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 classicsMulti-payline and multi-reelVideo slotsProgressive slotsMegaways slots

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.

Multi-payline and multi-reel

Gives you many paylines to work with across multiple sets of reels. You'll usually find multi-reels with 25 or 50 paylines.

Video slots

A computerized version of a classic slot machine, video slots tend to incorporate specific themes, such as themed symbols, as well as bonus games and additional ways to win.

Progressive slots

These are slots connected across a network of sites with thousands of players feeding into a huge jackpot. The winner gets to take home a massive payday.

Megaways slots

BTG revolutionized slots with their Megaways mechanic, developing dynamic reels that offer an ever-changing number of ways to win, where each spin can bring a different combination of symbols across multiple paylines. Set your stake and brace for hundreds of cascading symbols.

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.

  
• 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.

  
• 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.

  
• 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.

  
• 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.

4Pick the right online slots game

Go to the slots section of the casino site and see what they have to offer. There’s always plenty of fun, themed options to choose from. Play for free in a demo mode so you can understand how the game works before playing for money.

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).

We've been the go-to source for casino reviews, industry news, blogs, and game guides since 1995. But it's not just our years of experience that make us trustworthy.

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 choosing games with high RTP or learning bonus-round patterns. Some players also check live results on CasinoScores to get a feel for how certain games behave before playing for real money. Follow these steps to give yourself the best possible chance to win jackpots on slot machines online.
