The UK's Best Slingo Sites 2021

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.

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. 

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 Rainbow Riches

The Rainbow Riches series is a hugely popular collection of online slots created by Barcrest, which turned its attention to developing a related slingo title in 2020. The game has a return to player (RTP) rate of 95.6% and takes place on a 5×5 grid. Bets range from £0.50 to £100. As well as jokers, players can make use of super jokers here to cross off any number on the card. Instead of cutting a player’s score in half, devils will block players from being able to cross off numbers in the column on which the devil has landed. Various bonuses are in play depending on how many vertical and horizontal lines players manage to complete; if they get all ten – known as a full house – they’ll have a shot at the pots of gold bonus and a chance to win 1,000x their stake.

Love Island Slingo

Based on the hit reality TV show, Love Island Slingo has an RTP of 95%, a betting range of £0.10 to £100, and a max jackpot of £5,000. Players will notice the paytable to the left of the 5×5 grid, which can be climbed every time they complete a horizontal, vertical or diagonal line. If the player manages to hit a full house, they’ll win 50x their stake. Free spins, wilds and super wilds are all in play, and if three or more super wilds land on the reels at once, players will receive an instant cash prize.

Slingo Monopoly

Anybody who enjoys the classic Monopoly board game will be pleased with this title, which stays as close as possible to the original. The first thing Slingo Monopoly players must do is select their object, which influences the game’s volatility: choose the dog, for example, and play for a top prize of £5,000; choose the T-Rex, and the max jackpot flexes to £40,000. Instead of a bingo card, players will be presented with the original board, marking off properties as they land on them. Land on a complete set of properties – such as Mayfair and Park Lane – and these will become multipliers. Chance, Community Chest, Go to Jail and Free Parking are all carried over from the board game, and there’s a joker wild that helps players collect properties at a faster pace. With an RTP of 95.3% and a betting range of £0.20 to £25, this is undoubtedly one of the best slingo games around. 

Slingo XXXtreme

We’re back on the traditional 5×5 slingo grid here, with a lava-like background giving this game a fiery feel. Eleven numbers are shot out of the cannon to the side in each round, as well as free spins, wild joker and devil symbols – the latter will act as a block to any potential matches on the card. Players can also land super jokers to cross off any number on the grid, and matching up any three standard jokers in a single spin will be rewarded with a cash prize. Slingo XXXtreme has an RTP of 95%, a betting range of £0.20 to £100, and a max payout of £1,000. 

Slingo Payment Options

The best UK slingo sites will make use of a range of different banking options, each with their own unique benefits. Here are some of the most popular. 

e-Wallets

e-Wallets such as PayPal, Neteller, and Skrill are perhaps the best all-round payment option at gambling sites, with great security, fast deposits, and even faster withdrawals. There’s no need to remember bank details when making a deposit, since transactions can be authorised by linked account information like passwords and email addresses. 

Prepaid Cards

Paysafecard is the leading brand in this space, working on a voucher-based system that can be purchased physically or online. If you’ve purchased your vouchers from a store, you won’t be able to request a withdrawal, but some slingo sites may be able to process withdrawals from those using digital vouchers. These vouchers come with a unique code which will authorise the deposit. 

Pay by Phone Bill

Fancy paying for a deposit using just your mobile phone number? That’s exactly what pay by phone bill services like Boku allow, with the user’s mobile network provider picking up the tab and then charging it to the user’s account at the end of the month. Pay as you go users instead pay with their available credit. Strict limits on deposits and no withdrawal options means this is a payment option to be used alongside another. 

Trustly

Trustly is a bank transfer service popular at UK gambling sites, working as an intermediary between customers and merchants. Trustly availability is limited not only by the casinos that offer it, but also by the banks that support it, so check this information first. 

Visa Fast Funds

If you have a Visa debit card, you can make use of Visa Fast Funds – a system that allows for casino withdrawals to land in a player’s account within 30 minutes. Traditionally, Visa withdrawals can take up to five working days, but Visa Fast Funds has changed the game.
