There are many types of slot machines but all work on the same principles. All these variations of slots differ in their number of reels, number of pay lines and the payout percentages.

Straight Slots

These slot machines only play slots games and pay out on the standard pay table. These are the simplest games to play and understand. There are some variations in straight slots also. These variations include:

Wildcard - It is a symbol that substitutes for any other symbol, giving you more chances of a payout because this symbol can be anything it needs to be.

The Multiplier – In this variation, one or more reels has a symbol that multiplies a win by a certain amount usually x2, x3, x5 etc.

Buy A Pay - These slot machines have more than one payout table, and to bet on each payout table costs an extra bet. This means that it costs more to bet, but there are more chances to win as there are different combinations of symbols that can come up on each pay table.

Bonus Game Slots

Bonus game slots are slot machines that offer extra games when you get a certain combination of symbols on the reels. These extra games give you a chance to win extra money for no extra bets. These are some of the best games to play.

Three Reel Slot Machines

Three reel slot machines are the most popular type of slot machines found in online casinos. With a three reel machine, the maximum number of coins must be played in order to win the largest jackpot. According to statistics, a player has 1 in 643 chances of hitting the jackpot on each of the three reels, which is the best probability for a jackpot offered by slot machine.

Five Reel Slot Machines

Five reel slot machines are very similar to the three reel slots. The five reel version features an arm and reels, but instead of having three reels in a row, there are five reels in the row. Although the odds are not as good, many players enjoy five reel slots because they offer a higher pay out on average than the three reel slots.

Multi-Line Slot Machines

Multi-line slot machines include the three reel, five reel and video slot machines. The term multi-line refers to a slots machine that allows a player to place bets on more than one pay line. Regular slots only pay out when a player hits the jackpot. Hitting the jackpot requires that each reel stop on the selected jackpot symbol. A multi-line slot features a jackpot, along with additional line combinations.

Multi spin Slot Machines

Multi spin slot machines are another variation of the slot games. In a multi spin machine, the player deposits money and spin the reels. Once the reels have finished spinning, the player has to choose whether to hold a reel or not. Once the desired reels have been held, the other reels are spun again, and the winnings are paid. Multi spin slots can be three reel or five reel. A three reel multi spin machine contains three rows of reels. Multi spin slot machines have the lowest pay out of any slot.

Progressive Slots

Progressive slot machines offer the largest jackpot of any type of slot. Progressive slots are slot machines for which the jackpot continues to increase until it is won. The jackpot is progressive, growing with each bet made. The final jackpot is taken from a percentage of all the bets played on a group of machines. Progressive machines only pay out their maximum jackpot when someone hits on the particular winning symbols designated for the jackpot.
