Types of online slot machines and games

There are four main types of slot machines in online gambling. Online slots range from the classic three-reel games based on the very first slot machines to multi-payline and progressive slots that come jam-packed with innovative bonus features and ways to win. Take a look at the slot varieties below for an introduction to each one.

Three reel classics

Old-school slot machines, featuring the usual assortment of aces, lucky horseshoes, and wild symbols. Here you need to line up three matching symbols on a single payline. Just set your coin value and away you go.

Three-reel Classics Slots

How to play online slots - step by step guide

Our step-by-step guide takes you through the process of playing a real money slot game, introducing you to the on-screen options and highlighting the different buttons and their functions.

  • Step 1 - Pick your slot

    Open your preferred online slot machine on your computer or mobile device. The reels and symbols take up the majority of the screen, with the buttons for making and adjusting bets placed prominently, usually at the bottom of the screen. Other information like your balance should also be visible.

    highlighted-base-buttons-on-slot-game.jpg
  • Step 2 - Check the paytable

    Take the opportunity to hit the info button and examine the paytable and symbol values. These should be easily accessible through a pop-up menu that triggers upon touching the info button.

    Highlighted-info-button-paytable-and-symbol-value-on-slot-game.jpg
  • Step 3 - Adjust your bet

    There are multiple ways to do this, depending on the slot. The option you'll find basically everywhere is the one to adjust the value of your wager. Other common options include increasing the number of paylines you are wagering on, or the number of 'coins' you wager per spin, rather than just their value.

    highlighted-bet-adjustment-buttons-on-slot-game.jpg
  • Step 4 - Make your bet and spin the reels

    Once you've set the bet value and payline adjustments to your specifications, it's as simple as hitting the spin button. You can choose the autospin option to avoid extra tapping, though we recommend setting a limit to avoid losing money unnecessarily.

    Highlighted-spin-button-on-slot-game.jpg
  • Step 5 - Wait for the result

    Once the spin is settled, simply hit the spin button again to continue playing. If your spin is a winning spin, your win will be highlighted on the screen.

Top three slots of all time

Starburst

Simple but captivating, Starburst offers frequent wins with two-way paylines and free respins triggered on every wild. The cosmic theme, sound effects, and jewel symbols coalesce into great experience, and players know where they stand at all times. It's the most played slot ever, because it follows the golden rule — Keep it simple.

Best pro: Respins every time a wild lands on screen

Cons: No jackpot

Expert summary: "Pays both ways, free respins, and sticky wilds. You may not win big, but you'll win often."

Starburst
NetEnt

Mega Moolah

Mega Moolah is famous for its massive progressive jackpot, often reaching into the millions. It has an African safari theme with cartoonish animal symbols. The game includes 5 reels and 25 paylines, and its progressive jackpot is randomly triggered, offering players the chance to win one of four progressive jackpots: Mini, Minor, Major, and Mega.

Biggest pro: The record-breaking jackpots

Cons: Without the jackpots, the RTP is only 88.12%

Expert summary: "The graphics feel dated in 2024, but eight-figure jackpots never go out of style."

Mega Moolah
Microgaming

Da Vinci Diamonds

Da Vinci Diamonds boasts a stand-out Renaissance art theme, with Leonardo da Vinci's artworks as symbols and a distinctive Tumbling Reels feature. When winning combinations are formed, the winning symbols disappear, and new ones fall to the screen, potentially creating additional wins from a single spin.

Biggest pro: Watching your wins chain together is super-fun

Cons: It's high variance, which means many players will avoid this great slot

Expert summary: "An all-round classic. I haven't had too many crazy, massive, combinations of tumbling reels over the years, but the extra wins do add up over time."

Da Vinci Diamonds
IGT

The best payout slots in 2024

The payout percentage tells you how much of your money bet will be paid out in winnings. This means you can work out how much you could win on average. For example, if a slot game payout percentage is 98.20%, the casino will on average pay out $98.20 for every $100 wagered. This is also known as Return To Player (RTP).

The following slots are ordered in terms of the highest payout percentage:

Get the best slots bonus

Slots have specific bonuses called free spins, which allow you to play a few rounds without spending your own money. As a new player, online casinos often gift you free spins or a casino bonus as a way to welcome you to the site.

Use your welcome bonus to build your bankroll, take more spins, and gain more chances to be a winner. You can also look out for no deposit bonuses, as these mean playing for free to win real money without any deposit.

TipLook out for casinos with big welcome bonuses and low wagering requirements. Make sure to read through the wagering requirements of all bonuses before signing up.

What are wagering requirements?

Most bonuses for online casino games will have wagering requirements, or playthrough requirements, as one of the key terms and conditions. The wagering requirements represent the number of times you need to wager your bonus funds before you could withdraw them as real money. For example, if you had $50 bonus funds with 10x wagering requirements, you would need to wager a total of $500 (10 x $50) before you could withdraw any bonus funds left in your account.

Slots strategy

Online slots are entirely reliant on chance, but that doesn’t mean there aren’t things you can do to put yourself in a better position to win. The strategy for playing slots tournaments can also vary depending on the specific rules. Experienced players follow a distinct strategy, like only playing games with the highest payout percentages, practicing the bonus round and other bonus features, and knowing their paylines inside and out. Follow these steps to give yourself the best possible chance to win jackpots on slot machines online.

Quick slots strategy tips

Online slots are entirely reliant on chance so unfortunately, there’s no secret strategy to help players win more. However, there are still things you can do to make the most out of every game.

  • Study the paytable

    Before you start playing, have a look at the paytable. Every slot game has its unique symbols and features and the paytable explains how they all work.
  • Go for smaller jackpots

    Opt for games with smaller jackpots, over massive progressive prizes. The allure of a big win is understandable but you're far more likely to be a winner this way.
  • Give the classics a try

    Simpler slot games tend to have a higher payout percentage. Sometimes it's worth sticking with the classic alternatives, even if that brand new video slot looks exciting!
  • Stick to safe sites

    Only play online slots for real money at reputable, trustworthy online casinos. If you're ever in doubt, head to Casino.org to find top-rated sites.
  • Look out for bonus rounds

    Keep your eyes peeled for enticing bonus rounds. This is where you'll find free spins and jackpots and knowing your paylines means knowing your chances of winning.
