243 ways slots explained

What are 243 ways slots?

A 243 ways slot is a video slot that pays for matching symbols on consecutive reels, counted from the leftmost reel, without asking them to sit on a drawn line. A cherry on the top row of reel one, the bottom row of reel two and the middle row of reel three is a three-of-a-kind win, even though no straight or zig-zag line joins them. That is the whole idea, and it is why the format is also called “all ways”, “all-ways pays” or simply “ways to win”.

Among the types of slot machine we cover, the format sits inside the wider family of ways-to-win slot machines, alongside 1,024-ways grids and the variable-reel Megaways slot machines. It is the smallest and oldest standard size in that family, and it is still common because it fits the classic 5 × 3 window that most players already know from video slot machines with paylines.

Nothing about the format changes how the result is chosen. As on every online slot, a random number generator picks the stopping position of each reel strip before the animation starts. The 243 ways rule only decides which of the symbols that land are read as a win.

Where the number 243 comes from

Each reel shows three symbols, and a winning route can pass through any one of them. The number of distinct routes across five reels is therefore three choices, multiplied five times over.

The same arithmetic explains every other ways count. Add a fourth row and it becomes 4 to the power of 5, or 1,024; let every reel change height on each spin and you get the Megaways range. Our comparison of Megaways and 243 ways walks through those differences side by side, and the short answer to what 243 ways means is kept on its own page for quick reference.

How a 243 ways slot counts and pays a win

Most 243 ways slots apply the same four checks after the reels stop. The game’s help screen confirms the details for each title, including whether wins also pay from right to left.

1. Take each symbol that appears on reel one.
2. Check whether the same symbol, or a wild symbol that substitutes for it, appears anywhere on reel two. If not, that symbol has no win.
3. Keep moving right, reel by reel, until a reel has none of that symbol. The run length (3, 4 or 5 reels) sets which paytable line applies.
4. Multiply the number of matching symbols on each reel in the run. That product is the number of ways being paid, and each way receives the paytable amount.

A worked 243 ways example

Suppose a crown symbol lands twice on reel one, once on reel two and twice on reel three, with none on reel four. That is a three-reel run, paid 2 × 1 × 2 = 4 times. If the paytable lists three crowns at 0.25× the total stake, a 20p spin pays 5p per way, so 20p in total. Had a wild also landed on reel two, the middle factor becomes 2 and the win doubles to 8 ways, or 40p.

The illustrative figures show a quirk of the format: a win can equal or fall short of the stake. Since 31 October 2021, UK rules stop online slots from celebrating a return that is the same as or smaller than the stake, so the 20p and 15p results above would be shown quietly. Our page on losses disguised as wins explains the rule.

How the stake works on a 243 ways slot machine

There are no lines to switch on or off, so you choose only the total stake per spin. Some studios show it as a coin value multiplied by a fixed bet multiplier; others show a plain pound figure. Either way, the paytable values scale in direct proportion to the total stake, so doubling the stake doubles every prize.

Because a 243 ways game spreads its returns across so many routes, individual pays per way are small. That is how the maths stays balanced: a game that pays far more often has to pay less each time to land at the same RTP. The help screen lists the exact per-symbol values; reading it is the quickest way to judge whether the base game leans on frequent small returns or on its bonus round.

UK online stake limits apply to the total stake per spin, not per way: £5 for players aged 25 and over (from 9 April 2025) and £2 for players aged 18–24 (from 21 May 2025). The Gambling Commission’s online slots stake limit guidance (opens in a new tab) sets out how a game cycle is counted.

243 ways vs paylines: what really changes

A payline slot only pays symbols that sit on one of its drawn routes. The all-ways format effectively draws every possible left-to-right route at once. The practical differences are smaller than the headline number suggests.

Ways do not make a slot fairer or more generous. A 10-line game and a 243-ways game can carry the same RTP; the designer simply arranges the reel strips and paytable differently. Line counts and ways counts both matter less than they look.

