Megaways slots explained: the product, not the promise

The number attached to megaways slots in every headline — 117,649 — is not a measurement. It is 7 to the power of 6, the product of six reels each showing at most seven symbols, and you can compute it on paper without opening a game. That is the useful thing about this mechanic: almost everything quoted about it is arithmetic, so almost everything can be checked. This page does the arithmetic, shows why the headline is a maximum rather than a typical value, explains why a larger count does not imply a larger return, and states exactly what our own files hold about the studios involved: presence on lobby lists, and nothing else.

What the name describes

In a conventional design the grid is fixed: a set number of reels, each showing a set number of symbols, with wins checked along declared lines. The mechanic behind megaways slots changes one thing — the number of symbols a reel shows is decided per spin, within a range — and then counts wins as combinations across adjacent reels rather than along declared lines.

Two consequences follow immediately. The number of counted combinations is no longer a property of the game; it is a property of the spin. And the figure printed on the marketing material is the largest that product can reach, which happens only when every reel simultaneously lands at its maximum height.

The counting rule itself is the ways rule: take one symbol position from each reel, in order, and every such selection is a combination that gets checked. With three positions on each of five reels the count is 3 × 3 × 3 × 3 × 3 = 243. With four on each of five it is 4⁵ = 1,024. These are products of a substituted grid shape. They are not readings of any game, and our files record no grid, for any game, from any studio.

The name itself is a brand, applied to designs built on this variable-height rule. Our library holds no licensing records, no studio agreements and no game titles, so this page will not tell you which studio owns the name or which games carry it. What it can tell you is the arithmetic, which belongs to nobody. For contrast, see the counting rule that abandons combinations altogether.

The product, substituted step by step

Take six reels, each able to show between two and seven symbols. Every figure below is a substitution chosen to expose the algebra.

The column on the right is the whole of the famous number’s provenance. Note how violently it moves: going from five symbols per reel to seven multiplies the count by roughly seven and a half, while the grid itself grows by only two rows. That is what a sixth power does, and it is why the headline is so large and so misleading at the same time.

A mixed spin makes the point better than a uniform one. Substituting heights of 3, 7, 2, 5, 4 and 6 on the six reels: 3 × 7 × 2 × 5 × 4 × 6 = 5,040. That spin is counting 5,040 combinations, about one twenty-third of the headline, and nothing about it is unusual. Most spins in any design of this shape land somewhere in the low thousands.

Maximum against average: the factor of fourteen

Suppose, purely as a substitution, that each reel’s height is equally likely to be any of two, three, four, five, six or seven, and that the reels are independent. The average height is (2+3+4+5+6+7) ÷ 6 = 4.5. Because the reels are independent, the average product is the product of the averages: 4.5⁶ ≈ 8,304.

So on this substitution the typical spin counts about 8,300 combinations against a headline of 117,649 — a factor of roughly fourteen. Turn it the other way and the point is sharper: for the headline count to occur, all six reels must simultaneously land at the maximum. On the same substitution that is (1/6)⁶ = 1 in 46,656 spins.

That single figure is the most useful thing on this page for anyone reading marketing copy about megaways slots. The number in the headline describes a spin that, on a plausible substitution, happens once in tens of thousands. It is not a lie — the count really can reach that — but it is the ceiling of a distribution being presented as its description.

We are labelling the substitution rather than hiding it, because the real height distribution is a property of each game’s implementation and our files contain none. A design that weights tall reels more heavily would raise the average considerably; one that weights short reels would flatten it. Without the game’s own numbers, nobody outside the studio can say which.

Cascades, and why the count changes mid-stake

High-count designs are almost always paired with cascading: winning symbols are removed, new ones fall into the gaps, and the win check runs again. That pairing has an arithmetic consequence which is rarely spelled out, and it is the reason megaways slots feel different from a fixed-grid game with the same return.

When symbols are removed and replaced, the reel heights can be re-decided for the replacement. So a single stake does not count one combination total; it counts one, then another, then another, with the count changing at every step of the chain. Substituting a chain of three steps with per-step products of 5,040, then 1,200, then 360, the stake was evaluated against 6,600 combinations across the chain rather than against any one of those figures.

The effect on the numbers a player sees is straightforward. A single stake can produce several small resolutions in sequence, which reads on screen as a run of wins even when the total is below the stake. It can also, occasionally, produce a long chain, which is where the large outcomes in these designs come from. Neither behaviour requires the average return to be unusual; both change the variance substantially. The pay table is set against chained probabilities, so the designer decides the average and the chain decides the shape.

Our files contain no chain-length data and no step probabilities for any game, so the three-step substitution above is illustrative arithmetic and nothing else.

Why more ways is not more return

This is where arithmetic settles an argument that adjectives cannot. A game’s return is the sum, over all outcomes, of each outcome’s probability multiplied by its payout. Increasing the number of counted combinations increases the number of terms in that sum. It says nothing about the sum.

