Where to Play the Best Slots

If we have you raring to play the best slot games out there then here’s where we would suggest you go:

Just make sure you have a little look at the terms and conditions of these offers on site before claiming.

You can Play Slots on Both Bingo and Casino Sites

You have the option to play slots on both bingo sites and casino sites too. There are some advantages and disadvantages to you doing each of these:

Playing on Bingo Sites

When you check out bingo sites UK, many of them will also boast slot games too. These are in place to allow you to have a bit more choice in your gaming time, instead of just getting to play bingo. It gives you some different elements to enjoy within the same site, which makes it last a bit longer.

The slot games can also have a higher return to player and you can play on your own schedule, rather than waiting around for a game to begin. You should be aware that these can be fast ways to lose your money however, so play with caution.

You may find free spins are common on your bingo site of choice, but be aware that the wagering requirements may be different and stricter on these bonuses. Many games also require you to spend real cash to play, so you won’t be able to use those bonuses.

Playing on Casino Sites

There are now lots of casino sites with slots too, which cater to players looking for more intense casino games. These include the likes of table games and specific online casino slots promotions, which can come in handy if you want to play these games.

It’s a pro to be able to take part in these slot specific promotions but bingo players may feel like they miss having these jackpot games in their lobby. For us, it’s better to play on a bingo site because you have that option there if you want it and many bingo sites are rolling out slots based promotions anyway.

Slot Variants

There are many different types of game that you can play within this genre, here are the most common:

Classic slots

These games usually have three reels and look like a fruit machine or puggy. These are the most basic versions of the game, with some of them only having a single payline. The advantage to playing this kind of game is that it’s very simple to set up your bet and start to play.

Cherry Trio, from iSoftBet can be found on Jumpman Slots sites and is an excellent example of a 3 reel game.

Pub slots

This genre of games from Microgaming aim to recreate the pub slots atmosphere. These games are super simple, with just one line but a whopping progressive jackpot. You can play them on Microgaming sites like Glossy Bingo.

Pub Fruity

Video slots

This is quite a generic term for slot games with some graphical elements. Video slots can really be anything with lots of different games falling under this category.

You’ll find the Dracula slot on sites like Top Dog Slots and Big Tease Bingo, it’s a brilliant example of a modern video slot.


Multiline slots

A payline is where you have to match up the symbols within a slot game. These usually pay one way, though you can find games that pay both ways and double up their effectiveness. Multiple lines can be fixed at a set number or flexible to allow you to change your bet.

Most modern slots fit into this category, with plenty of lines for you to win on. One of our fave multiline slots is Jungle Spirit Call of the Wild, which is available to play on the likes of Lucky Admiral.

3D slots

These slots will have a 3D element, whether that’s 3D reels or a character. Over the years, we’ve seen these graphics get so much more sophisticated and interesting. Take games like Fish and Chips as an example, this game clearly has a foreground and watery background – check it out on WTG Bingo.

Fish & Chips

Slots with bonus features

Most of the best online slots these days have some form of bonus feature in there. Generally, this will come in the form of free spins, though there are other ones. They can give you access into an exclusive bonus round, in which you can win bigger and better prizes.

For a game that’s packed full of features, we’d suggest the Asian inspired Koi Princess. It has a total of 8 bonus features, it can be played at Lucky Touch and Lucky Cow Bingo.

Progressive slots

These kind of slots are ones that don’t base the jackpot on what you wager, instead it’s based on what players wager as a whole. A percentage of every wager goes into the prize pot which can be won by any cash player with a minimum bet.

Standalone progressive jackpots are ones that only use the jackpots placed on a single game on a single site. Local area ones would be ones that take into account one game on lots of sites, wider area progressive jackpots can be generated over a number of games and sites.

For ultimate progressive fun, we’d suggest heading to Big Tease Bingo and playing Piggy Payout Jackpot.

