How Do Online Casino Slots Work?

Online casino slots work like regular, modern video slots found at most land-based casinos. These slot machines are different from the classic three-reel slot machines that most people are familiar with, but many slot players aren’t familiar with some of the modern casino games like video slots. That’s why I will explain the basics of these types of slots here. For example, what the mechanics of the games are, how bonus features and random number generators work, and the usual return to player (RTP), among others!

Basic Mechanics

Video or online slot machines work by betting along different paylines. Paylines are the different lines you can get successful combinations of winning symbols along. There are usually between 9 and 30 different lines you can win on, but sometimes even up to 100! Some of these lines are the usual ones going straight across or diagonal, but others have zig-zag patterns or other unusual forms. It is important to know what the lines are before you play, so you know where your chances of winning are!

Once you understand where you can get winning combinations you can decide how many paylines you want to bet on. Choosing a higher number will cost more per spin, but it will increase your chances of hitting winning combinations. You can also decide how much you want to bet per line. But be careful, as this can increase your bet amount by a lot, but it can also increase your chances of winning.

Special Symbols and Features

One of the fun things about online slot games are the special features and symbols. The most common special symbol is the wild symbol. This symbol acts as a connector when it is next to any two identical symbols — meaning it can allow you to win even without having the entire line be the same symbol. This makes it easy to win multiple lines at once.

Also, another symbols found in video slots are scatter symbols. These can land anywhere on the screen, and when you get up to three of them (depending on the machine), they can do a number of things. One thing scatter symbols do is trigger free spins or bonus features. And another thing they can do is act as multipliers, making wins increase up to 3x across any payline. However, they do not act as wilds and will take the place of symbols where they land.

Bonus games are little mini-games that can be triggered by scatter symbols. They can be interactive as well. They are fun and are part of the reason why people are drawn to online slot games, since they offer large rewards on top of what is already won in the round! Many people choose which slot to play based on the bonus games available alone, so looking to see what they have to offer might change your mind about which slot to play!

Random Number Generators (RNG)

Random number generators are the beating heart of both video and online slots. They are a part of the machine that produces random sequences of numbers to create your spins. Every time you play slots, it will produce a sequence of numbers and use those numbers to generate what appears when you click to spin the reels. The RNG creates random numbers at hundreds per second and has no memory, so whatever number is available in the hundredth of a second you click is what determines the outcome of the spin.

Return to Player and Winnings

The return to player is the percent of the wagered money that is paid back to the gambler. Video slot machines have a generally high RTP. One thing to remember though is that RTP is calculated by a machine, not by a player or a play session. So a machine with a high RTP is not necessarily going to return that value to you each bet or session, but instead by the machine over a longer stretch of time. RTP is usually higher when you play online slots than it is on land-based slots. Since all online slots have to have their RTP displayed, you can find it by clicking on the ! or ? icons, usually found on the main screen.


A final feature that helps make online slots more popular than regular slots are the progressive jackpots. Most online and video slots have them. A progressive jackpot means that the jackpot grows as the machine is played. The longer the machine has gone without paying the jackpot out, the more money you can win by playing it. Often, the jackpot will be linked across different machines, but sometimes, even games or whole casinos! This can make winnings huge if you are lucky enough. However, you must make the maximum bet in order to win the progressive jackpot though. This is not good if you are on a budget, but if you can afford it and if the jackpot is large enough, trying spin to win it can be worth it!

This is the rough outline of the advantages of online slot machines and the basic mechanics behind them. Online casino slots are a lot of fun to play, and this guide should get you started playing and hopefully winning!