Work it with substitutions. Suppose a design counts 243 combinations and pays 5 units for a particular three-symbol hit, and a redesign counts 24,300 combinations — a hundred times more — while paying 0.05 units for the equivalent hit. If the probability of any single combination hitting falls by the same factor of a hundred, the two designs return identically. Multiply the count, divide the pay, and the product is untouched.

Designers are of course free to move the return as well, in either direction. The point is only that the ways count does not tell you which way they moved it, and a bigger count is not evidence of generosity. Our files contain no return-to-player figure for any game from any studio, so we cannot tell you where any real design sits, and we will not print a percentage we did not read from a document.

What the ways count does change reliably is the texture. More counted combinations tends to mean more frequent small resolutions and — when combined with cascading, which these designs usually are — longer chains from a single stake. That is a change in variance and in how a session feels, which is exactly the thing marketing is entitled to sell and statistics is not obliged to endorse. Put bluntly: megaways slots are a variance product, not a value product, and the arithmetic above is the whole of the argument. The return side is handled in why a bigger ways count leaves the return where it was.

What our files hold about the studios behind megaways slots

Thirty-three of our hundred operator records list the studios named on their own lobby. Big Time Gaming appears on 18 of the 33, or 55%. For context within the same census: Hacksaw is on 32, Pragmatic Play on 28, Nolimit City on 25, Relax on 21, Push Gaming on 18, Yggdrasil on 18, ReelPlay on 5, 4ThePlayer on 4, Print Studios on 7.

That is the extent of what we hold about the suppliers behind megaways slots. We do not hold which games any of those studios supplies to any of those lobbies. We do not hold which of them build on the variable-height rule, and we are not going to assign the mechanic to studios from memory and present the assignment as a reading. Several of the names above are widely associated with high-count designs; our documents do not say so, so this page does not.

The counting caveat applies here as everywhere in this library. Nolimit City appears across the lists as four different strings, Play’n GO as three including two differing only in the apostrophe character, the Microgaming family as four including two platform brand names. A raw string tally invents studios and undercounts the real ones. The 18 above is after merging, and there are no variants of Big Time Gaming’s string in our data, which is itself mildly notable — it is one of the few heavily distributed studio names that every lobby spells the same way.

Lobby lists were read in records checked on 26 August 2026. A lobby can change the week after, so the 18 is a count as of that reading and nothing more durable than that. The wider set is in the wider census these eighteen lobby lists come from.

What a big count does to the size of a win, and what happens next

High-count designs are sold on large occasional outcomes, so the clauses governing large outcomes matter more here than anywhere else in a lobby. Fourteen records in our library publish a payout cap, and those caps are the arithmetic that decides what a large win is actually worth.

Substitute a win of 100,000 units and read it against caps we did read. Against Oshi Casino’s €4,000 a day (clause 12) the balance takes 25 payout days. Against Instant Casino’s €4,000 a day (clause 8.1), the same 25. Against Wild Fortune’s €15,000 a month (clause 11.8) it is just under seven months. Against Bitdreams’ €20,000 a month (Section 11), five months. Against Mirax’s €10,000 a week (clause 8), ten weeks. Against CryptoLeo’s 50,000 USDT a month (clause 7.9), two months. Against Wild.io’s $100,000 a week (clause 9.6) or CoinCasino’s €500,000 a month (clause 9.6), one payout.

Vave’s terms add a second mechanism for the same problem: clause 8.1 sets a maximum processing period of three days, and clause 8.8 says a balance above 50,000 USDT is paid in equal instalments over up to thirty days. Terms read 25 August 2026, and the section is transcribed in the instalment clause read in full. So on the same substituted 100,000, one document produces a single payout, another produces twenty-five daily ones, and a third produces instalments across a month. The paperwork clock alongside them is counted in the document period that runs before a large balance moves.

None of that is a property of megaways slots or of any mechanic. It is a property of the terms page, and it is the reason a mechanic article that stops at the reels has skipped the part with the money in it.

Five checks for any high-count claim

First, ask whether the number is a maximum. If a page prints 117,649 without the words “up to”, it has presented a ceiling as a description, and on a plausible substitution the ceiling arrives once in 46,656 spins.

Second, ask what the average is. Any page confident enough to print a headline count should be able to state the height distribution behind it; almost none do, because that distribution is the game’s own property.

Third, refuse the inference from count to return. The two are independent by construction, and a page that treats a bigger count as better value has made an arithmetic error, not a judgement call.

Fourth, look for a game title beside every percentage. A return figure with no game name and no configuration describes nothing, and the same design can ship in several configurations. Our files hold no such figures at all, which is why none appears on this page.

Fifth, read the cap. On substituted numbers above, the same win is one payout at one operator and twenty-five at another, and that difference is written in a numbered clause that takes a minute to find. For anyone comparing megaways slots across sites, it is a far larger difference than anything happening on the reels.

Everything this page asserts, in full: 18 of 33 lobby lists name Big Time Gaming; no game titles, grids or return figures exist in our files; every product, average and payout-timing figure above is a labelled substitution; and the caps and clause numbers are readings, dated. They are the fields behind top no KYC casinos, ranked from clause numbers rather than reel counts.
