At some point between loading a classic 5-reel and stumbling onto a Megaways title, a lot of Australian pokies players land on something labelled 243 ways and move on without thinking about it. The number is specific: a direct product of the grid dimensions. It changes how wins form, how often they hit, and why the base game on these titles feels different. For anyone playing Aus pokies online who’s curious what it represents, the explanation is simpler than it looks.
Where 243 Comes From
The number is a product of the grid. Specifically, the grid dimensions.
A standard 243 ways title runs on a 5×3 layout: five reels, three symbol positions on each reel. In this format, wins pay when matching symbols land on consecutive reels from left to right, on any position. Any position qualifies. Any symbol on reel one can connect to any symbol on reel two, which connects to any on reel three, and so on.
The maths: 3 positions per reel, across five reels. 3? = 243. Every spin, all 243 combinations are active. Every combination runs on every spin.
Why It Was a Step Forward
Before ways-to-win existed, players had to select and pay for individual paylines. A 25-line game at minimum coin per line was one thing; the same game at max lines cost significantly more per spin. Only active lines paid, so players who trimmed their line count left combinations on the table.
243 ways removed that friction entirely. One bet covers every possible combination on the grid. Microgaming introduced the format in 2010 with Thunderstruck II (RTP 96.65%), and Australian pokies online catalogues have carried it ever since. The format spread quickly because it solved a real problem and kept the mechanic clean.
How Ways-to-Win Differs from Paylines
Payline titles require matching symbols to land on a specific predetermined path. Wins only register on the exact path the active line follows across the reels.
With 243 ways, position within a reel is irrelevant. Three matching symbols on reels one, two, and three pay regardless of which row each one occupies. That’s nine possible arrangements for a three-symbol win on just the first three reels, compared to however many active lines a payline game has running through those same positions.
The table below puts both formats side by side:
| Feature | Payline Format | 243 Ways Format |
| Win condition | Symbols on active line | Symbols on consecutive reels, any row |
| Lines to activate | Yes, can be selective | All 243 active every spin |
| Win frequency | Depends on active lines | Higher on average |
| Bet structure | Per line or per spin | Per spin, fixed |
| Grid | Usually 5×3 | Always 5×3 |
| Examples | Book of Dead, Starburst | Thunderstruck II, Immortal Romance |
What 243 Ways Means for Return and Variance
More combinations active per spin means wins form more often in the base game, something Australian pokies players moving across from payline titles tend to notice immediately. At the same volatility setting, a 243 ways title tends to produce more frequent, smaller hits than a comparable payline title.
RTP is set independently by the developer and varies across titles. What shifts is the session shape: returns come more regularly through the base game, keeping the bankroll moving between bonus triggers.
The Volatility Question
Most 243 ways titles run medium volatility, though high and low variance versions exist across the catalogue. The format works well for games where the developer wants steady base game returns alongside a bonus feature that provides the bigger swings.
Immortal Romance (Microgaming, RTP 96.86%) is the most-played 243 ways title across online slots Australia and best online pokies Australia real money catalogues. Base game hits regularly; four free spins features escalate in value as players progress through the story. Thunderstruck II follows similar logic. Both have been in continuous circulation on online casino Australia real money platforms for over a decade.
Popular 243 Ways Titles Worth Knowing
Microgaming built the core catalogue, and these are the titles that show up most consistently across best online pokies Australia real money platforms:
- Immortal Romance (Microgaming, RTP 96.86%): four-stage free spins feature, one of the longest-running titles in the format;
- Thunderstruck II (Microgaming, RTP 96.65%): the title that established 243 ways as a mainstream format in 2010;
- Tomb Raider (Microgaming, RTP 97.03%): higher RTP end of the format, standard free spins structure;
- Game of Thrones (Microgaming, RTP 96.03%): four jackpot tiers alongside the ways mechanic;
- Jurassic World (Microgaming, RTP 95.45%): three distinct free spins modes tied to film characters.
Other developers have since adopted the format, but Microgaming’s originals remain the most widely available across the catalogue.
243 Ways vs Other Multi-Way Formats
The 243 format cracked open a question that developers were happy to keep asking: what if the grid was bigger?
A 5×4 layout (five reels, four rows) produces 4? = 1,024 ways. A 5×5 grid gives 3,125 ways. Some titles use irregular reel heights to hit specific numbers (720 ways, 1,024 ways, 3,125 ways), each produced by the same multiplication logic applied to a different grid configuration.
Megaways takes this further by making the reel height variable on every spin, which is why its ways-to-win count fluctuates rather than holding a fixed number. It’s the most volatile end of the spectrum across Australian pokies online. The 243 ways format is the fixed-grid version of the same underlying idea: remove paylines, count positions, and multiply across reels.
For best online pokies players deciding between formats, the fixed 243 number has one advantage over variable Megaways: the win frequency is consistent and predictable. The grid holds its shape on every spin, so the coverage stays fixed.
Putting It Into Practice
Most platforms carrying Australian pokies stock 243 ways titles, though how deep the catalogue runs varies considerably. Lucky Green Casino carries Immortal Romance and Thunderstruck II alongside its broader selection, with both available in demo before any real money is in play, useful for getting a feel for the base game rhythm before committing to a bet size.
For players moving across from payline titles, running a few demo spins on a 243 ways game makes the difference tangible. The base game hits differently. That’s easier to judge from inside a session than from a description.
FAQ
Do all 243 ways activate automatically?
Yes. Every combination runs on every spin as part of the base bet, at a fixed cost per spin.
Does 243 ways mean more frequent wins?
Generally yes, compared to a payline title with fewer active lines. More combinations covered per spin means matching symbols have more ways to connect. The size of individual wins in the base game tends to be smaller on average, with larger returns concentrated in the bonus feature.
Are 243 ways titles available on mobile?
All major 243 ways titles on online casino Australia real money and online slots Australia platforms are fully optimised for mobile. The fixed 5×3 grid reads clearly on smaller screens, with the fixed grid making everything easy to follow.
Can the ways-to-win number be higher than 243?
Yes. Larger grids produce higher fixed way counts: 1,024 ways on a 5×4 grid, 3,125 on a 5×5. Megaways titles go further still with variable reel heights, reaching up to 117,649 ways on a maximum configuration. The 243 number is specific to the 5×3 fixed grid.
Which 243 ways title has the best RTP?
Among widely available titles on best online pokies Australia real money platforms, Tomb Raider (Microgaming) sits at 97.03%, which is high for any format. Immortal Romance at 96.86% and Thunderstruck II at 96.65% are also above the general average for online pokies.
