In the U.S., the player can play the machine by throwing tokens, cash, or in the newest machines a paper ticket with a barcode into the corresponding hole. Then the slot machine is activated with a lever, button, or pushing the touch screen located on the front side (in the latest versions of machines). The game itself may suggest a certain skill from the player or cannot suggest. In some cases, the illusory impression may appear that participation in the game requires some skill, whereas in fact it is – nothing more than a gamble. The purpose of the game is to win money while playing the machine. Usually the game is based on the coincidence of the symbols either on mechanical reels which stop after spinning, or on the video screen. These symbols are usually brightly colored and easily recognized: images of fruit, simple shapes – bells, animals.
In most games all winning combinations of symbols are usually depicted on the front of the machine. If a player gets one of these combinations, the slot machine gives the winner the money or a prize in any other form, for example, gives him additional free games.
In casinos in Las Vegas and Atlantic City there is the a great variety of slot machines, which, of course, dominate in American casinos, unlike gambling venues in old Europe, where Roulette is the King of any casino. One of the most popular varieties of slot machines – video poker in which players hope to get a combination of symbols corresponding to the winning combination of cards – as in poker. Here we can remember that the very first slot machine was created in 1891 by Sittmanom and Pete on the basis of precisely poker – the most popular card game in the U.S.
One of the most popular types of slots is 9 pay line slots. Usually, they are thematic slots that have graphics and music based on popular films or television programs, for example, “The Addams Family”, and bonus games. Most of them provide an opportunity to play a different number of coins, usually – from 1 to 5 coins per line. The higher the amount of the bet is the higher the payout will be. Recently video slot appeared. They usually have up to 100 pay lines and the number of coins may reach 500.
Of course, classic one-armed bandits continue to exist and the standard 3 – 5-reel slots are of different types.
