Stick to our list above and you can expect a top-quality gaming experience. Whether you are looking for classic slots such as 3-reel fruit machines or prefer something with more bonus games, these are the places you should sign-up to. New Players are also going to want to snap up some of the welcome bonuses they have on offer. On the other hand, existing players, in particular, high rollers will love the massive jackpots in these casinos.

Players can also rest assured that the above slot sites are all trustworthy. UK players will be pleased to know that most boast a UKGC license. These casinos boast online slot games from top providers. In fact, all of their slot machines are RNG tested and regularly audited by eCOGRA which is an independent third party.

Top Online Slots Casino Bonuses

Our previous list is great if you are looking for the best casinos to win real money playing online slots. If however bonuses are your priority, a few particular ones will come out on top. There are many different bonuses out there. Welcome bonuses or first deposit promotions targetting new players are not uncommon but some are more generous than others.

These can be in the form of free spins awarded on sign up or against a deposit. Some casinos offer similar options for existing players too. One thing with bonuses is that it is essential to read the full terms. Bonus offers are usually not available on all online slots, for instance very few target progressive jackpots. Wagering requirements are also important here. Luckily we have done the hard work for you and taken all of this into consideration. Below are the top online casino bonuses currently out there.

When a casino accepts PayPal, you know they're one to count on. Betfair isn't just ticking boxes when it comes to safety, they also have some great bonuses. Firstly they have a deposit bonus especially for new players from the UK. The casino will award bonus spins on specific slot machines by Playtech. There is a minimum deposit in place but its relatively low. Usually, you'll have to watch out for wagering requirements. This is one of the free spins bonus that does not need you to wager your winnings.

For new customers from other countries, the offer is even better. Again it's a deposit bonus but this time players will need to wager the bonus amount. Players meeting the minimum deposit will also receive free spins. The great thing about this welcome bonus is that it includes some progressive jackpots in its list of eligible games. This is not something you see online casinos doing very often.

If you liked the previous bonus then you'll love what 888 Casino has to offer. Firstly they have two welcome bonuses in place for New Players. Although they are both against a minimum deposit one is a simple 'double your money' bonus whereas is split into 5 tiers. Of course, the latter is a better option if you are looking to win real money but it also comes with bigger risks. The online casino has taken things one step further. They also have a no deposit in place whereby players are awarded free money as soon as they sign-up. Again, they are specific wagering requirements in place and casino games contribute differently to them. The good thing is that all video slots contribute fully and they have a great range if NetEnt slots to wager on such as NetEnt's Berryburst.

Existing players are in for just as sweet a deal. 888 Casino has a bonus for each day of the week. For instance, on Mondays, they have a deposit bonus specifically for progressive jackpot slots. Other bonuses include cashback offers and free play money online. There are many opportunities to reel in a big win and the casino is even helping you get there.


Casumo Casino

  • bonusExcellent loyalty program
Welcome Bonus (RoW)100% up to 300€ + 20 Spins
Bonus Terms and Conditions

If you are a fan of Barcrest slots such as Rainbow Riches, then Casumo is where you want to be heading. The thing about this slot site is that the welcome bonus is subject to change. For what it's worth, they usually offer a mix of bonus money and free spins for new customers making the first deposit. Wagering requirements apply of course and video slots contribute fully.

You may only be able to play selected games when claiming a bonus offer but the library is jam-packed full. If you're a Big Time Gaming fan then you'll be pleased to know that there are loads of Megaways trademarked slots to choose from. Of course, there are hundreds of other slots from top game providers available. IGT's Da Vinci Diamonds and Rumpel Wildspins by Novomatic are some good examples.

New customers from the UK tend to have their own bonus. At times they're lucky enough to receive no deposit bonus spins. What's more, the free spins usually can only be used on the popular 5-reel slots like Starburst.

When it comes to existing players, the online casino is less transparent. We would suggest signing up to their newsletter though as they announce all their deals through this. In our experience, they are constantly updating their special bonus offers.

Traits of a Good Gambling Site

Nowadays, most casino sites look very similar. To many, the end-user is not the slot player exclusively. This is why what you’re looking for might not be available at most casinos. However, there are niche gambling sites that specialise in slots. We can confidently call them slot sites. And as with any other category, some are better than others, and we call them “top slot sites”. Here are the traits that top slot sites have in common.

Casino Game Filters

Game filters, or in specific, slot game filters are taken for granted, and the only time they are appreciated is when they are not available. The option to filter games based on their features, such as bonus games, free spin bonus rounds, multipliers or even the ones that come with a unique feature such as the Avalanche, is probably the best way of exploring new content.

Slot sites, meaning the casinos that put the spotlight on slot games, have more than a thousand slot games. This vast game collection is rarely used to its full potential, but when it is, it’s usually because of the wide array of slot filters available. Just to give you an idea of how diverse game filters can be, here are a few:

  • Free Spins
  • Branded Games
  • Gamble Feature
  • Multipliers
  • New Games
  • Wild Reels
  • Win Both Ways
  • Sticky Wilds
  • Bonus Games
  • Expanding Wilds
  • Re-spins
  • Random Wilds

Not many slot sites offer the full breadth of these filters, yet, even with a handful of these, the gaming experience is significantly improved.

