Slingo is a hybrid format invented in 1994, combining a slot reel with a bingo-style 5×5 grid. Each spin drops five numbers onto the reel below the grid; any that match grid positions are marked off. Complete five in a row horizontally, vertically, or diagonally and you’ve made a Slingo. Every entry in the series is built on this foundation, with the differences between games coming from what happens when you complete lines, what special symbols land on the reel, and what bonus features unlock along the way. All Slingo games are produced by Gaming Realms under the Slingo Originals brand and are available to play as free demos.
Slingo Classic
Slingo Classic is the purest version of the format. Ten spins, a 5×5 grid, a prize ladder on the side, and no additional mechanics beyond the core. Wild symbols let you mark off any number in their column; Super Wilds mark anywhere on the grid. It’s the reference point for everything else in the catalogue and still the clearest way to understand how the format works before moving to the branded or feature-heavy entries.
Rainbow Riches
Slingo Rainbow Riches is consistently one of the most-played titles in the catalogue, bringing the Rainbow Riches brand into the Slingo format with a Wishing Well bonus picker that unlocks after completing enough lines. Pick from the wells to reveal one of six possible bonus features, including the Cash Crop multiplier game and the Wishing Well trail. The bonus variety gives it replay value that straight prize-ladder Slingo games lack, and the familiar Irish theme has made it a natural entry point for players already comfortable with the original Rainbow Riches slot.
Da Vinci Diamonds
Slingo Da Vinci Diamonds is the Slingo take on IGT’s tumbling-reels slot, running at low-medium volatility with a 5,000x top prize. Complete eight or more Slingos to unlock free spins where a multiplier of up to 10x is applied. It’s one of the lower-variance options in the catalogue, and the Da Vinci art aesthetic gives it a visual identity distinct from the Irish and fruit themes that dominate the rest of the series.
Starburst
Slingo Starburst is the NetEnt crossover, grafting the Starburst slot’s gem symbols and cosmic backdrop onto the standard 5×5 grid. Complete three or more Slingos to unlock the Starburst bonus game, which runs a set of Starburst reels with a guaranteed Win Spin: a specific symbol lands and pays on both sides of the reels, just as in the original slot. The crossover works because the Starburst brand is widely recognised, and unlocking the bonus takes the player out of the Slingo grid entirely and into something that feels like a different game.
Reel King
Slingo Reel King adds Blueprint Gaming’s Reel King character into the format, with a bonus trail that awards five distinct prizes as you complete more lines. Reel King himself appears when the trail triggers, with his trademark spinning head unlocking cash prizes. It’s a straightforward implementation of the format but a popular one, and Blueprint fans who know Reel King from the original will find the crossover comfortable.
Centurion
Slingo Centurion is the Inspired Gaming crossover, bringing Win Spin and Colosseum Trail features into the Slingo grid. Completing lines moves you along the trail, with Roman-themed bonus games at key points. It’s one of the more complex implementations of the format, with more bonus stages than most Slingo titles.
Deal or No Deal
Slingo Deal or No Deal opens with a familiar ritual — pick one of 26 cases, which is set aside while the other 25 fill the 5×5 grid. Spinning the reel opens cases and eliminates prize values from the game. Complete four Slingos to unlock the Banker’s Offer, at which point you choose to Deal (take the offer), No Deal (open your case and collect the prize inside), or Spin (keep playing and receive a fresh offer each spin). A full house reaches a 20x multiplier on whatever prize remains in your case. The three-way decision mechanic is the closest any Slingo game comes to genuine player agency, and it’s why Deal or No Deal remains one of the most-played in the series.
Who Wants to Be a Millionaire
Slingo Who Wants to Be a Millionaire is the record-holder for max win potential in the format at 100,000x your stake. Each Slingo completed reveals a symbol, and collecting three matching symbols wins the associated prize, with the game-logo symbol paying 10,000x at the top end. The 100,000x prize requires a full house in seven spins or fewer, a constraint that makes it the rarest outcome in the catalogue. Nine spins are included per round with the option to buy more, and Joker symbols mark off numbers in the row above where they land. Show-specific music and visual design carry the quiz show atmosphere.
Super Spin
Slingo Super Spin holds the highest RTP in the catalogue at 96.70%, and introduces a sixth reel positioned to the right of the standard five. This extra reel generates additional symbols per spin, increasing the chances of matching grid numbers. The standout symbol is the Gold Disc Super Wild, which marks off any number anywhere on the grid. Music and disco-ball visuals define the aesthetic, and the higher RTP makes it the pragmatic choice for players who prioritise that figure.
Slingo Racing
Slingo Racing replaces the standard prize ladder with a horse-racing track surrounding the grid. Players choose a horse before the game begins, and matching numbers in that horse’s colour moves it around the track. Checkpoints along the route deliver multipliers, with the finish line holding the top prize. It’s one of the most visually distinct entries in the series and the one that most radically reimagines what the Slingo grid surrounds.
Book of Slingo
Book of Slingo is a conventional five-reel slot built under the Slingo brand rather than a Slingo grid game. It follows the Book of Dead template: a Book symbol acts as both wild and scatter, free spins trigger from three books, and a random expanding symbol is chosen at the start of the bonus and covers entire reels when it lands. RTP is 96.38%. It functions as a bridge for players who want to explore the Slingo brand without committing to the grid format.
Slingoooal Championship
Slingoooal Championship puts the grid on a football pitch with stadium surroundings. Wild and Super Wild symbols take the form of football boots and trophies, and landing three of either in a single spin triggers an instant cash prize. Scatter symbols award free spins on a separate slot grid where an expanding Eye of Horus symbol can land. It’s the most football-aligned entry in the catalogue and draws players from that audience who might not otherwise engage with the Slingo format.