Flat top slots

The other kind of jackpot is a flat top one, which will add multiples onto your balance. In these games, the more you wager on the game the more it is possible to win. There are loads of these games out there, but be sure to check out Cheers Bingo for excellent games like the top notch 99 Time.


How to Play Slots for Free on Bingo Sites

If you want to try before you buy then you can even play for free with certain sites to make it easier to find the best online slots UK. You can look for a no deposit slots bonus on many of these sites, through newbie offers or welcome offers. Many sites also now include an element of slots bonuses in their promotions section, so when you want to play slots you can do so with some additional funds.

Can I Win Real Money Playing Free Slots?

When you’re playing slots for free, you may be able to win real money. To do so, you would need to satisfy all the wagering requirements and terms that a site sets out. If you’re simply playing in a demo mode, then you wouldn’t be able to win any money.

Winning Real Money on Slots

To win real money on slot games, you have to be lucky but you can also pay attention to the facts too.

What are the Odds of Winning Online Slots?

The odds of any game are calculated in a number of ways. The number of reels and paylines can affect this, which feeds into the return to player. The return to player is a calculation that takes this into consideration, as well as a number of other factors.

The odds of winning on a progressive jackpot game will be slightly lower too. This is because the jackpot is generated by wagers, so the RTP is lower to allow this to grow. If the jackpot was won more often, then there wouldn’t be as much money in the prize pot.

All of these games use what’s known as a random number generator, or RNG as you may see it on some sites. This means that each symbol is assigned a value and then they will randomly appear when their number is generated. Some symbols have a higher likelihood of appearing than others.

Payouts and RTP

There are so many terms out there that apply to what you can win from a slot and how often you can win. The RTP is one of these terms, which is the opposite of the house edge. This online slots payout percentage basically how often you can win from a game, based on your spend.

Online slots payouts can vary wildly, so by doing your research beforehand, you have the chance to win much more. Looking for the best slots payout percentage, before you choose a game to play will show you just how much they can vary.

Playing Online Slots Safely

Play safely online with slot games by taking the following hints and tips:

Only Play on Licensed Sites

Check out the licencing of a site before you play there. This will be displayed on the homepage of a site generally, though you can check it independently with the Gambling Commission if you’d like to double check.

Paying with PayPal

This alternate payment method is one of the easiest to use to keep your payment methods secure. By creating an account, you can transfer money to and from a site without having to share your details.

Paying with Paysafecard

This one can take a little more effort, as you’ll have to go and buy the voucher for yourself. Then, redeem it online and the money will be transferred into your account. This keeps your card details entirely offline and safe.

Paying by Phone Bill

You can also choose to pay by phone bill, which is super convenient too. This is targeted specifically to mobile users as a quick way to add money to their account. The negative aspect of this payment method is that you can’t withdraw, but it can still come in handy for deposits.

Different Software Providers for Slots

There are a few big names in software that provide their games to a number of sites. The following are some of the most popular:

NetEnt – These developers are characterised by bonus features galore on high quality slots. They have a wide catalogue of games, with the likes of Jimi Hendrix, The Invisible Man and even the Phantom of the Opera making an appearance.

Playtech – The games are old reliables when it comes to playing games online. They’re not quite as sleek as games by other developers but they’re a lot of fun, with big jackpots to boot. It also helps that they have a whole lot of games to pick from.

Playing Slot Games Offline

While slot machines started out as staples of pubs and clubs, this appears to be no longer the case. They’re tending to fall out of vogue with British punters, according to the Financial Times, but you’ll still find them in some pub chains.

Physical casinos are still thriving, as they have become popular destinations for nights out. Their slot games are often the first machines that you encounter when you walk into the casino and as such are very popular. Video slots can be found in many casinos, which allows the user to play with a cabinet but switch the game to their liking, giving a sort of hybrid experience.


So why do we love slots so much? To put it simply, they offer an unparalleled sense of excitement and there are loads of bonuses out there to get playing with too. The design of these games is changing and becoming even more user friendly, with top notch developers leading the way.