Slot Game Quantity

It’s a common saying that out of quantity comes quality, and we can’t argue with that. It’s one of the reasons why we have so many online casino reviews. Nevertheless, we also have quite a lot of online slot reviews. A big game collection offers you more options to choose from. The filters will get you there, but if there aren’t enough slot games available, the filters can’t help much. Today, there are dozens of online casino game providers, some part of big software groups, others are still trying to breakthrough. Usually, an online casino site will offer games coming from the most popular game providers like NetEnt, Microgaming, Play’n GO and Betsoft Gaming. The top slot sites go above and beyond and include the games of Red Tiger, Yggdrasil Gaming, Pragmatic Play and the full Scientific Games portfolio.

The number of games may vary due to licensing and regulations.

Good Progressive Jackpot Slot Collection

When we say a good progressive jackpot slot offer, we mean the full collection of at least the most popular jackpot games. Betsoft Gaming’s jackpot slots will not suffice. You want access to the record-breaking Mega Fortune and Mega Moolah. You want to be able to play Holmes and the Stolen Stones, but also have access to IGT’s jackpot games like Siberian Storm.

Sure, you can still go back to video slots, and enjoy Reactoonz, Gemix or Book of Dead, but nothing beats the thrill of hunting for a progressive jackpot. Only a small number of slot players have managed to land the jackpot prize, but those that have, are well aware that the patience is worth it. Then again, we have to warn you of the threats of tunnel visioning on a progressive slot. They come with lower than average return to player, which means, they can be a costly “type of entertainment”.

Progressive Jackpot Tracker

Speaking of jackpot slots, if you happen to be a “jackpot hunter”, you will surely like the jackpot trackers online slot sites have to offer. They give you real-time data on what’s the jackpot slot you should go for. However, don’t go blindly into this “competition”, who will get first to the top. If you don ‘t like the game, just don’t play the slot. Nevertheless, it’s good to know where most players are headed. This, in turn, makes the jackpot grow even faster, but because more players are into it, somebody will win the jackpot and win it very soon! It’s basic supply and demand, there’s one jackpot, and thousands of slot players!

Access to Slot Casino Bonuses

We’re not talking about the welcome bonus every new customer is entitled to. Slot bonuses have become a staple, and are a foundation in every VIP and Loyalty Rewards program. Since slot players wager a lot of money (read, play a lot, not deposit a lot), they get to see the most benefit out of these loyalty programs. Then again, even if you’re not a VIP player, you will have access to frequent slot casino bonuses. The top slot sites offer various promotions that target slot players in particular. These may include, but are not limited to, slot tournaments, slot races, random cash drops, which you take part in by playing the qualifying slot games.

Some slot sites go further and offer these bonuses in the promotions page, that are readily available. Nevertheless, check the terms and conditions, looking for a term that prevents players from claiming a bonus on every deposit. This means that you might have to one, two or even three deposits with no bonus before you become eligible for one.

Any information related to the slot games can help you find a game that best suits your preferences. However, the number of online casino sites doing this is going down with every platform update. To some, it’s just another added expense, to others, it’s seen as an opportunity to improve their player service.

The RTP, the problems with the game, the game alternatives, all of these can in some way help you pinpoint the best slot game for you. Note, as we said, they’re extremely rare, so we recommend you to not raise your hopes if this is important to you. Then again, if you do come across a slot site of this kind, you’ve found a hidden jewel.

Online Casino Slot RTP Audit Reports

Security is still an issue, and it will always be. To make players more relaxed, and to reassure them they are playing fair slot games, online casinos hire independent software testing agencies. Moreover, these audits are carried out on a monthly or quarterly basis. This guarantees players like you are getting a fair chance at winning playing slot games. Some of the seals that you want to look for are:

Money Management at Real Money Casinos

As we have mentioned throughout this article slots are addicting. This is even more so for online slots games as they are much easier to access. You won't have to take a trip to Vegas to get a similar gaming experience! Nowadays they are also fully available on mobile to play on the go too. Usually, when we speak about table games and strategy, we look into wagering strategies. When it comes to gambling on slots games - there are none. To top it off, they are one of the hardest games to beat the house. Thus, managing your money during gameplay is essential. 

The biggest advice we can give you is to keep your gaming bankroll separate from your personal one. Gambling on slots can lead to big cashouts especially when playing on jackpots. You can just as easily lose everything in one go. If you do have some money to spare, then make sure you know when to quit. Some games such as progressive jackpots are easy to get hooked on due to their huge pay-outs. The best option is to set a limit and stick to it.

The vibrant colours and state-of-the-art interfaces will reel you in. The in-game bonus features will keep you engaged. But always play at slot sites with some caution. Luckily, there are enough promotions to boost your bonus funds from time to time. 

Slots Sites FAQs

How can I win real money at slot sites?
Unfortunately, there is no way to predict when slots machines will land a win. Of course, we would suggest choosing your game wisely and sticking to reliable slot sites. It will also depend on your personal choice. Slots with low volatility payout more often but with smaller wins. If you are looking for huge payouts then you'll need to stick to jackpots and hope for the best.
Can I play at slot sites via my mobile device?
In most cases yes. At least with any of the top slot sites we have listed you won't have any issues. Most offer a mobile-friendly interface which can be accessed instantly across all devices. Some like bet365 even have an app that you can download on iOS or Android. In either case, you'll have full access to slots games on the go. All you need to do is enter your user name and password and you'll be able to bet with real money.
Is it safe to wager real money at new slot sites?
Not always. Some new slot sites are known to have issues. We suggest checking back to our new casinos' page for a list of sites we recommend. Stick to any of the ones we mention and rest assured that you're in safe hands.
