A common gambling machine found in casinos all over the world is the slot machine. Known by different names across the globe, they are called "one-armed bandits" in the US, "fruit machines" in the UK, and "pokiesteen patti earn money" in Australia. A random combination of symbols is displayed on spinning reels once the machine is turned on by inserting money. Winning happens when particular symbol combinations show up. A random number generator (RNG) is used in computerized systems to determine the outcome of slot machines, which have evolved from mechanical devices to modern ones. Every spin is independent of the others and has no bearing on them.
