Traditional online slots normally use a fixed grid and a set number of paylines. Megaways games take a different approach by changing the number of symbols displayed on each reel whenever a new spin begins.

As a result, the number of possible winning combinations can rise or fall from one round to the next. This guide provides Megaways slots explained in simple language.

It covers dynamic reels, ways to win, cascading symbols, extra horizontal reels, free spins, multipliers, return to player, and volatility. The Megaways mechanic was developed by Big Time Gaming and became widely known through Bonanza, released in 2016.

A common six-reel Megaways setup can display between two and seven symbols per reel, potentially producing as many as 117,649 ways to win. However, individual titles may use different layouts, features, and mathematical models.

Understanding these elements does not predict future results or guarantee winnings. It simply helps players read the game rules and compare different slot designs more accurately.

What Are Megaways Slots?

Megaways is a dynamic reel system rather than a single slot game. Big Time Gaming created the mechanic and later licensed it to other game studios, allowing developers to combine changing reel heights with their own themes and bonus features.

In many Megaways titles, each of the six main reels displays between two and seven symbols. The height is determined again for every new paid spin, so the game grid may look different from one round to another.

The word “Megaways” does not describe a jackpot size or guaranteed number of wins. It refers primarily to the changing reel structure and the resulting number of possible symbol combinations.

How Dynamic Reels Work

A traditional slot might use five reels with three fixed rows. A typical Megaways game instead uses six reels whose symbol counts can change independently.

One spin might show three symbols on the first reel, five on the second, four on the third, and different heights across the remaining reels. The next spin can produce an entirely new configuration.

Evolution describes the core Megaways mechanic as a system in which reel heights change on each spin, commonly displaying between two and seven symbols per reel. This dynamic format can generate thousands of possible winning routes.

Some titles also include a horizontal extra reel above the main grid. Symbols from this reel can add positions to the reels below, helping them reach their maximum height.

Megaways Versus Fixed Paylines

Megaways games usually use “ways to win” rather than traditional fixed paylines. A standard payline requires symbols to land on a predetermined path across the reels.

A ways system normally pays when enough matching symbols appear on consecutive reels, beginning with the leftmost reel. Their vertical position may not matter, provided they appear on the required adjacent reels.

This means the term “117,649 paylines” is often used informally but is not completely accurate. They are better described as 117,649 possible ways to win, because there are no fixed line patterns that remain identical on every spin.

Players should still read the specific paytable. Some symbols need three matching reels, while higher-value icons may pay with only two. Scatter symbols may follow entirely different rules.

How 117,649 Ways Are Calculated

The number of ways available on a spin is generally found by multiplying the number of active symbol positions on each reel.

When all six reels display seven symbols, the calculation is:

7 × 7 × 7 × 7 × 7 × 7 = 117,649

A smaller arrangement might display three, four, five, six, four, and three symbols. That spin would provide:

3 × 4 × 5 × 6 × 4 × 3 = 4,320 ways

The number shown on the screen therefore changes with the reel configuration. A higher ways count creates more possible symbol paths, but it does not guarantee that a paying combination will appear.

Cascading Reels and Reactions

Cascading wins are common in Megaways slots, although they are not required in every title. After a winning combination is formed, the symbols involved may disappear and new icons drop into the empty positions.

This creates another opportunity to form a combination without placing a separate paid spin. The sequence usually continues until no additional win is created.

Bonanza helped popularize the combination of Megaways and cascading reactions. Big Time Gaming describes its Dual Reaction system as allowing symbols to cascade in both directions.

Other titles may use falling blocks, avalanches, respins, or hold-and-win features instead.

Free Spins, Wilds, and Multipliers

Megaways slots frequently add free-spin rounds, expanding wilds, scatter symbols, increasing multipliers, or feature-triggering collections. However, these extras vary considerably between games.

In several titles, each successful cascade during free spins raises a win multiplier. Gonzo’s Quest Megaways, for example, combines the Megaways structure with cascading Avalanche wins and multipliers that increase during continued reactions.

Other games provide a gamble before the bonus round. Extra Chilli Megaways includes a wheel that can increase the awarded free spins, but attempting to improve the prize may also involve additional risk.

Always check whether wilds substitute for every symbol, whether scatters pay anywhere, and whether multipliers reset after each spin.

RTP and Volatility Still Matter

A large number of win ways does not automatically create a higher return to player. RTP is determined by the complete mathematical design, including symbol frequency, paytable values, bonus probabilities, and feature prizes.

Theoretical RTP represents the percentage of turnover a game is designed to return over extensive play. Actual results during a short session can be much higher or lower because RTP becomes meaningful only across a very large sample.

Volatility describes how wins are distributed. Highly volatile games commonly produce less predictable results with the possibility of larger but rarer prizes, while lower-volatility products generally provide smaller and more frequent returns.

Megaways slots replace a fixed reel layout with dynamic symbol heights and a changing number of possible win ways. A typical six-reel format can reach 117,649 combinations when every reel displays seven active positions.

Many games combine this system with cascading wins, free spins, wild symbols, and increasing multipliers. Nevertheless, these features differ between titles, and more ways do not guarantee better odds, a higher RTP, or a profitable session.

Before playing, open the paytable and review the reel structure, winning-symbol rules, RTP, volatility, feature conditions, and maximum payout. Use licensed platforms, set firm spending and time limits, and treat every spin as entertainment with an uncertain result.
