How to Play Slingo

The game is based round a 5×5 grid and the idea is to collect numbers and complete the lines of the grid. The lines are called Slingos and they can be in any direction; horizontally, vertically or diagonal. There are a total of 12 lines and most Slingo games offer a minimum payout at 5 completed lines. So, the more completed lines there are, the bigger the win.

There are also a series of bonus features to add further spice to the game, including Jokers, Super Jokers and Free Spins. At the side of the grid is the bag of balls containing the numbers and they empty with each spin.

Types of Slingo Games

With such a straight-forward but exciting design, Slingo lends itself to a range of slot games and themes. One of the most notable features of all Slingo games are the Bonus Features. These include;

The Joker randomly sits on a reel and allows you to tick off an extra number in any box that lies next to the Joker.
The Super Joker does exactly the same as the Joker, only this time you can pick any box on the grid to tick off.
The Devil, to give him his due, is one to avoid! This feature will block any win on the line that he lands on. Get thee behind me Satan.
Free Spin is self-explanatory and gives you an extra chance to land that big win.

TOP Slingo Slots for Real Money

Beyond these features, most games also have a series of Bonus Rounds that can enhance and multiply wins. Good examples of online slingo games and slots include:

Slingo Money Train from 2025 merges the Slingo mechanic with the hit slot series, delivering high volatility and a maximum win of up to 10,000x. The RTP is around 94.5%, with stakes ranging from 20p to £100 per spin. Special features include Bronze, Silver and Gold Bonus Wheels leading into the Money Train bonus round, where modifiers such as Payer, Collector and Sniper can boost cash values significantly. This is one of the most feature-rich Slingo titles and fully optimised for mobile.

Slingo Deal or No Deal game from 2025 brings the iconic TV show to the Slingo grid, combining number matching with the banker’s offer mechanic. The RTP sits at around 95%, and the volatility is medium to high. Once you achieve four Slingos, the banker begins making offers as you eliminate boxes — just like the show. Jokers and Devils serve as wilds and blockers, and Free Spins symbols can extend gameplay. Extra spins can also be purchased mid-round, adding an extra layer of strategy to this real-money Slingo experience.

Slingo Monopoly is another winning marriage between legendary names, this time the classic property-based board game. You start the game by selecting the size of your deposit and then proceed with the 11 spins, possibly more if you land a Free Spin Bonus. The symbols are the same as the game, so you can select the Dog, the Car and so on. Each one comes with a different number of spins and volatility. There are also Community Chest and Chance cards. Slingo Monopoly looks different to other iterations, as it is based round the board, letting you buy and collect properties as you go round. Just trying and avoid landing on “Go to Jail”! Come to rest on Free Parking and you scoop the pot.

Punters will be familiar with the luck-of-the-Irish theme that has made Rainbow Riches such a hit and it combines superbly with the Slingo set-up. With a 95.6% RTP, Slingo Rainbow Riches comes in just below average. The Bonus Levels include Wishing Well, Cash Crop (50 spinning coins revealing random wins), Mega Toadstool and the Pots of Gold feature, with the chance to win the 1,000x multiplier.
