the unusual patterns, leading investigators back to Harris's connection with the Gaming Control Board.
