How to Play Slingo: A Beginner’s Guide to Rules and Gameplay

Slingo combines slots and bingo on a 5×5 number grid with a set of reels beneath it.

Spin the reels, match the numbers they reveal to your grid, and complete full lines – called Slingos – across rows, columns or diagonals to climb the prize ladder within your allotted spins.

If you’ve come across Slingo bingo and want to know how it works, you’re in the right place. It’s one of those games that’s easy to pick up once you understand the core idea: part bingo card, part slot machine, with its own prize structure that makes every spin mean something.

This guide covers the Slingo rules, symbols and tips you need to get started, plus the Slingo games available at William Hill Vegas.

What is Slingo?

Slingo is a hybrid game that blends bingo-style number marking with slot-style reel spins. It first appeared in the 1990s, and the modern online format was shaped largely by the Slingo Originals range, developed by Gaming Realms. Understanding how Slingo works comes down to one mechanic: spin the reels, match the numbers, complete lines.

How to Play Slingo Step by Step

1. Place your stake to set the number of spins you receive.
2. Spin the reels beneath the 5×5 grid.
3. Any reel number that matches a number in the column above is marked off your card.
4. Complete a full line – horizontal, vertical or diagonal – to score a Slingo.
5. Keep completing Slingos to climb the prize ladder.
6. When your spins end, collect your prize or buy an extra spin if you want to continue.

There are 12 possible lines in total: 5 rows, 5 columns and 2 diagonals. If you clear all 25 squares, that’s a Full House.

Slingo Symbols Explained

• Joker: marks off any number in the reel’s own column.
• Super Joker: marks off any number anywhere on the grid.
• Free Spin: awards an extra spin without using one from your allocation.
• Coin / cash prize: awards an instant prize.
• Devil / blocker: blocks a column for that spin. Features vary by title.

The Prize Ladder and Buying Extra Spins

Every Slingo game features a prize ladder running alongside the grid. It starts at the bottom and moves upward each time you complete a line. The higher you climb, the larger the prize value at that stage, so the ladder gives you a running indicator of where you stand as the game progresses.

This is part of what makes Slingo feel different from standard slot machines. Instead of waiting on a single spin result, your position on the ladder builds across the whole session as you accumulate Slingos. A Full House (clearing all 25 squares) typically sits at or near the top of the ladder and represents the game’s biggest payout.

When your spins run out, you typically get the option to collect your current prize or buy an extra spin to keep going. That’s an optional decision, and it’s best treated as a game feature rather than a way to chase a better result.

Slingo Tips for Beginners

Slingo is a luck-based game, so no tip can change the outcome of a spin. If you want to know how to win at Slingo, the honest answer is that outcomes depend on the reels, but understanding the grid helps you get more from each spin.

The centre square can contribute to four different lines at once. Rows, columns and both diagonals all pass through it. Corner and diagonal squares also cover multiple lines, so they’re more valuable than they might first appear.

Beyond that, the best approach is to stay comfortable with your stake, keep an eye on the card, not the spin animation, and treat the buy-a-spin option as a choice, not as a shortcut to a win.

Slingo Games to Play at William Hill Vegas

William Hill Vegas offers a range of Slingo titles, from the original format to themed variants with their own mechanics. Here are four to start with.

Slingo Classic

Slingo Classic is the original, no-frills version. A good starting point for learning the core format without distractions. It keeps the 5×5 grid, standard symbols and prize ladder in their purest form, with no extra bonus rounds to navigate. It has medium volatility, and a Full House pays 500x your stake. Check the game’s information screen to confirm the current figures before you play.

Slingo Originals

Slingo Originals is the wider catalogue of themed titles developed by Gaming Realms, the same studio behind Slingo Classic. If you want to explore beyond the original format, this is where to look. It brings together branded and themed variants in one place, each with its own mechanics, RTP and prize structure. RTPs vary by title, so check the paytable of whichever game you choose.

William Hill Slingo

William Hill Slingo is the branded title built specifically for William Hill Vegas. It follows the standard Slingo format, with a maximum win of £250,000. As with all titles here, verify the current RTP in the game’s own information screen before playing.

Slingo Advance

Slingo Advance takes the format in a different direction. Rather than starting with the full 5×5 grid available, you begin with only the first row unlocked and a single spin. As you match numbers, you unlock additional rows and earn more spins, so the game expands as you progress. It has a retro, space-themed design, and a Full House pays 10,000x your stake. Check the paytable for the current specs.

How to Play Slingo – FAQ

Is Slingo a slot or a bingo game?

It’s both. Slingo uses bingo-style number marking on a 5×5 card, but the numbers come from spinning reels, which gives it a slots structure. Most regulators and platforms classify it alongside slots.

How many lines can you make in Slingo?

There are 12 possible lines: 5 horizontal, 5 vertical and 2 diagonal. Clearing all 25 squares gives you a Full House.

What is the difference between a Joker and a Super Joker?

A Joker can only mark off a number in its own reel column. A Super Joker can mark off any number anywhere on the grid, making it the more flexible of the two.

Should I buy extra spins?

That’s a personal decision based on where you are in the game and your own limits. Extra spins are an optional feature. They don’t improve your odds in any reliable way.

What is RTP in Slingo and where do I find it?

RTP stands for return to player, the long-term theoretical percentage a game is designed to pay back over time. William Hill Vegas describes each Slingo title’s volatility and maximum win in the game information screen, rather than publishing a specific RTP figure.

Can you play Slingo on mobile at William Hill Vegas?

Yes. Slingo titles at William Hill Vegas are available on mobile. Check the individual game page to confirm compatibility with your device before you play.
