"Meet Alex, the Russian Casino Hacker Who Makes Millions Targeting Slot Machines... ...The venture is built on Alex’s talent for reverse engineering the algorithms—known as pseudorandom number generators, or PRNGs—that govern how slot machine games behave. Armed with this knowledge, he can predict when certain games are likeliest to spit out money—insight that he shares with a legion of field agents who do the organization’s grunt work. These agents roam casinos from Poland to Macau to Peru in search of slots whose PRNGs have been deciphered by Alex. They use phones to record video of a vulnerable machine in action, then transmit the footage to an office in St. Petersburg. There, Alex and his assistants analyze the video to determine when the games’ odds will briefly tilt against the house. They then send timing data to a custom app on an agent’s phone; this data causes the phones to vibrate a split second before the agent should press the “Spin” button. By using these cues to beat slots in multiple casinos, a four-person team can earn more than $250,000 a week..." https://www.wired.com/story/meet-al...r-who-makes-millions-targeting-slot-machines/
