How Slingo Works

Learning how to play Slingo games online is simple. If you have played online bingo or slot games in the past, then you should find the rules easy to pick up! Similar to bingo, each new game will generate a grid, with each box containing a randomly selected number. Place your wager and spin the reels to reveal numbers that can be found on your grid shown on-screen.

To win a ‘Slingo’, tick off an entire row of numbers by spinning the reel. They can be awarded in any direction, be it horizontal, vertical or even diagonal. The more lines you complete, the more cash you’ll win.

If you run out of spins, you can choose to purchase extra spins at the end of the game for a chance to trigger bonus rounds. Some games also feature special symbols or combinations that offer even more chances to win!

Special Symbols

The symbols in these unique games are consistent throughout, and are easy to understand. See below for more information on the symbols:

  • Joker - this can be shown as either a Joker icon or a ‘J’ and essentially acts as a Wild symbol, allowing you to mark off any of the boxes in the column it appears in.

  • Super Joker - choose any number on the entire grid to mark off.

  • Free Spin - receive an additional free spin when this symbol appears.

  • Coin - an instant cash prize becomes available for you to win!

  • Devil - potential matches will be blocked on screen when the Devil symbol appears, so keep an eye out for those!

Landing a minimum of three Jokers or Super Jokers will award an additional instant cash prize.

Five Slingo Tips

If you’re new to the world of Slingo, we have some tips to help you learn about the mechanic.

  • Buy extra spins carefully - Many Slingo slots will offer the option to buy extra spins at the end of the game. If you’re close to completing a Slingo or even a full house (!), this can be tempting. However, sometimes the cost of an extra spin may be more than the value of the prize that you could win, so it’s worth considering whether buying that extra spin would be worth it.

  • Look for bonus rounds - For extra charm, look for games that feature bonus rounds. Although these aren’t always guaranteed to trigger, bonus rounds offer an exciting element to any game and can award potentially lucrative prizes!

  • Use Jokers wisely - Joker Wilds and Super Joker Wilds are common symbols during Slingo. These symbols let you choose a grid position to tick off. Choosing the right position can be difficult since that number could appear in the next spin. It’s recommended to tick off numbers that cover as many vertical, horizontal and diagonal lines as possible.

  • Check the RTP - For players, looking for the best chance of triggering a payout, it’s worth checking the RTP of a game. The Return To Player (RTP) percentage represents the expected payout based on wagers placed in that game. The higher the RTP, the greater the odds of triggering a payout.

  • If you're a beginner, start small - If you haven’t played Slingo many times before, then it may be a good idea to place smaller stakes to begin with, as this will give you the chance to learn and improve your skills.

Why are Slingo games so popular?

The world of Slingo has built a loyal following by successfully bringing together the worlds of online bingo and slots.

Is Slingo similar to bingo?

The words 'Slingo' and 'bingo' are similar enough to hint at a link between the two games! Slingo games are slot machines with a fabulous bingo twist. Like bingo, Slingo uses a grid of random numbers that you can tick off to win prizes.

Spin the reel to reveal numbers that may match the ones on the grid. If you find a matching number, then you’ll be able to tick off that position on the grid! The aim is to tick off an entire row of numbers (either horizontally, vertically or diagonally) to complete a ‘Slingo’. The more Slingos you complete, the further up the pay ladder you will climb!

Who created Slingo?

The Slingo mechanic was invented by Sal Falciglia, a real estate developer from New Jersey, in 1994. Falciglia worked hard to combine elements of a classic slot machine with the popular bingo game. The result? Slingo!

What are the best Slingo games at Rainbow Riches Casino?

We have a wonderful range of games to choose from here at Rainbow Riches Casino. For players looking for the best return on their wager, we include the Return To Player (RTP) percentage on each of our game pages, which explains the expected return is the amount we pay out to players relative to the amount of wagering on the game.

What is the best Slingo strategy?

Just like online slots, Slingo games use a Random Number Generator (RNG), which means the outcome of each spin is completely random.

You can try to mark off positions on the grid based on the number of Slingo lines that they contribute to, but there's no guarantee that the next spin will produce the symbols you need to mark off the rest of that line, so keep that in mind while you’re playing!
