Types of Slot Machines


There are many types of slot machines. In this article, you will learn about different types, including Multi-line slots, Random number generators, Multipliers, and Step motors. These machines are more complex than their simpler counterparts, and can be very exciting to play. However, before you start playing, it’s important to understand the basics.

Multi-line slot machines

Multi-line slot machines offer a more simple and straightforward gameplay. As the name suggests, these games are multi-line slots with fixed paylines. This helps in keeping your chances of winning high. The betting limits range from a few dollars to a few hundred dollars per spin. This makes them a great choice for beginners and those who want to practice their skills before playing for real money.

Players should pay attention to the paytables of multi-line slot machines as these contain information on the paylines and coin sizes. By studying the paytables, players can make the right decisions on how much to bet per line. Additionally, they can gain knowledge about different bonus features and strategies. Many gaming services also have a dedicated page that provides more information on these machines.

Step motors

One of the most common types of step motor is a step motor in slot. These devices have a central rotor and eight poles on their stator. Each pole is excited by a current, and two poles may be excited at the same time depending on the direction of the current. They are ideal for automata applications and are easy to install.

Random number generators

Random number generators, or RNGs, are a crucial part of slot machines. These computer chips pick a range of numbers and divide them using a formula. The remainder of the number corresponds to a stop on the reels. Without a Random Number Generator, slot developers wouldn’t be able to prove that their games are unbiased.

RNGs are designed to ensure that all players have a fair chance of winning. Random number generators are tested by a state or an independent testing lab to ensure that they’re accurate.


The use of multipliers in slot machines can add a level of volatility to the game. Multipliers are usually introduced by using stacked symbols and can boost the paylines in the game. These opportunities were not available on old three-reel machines, but modern slots often include them. For instance, you can get 3x or 2x when you hit certain symbols on a payline.

While some online slots only have multipliers in the Bonus Round, some have them on all paylines. However, players must know which multiplier to use in order to maximize their wins.


Jackpots on slot machines are usually progressive, meaning that a certain percentage of each bet is taken toward the jackpot. This percentage is then added to the base jackpot. The biggest jackpots can be paid out in a lump sum, or they can be paid out in smaller increments. The method of payout depends on the software provider and the casino. The larger the jackpot, the less likely it is that it will be paid out in smaller amounts. One of the most popular jackpots is Microgaming’s Mega Moolah jackpot, which is issued as a single large payment, which includes a giant novelty check for the winner.

There are two basic types of jackpots on slot machines: the fixed jackpot and the progressive jackpot. A fixed jackpot is smaller and is won when a player makes a bet on one line. A progressive jackpot is a higher total, and is usually worth millions of dollars.
