A devil’s cackle kicks the game off, the electric guitar and drums come in, and the flames around the Slingo Extreme logo give it a loud, full-on look. What sits under the noise is calm and easy to read. A 5×5 grid, 11 spins feeding numbers up from the reel below it, and a prize ladder telling you what each finished line pays. Land a joker, and it is you who picks the number to tick off. Run the 11 spins out, and you decide whether to buy more at a price shown on the spin button before you commit.
The prize ladder runs down the left edge of the reels, 11 rungs from one line up to a full house. Fill a single line and the smallest prize is yours, and each extra Slingo takes you a rung higher, so you can see what the next line pays before it lands. The layout offers 12 lines but only 11 awards, because the final number you match completes at least two lines at once.
At a €1 game, one line pays €0.10, and the full house at the top pays €500, a 500x return for filling all 25 numbers.
A Joker is a clown in a red hat. When one lands on the reel, you choose a number from the column above it, tick it off, and a green star marks the square you claimed.
A Super Joker, dressed in green, reaches further. It lets you mark a number anywhere on the grid, which often makes it the symbol that completes a stubborn line late in the game.
Land 3 or more Jokers or Super Jokers on a single spin, and the Joker Bonus awards an extra cash prize on top of your line wins. The bonus ranges from €0.50 to €5, with only the highest award paid.
Not every symbol is on your side. The Devil, a grinning red cartoon, acts as the game’s blocker and appears only on the centre reel. When it lands, it gives you nothing on that spin, holding the middle in place while the numbers you need stay out of reach. It is the game’s one bit of bad luck given a face.
Coins share that centre reel and do the opposite. A stack of gold coins lands and pays an instant cash amount there and then, with no line to fill first. It is a small, welcome break in the ticking-off, and one of the few prizes that does not come off the ladder.
A gold Free Spin badge adds one more spin to the 11 you begin with, and a game can gather as many as 8 of them. They appear during the main game only, and drop off the reel once you move to bought spins. Any free spins you collect also come out of the pool you could otherwise buy, since no game gives more than 8 extra spins in total.
Once the 11 spins have used the last of the beige balls, the game does not have to end. A fresh set of green balls fills the machine, one for each extra spin on offer. The game shows which prizes are still open, marks the numbers that would complete them in green, and displays the next spin’s price on the button before you pay.
The rules warn that in extra spins, some prizes may need a Super Joker to complete, so a plain Joker alone will not always get you there. The price depends on your position and what is still available, and it can climb well past your game stake as the bigger prizes come into view.
You can collect at any point, while the play controls let you set limits for extra spins, spin price and total spend, ending the game automatically if one is reached.
Set your stake with the green plus and minus buttons, then press Start Game. 11 balls feed numbers up through the reel one spin at a time, each match ticking a number off the 5×5 board and lighting the ladder beside it. A rotating readout over the board cycles the spin number, the spins remaining and the win.
A game runs from €0.20 up to €20.00, whatever you set before the opening spin.
Prize figures reflect a €1 game.

Note that three or more Jokers on a €1.00 spin pay a separate Joker Bonus of €0.50, €2 or €5 for 3, 4 or 5, and the centre-reel Coins drop an instant win whenever they land.
Eleven spins, a prize ladder you can read at a glance, and an extra-spins buy that shows its price before you buy in, that is what Slingo Extreme lays out. The numbers roll, the Jokers help, the Devils get in the way, and the prize moves up a rung at a time. Following it takes no learning, and that is most of why it works. The buy is where a cheap game gets expensive, so the price and loss caps in the play controls are worth setting before you begin.
Slingo has always been part bingo, part slot, and Slingo Extreme keeps that core and adds little else. The 5×5 board sits over a single reel, and across 11 spins, you match the numbers the reel throws up against the ones already on it. Fill rows, columns or diagonals and you move up the ladder.
Where a Slingo like Rainbow Riches or Fowl Play hangs bonus games off that ladder, this one keeps only the plain version, helped by the Jokers that mark a number for you and held up by the Devil that blocks the middle.
For such a simple game, Slingo Extreme makes plenty of noise. A devil’s cackle opens the round, electric guitar and drums play behind the spins, and the flames around the logo and deep red panels push the extreme theme hard. Dings and chimes mark the wins, while the tempo rises as you get closer to the top prizes. It is all surface, though, because beneath the racket the game itself is easygoing and plain to read. The theatre is the loudest thing here, not the play.
The real character of Slingo Extreme is in the buy and in the numbers behind it. On best strategy the RTP is 95%, and every bought spin runs to that same 95%, so nothing about the buy is stacked against you beyond the ordinary house edge. It still adds up fast. Finish the 11 spins short of the prizes you want and the game offers more, but the closer you are to the top prizes, the dearer the next spin, and it steepens quickly.
In our first game, a spin started at €0.39 with several lines open and hit €36.65 once only the full house remained. At that point, the game even stops to ask if you are sure before it takes the money. Its volatility sits on the calmer side, small lines landing often and the full house a rare finish, but a stack of top-priced spins can cost far more than the base game you began.
Our demo for this review showed Slingo Extreme at both its fairest and its most tempting. The first game paid early, with 5 lines from the 11 spins returning €2 from a €1 stake. That was double the money back with no extra spins needed, exactly the kind of steady result the low-medium maths is built around.
We could have collected there. Instead, we took the buy. Spin by spin, the price rose, a sixth line dropped in from a Joker, and the full house stayed two balls out of reach. By the time we stopped, we had put in €90.15 to get €10 back, with the early €2 long since swallowed.
The second game was much slower, ending with just 3 completed Slingo lines for €0.30. With 7 numbers still needed and the next spin already priced at €0.62, we collected and left it there.
Play the 11 spins for what they pay, and the game feels fair. The buy option can make or break a round, with the cost climbing quickly, but it is also the route to prizes the base spins rarely deliver on their own.
