Whether an old-fashioned One Arm Bandit or a state-of-the-art video slot, the basics are the same: A player inserts cash or, in “ticket-in, ticket-out” machines, a paper ticket with a barcode, then activates the machine by pressing a lever or button (either physical or on a touchscreen). The reels spin and, when they stop, reveal symbols that pay out credits based on the machine’s pay table. Symbols range from classic fruits and bells to stylized lucky sevens. Often, slot games have a theme, and bonus features align with that theme.

Then, in 1963, Bally Manufacturing Company introduced the first electromechanical slot with sensors that allowed all three lines to offer payouts and allowed for multiplier machines. By the 1980s, electronic advances made it possible to replace the mechanical wheels with a Random Number Generator, or RNG, which ensures that each spin is random. The RNG is the heart of a modern video slot, and it regulates clever statistical models built into every machine, such as volatility.
