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;

1. 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.
2. The Super Joker does exactly the same as the Joker, only this time you can pick any box on the grid to tick off.
3. 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. 
4. 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 Centurion Maximus Winnus is one of the most popular Slingo collaborations and takes you back to ancient Rome, complete with chariots, helmets and coins to set the scene. Bonus Levels are called Prizes on Parade, Road to Rome and Reelus Maximus. The overall Return to Player (RTP) % is 95 and the stakes vary from 20p to £25 a spin. Once in  the Bonus round, if you land the Centurion logo, you will multiply your 5-of-a-kind win by a whopping 500x. The game is fully optimised for mobile play, so take this soldier with you.

Slingo Rainbow Riches is a smash-hit collaboration between 2 of the biggest names in the UK online casino world. 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.

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.
