What Are the Different Types of Slot Machines?


If you’ve ever played a slot machine, you know that each spin is a gamble. You press a button, and a series of thousands of numbers spin in the background. When those numbers stop, the computer program correlates them with the symbols, and displays the symbols when only one number is left. While the odds of winning are fairly consistent, each spin will be different.

Machines with three reels

If you are fond of old school slots, slot machines with three reels are an excellent choice. These games are easy to play and do not require you to download any special apps. Three reel slots are also easy to play for free. However, be sure to check for progressive jackpots if you want to win the maximum amount of money.

The payline in a slot machine refers to the horizontal or vertical line that pays if you get three matching symbols. Usually, the lowest stake on a three-reel slot is lower than that of a five-reel slot machine. However, this does not necessarily mean that three-reel slots offer a lower chance of winning progressive jackpots.

Machines with multiple “lines”

Multi-Line slots are real money slots that have multiple “lines” or paylines, and each line counts as a separate bet. The more “lines” a slot machine has, the more money a player can win. A typical Multi-Line slot machine has between three and five lines, and some can have up to nine or more. Each payline will have a different jackpot value.

When playing multi-line slot machines, you should never play more than one coin per spin. Although the extra coin will increase your chances of hitting a winning combination, it will not increase your long-term payback. Bonus Multipliers, however, are a great way to increase your long-term payout. The downside of Multi-Line machines is that they can be extremely frustrating when a winning combination does not appear on the active paylines.

Machines with weighted reels

Weighted reel slots use a similar concept to conventional slots, but the symbols are given greater weights to increase the chance of hitting a winning combination. These types of machines are more common at land-based casinos. They offer multiple paylines and dozens or even hundreds of ways to win, boosting the player’s bankroll.

In the 1980s, manufacturers began programming slot machines to automatically weight symbols to reduce the probability of losing a symbol. They did this by weighting symbols based on their weight and their frequency on the physical reel. Weighting symbols increased the overall weight of the machine, because symbols can sometimes occupy more than one stop.

Machines with computerized random number generators

Computerized random number generators (RNGs) are a vital part of slot machines. These systems generate random numbers every millisecond and translate them into a specific set of numbers to match the symbols that are on the reels. These random numbers are used to determine the payout of each spin. The RNG is activated when a player presses the spin button or deposits a coin.

A computerized random number generator is designed to generate results independently of a player’s previous purchases or wins. The machine never reacts to previous purchases, credits, or previous winning combinations. Since the results are completely random, players can’t predict the outcome.
