How Megaways Slots Work and Why the Number of Winning Ways Changes

Megaways slots use a changing reel layout instead of the fixed grid found in traditional slot games. On each spin, the reels can display different numbers of symbols, creating a new total of potential winning ways. In the familiar six-reel format, this figure can reach 117,649, although many spins produce considerably fewer. Developed by Big Time Gaming, the Megaways mechanic changes how winning combinations are formed and counted. Understanding the relationship between reel heights, matching symbols and additional game features makes it easier to interpret what happens during a spin. It also explains why a larger number of winning ways does not automatically mean a better chance of making a profit.

What Is the Megaways Mechanic and How Does It Work?

Megaways is a slot mechanic introduced by developer Big Time Gaming in 2016. Its defining feature is the variable number of symbols displayed on each reel. Conventional slots generally maintain the same arrangement throughout the game, such as five reels with three visible rows. A Megaways game can change its layout with every spin. One reel might display three symbols, another six and a third only two. These variations determine how many potential winning combinations are available when the reels stop.

The best-known Megaways arrangement contains six reels, each capable of displaying between two and seven symbols. Because the reel heights change independently, the total number of winning ways is not fixed. A spin displaying seven symbols on every reel offers 117,649 possible ways, while a layout with fewer symbols produces a smaller figure. Importantly, these are possible routes for forming combinations rather than guaranteed winning outcomes. Actual payouts still depend on the symbols that appear and the game’s paytable.

Although Big Time Gaming created Megaways, other developers have used the mechanic through licensing arrangements. As a result, Megaways games can differ considerably in appearance, bonus features, maximum payouts and mathematical behaviour. Some include additional symbol positions, expanding reels or alternative winning structures. The familiar six-reel arrangement is therefore a useful starting point, but it does not describe every Megaways release available in 2026. The rules displayed inside the individual game remain the most reliable guide to its particular features.

How Megaways Slots Differ from Traditional Payline Slots

In a traditional slot with fixed paylines, winning symbols usually need to occupy specific positions along predetermined lines. For example, a five-reel game might offer 20 paylines, each following a particular route across the reels. Even when matching symbols appear on consecutive reels, they may not form a paying combination unless their positions correspond to an active line. Megaways removes this restriction in its standard ways-to-win format. Matching symbols can form a combination across consecutive reels regardless of their vertical positions.

Consider a six-reel Megaways game in which three matching symbols appear on the first three reels. One might be near the bottom of the first reel, another at the top of the second and the third in the middle of the next reel. Their different positions do not prevent a payout if the game’s rules recognise that symbol combination. Most standard Megaways games evaluate matches from left to right, beginning with the first reel. The paytable specifies how many consecutive reels must contain the matching symbol before a prize is awarded.

Another difference is how multiple matching symbols contribute to a win. If the first reel contains one crown, the second contains two and the third contains three, those crowns can create six different three-reel combinations. The number comes from multiplying the matching symbols on the participating reels: 1 × 2 × 3 = 6. Each qualifying way is evaluated according to the applicable rules and payout. However, the game may award only the longest qualifying combination for a particular symbol, rather than paying shorter versions of the same match separately.

Why Does the Number of Winning Ways Change on Every Spin?

The number of Megaways changes because the game selects how many symbol positions appear on each reel. In the classic six-reel arrangement, every reel can contain between two and seven visible symbols. Once the reel heights have been determined, the game multiplies their values to calculate the total possible ways. For example, a layout showing three, five, two, seven, four and six symbols produces 5,040 ways: 3 × 5 × 2 × 7 × 4 × 6. The calculation reflects the available symbol positions, not the number of actual winning combinations.

The range can be substantial. When all six reels display two symbols, the calculation produces just 64 possible ways. At the opposite extreme, six reels containing seven symbols each provide 117,649 ways. Between these extremes are numerous combinations of reel heights, explaining why the counter can change dramatically from one spin to another. Some games also display an additional horizontal reel above the main reels. Its symbols may contribute to the visible positions below, depending on the design, but players should follow the game’s own counting rules.

A higher Megaways count means more potential symbol routes are available, but it does not guarantee a payout. A spin with 117,649 ways can still lose if the symbols fail to form qualifying matches. Conversely, a smaller layout can produce several wins when suitable symbols appear together. The game determines the outcome using its programmed rules and random number generator. The displayed Megaways figure helps explain the layout; it is not a probability percentage and should not be interpreted as a prediction of the next result.

