The UK's Best Slingo Sites 2024

What is Slingo?

Slingo is a blend of two popular online gambling verticals: slots and bingo. It was created by New Jersey real estate developer, Sal Falciglia, in 1994, who then founded the company Slingo in order to establish an operational network to distribute the game and develop further variants. The rules around the game will depend on the variant you’re playing, but here’s an overview of how the original plays out:

• Slingo players are presented with a grid of numbers, similar to those you’d find on a bingo card. Separated beneath the grid is a row of individual pockets corresponding to the number of columns in the grid, acting as the game’s only reel. When players spin the reel, these pockets will eventually rest on numbers – if one of these numbers is matched by a number in the grid, that number will be crossed off. 
• To keep things interesting, players need to pay attention to a series of symbols that may or may not appear. In most online slingo games, wilds are represented as jokers, and will cross off any outstanding numbers that remain in the column the wild lands on. 
• There to make life a little harder are the devil symbols, which will cut a player’s score in half when appearing on the reel. Cancelling out the meddling work of the devil symbols are the cherubs, who fire arrows at any devil and reverse its effects.  
• Coins are also regularly included in slingo games, giving points to players. In slingo games involving 20 spins, the final four spins – that is, spins 17, 18, 19 and 20 – tend to be bought using points accrued during the game. Free spins may also land during the round, and these can also be exchanged for one of the game’s final four spins. Time limits are imposed to keep the game ticking along, with players losing their spin if they don’t complete it within the timeframe.

In 2013, Falciglia’s Slingo was sold to RealNetworks for $15.6 million, and the company then passed into the hands of the London-based game developer, Gaming Realms. Slingo has since become a popular gaming option in the UK’s online gambling industry, with 19 different titles available at a host of gambling sites. 

Choosing a Top Slingo Site

There are lots of things to consider before choosing a new slingo site. You’ll want to know which one offers the most generous bonuses, has the biggest range of payment options, and the best selection of games – it’s no mean feat. 

But at TopRatedCasinos, we do the heavy lifting for you, reviewing and organising the best sites into carefully constructed leaderboards. This means our users can find what they’re looking for quickly and easily – here are some of the areas we look at before recommending a slingo site to our users.

Choice of Games

With plenty of different slingo games to choose from, you’ll want to pick a site that hosts your favourites – here are some of the most popular variants. 

Slingo Bonuses

The best slingo sites will offer players a great welcome bonus, following this up with consistent offers to existing players. Here are some of the bonus types you’re likely to find – before making use of any casino bonus, always remember that terms and conditions will apply.

Free Spins

Slingo games incorporate the use of free spins, so free spins bonuses are in play here. These bonuses tend to be given in exchange for a minimum deposit, such as an offer of 20 free spins when depositing £10. If your slingo site doubles up as an online casino, free spins bonuses can be used on the site’s slots library as well as its slingo games. 

Matched Deposits

Matched deposits are frequently used as part of a welcome bonus, where offers can be as generous as 100% up to £200 and beyond. An offer of this size would mean players depositing anything up to £200 will be able to double their account balance, with half of these funds contributed by the casino. Matched deposits for existing members are likely to be less hefty. 

Bonus Codes

Bonus codes can be used to unlock any manner of bonus, whether it’s free spins, a matched deposit, or a free bet. Codes will be redeemable at the cashier page, with the bonus credited to the player’s account as soon as the code is keyed in.
