Types of Online Slot Machines 

To make it easier to choose, here’s an overview of game types you’ll find in a casino lobby:


The term video slots refers to just about any online slot machines and games. All computer casino games are videos, and slots are no exception. The games have multiple paylines and payout options. Most people have the idea that playing slots in a casino involves pulling the lever and watching the screen to hope that symbols line up in the middle. You’ll find that even physical casinos are using automated video slots. These are easily translated into online games. Video online slots have thousands of options for themes and graphics.

Fruit Machines

The simplest variety of slots out there, and probably the most common game you’ll see across the board. These are super entertaining because they usually have a bunch of bonus games and features but still keep it simple.

3-Reel Slots

This type of game is simple and straightforward. It’s a great transition for someone who’s used to playing slots in person. You’ll have fewer storylines, but still plenty of themes and graphics to choose from. The rules are simple – match three in a row and win. Sometimes you’ll gain free spins too. You may come across wild symbols, which can take the form of any graphic necessary to complete the line.

5-Reel Slots

Great action for experienced players or beginners looking for something other than the usual. A lot of these games have elaborate storylines and graphics, so you’ll feel like you’re being transported into another world while you’re playing. In other words, it’s a more immersive experience. These games also have more options for winning (like multiple paylines, wilds, and scatters), so check the game rules before you play.

Progressive Jackpot

This fun innovation adds to the entertainment of slot games by having player bets contribute to the jackpot. So every time any player spins, a little bit is added to the jackpot pile – so the more you play, the more you can win. While the odds of hitting the jackpot are slim, they’re not impossible, so if you’d really like to test your luck, this slots game may be worth the payout.

Mega Spin Slots

Is one slot game not exciting enough? Then try mega spin slots, where you can spin a bunch of slot machines at once! You can have six, nine, or even 12 games that you turn with just one click, multiplying your chances of winning. 

3D Slots

You won’t need special glasses as providers haven’t quite come up with a way to make computer games 3D, but when you see this in a casino lobby, it means that the games focus on creating realistic, detailed graphics.


This is a lively feature for slot games, powered by Microgaming. Multiplayer mode allows you to get social while you’re home gambling online. If you miss the ability to talk to other slot players or want to gamble with your friends, you can do that through online slot machines. There are a few different multiplayer games available, and each will work differently. For example, the extremely popular Avalon Slot Game (Microgaming) now has a multiplayer version where you’ll be “seated” at a slot machine, and you can use a chatbox to talk to the players sitting around you. Players come from all over the world, making it even more exciting.

Try them all and see what games work for you! If you want to start with free slots rather than real money, head to our games lobby and get spinning!

Guide for Online Slots

Like many other online casino games, real money slots are nothing like the ones you’ve experienced before. There are multiple reels, paylines, and various symbols and rules you should examine that will help you reach your full gambling potential.

Slot Game Features

Online slot machines have multiple combinations that give payouts. The rarer the symbol that lines up, the more coins you win. You should know all about the different ways to win real money with casino slots.


This refers to the lines on which payouts are awarded if a winning combination of symbols appears on it. Simply put, these are the slot machine ‘lines’ you see on your screen. If you’re playing 3-reel slots, your paylines are the three reels going across, and you must get three matching symbols across that playline to win. Online, you may win through a number of combinations, including zig-zagging paylines. Check your specific game’s rulebook to see which combinations are winners. 

Games with fixed paylines require users to play with the same lines throughout the game. You may have one or more paylines that win money. Adjustable paylines allow users to choose – you can increase the number of paylines or decrease them, which affects how much you score.


Each game will have a different ‘wild’ symbol. Look out for that across your screen! Wilds transform into a standard symbol that’ll help you win – which is why they’re a fun favorite of players. It’s always exciting when wilds pop up on the screen, as they increase your chances of creating a winning combination. If you’re lucky, you may get stacked wilds, which is when you have an entire playline of wilds – resulting in a profitable payout. You may come across sticky wilds, which stay in the same place on the screen for another turn. Some games have expanded wilds, which look like a normal playline with a wild symbol before the wild symbol takes over (a win), and overlay wilds, a feature of NetEnt games where a wild symbol will ‘take over’ the other reels.


These are another symbol you’ll notice popping up as you play. Each game will have a different scatters logo. Check your games rulebook – because scatters have some surprising functions. They usually trigger another feature of the game, like a bonus spin, or doubling your winnings on a bet. Or, a scatter symbol may act as a wild depending on the game. Usually, three of the scatter symbols located anywhere on your screen will trigger a bonus of some kind.

