Online slots are easily the most versatile category of online casino games, with thousands of games available in major online casino lobbies.
From old school classic slots with just three reels and a single payline, to modern-day slots with modern gameplay mechanics and bonus rounds, this game category just keeps on giving.
While other games may be available in online casinos, it is certainly online slots that bring in the most players and keep the action going non-stop.
Our online slots guide is here to teach you how slots work, what you can expect from the, what types of slot games are available, and how to win.
Let’s start out by explaining how slots operate and other secrets behind online slots.
Online slot games display a variety of images on the screen each time you press the spin button. You get to choose your bet size and select the game you are playing, but everything else is down to the random number generator (RNG) that runs the game.
Once the RNG generates the symbols for the spin, they will appear in various positions across the slot’s reels. Popular slots have anywhere between three and six reels, with up to 10 positions on each reel, although most slots only display three or four symbols on each reel.
Once the symbols appear on the reels, they connect across a variety of paylines available in the particular game you picked.
Today, there are games with thousands of paylines, although most classic and old-school slots come with anywhere between three and 25 paylines.
Classic symbols in slot games have to appear on paylines in order to offer payouts, but there are special bonus and scatter symbols that appear in most modern games, which can activate regardless of their positions on the reels.
Stop three scatter or bonus symbols to activate free spins, bonus rounds, and even opportunities to win major jackpots.
Top payouts in online slots are often triggered during the bonus rounds, which means you will want to get a bonus round started if you are looking for that top payout.
A handful of online slot games also feature a progressive jackpot, a special bonus feature that offers insanely big wins to the lucky few players.
A progressive jackpot is a jackpot that loads up over time, as many players play the game in question across all the online casinos that offer it.
A great example of a progressive jackpot game is the Mega Moolah slot by Microgaming, which is available in hundreds of online casinos. Playing Mega Moolah gives you a chance at a multi-million dollar jackpot with every spin you play.
The thing about progressive jackpot games is that they come with high volatility and few base game wins, but also a chance to win a jackpot that could change your life upside down.
If you are playing in online casinos to try and strike it rich overnight, progressive jackpot slots are probably your best option.
The history of slot machines is a long and exciting one, and it all started in the late 1800s when the first mechanical video poker machines were created in America.
Video poker machines featured a deck with just 50 cards, with the extra two taken out to give some house edge, and were often deployed in bars and other drinking establishments across the continent.
At the turn of the century, the first slot machine, dubbed Liberty Bell, was created by Charles Fey in San Francisco. This machine and its successors were responsible for making slot games so popular across the US, all the way until the 1960s.
The 1960s and 1970s were an exciting period in the development of gaming machines, as first video slot machines actually appeared on the market in the production of the likes of Bally, IGT, and WMS.
While these companies continue to dominate the live slots industry in the US, a number of other developers like NetEnt, Microgaming, and Play’n GO have taken over the online slots industry and created many of the games we know and love today.
The growth of the internet and the explosion of online casinos has made online slots more popular than live slots ever were, and this expansion only continues with each passing year.
Here are a few slot terms you should know before you start playing:
Unlike gambling games like blackjack or roulette, slots don’t have a single set of rules you can learn, but they do have a lot of common rules that apply to most games in the category.
To start playing, you will need to load up the game and set up your initial bet. You will choose how much money you want to bet per payline, and how many paylines you want to play. In many games the number of paylines is fixed.
Once your bet is all set up, pressing the spin button will get the reels rolling and determine which symbols appear on the reels.
The symbols on the reels will line up across paylines, and you will be paid in accordance with the winning combinations displayed in the game’s paytable.
Slots are one of the gambling games that don’t allow for too much strategizing, as the outcome of each spin is completely random, and there isn’t any way to predict what will happen next.
For that reason, the best strategies you can come up with have to do with your slot selection and the approach you will have to your betting patterns.
More risk-averse players like to play low volatility games that don’t come with big swings, and will often play such games with a higher bet.
On the other hand, risk takers often enjoy playing the highest volatility games around, which offer massive returns even on small starting bets.
Whichever type of approach you decide to take, remember that there isn’t really anything you can do to fool a slot into activating a bonus round or trigger a jackpot.
