Slots are one of the most popular casino games that offer more payouts compared to the other casino games of roulette, blackjack, poker etc. A slot machine is often referred to as a fruit machine or a poker machine. Sometimes a slot machine is also termed as a one-armed bandit. Charles Fey first invented the one-armed bandit in 1887 in San Francisco, USA. Initially he designed the machine with three spinning reels and five symbols comprising diamonds, hearts, spades, horseshoes and a liberty bell.
Later many improvements were made to Fey’s machine. In 1996 the WMS Industries Inc developed the first video slot machine, which gave the facility of winning an additional payout. Instead of the usual three spinning reels, an online video slot comprises five slot reels. Unlike the three reel versions, which offer only one payline, an online video slot can offer as many as nine paylines. These can also have several other symbols such as wild symbols, multipliers and scatter symbols. Most popular themes used in online video slots are Easter Slots, Halloween Slots, Tomb Raider, Christmas Slots, Hitman etc.
A slot machine has a random number generator that constantly generates numbers. The numbers are automatically generated even when the machine is not in use. As soon as you start playing the machine displays the most recent numbers that would determine the result of the game.