In-Game Free Spins and Bonus Rounds

While playing you may hit certain combinations that either bring up free in-game spins, or a mini-game. A mini-game basically gives the player more free spins, but shows up as a game within a game. It will go automatically so just watch the screen to see how many free coins you can rack up. A free in-game spin is similarly triggered when you hit a certain combination of symbols. The game will usually tell you that you’ve won a free spin, and automatically use it.


There are several different kinds of rewards you can earn while playing, depending on the rules of the casino. Bonus features are one of the most exciting parts of playing online – you never know what kind of bonus you’ll get, and they’re always different depending on the theme of the game. Here are some common ones to look out for:

  • Bonus spins – Most slots games give out a free bonus spin after you collect a certain amount of coins, and a free spin is a good way to increase your winnings.
  • Bonus games – A lot of games contain a bonus game round that goes with the theme, like a game within a game. A specific set of symbols usually triggers bonus games.
  • Cascades – This is a type of bonus event where a ‘cascade’ of symbols will flow from the top of the screen, replacing other symbols on the playline, acting as a wild, and increasing your chance of success.
  • Free for all – An exciting moment for players when they’re suddenly presented with a time limit to choose a different type of bonus. Sometimes you may choose a free spin or a multiplier bonus.

Try a few rounds on your chosen game to see how the bonuses work. Once you’ve got it down, you can utilize them to win more money.

How to Win at Slots

For a game that’s based on luck, you’ll find a lot of different opinions and methods out there that’ll help you win. It’s smart to go in with some kind of strategy – winning makes it all the more fun after all!

How Online Slots Work

The first step to betting smart is understanding the mechanics of the game. Slots games use an RNG (Random Number Generator) algorithm that determines the outcome of every spin. Each symbol in the slot game is matched with a number, so when the algorithm picks the number, the matching symbol is shown on-screen.

Know the Slots RTP

RTP stands for Return to Player, which is the amount you get from all of your winnings. In most slots games, the RTP is 95%, meaning you get back 95% of what you won. All casinos have a house edge, which is a small amount they take off the top of all winnings. To be able to budget correctly, and compare your profits to your losses, be aware of this little factor.

Betting Systems

Some gamblers swear by them – others see it as a fallacy. As long as you don’t over-rely on these methods, there’s no harm in trying out a betting system. For example, doubling your bets after a loss – the idea is that if you haven’t won in a while, you might win the next turn. Doubling your bet after you’ve lost allows you to recoup your losses and make a small profit. Or you can have a system where you double your bet after winning with the idea that you’ll win again. Check out a few strategies and see if they work for you!

Utilize Free Spins and Bonuses

They’re free! That’s the best reason. Using the free spins and real money offered to you by the casino gives you a chance to make a much larger profit at real money slots, since you’re not spending your own bankroll. Be aware though, the in-game free spins have a lower coin value, but it’s still a free chance to win. Each free spin is worth 10 pennies and may expire within a few days, so it is vital to use them quickly. Check the wagering requirements for bonuses before you play online, but free spins are just that – free.

Manage Your Bankroll

This is the most critical part of the strategy. Only gamble what you can – which means budgeting. Decide how much you want to spend each time you log in. You should also keep in mind how much you’re comfortable losing, and cut yourself off when you’ve reached that amount.

Mistakes to Avoid for First-Time Players

Gambling on the internet is fun and rewarding, but like anything else, there are some pitfalls. Watch out for these common mistakes:

  • Choosing a blacklisted casino – We recommend selecting any of the casinos we’ve mentioned since they’re thoroughly vetted, but if you do decide to find your own, be wary. Double-check that the establishment is not on the list of blacklisted casinos. You could very well lose your money – but this is easy to avoid. Check for licenses, ratings from the BBB, and user reviews. There are hundreds of internet gambling sites operating in the U.S., so don’t let fear put you off. Just stay cautious!
  • Using a “beat the casino” gambling system – While we do list popular betting systems and tips for winning in our guide, we keep things in perspective. Nothing is 100% guaranteed to work, and many dealers themselves will tell you that they don’t believe in betting systems at all. Find a gambling style that works for you, and be wary of anyone advertising a “beat the casino” method – slots are based on luck.
  • Lack of Strategy – Don’t over-rely on real money betting methods, but do go in with a plan to gamble smart. It’s easy to lose track of time and money when you’re playing slots and when you do that, you’re going to lose.

What’s the best way to avoid making these common mistakes? Do your research, read the game rules, and keep track of your bankroll. Play smart, and have fun!

Spinning into the Future

Online gambling will eventually be legalized all throughout the United States, and already, the iGambling industry in America is raking in billions. Everything is getting digitized, along with the casino experience! Internet casinos allow millions of people to gamble – getting to a real casino is difficult and time-consuming! With plenty of significant innovations in the works, providers will continue to create slots games well into the future.
