Slingo Sites: What Slingo Is and Who Has It
Slingo is what you get if you take a 75-ball bingo card, bolt a slot reel underneath it, and let the two argue for about five minutes. It's genuinely its own thing — not bingo with slot graphics, not a slot with numbers on — and once it clicks, a lot of bingo players find it hard to go back.
This page explains what Slingo actually is, where it came from, and which of the UK bingo sites we've reviewed carry it. It also tells you plainly what we haven't covered yet, because pretending otherwise would be no use to you.
What Slingo is
A Slingo game gives you a 5×5 grid of numbers — the same grid shape as a 75-ball bingo card — and a single reel that sits beneath it. Each spin turns up a handful of numbers. Any that appear on your grid get marked off.
Complete a line, in any direction, and you've made a "Slingo". Complete more of them and you climb a prize ladder printed alongside the grid. You get a set number of spins to do it in, and when they run out you can usually buy extra spins using the winnings you've accumulated — at a price that rises the further up the ladder you are, which is the decision the whole game turns on.
The reel also carries symbols rather than just numbers. Jokers let you mark off a number of your choosing from the column above; the more generous versions let you pick anywhere on the grid. Working against you are blocking symbols that waste a spin entirely. That mix — a bingo card you're steadily filling, a slot reel deciding whether you fill it, and a running decision about whether to buy another go — is what makes Slingo feel different from either parent.
Where it came from
Slingo was invented in 1994 by Sal Falciglia in New Jersey, originally pitched as a television game show format that mashed bingo together with a slot machine. The first playable version launched on AOL in 1996 and became a genuine hit of early online gaming, and by 1999 IGT had built a physical Vegas slot machine around the same mechanic.
The modern chapter starts in 2015, when the British company Gaming Realms acquired it. Gaming Realms develops the Slingo Originals catalogue and licenses the format to operators, which is why the Slingo games you'll meet at UK sites are usually branded versions of familiar titles — the Slingo treatment of a well-known slot rather than an unrelated game.
Slingo versus bingo versus slots
Worth being clear about what you're actually choosing between, because the three play nothing alike.
Bingo is communal and passive. You buy tickets, the numbers come, the software marks them, and you're playing against everyone else in the room for a shared pot. The pace is set by the room, and the chat is half the point. Our guide to 90-ball and 75-ball bingo covers how the formats differ.
Slots are solitary and instant. You set a stake, you spin, you find out immediately, and nothing carries between spins.
Slingo sits between them. It's solitary like a slot, but it has the shape of a bingo game — a card that fills up, progress that accumulates, a target you're working toward across a whole session rather than one spin. And unlike either, it asks you to make a judgement call at the end about whether to buy more spins. That decision is where the game lives, and it's also where it's easiest to spend more than you meant to, so set your limit before you start rather than in the middle of a good run.
Which sites we've reviewed carry Slingo
Here's the honest picture from the sites we've actually checked, rather than a list copied from press releases.
Mirror Bingo is the clearest of the lot. It names its Slingo titles rather than gesturing vaguely at the category — Slingo Rainbow Riches, Slingo Riches and Slingo Extreme when we checked — and it gives the best plain-English description of what Slingo is that we found on any UK bingo site.
888 Ladies carries Slingo as a proper category alongside classic slots, Megaways and progressive jackpots, rather than burying it. Of the Broadway Gaming brands we reviewed, it's the one that treats Slingo as something a bingo player might actually want.
MrQ lists Slingo alongside its slots, live casino and 90-ball bingo. It's also the site in our comparison with the most distinctive approach to bonus terms, which is worth reading up on separately.
The Jumpman platform brands — a very large family of UK bingo sites — carry Slingo consistently but thinly. Across the brands we checked, the selection ran to a handful of titles rather than a full range. It's enough for an occasional change of pace, not enough to be the reason you join. Our guide to Jumpman bingo sites explains what that platform shares across its brands.
What we haven't covered yet
We have not reviewed a dedicated Slingo-led operator — a site built primarily around the format with the full catalogue behind it. Several exist. We haven't been through their terms, payments and withdrawal processes to the standard we apply to everything else on this site, so we're not going to recommend one.
Nor do we publish RTP or volatility figures for individual Slingo titles. Those numbers should come from the game provider's own information, with a date attached, and we'd rather print nothing than print something we can't stand behind. The information screen inside any game will give you its published return figure.
If you want Slingo as a sideline to your bingo, the sites above cover it and we can tell you how they behave. If you want Slingo as the main event, wait for us to do the work properly.
What to check before you play Slingo
- How many base spins you get, and what buying extras costs as you climb — the price escalates, and the last few spins are the expensive ones.
- What the blocking symbols do, since some versions are considerably harsher than others.
- Whether it counts towards bonus wagering. This catches people out constantly. Sites weight game types differently when you're clearing a bonus, and Slingo doesn't always count the way slots do. Check the weighting table in the bonus terms first — we've explained how that works in what free spins on bingo sites really mean.
- The game's own information screen, for its published return figure and paytable.
- Your limit, decided before the buy-more-spins prompt appears rather than after.
Frequently asked questions
What is Slingo?
A game combining a 5×5 bingo grid with a slot reel. Spins reveal numbers, matching numbers are marked off your grid, and completing lines moves you up a prize ladder within a limited number of spins.
Is Slingo bingo or slots?
Neither, properly. It borrows the 75-ball bingo grid and the reel mechanic from slots, but you play it alone against a prize ladder rather than against a room, and progress accumulates across spins in a way slots don't.
Who invented Slingo?
Sal Falciglia created it in New Jersey in 1994. It launched on AOL in 1996, reached Vegas slot machines via IGT in 1999, and was acquired by the British company Gaming Realms in 2015, which now develops the Slingo Originals range.
Which UK bingo sites have Slingo?
Of the sites we've reviewed, Mirror Bingo names a small named selection, 888 Ladies carries it as a full category, and MrQ lists it alongside its slots and bingo. Brands on the Jumpman platform carry it thinly. We haven't yet reviewed a dedicated Slingo-led operator.
Can you play Slingo for free?
Many Slingo titles offer a demo mode with play money, which is the sensible way to learn the mechanic before staking anything. Demo play won't tell you anything about real outcomes, but it will teach you what the symbols do.
Does Slingo count towards wagering requirements?
Not always, and not always at full value. Game weighting varies between sites, and Slingo is often treated differently from slots. Always check the weighting table in the bonus terms before you start playing through a bonus.
Is Slingo fair?
On a UK-licensed site, Slingo outcomes come from a tested random number generator under the same technical standards as any other game. We've set out how that testing regime works in is online bingo fixed?
Where to start
If you've never played it, start in a demo, learn what the Jokers and blockers do, and get a feel for how quickly the extra-spin prices climb. Then play it somewhere you already trust for the other things that matter — payments, withdrawal times and support — which is what our best bingo sites comparison is actually for.
