Play slots online at Grosvenor Casinos

If you’ve recently registered with Grosvenor Casinos, chances are you’re looking to play slots online. With a simple format and fun features, online slots offer a relaxed, low-pressure gaming experience. There’s a wide range of games to choose from with a variety of themes from ancient Egypt and Lucky Leprechauns to Hollywood movies and TV game shows. Each game has its own instructions, so even if you’ve never played slots online before, you’ll quickly get to understand which symbols to look out for and how paylines work. Many online slots have free spins rounds where you can spin the reels without staking your cash and exciting features that offer you more chances to win cash prizes.


How to play online slots

So, how do you play online slots? Almost all slot games have the same base instructions - simply click the spin button and the game does the rest!

Slot games do not require any skill or strategy. As wins are down to chance, online slots appeal to all levels of player.

Slot game paylines

In order 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 each 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. With these types of games, you can have over 2,000 ways to win.  Megaways games offer even more variety with up to 117,649 ways to win!


Wild and Scatter symbols

Many slots games include Wild symbols, where a special symbol substitutes for all other symbols, helping you create a winning line. For example, if the Wild symbol is a Lion and you have a payline of Giraffe-Lion-Giraffe, the Lion counts as a Giraffe symbol to create a win.

Scatter symbols can also appear at random, with a variety of outcomes. They do not need to be in a payline to be activated. In both Book of Ra Deluxe and Lord of the Ocean, the scatter symbol triggers both the bonus round and counts as Wild, substituting for all other symbols.

But don't worry about this too much – all our online slots are fully automated, so you just have to click the one button to play.


Free spins on slots

As well as being ultra-simple, people like to play online slots for their special features and bonus rounds. Free spins offer an additional way to win without paying, adding excitement and variety to our games.


How free spins work

Free spins can be triggered in many ways. Often, they are achieved by landing a specific set of symbols, but they can also be awarded at random. You can also get free spins by collecting a number of symbols and filling up a ‘free spins meter’ inside the game.

For instance, in Book of Ra Deluxe, if 3 book symbols land on the reels, you’ll be taken to the free spins feature, where 1 symbol is selected to expand across the reels for multiplied wins across 10 free spins. The Lucky Lady’s Charm online slot offers a free spins bonus in a similar manner – 3 crystal balls on the reels will trigger 15 free spins and your stake multiplier will be trebled for the duration of the bonus round.


Online promotions and free spins bonuses

We often give away free spins as part of our slots promotions, so check out the promotions tab to see what’s on offer this week.

How do online slots work?


Online slots work similarly to classic video slots but with the added advantage of being accessible online. Like video slots, online slots use a Random Number Generator (RNG) to ensure that every spin on the slot is fair.

As with both mechanical and video slots, you will need to place a wager. After you’ve placed your bet, you begin to spin the reels. Each spin will possibly reveal a number of winning symbol combinations once the reels have stopped. Each online slot consists of a number of reels, mostly 5. Very rarely do slots have 3 reels, but some can have as many as 6.  

Each game has a set amount of winning combinations to play for, starting with as few as 10 paylines, but reaching as many as 50 or more. The more paylines there are, the greater your chances of winning, although the payouts you receive may not be as high as games with fewer paylines.

Slots like Chilli Con Cash and Eye of Horus offer plenty of opportunities to multiply your money with fun features. Some games even include bonuses like free spins, wilds, scatters, jackpots and other unique in-game features. 

The best way to learn about how online slots work is to play them! Try some of the best slots and games at Grosvenor Casino.

What are Megaways slots?


Megaways slots use a trademarked game formula. This formula uses a unique Random Reel Modifier algorithm to change the number of rows active on each reel with every spin. With every spin, a different number of symbols lands on each reel,  creating even more excitement. This means there are tens of thousands of ways to win, with some Megaways games offering up to 117,694 rewarding combinations. 

Megaways slots are available at Grosvenor Casinos. Sign up and experience the excitement of these unique slots.


How do Free Spins work?


Free spins will vary depending on what game you’re playing, but are generally earned in-game through a special combination of symbols or during mini-games. Most free spins are part of an in-game bonus offering, and using them is exactly the same as spinning the reels during regular play. However, most online games like to highlight when you’re using a free spin so that the player knows they are playing a bonus round.

Join Grosvenor Casinos and play our incredible selection of slots and games, and take advantage of our frequent promotions 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, and can even help complete a winning payline. However, in most online slots, wilds don’t substitute for free spins, scatters or other bonus symbols.

Depending on the game, scatter symbols can appear outside of a winning line but still work as part of a winning combination. This enables wins beyond the typical paylines.

Combinations of wild and scatter symbols are sometimes used to unlock in-game bonuses, but again, this depends on the game that you’re playing.

Looking to try your luck with games that have great wilds and scatter symbols? Join Grosvenor Casinos and play our slots and games for the chance to unlock free spins and more special features.