RTP, volatility and cost of 243 ways slots

In the 243 ways titles in our facts sheet, published default RTPs run from about 96% to 96.86%, and several studios supply lower versions to operators that ask for them. Volatility is spread right across the scale, from medium games such as Narcos to an extreme rating on Nolimit City’s The Rave, which shows that the ways count does not fix the risk profile. Volatility depends far more on how much of the return is held back for the bonus round.

The cost of play follows the usual arithmetic. The table uses a 96% RTP, so the long-run average cost is 4% of the amount staked. Any single session can land far above or far below these figures.

At the UK minimum of 2.5 seconds per spin, 100 spins take at least 4 minutes 10 seconds, so the hourly turnover can be large even at modest stakes. Our slot cost calculator lets you change the stake, RTP and spins per hour.

243 ways slot examples on UK sites

These are 243 ways games with specifications in our verified data. Each figure is the developer’s or a reference listing’s default; always check the version your casino runs in the game’s help screen.

Thunderstruck II and Immortal Romance are the best-known all-ways games from the Microgaming catalogue now run by Games Global, and Immortal Romance II keeps the 243 ways layout. Twin Spin adds NetEnt’s linked twin reels, which can grow during a spin, and Narcos is a medium-volatility licensed title. IGT’s Fortune Coin also lists 243 ways; it shares its name with, but is a different thing from, the Fortune Coin Company behind the first video slot machine in 1976.

243 ways slots that expand beyond 243

Many newer games start at 243 ways and add rows or reels during features, so the count printed on the lobby tile is only the base figure. Examples from our checked data:

• Vikings plays at 243 ways in the base game and switches to a 7 × 5 grid with 78,125 ways in its Raid Spins.
• Phoenix Sun grows its reels from three to six rows, taking the count from 243 to 7,776.
• Dancing Drums also runs at 243 ways, rising to 7,776 in free spins.
• East Coast vs West Coast and Punk Rocker begin at 243 and use xWays-style symbols to reach 84,375 and 46,656 ways respectively.

Expanding counts usually come with higher volatility, because the extra ways are concentrated in features that land rarely. The base game still behaves like a normal 243 ways slot, which is where most of your spins are spent.

Max win on 243 ways slots at UK stake limits

Max win is quoted as a multiple of the total stake, so the pound figure depends on what you bet. Here is how four of the examples above convert at common UK stakes, including the £2 cap for players aged 18–24. Some casinos also apply a lower cap of their own; our page on max win caps explains how those work.

A max win is a ceiling written into the maths, not a likely outcome. It may come from a rare combination of features that most players never see, so treat it as the edge of the range rather than a target.

243 ways on casino machines and pub fruit machines

All-ways layouts are common on casino-floor video slots, and in Great Britain those machines sit in the gaming machine categories set by law. A Category B1 machine in a casino allows up to £5 a spin with a £10,000 top prize; Category B3 machines in betting shops, bingo halls and adult gaming centres allow £2 a spin and up to £500. The Gambling Commission’s gaming machine categories page (opens in a new tab) lists the full set, and our UK slot machine categories guide explains where each one is found.

A traditional pub fruit machine is a different animal. Category C machines cap the stake at £1 and the prize at £100, and their games revolve around a win line plus nudges, holds and a feature board rather than ways counting. Online slots are not part of these categories, which is why an online 243 ways game can carry a top prize thousands of times the stake.

Is a 243 ways slot worth it? Pros, cons and who it suits

The format suits players who like steady screen activity and simple rules, especially in medium-volatility titles. Players who prefer fewer, bigger hits may find the frequent small returns distracting. Either way, set a budget first; our bankroll guide helps with that.

243 ways slot myths and facts

• Myth: 243 ways means 243 separate bets. Fact: you place one total stake; the ways are routes for reading the result.
• Myth: more ways means better odds of profit. Fact: the RTP is set by the maths model, and the paytable shrinks as routes multiply.
• Myth: a near-full screen means a big win is close. Fact: each spin is independent, and near misses carry no information about the next one.
• Myth: some 243 ways games are “due”. Fact: online games cannot adjust results to hit a target return; the slot machine myths guide covers the rest.
