What started out as an interesting new concept from the former real estate developer, Sal Falciglia, back in 1994, has slowly grown into an incredibly popular game genre in its own right over the decades. Some 20 years after its inception in New Jersey, the Slingo brand finally crossed over the pond and made the UK its new home under its new parent company, Gaming Realms.
Slingo games sites work just like regular online casinos, and the game itself has a mix of bingo and slot features. For example, you’ll find a 5×5 square layout with numbers, but there can also be different symbols, like with slots. At the bottom, there is also a typical slot reel, and you have to spin to get the next set of numbers and symbols – they won’t appear automatically like in bingo.
We describe a few of the most detectable advantages of using Slingo sites over regular bingo ones below.
There are 12 versions of the game that were originally developed by Gaming Realms and are now known as Slingo Originals. Each one has a unique set of features and different themes, and this variety is one of the reasons so many people are drawn to Slingo sites.
From the more subdued classic layouts to more interactive variants, and all the way to designs inspired by iconic movies and TV shows and many other themes from pop culture.
Apart from the standard gameplay, you can also find special symbols like a Joker, Wild, Blocker, and Free Spin. There is also a Cash Prize symbol that leads to an instant payoff and a Super Joker that can fill any position on the board.
Slingo Adventure games also have specific Power-Ups that change things up by adding score multipliers, stealing half of your points, providing bonus points, increasing the odds of certain symbols appearing, or offering extra spins. These make the game much more dynamic and draw lots of new players to online slingo sites.
As you can see, Slingo doesn’t rely on a simple gimmick just to be different, and there are plenty of interesting features you won’t find anywhere else. With that in mind, let’s go over some of the important details about the game and the sites that offer it.
Before we move on to the gameplay and the different versions, we have to talk about a few things you need to consider when browsing through the top Slingo sites in Great Britain.
On some sites, Slingo games may not contribute 100% towards the wagering requirements like slots do. They may, instead, have them at 20%, just above Blackjack, which sits at 10–20%. That way, only £20 for every £100 you wager will contribute toward the required amount to clear the bonus.
As the number of free spins you get at the start can be as low as 10 or 11, it is quite tempting to try and get a few extra ones. The problem is that the prices tend to shoot up with every additional spin, and it’s easy to forget how many times you’ve already paid for this little extra boost. Most of the time, it simply isn’t worth it.
It may seem that all these games are fairly similar because they all have Slingo in the title, but there is an incredibly wide range of RTP rates and varying levels of volatility, just like with slots. Always research a new game to find out how it plays and look for those that fit your preferred budget, pace, and playstyle.
Slots players who enjoy faster-paced games with higher bets and riskier strategies come into Slingo expecting that they will do the same. However, while the allowed bets for slot games range from under £1 all the way up to £50 or even £100, for most Slingo games, the range is from 10p to £15, sometimes up to £25. This also makes it more difficult to clear higher wagering requirements.
With all the little insights into the industry wrapped up, it’s now time to share how we rate Slingo bingo sites and what it takes to make it onto our list.
When researching bingo sites with Slingo, our team first makes sure that they have a UKGC licence and that they accept a variety of common payment methods for both deposit and withdrawal. We then move on to another important part – how the player likes the site overall. We cover these main points:

Slingo combines classic bingo rules with slot-style spins, but it has a few twists that make it more dynamic than it looks. Here’s a breakdown of how the gameplay works, including the symbols, grid layout, and a few tips worth knowing before you dive in.
You play on a standard 5×5 bingo ticket grid, with 75 balls in play, but there is also a 5-reel slot wheel at the bottom. Each reel will have a group of numbers, for example:
However, there are also the additional symbols that we mentioned earlier:
You get a set number of spins at the beginning, most commonly 11, but it can be any number from 10 to 20, depending on the game, as different Slingo game sites will have different defaults. In each spin, you will get five random numbers, or several numbers and a symbol or two, and you can then match any of the corresponding ones to those on the grid.
The goal is to fill out the entire card, but the game will also end if you use up all your spins or don’t have enough points for the Final Spins (the last four). Some games also let you cash out at any point during the last few spins.
Whenever you get a complete line, in whichever direction, on the board, you get progressively higher rewards. There is a ladder showing the increased reward based on the number of lines on the left side of the screen in most versions.
Regardless of the game variation you play, you have the greatest chance of getting a Slingo with the squares in the corners and the middle, so the best strategy is to place the markers you get from Jokers and Wilds, and their Super variations, in these spots.

As sites with Slingo often run various promotions, it’s easy to get started with a fairly small deposit and get through quite a few games, to see how everything works.
The most common types of offers are a deposit match bingo welcome bonus and free spins. Slingo sites no deposit promotions are rare, but can pop up. You can also try out some of the demo Slingo sites if you want to test out the mechanics before playing with real money.
We hope that you now have a better understanding of the basic Slingo rules and strategies, but we also need to look at the most popular versions you can find online.
Our team has looked at all the popular Slingo casino sites to find the games that offer a reasonable chance of winning, have all the right features, and are simply fun to play. These are often themed after popular TV shows like Deadliest Catch, Deal or No Deal, or Shark Week; classic slots like Cleopatra or Rainbow Riches; and even different board games, books, and other popular media.
Slingo Originals offers some of the best titles with themes ranging from quirky to classic slot-inspired. Here are a few of our top pics:
These are all good choices for anyone who wants to get a feel for this style of game, as they have all the basic mechanics, interesting visuals, and relatively high RTPs. You can take your time and try out a few different options to find a game that really works for you, but before you do that, we have some important parting words.
