Since its introduction the slot machines’ popularity has increased over the years and has played an important part in the economies of many countries where gambling is legal. The object of the game is to win money like any other form of gambling. The game generally deals with matching the symbols together. The symbols are colourful and can be easily identified.
The symbols usually depicted are fruit images, numbers or alphabets, or shapes in the form of hearts, bells, or spades. Most of the games have different kinds of combinations to win, generally posted on the front of the machine. If a player is able to match the symbols according to the rule of the game he or she wins.
The player who wins often gets paid by cash or at times by a reward like an extra game or bonus round. To start a slot machine a person has to buy the right to play by inserting cash, coin, or tickets which have a barcode, into the slot designated in the machine.
The types of slot machines used all over the world varies. The reason behind this is because two types of games can be played on two different types of machines known as class II or class III. The class II machines operate from a system known as video lottery terminals whereas the class III machine operates from a central computer system.
The basic characteristics of the class II game are that all players are playing for a prize which is common, it is not necessary to have a winner in every or each game, the game does not end until a player wins and the player must be active throughout the game to recognize and declare his or her win.
In the class III games a player competes against other players or house, each game is self regulating, any outcome is possible and can occur in any of the games and wins are automatically announced. In the US some States have restrictions on the class of slot machines used in casino or gaming areas. In a very specific view all games must have all the class II characteristic’s, if it has a class III characteristic it will be considered as a class III game. The casino has to purchase a license from the State in order to install a class III game but there are no restrictions for class II games.