How to Calculate Winning Ways and Understand Reel Cascades

Calculating the available ways is straightforward once the reel heights are known. Imagine a spin with four symbols on the first reel, three on the second, five on the third, two on the fourth, six on the fifth and four on the sixth. Multiplying 4 × 3 × 5 × 2 × 6 × 4 gives 2,880 possible ways. This figure counts every possible selection of one symbol position from each reel. It does not mean the game contains 2,880 winning combinations, because most of those routes may contain different symbols and therefore produce no prize.

To calculate an actual winning combination, only the matching symbols on the relevant consecutive reels are counted. Suppose a particular symbol appears twice on the first reel, three times on the second and once on the third, with no matching symbol on the fourth. If the paytable awards three-reel matches, this arrangement creates six winning ways for that symbol: 2 × 3 × 1 = 6. The game then applies the corresponding payout value and stake. Wild symbols may contribute to the combination, although their substitution rules vary between games.

Many Megaways slots also feature cascading reels, sometimes called reactions or avalanches. After a qualifying win, the winning symbols disappear and replacement symbols enter the vacant positions. The new arrangement is evaluated again, potentially creating another payout without requiring a separate paid spin. Cascades continue until no further qualifying wins appear. Certain games maintain a fixed reel height throughout these reactions, while others use additional features that can alter the available ways. Cascades can produce several consecutive payouts, but they do not guarantee that a winning sequence will continue.

What Do Changing Megaways Mean for Payouts, RTP and Volatility?

The number of winning ways influences how symbols can combine, but it should not be confused with Return to Player (RTP). RTP represents the theoretical proportion of total stakes that a game is designed to return across a very large number of plays. For example, a slot with a theoretical RTP of 96% is designed around an average return of £96 for every £100 wagered over its long-run mathematical model. This does not mean an individual player will recover £96 from a £100 session. Actual short-term results can differ considerably from the theoretical average.

More winning ways do not automatically produce a higher RTP. A game offering 117,649 ways can have a lower theoretical return than another slot with substantially fewer combinations. Developers balance symbol probabilities, paytable values and bonus features to establish the overall mathematics. Some titles also offer different RTP configurations, meaning the same game may operate with different published percentages depending on the version offered. Players should therefore check the RTP information in the game’s help section instead of assuming that the Megaways count determines its expected return.

Volatility is another important consideration because it describes how winnings are distributed. A highly volatile slot may produce extended periods with limited returns, interrupted by less frequent but potentially substantial payouts. A lower-volatility game generally distributes returns more evenly, although losing sequences remain possible. Megaways mechanics are often associated with games featuring considerable volatility, particularly when large bonus multipliers are involved. However, volatility differs between individual releases and cannot be established solely from the number of reels or winning ways.

How Bonus Features Affect Megaways Gameplay and Winning Potential

Free spins are common in Megaways games, but their rules vary. Some titles introduce multipliers that increase after consecutive cascades, while others expand reel heights or maintain a minimum number of winning ways throughout the bonus. For example, Big Time Gaming’s Max Megaways includes free-spin features alongside modifiers such as Maximum Megaways and Wild Bombs. Its six-reel game can display 117,649 ways, with particular features affecting the symbols or reel arrangement. These additions change how individual rounds develop, but triggering a bonus does not guarantee a profitable outcome.

Wild symbols provide another way to complete matching combinations by substituting for eligible regular symbols. Depending on the game, they may appear on specific reels, carry multipliers or form part of a separate bonus feature. Scatter symbols usually serve a different purpose, such as activating free spins, and often do not need to occupy consecutive reels. Some Megaways titles also include a Bonus Buy option that allows players to pay a specified amount to access a feature directly. Such purchases can be expensive relative to the normal stake and may be unavailable under local gambling regulations.

When comparing Megaways games, the most useful information is found in the paytable and game rules: the reel arrangement, maximum winning ways, RTP, volatility, symbol values, bonus conditions and maximum payout. It is also worth checking whether the displayed stake covers every available way and how multipliers operate during cascades. The advertised 117,649 ways describes the scope of possible combinations, not the likelihood of winning money. Understanding these distinctions helps players assess the mechanics without mistaking a large number of winning ways for a financial advantage. Since every paid spin carries a risk of loss, setting a spending limit remains more meaningful than trying to predict the next reel layout.
