The Best Slingo Games at Online Casinos in 2025  

Though created in 1994, Slingo has only recently become popular at online casinos in the United Kingdom. This fun, fast-paced casino game shares elements of slot machines and classic bingo, offering big potential wins, bonus features, and lots of excitement.  

So, with Slingo riding the crest of a wave and many classic slots having a Slingo makeover, which are the best games, and where can you play them online in the UK?  

Here, we reveal everything you need to know about Slingo, including the top UK online casinos stocking dozens of games.  

What is Slingo?  

Slingo is the mash-up you didn’t realise you needed. As the name suggests, this game combines slot machine and bingo gameplay.  

Most Slingo games feature a 5×5 grid with a set of reels below. The aim of the game is to match numbers on the reel with those on the grid. If you’re successful, you will win a payout.  

Sal Falciglia is credited with creating the game in 1994, but it has come a long way since then and now dominates the game offerings at many online casinos in the UK.  

Slingo is so popular today that many top studios have released Slingo iterations of their most popular slots. Case in point – Gaming Realms have remastered Slingo Cleopatra by IGT and Slingo Starburst by NetEnt in this new and exciting format. 

Slingo Gameplay Explained  

For first-time players, Slingo can be a little confusing. Essentially, there are two components – the bingo card and the slot reel at the bottom of the screen.  

Your wager per game will give you a specific number of reel spins (often 10). Then, any time a number on the reel lands, it will be chalked off on the bingo grid.  

If you make a line, you will receive one ‘Slingo’. The more lines and Slingos you receive, the better the prize will be, plus some games will trigger a bonus round. In most games, you must receive at least three Slingos to play for bonus prizes. 

At the end of your spins, you can often spin the reels again for an additional wager to help you land a win.  

Many Slingo games come with special symbols like wilds, which give you the choice of which square to dab. You may also receive free spins to add to your tally and other special features.  

How to Play Slingo: Step by Step Online Guide  

One of the reasons for Slingo’s popularity at UK casinos is that it’s so easy to play. Though every game is slightly different, here are the steps you need to follow to get started:  

Step 1: Choose a Slingo game  

Browse the game offering at your chosen online casino and decide which Slingo game to play. You can search via theme or use RTP as your base metric, ideally selecting a game with an RTP of 96% or higher.  

Step 2: Read the game rules  

Like every slot machine, every Slingo game is slightly different. So, read the game rules, find out how to make Slingo lines, and discover the special symbols. You should also check how many spins you receive per wager (often 10). Finally, check how to access any bonus round before playing so you know what’s happening.  

Step 3: Adjust your stake and slingo strategy 

Next, decide how much you would like to bet per game. To do this, use the plus and minus buttons next to the spin button until you’re happy with your wager. Please remember to gamble responsibly and only ever bet what you can afford to lose.  

Step 4: Click the spin button  

Click the spin button and watch the game unfold. As the game progresses, you will be required to choose squares at specific intervals to try and make lines or a full house.  

Step 5: Collect or spin again  

The final step is to collect your winnings or elect to pay for another spin. If you continue spinning, you can gain access to better rounds. But be careful, this can get expensive quickly with no guarantee of winning.
