Casinos introduced slot machines for the wives and girlfriends of gambling husbands with the intention that men would get more time for you to spend on gambling. At this point, the game is now very popular amongst both women and men visiting the casinos. Instant jackpots and ease to play are several of the reasons why increasing amount of people are drawn towards slot machines.

Casino slots can be classified into straight slots and progressive slots. Straight slots have set jackpot payouts based on the machines payout schedule. As an example, if playing on a straight quarter slot, winning a jackpot by betting on a quarter will give 200 coins, a two-quarter bet wins 600 coins, and also the jackpot amounts to 2000 coins. However, progressive slot machines have jackpots tied into a bank of machines, a carousel of machines, or maybe other machines at a different casino. The progressive jackpot is displayed on an electric board, which is attached to the progressive slot machines. Further more, the progressive jackpot increases with every play on each slot machine of the progressive group. The payouts on progressive slots can reach to extremes as well as can cover anything from several thousands to multi-million dollar payments.

A casino has a number of other attractions for example the 3-reel slot machine, 4-reel slot machine and the 5-reel slot machine. Often odds increase with more reels in a slot machine. Another attraction includes the fruit machine, and uses a video monitor in place of standard reels. Similar to these, various new slots are introduced in casinos every season. Every time they come up better gimmicky names and enhanced digital effects, thus maintaining and raising the attraction.

These slot machines are designed with a feel and look of the conventional mechanical models, however they work on a complete different principle. Dissimilar to the conventional mechanism the outcome of each pull in modern slots is controlled by a central computer inside the machine, and not by the motion of the reels.
