Best Slots Sites for Offers
Grosvenor
Deposit £20, Play with £50
Grosvenor has a great range of offers that you can explore when using their site for slots-based games. They have a brilliant sign-up offer that new customers can look forward to using, and with the bonus funds on offer being a sizeable amount compared to many of their casino-related competitors, you’d be hard-pushed to find better out there.
You can get up to a £700 bonus to use on classic slots when you meet the wagering and qualifying criteria on their site. They’ve got a great range of slots games to choose from as well, so you’ll be spoilt for choice when it comes to choosing the best game for you whilst with Grosvenor. They have jackpot slots, mobile slots, and other casino games that you can access on their slot site, and with this sizeable welcome bonus, you won’t find much better when it comes to online slots sites.
William Hill
William Hill is another bookie that catches the eye when it comes to their offers on slots. They’re offering new customers 100 free spins to use in the casino area of their site, which includes the slot games.
This well-established bookmaker also offers regular slots-based promotions on their site, so it’s important to keep an eye out regularly, as they have plenty to offer both new and existing customers. Their range of online slots is another positive that William Hill customers can look forward to playing as well, as they’ve got many to offer you, and with different stakes available on each of those online slots, there’s something there for customers with varying budgets to use on online casinos.
BetVictor
BetVictor has plenty to shout about when it comes to their welcome bonus, as they’re offering new customers bonus spins to use on their slots games. You’ll be awarded £30 to use on selected slot games on their site, and with 100 free spins also being credited into your account when the qualifying criteria are met, you’ll have a great start to playing on BetVictor’s online slots.
It’s worth remembering that they have wagering requirements that have to be met with the welcome bonus. The bonus funds expire within seven days after being credited into the customer’s account as well, so make sure to use the free spins on offer within that time frame, otherwise, you won’t have another opportunity to obtain this generous welcome bonus from BetVictor. There is also a minimum deposit of £10 to obtain this welcome bonus as well, so make sure you read through the terms and conditions of the welcome offer from BetVictor carefully, whilst also remembering to play responsibly, and within your budgets.
Best Slots Sites for Beginners
Unibet is one of the best slots sites to use for beginners, as they’ve got plenty of useful tools and information that you can use if you’re relatively new to slot games with a bookmaker.
They have beginners’ guides on how to play slots, as well as other articles relating to new players that are looking to get involved in slots games. As well as this, Unibet has a great sign-up offer that you can use as well, as they’re offering new customers £40 to use on their line slots. There aren’t any bonus spins on offer here though, although the bonus funds can be used on online slot games, which makes up for the fact that there aren’t any additional free spins on offer. It’s important to read through the terms and conditions of each welcome offer though, as slot sites have different wagering requirements to meet before a bonus is awarded.
Best Slots Sites for No Wagering
For the majority of offers that you use, you’ll be looking for the ones that have minimal wagering requirements. Otherwise, if you choose an offer that requires you to wager the bonus funds on offer many times, then you could end up losing the majority of your profit before you make a withdrawal. Online casinos can tempt you in with what looks like a great welcome with a sizeable amount of bonus spins on offer, but if you have to wager any potential winnings over 50 times, then you have to question whether the original offer is worth it, especially when you’re wagering some of your own money to meet the qualifying criteria.
Betfred
Stake £10 get up to 200 Free Spins
Betfred is one of the best around when it comes to offers that don’t require any wagering requirement in their casino welcome offer. All you have to do is stake funds of £10 on slots at Betfred Casino, and they’ll award you with 50 free spins to use on Lucky Emeralds or Blue Wizard, followed by another 50 free spins on selected slots games at Betfred Casino.
Their sign-up offer doesn’t require you to wager the bonus spins on offer before making a withdrawal. This makes it the site to use if you’re looking for a slots site that doesn’t require any wagering requirements on their welcome offer.
bet365
New Player Offer at bet365 – Discover bet365 Casino with 100 Free Spins
bet365 has a great welcome bonus that new customers. Bearing in mind there aren’t any wagering requirements involved in the free spins on offer, it’s certainly worth using. There are certain qualifying games that the free spins can be used on, and you must read through the terms and conditions of bet365’s offer, otherwise, you won’t be able to benefit from the bonus spins.
They have an online slots site that is one of the best around, with eye-catching feature images, and a welcome offer that doesn’t require you to wager the free spins a certain amount of times, you’d be foolish not to get involved with bet365 if you’re looking for the best online slots sites out there.
Best Real Money Slots
There are thousands of different real money slots that are available to punters across the country, which will mean that you’re spoilt for choice when it comes to choosing the best game for you. There is likely an additional thrill to playing real money slots, as you can potentially win some money, but it’s hugely important to only wager funds you can afford to lose and to gamble responsibly. Below, we’ve listed some of the best real money slots.
- Age of the Gods – God Of Storms
- Starburst
- King Blitz
- Epic Ape
- Egyptian Emeralds
- Buffalo Blitz
- Lucky Emeralds
- Shamrock Reels
- Kingdoms Rise – Captain’s Treasure
- Storms Of Ice
All of the real money slots listed above have plenty of positives to shout about, from different stakes being available to customers, to the eye-catching images and animations involved in the games. There are also different jackpots available with each game, which is certain to tempt punters into getting involved with them. It’s worth remembering that not all of the games listed above will be available with all slots sites and bookmakers.
Online slot sites will often be looking to provide you with the best range of games when it comes to real money slots, and if they can back that up with a great 1st deposit bonus included in their welcome offers, then that specific operator could be the one for you. If they can offer you free spins to play on some of the best slot games out there too. Then they’re likely to be one of the more popular slot sites to use on a more regular basis if you find yourself enjoying your time playing slot games.
Best Slots Sites for Winning
One thing you should certainly look out for when choosing the best slot game for you with your chosen casino site or bookmaker, is the games payout percentage. This is also known as the RTP (Return to Player).
Return to Player is the amount of money that is paid out per £1 that is wagered. So, if you put £1 into a slot machine with a 95% RTP, then you can expect to get 95p of that £1 back.
However, this isn’t always going to happen of course, as variance comes into play. Otherwise, you’d be having players playing regularly and not losing too much of their budget. Slots sites will be looking to make money themselves, so variance always comes into play. Players can win potentially sizeable amounts of money on slot sites if they’re lucky enough, but they can also lose hefty amounts if they don’t gamble responsibly.
As a player, you’re going to want to look out for online slots that have the highest RTP out there, as the higher the RTP is, the more regularly that funds will be paid out back to the player of the slot games.
However, it is worth noting that some slot games with a lower RTP aren’t necessarily poor games to play, as they could have a different style compared to some online slot games that have a higher RTP.
Playing online slots can be fun if you bet within your limits, but it’s important that you remember to play responsibly, and seek relevant help if you ever find your gambling habits are getting out of hand. You should also keep in mind that there aren’t ever any guarantees that you’ll win money whilst using any of the gambling sites in the UK, and we can only emphasise the importance of reading through the terms and conditions of each offer that is promoted on our site, as well as taking into account the best slot sites that are suited to you.
