Each time you play slots, you'll find that each game has its own instructions. So even if you’ve never played online slots before, you’ll quickly get to understand which symbols to look out for and how paylines work. Many have free spins rounds where you can spin the reels without staking your cash, plus exciting features that offer you more chances to win cash prizes. 


Almost all slots have the same base instructions - simply click the spin button and the game does the rest! Playing online slots doesn’t require any skill or strategy. As wins are down to chance, they appeal to everyone.

The basic rules of winning are to line three or more matching symbols along a payline. A win is awarded based on the paytable and the value of the symbols – the higher the value of the symbols and the more you get in a row, the more you win. You’ll also find that online slots come with plenty of features to increase the thrill and the prizes. Many also have incredible graphic animations for fully immersive gameplay!


Slots come with various components that come together to form the machine we all know and love. Each of these elements plays a specific role in the gameplay, which ultimately, is meant for your entertainment or to bring you some prizes. The following covers the most common ones to expect in an online slot game.  


To win, you need to match identical symbols in a specific order on the reels. This is called a payline or a win line. Each game will have a different number of paylines. You can see what these are on the in-game help menu. Paylines are often: 

-        In a row

-        In a zig-zag pattern

-        In a V shape

-        Diagonally

The winning symbols for each game vary, and paylines are weighted differently on each spin. When you are playing with real money, your balance will be debited every time you spin the reels. You will also need to decide how much to stake on each payline to make up your total stake. 

Some slots do not use paylines and instead payout based on the number of symbols you land on the reels. Common examples are the Cascading Reels game engine and the Cluster Pays game engine.   

Grosvenor Pro Tip: Megaways Slots offer the highest number of ways to win, with some reaching up to 117,649 ways! That’s 117,649 chances of winning!! 


As well as being ultra-simple, people like to play slots for their special features and bonus rounds. Free spins, Prize pickers, Jackpot rounds and many more are some additional ways to win, adding excitement and variety to our games. Here are some common features to expect:


A Wild symbol can fill in for any other symbol on the reels by chipping in for the missing symbol in a combo. They typically don’t substitute for Free Spins, Scatters or other bonus symbols. Scatters and Bonus symbols are mostly in place to unlock in-game bonuses, but this differs with each online slot.  


A feature made popular through NetEnt’s Starburst slot. The bonus is activated at random or when you land a special symbol. The reels undergo a re-spin for free, in an attempt to give you another win that can improve the payouts! Re-spins can be accompanied by Sticky Symbols or Sticky Wilds, which are locked on the reels for the re-spin to further improve the wins. 


The most common way to trigger Free Spins features is by getting several Scatters. Free Spins are granted based on the number of Scatters used to trigger the bonus. This bonus does not count on your stakes, which means you will reap prizes for free! Some extra rewards and bonuses can be included in the Free Spins rounds of certain slots online. 


Simple as they sound! This bonus round is usually triggered through bonus symbols and the general rule is to select symbols on the screen to claim a prize. Slots can go the extra mile to offer access to additional features through the Prize Picker round… even Jackpots! 


Not all online slots trigger a Jackpot straightaway! To spice things up, a Jackpot round is included which comes in the form of a Wheel of Fortune or a prize picker round. The aim? To award you the jackpot if you manage to land on the luckiest prize of the round. Blueprint Gaming slots are well known for their thrilling Jackpot rounds! 


At Grosvenor Casinos, we have a large variety of Jackpot slot games that propose Fixed and Progressive Jackpots and also pay in real cash. 

Fixed Jackpots are simple. They have a fixed amount that is awarded to the player when triggered. As for Progressive Jackpots, they increase each time you wager on the slot. Some popular types of Progressive Jackpots include the Must-Go Jackpot, Daily Jackpot, and Mega Jackpots! 


At Grosvenor Casino, we often give away Free Spins as part of our promotions, so check out the promotions tab to see what’s on offer this week. 

If you’re new to slots and can’t decide which slot game to choose, take a look at our range of bonus offers, including our welcome bonus when you join Grosvenor Casinos online. 

Your Welcome Bonus is valid on your first deposit only. T&Cs apply. Once you’ve deposited, you’ll get extra funds to play on a selection of slot games. 




How do online slots work? 

Online slots work in a similar fashion to classic casino slots. Each spin will activate a number of reels, revealing potentially winning symbol combinations once they’ve stopped spinning. Each online slot consists of a number of reels, with a set number of winning combinations to play for. Some games even include bonuses like Free Spins, Wilds, Scatters, Jackpots and other unique in-game features.  

What are the most popular online slot games? 

The most popular online slots include many in-casino classics, such as Rainbow Riches, Cleopatra and Book of Ra. Our Grosvenor Original game, Buffalo Wild, has proved an instant classic and has already made it to fan-favourite status. Check out our full Top 20 list for more inspiration.  

What are Megaways slots? 

Megaways is a trademarked game formula that uses a unique Random Reel Modifier algorithm to change the number of rows active on each reel with every spin. This means potentially more winning combinations are in play with every spin. Some Megaways games offer up to 117,694 ways to win.  

How do Free Spins work? 

The nature of Free Spins will likely vary depending on the game you’re playing, and if you’ve earned them in-game or through a promotion. Most online slots feature Free Spins as part of an in-game bonus offering, and using Free Spins is as simple as spinning the reels during regular play. Online slots usually like to highlight when you’re using a Free Spin. You’ll also find frequent promotions on offer with Grosvenor Casinos where Free Spins are up for grabs.  

What are Wilds and Scatter Symbols on slots? 

A Wild symbol can fill in for any other symbol on the reels. A Wild can be adapted to complete a winning payline. Wilds typically don’t substitute for Free Spins, Scatters or other bonus symbols. Scatter symbols can appear outside of a winning line, but still register as part of a winning combination. This enables wins beyond the typical win lines. Combinations of Wild and Scatter symbols are sometimes used to unlock in-game bonuses, but this differs with each online slot. 

Can I play slots on my mobile? 

You can play slots online via mobile using a smartphone or table. Play via your internet browser or download our free Grosvenor Casinos app, available for both Android and iOS devices.