You will win whenever you are lucky, and you will lose when you are not. The only strategy you can really have is to have enough money in your bankroll to survive a losing stretch and be ready for when symbols start coming your way.
Our casino experts have compiled a short list of tips and tricks you should use the next time you play online slots to make sure you get the most value for your money.
The higher the game's RTP, the more likely you are to win something. You will be best off playing high RTP games at all times and avoiding games with a low RTP at all costs.
Slot tournaments and other slot promotions allow you to win extra money or free spins on top of your regular wins. Any extra value is always good news, so make sure to use such promos when available.
Playing at a new online casino means you get to claim a welcome bonus. Most bonuses are designed with slots players in mind, so make sure to claim your slots bonuses and play with them whenever possible.
Make sure you are always gambling responsibly and within your financial means. Playing too high and gambling too much can lead to slots becoming a menace instead of harmless entertainment.
With so many slot games to pick from in online casinos, it would be a real shame to keep playing the same games all the time. Make sure to try different slot games and enjoy all the variety.
If you are completely new to the world of online slots, here are a few simple steps that you can follow to get started with slot games without any stress:
The first thing you need to do is select an online casino to play at. You can check out our list of top online casinos and find a site that works well for you personally.

Slots TermsThe number of slots in online casino lobbies has grown exponentially over the years. Keep reading to find out about some of the most common types and categories of slots you will encounter in casino lobbies today:
Video slots are by far the most popular category of online slots. These games display many different images, depending on the slot theme, include sounds and animations, and make gameplay extremely enjoyable with their variety and ingenuity.
Classic slot games resemble those you could play in slot parlors back in the 1970s. These simple games with only a few symbols across three reels are still fun to play and online casinos hold them in their portfolios for old time's sake.
Themed after the popular Japanese Pachinko games, these games are a mix of Pachinko and slots. While gameplay is still mostly slots-based, there will be some fun elements of Pachinko incorporated to make playing even more fun.
Progressive jackpot slots are video slots with a special escalating jackpot in play. The more player play a progressive jackpot game, the higher the jackpot will grow, and the more likely it will be to drop. Most jackpot slots these days also offer a classic video slot gameplay on top of the jackpot opportunity.
In recent times, some slots developers have been focusing on creating games that offer more interactivity and skill-based play. Games like these allow you to impact the outcome of your spins in some ways, making playing them extremely fun and very appealing.
The concept of multi-player slots is a very new one and one that's only been tried on a handful of games. Yet, these games allow you to play together with friends and make playing slots a social activity, which is something that could completely revolutionize the industry in the future.
The majority of today's slot machines come with five reels of three symbols each. Five reel slots are usually video slots in nature and feature all sorts of bonus rounds and free spins for the lucky players.
Unlike five reels slots, three reel slots are usually much simpler games with fewer bonuses and jackpots and more straight-up payouts. Classic slots often come with just three reels and symbols that can only line up across a handful of paylines.
Fruit symbols were among the first to appear on the video slot screens back in the day, and remain popular these days. Fruity slots are recognizable for low volatility, decent payouts for top symbols, and a lot of small payouts along the way.

Online slots are some of the easiest casino games to play. Simply choose the game you want to play, determine the bet size, and press spin to start the game.
There is no single answer to this question. There are thousands of video slots out there today, and all of them include some fun features, lucrative winning opportunities and more. The slot preference will depend totally on your personal choices.
Volatility in slots has to do with how often the slot pays and how big the payouts are. Low volatility slots offer many small payouts, while high volatility slots offer fewer payouts which are larger in value.
RNG stands for random number generator and is the algorithm that randomizes the outcome of each spin you play, displaying random symbols on the screen for better or worse.
RTP stands for return to player and is the number that displays what percentage of money wagered is returned to players in a slot game over the long run. Most online slots have an RTP of 95% or higher.
There is no limit to how much you can win. Some progressive jackpot games offer multi-million dollar jackpots, while wins in regular slots are usually capped to 5,000x to 20,000x your bet per spin.
No! As long as you play licensed slots at licensed online casinos, the games you are playing are not rigged in any way. You will have losing sessions and winning sessions, but it's all down to pure luck.
