Modern gaming machines use computer technology to operate their functions. Slot machine outcomes are determined unsing a Random Number Generator (RNG) which is a mathematically-based program that selects groups of numbers to determine which symbols are selected to produce a winning or losing outcome.
While some people may think that slot machines are completely random, this is not actually the case. Slot machines are programmed with special algorithms to ensure they remain fair for all players and create an exciting gaming experience.
