Online Slingo: Top Games & Casino Picks

Slingo is a brainchild of New Jersey real estate developer, Sal Falciglia Sr., who introduced it to the world in 1994. The name Slingo is a clever fusion of popular casino games – Slots and Bingo (Sl+ingo), the two elements that form the core of the game.

Over the years, Slingo has carved a niche for itself in the UK online gambling industry, with a multitude of UK casino sites now offering the game to their users.

In the broader European online casino arena, Slingo is available on casino websites that host games from software providers like Netent, Pragmatic Play, IGT, SG Digital, Relax Gaming, and Inspired.

Although Slingo might not be the star of the show like online slots, blackjack, or Evolution Gaming’s live European roulette games, it holds its own and is readily available for those who wish to play for real money or simply try it out for free.

Playing Online Slingo Games for Real Money

Slingo games are all about racking up points, and the way to do that is by completing slingos. Imagine a 5×5 grid, much like a bingo card. Your aim is to mark off five numbers in a row, whether that’s horizontally, vertically, or diagonally.

The center square is your key to success, offering four potential ways to score a Slingo: up, down, and across both diagonals.

The points you get for each Slingo can vary, but the rule of thumb is this: the more slingos you complete, the higher your point total climbs. Some Slingo games even offer bonus points for landing on certain symbols or completing specific challenges.

Online Slingo Playing Tips

Below, we share some tips aimed at enhancing your playtime quality for any of the Slingo games listed above. As a rule, these games run on the same principles, making these tips universally applicable.

  • Conceptualize Your Strategy

    Slingo games commonly work on a finite number of spins. Think of these as your strategic arsenal – a tool to be used thoughtfully and sparingly. A hasty match might feel satisfying, but it’s wiser to slow down, survey the game board, and pin down the most beneficial move.

  • Leverage Power-ups

    Power-ups are a unique feature in certain Slingo variations. They’re your secret weapon, capable of eliminating specific numbers from your card or granting you those coveted extra spins. Stash them away for crucial junctures in the game when you need a particular number to complete a Slingo.

  • Aim for Full Slingos

    Your prime target should always be completing a full Slingo, which consists of a line of five numbers. Full Slingos not only yield higher points, but they can also unlock additional bonuses.

  • Target Multiple Slingos

    When faced with a choice between ticking off a number leading to one Slingo or a number at the intersection of two potential Slingos, always opt for the latter. This approach amplifies your chances of securing multiple Slingos in your upcoming spins.

  • Harness Joker Wilds

    In Slingo, the Joker is the wild card, capable of marking off any number in its column. Employ these versatile cards to your advantage, particularly to mark off numbers that culminate in a Slingo.

  • Capitalise on Free Spins and Coins

    Some Slingo versions offer free spins and coins during gameplay. Be vigilant and grab these opportunities—they can prolong your game and accumulate additional points.

  • Comprehend the Game Rules

    Slingo thrives in its diversity, offering several variants, each with its unique gameplay rules and bonus structures. Familiarize yourself with the specifics of the game before you dive in—understanding is the first step towards mastering Slingo.

While the above tips and strategies can enhance your gameplay with each spin – Slingo, at its core, is a game based on Random Number Generation (RNG). This means the outcome of each spin is dictated by chance, not by any specific strategy or decision made by you as the player.

The numbers that appear on your card and the symbols that pop up on the grid are generated randomly, within acceptable boundaries of randomness as determined by casino game testing labs (eCogra, GLI, BMM Testlabs, etc).

Play for sheer entertainment!
