Slots were developed more than a century ago, and today you can play them not just at land-based casinos, but also online casinos. Slots initially started as machines that used just one coin and offered one payline. However, today there are many different types of slots that offer multiple payline and huge jackpots.
There are many different types of slots, ranging from straight slots to progressive slots and from 3-reel slots to 5-reel slots. Some of the most popular types of slots are described below:
## Straight Slots:
This type of machine has a payout chart, and if you have a combination of symbols that are mentioned on the payout chart, you will win. This type of machine is not associated with other games of slots. Therefore, the jackpot paid by each machine is different. There are primarily four types of straight slots, and they are multiplier slots, bonus multiplier slots, multiple payline slots and buy-a-pay slots.
Multiplier Slots: Here the payout depends on the number of coins you bet on each spin. For instance, if a slot machine pays 10 coins for getting a winning combination of three cherries on a bet of one coin, you will end up winning 20 coins for getting a winning combination of three cherries on a bet of two coins. So, if you bet three coins and get the winning combination, you will win 30 coins. Basically the basic payout is multiplied by the number of coins that are wagered.
Bonus Multiplier Slots: This type of slot is similar to the multiplier slots, but involves a bonus that is paid if the maximum number of coins is wagered. For example, if you bet one coin for getting a combination of three cherries, you will win 10 coins. If you bet two coins for the winning combination, you will win 20 coins. But if the maximum number of coins that you can bet with is 3 coins, instead of winning 30 coins as you would in multiplier slots, you many end up winning 50 coins.
Multiple Payline Slots: When slots became popular among casual casino gamers, the machine offered a single payline. However, today, the case is different. Each coin that you insert in the machine ends up activating one payline. If the winning combination of symbols is listed on an activated payline, you will win a payout. However, if the winning combination of symbols is not part of the activated payline, you will not be paid. The 3-reel slots and 5-reel slots are multiple payline slots.
The 3-reel slot machine has three reels and three paylines, while the 5-reel slots have 5-reels and the payline offered is from 5 to 21.
Buy-a-Pay Slots: This type of slot can end up confusing the most ardent slots lover. Here the machine offers different winning combinations and you have to buy the combinations. In effect, you will only be paid for the winning combination if you have bought it. For instance, a machine pays for getting three cherries, three gold bars and three sevens. One coin activates the three cherries combination, two coins activate the three gold bars as well as three cherries combinations and three coins activate the three sevens combination as well as the other preceding two combinations. So, if you bet just one coin, and the payline shows three gold bars, you will not receive any payout. However, if you bet two coins, and the payline displays three gold bars, you will receive a payout.
## Progressive Slot Machines:
These slot machines are connected to a network of machines. It is not necessary that the machines in the network are based in the same location. The machines can be located even in different casinos. The concept followed by the progressive slot machine is very simple. Every time a player places a bet in any of the machines that are part of the network, a fraction of the bet is added to the jackpot.

**Bonus Game Slots:
** In this type of slot machine, the player wins bonus games if he or she gets a particular combination of numbers or symbols. The bonus games allow the player to get additional chances of winning more bonus games or money without having to wager any more coins.
