In the early 1990s, a programmer named Sal Falciglia had an idea. What if you combined the thrill of a slot machine with the familiar structure of bingo? The result was Slingo – a hybrid game that has since become a cult favourite among online gamblers.
Slingo is not a slot. It is not bingo. It is something in between. Players spin a reel at the bottom of a 5×5 bingo card, and numbers appear above. Match numbers to complete lines, earn points, and trigger bonuses. The game is simple to learn but surprisingly addictive.
This guide explains how Slingo works, the different symbols you will encounter, and where Australian players can find Slingo games online.
What Is Slingo?
Slingo is a game that blends the mechanics of slots and bingo. The name itself is a portmanteau of “slot” and “bingo”. The game was invented in 1994 by Sal Falciglia, who later founded Slingo Originals. The original game was released on AOL and became an unexpected hit.
Today, Slingo games are produced by several developers, including Gaming Realms, which holds the master license for Slingo. The game has evolved into dozens of themed variants, including Slingo Rainbow Riches, Slingo Deal or No Deal, and Slingo Starburst.
Why Slingo is different from slots and bingo:
- Unlike slots, you have a 5×5 card and can see your progress toward completing lines
- Unlike bingo, you spin a reel rather than waiting for randomly called numbers
- Unlike both, Slingo games typically include multiple bonus features and special symbols
- The game typically lasts 20 spins (one “game”) rather than infinite spins
Most Slingo games have an RTP (Return to Player) of 94% to 96%, which is comparable to many online slots. The volatility varies by game, but most Slingo games are considered low to medium volatility, meaning wins are relatively frequent but not massive.
Slingo vs Slots vs Bingo
| Feature | Slingo | Slots | Bingo |
|---|---|---|---|
| Game board | 5×5 number grid | Reels (3-6) | Ticket with numbers |
| Numbers called | Spun on a reel | Random per spin | Randomly drawn |
| Player control | Can choose to spin or use special symbols | Limited (spin only) | None (wait for numbers) |
| Game length | Fixed spins (usually 20) | Unlimited | Until game ends |
| Bonus features | Jokers, Super Jokers, Free Spins, Devils | Free spins, pick-me, multipliers | Limited |
How to Play Slingo – The Basics
The core of any Slingo game is a 5×5 grid. At the bottom of the screen is a slot reel with 5 columns, each containing numbers. Each spin of the reel reveals 5 numbers, one above each column. If a revealed number appears on your grid, it is marked off.
The objective of Slingo: Complete as many lines as possible. A line can be horizontal (any of the 5 rows), vertical (any of the 5 columns), or diagonal (top-left to bottom-right and top-right to bottom-left). Each line completed earns points and contributes to the final score.
How a typical Slingo game progresses:
- Each game consists of a fixed number of spins, usually 20
- After each spin, numbers are marked on the grid
- Special symbols may appear on the reels (see next section)
- Between spins, players may have the option to purchase extra spins or use power-ups
- After all spins are used, the game ends and players receive payouts based on lines completed
Most Slingo games allow players to bet between $0.20 and $100 per game. The payout depends on how many lines are completed. A “Full House” (all 25 squares marked) typically pays the maximum prize, often 250x to 1,000x the bet.
Example of a simple Slingo game:
A player bets $1 on a Slingo game. The reel spins and reveals the numbers 3, 17, 25, 32, and 48. The player’s grid contains 3, 17, and 25, so those squares are marked. The player now has two partial lines. Over the remaining spins, the player hopes to complete full lines. At the end of 20 spins, the player has completed 4 lines, earning a payout of $8 (for example).
Special Symbols and Bonus Features
What makes Slingo more interesting than pure bingo is the special symbols that appear on the reels. These symbols add strategy and excitement to the game.
Joker: The Joker symbol allows the player to mark any number in the column directly above where the Joker landed. This is one of the most useful symbols because it gives the player a choice.
Super Joker: The Super Joker allows the player to mark any number anywhere on the entire grid. This is rare but powerful, often used to complete a difficult line.
Free Spin (or Spin Again): This symbol grants an extra spin without reducing the remaining spin count. In effect, it extends the game.
Devil (or Skull): The Devil is the opposite of a Joker. If a Devil appears on the reel, the player loses a Joker (if they have any saved). Some Slingo games also allow the player to “buy off” the Devil for a small cost.
Bonus symbols: In themed Slingo games, additional symbols may appear that trigger mini-games or bonus rounds. For example, Slingo Rainbow Riches includes a “Road to Riches” bonus.
The importance of timing: Many Slingo games give players the option to use Jokers immediately or save them for later. Deciding when to use a Joker is the main strategic element. Using it early might help build momentum, but saving it could help complete a difficult line later when fewer spins remain.
Common Slingo Symbols
| Symbol | Effect | Rarity | Best Use |
|---|---|---|---|
| Joker | Mark any number in the same column | Common | Complete nearly-finished lines |
| Super Joker | Mark any number anywhere on the grid | Rare | Complete a line that would otherwise be impossible |
| Free Spin | Grants an extra spin | Common | Extend the game for more chances |
| Devil / Skull | Removes a saved Joker (or other penalty) | Common | Avoid if possible; can be “bought off” |
| Bonus Symbol | Triggers mini-game or bonus round | Rare | Provides additional payout potential |
Where to Play Slingo in Australia
Slingo games are not available at Australian-licensed online casinos because Australian-based online casinos are prohibited under the Interactive Gambling Act (IGA) 2001. However, many offshore online casinos offer Slingo games to Australian players.
Popular Slingo variants to look for:
- Slingo Rainbow Riches – themed after the popular slot
- Slingo Deal or No Deal – based on the TV game show

Important note for Australian players:
These platforms are not licensed in Australia. They are regulated in offshore jurisdictions such as Curacao. Players should understand that there are no Australian consumer protections for offshore gambling. Disputes must be pursued in the operator’s licensing jurisdiction.
Playing for free:
Many online casinos offer a demo mode for Slingo games. This allows players to learn the mechanics of Jokers, Super Jokers, and Devils without risking real money. Free play is recommended for first-time Slingo players, as the game’s rules are different from both slots and bingo.
Slingo is a unique genre that combines the best elements of slots and bingo. Invented in 1994 by Sal Falciglia, the game has grown into a cult favourite with dozens of themed variants produced by Gaming Realms and other developers.
Unlike pure slots, Slingo gives players strategic choices – when to use Jokers, whether to save them for later, and how to prioritise which lines to complete. Unlike pure bingo, players spin the reel themselves, creating a sense of agency. The special symbols add variety and excitement.
Australian players can find Slingo games at offshore online casinos. Popular variants include Slingo Rainbow Riches, Slingo Deal or No Deal, and Slingo Starburst. Free play (demo mode) is available on most platforms, allowing players to learn the mechanics before risking real money.
