Megaways Slots - The Complete Guide to Winning Ways

Megaways slots are online slot games that use a licensed mechanic created by Big Time Gaming (BTG) where each reel displays a random number of symbols on every spin. Instead of fixed paylines, Megaways games calculate ways to win by multiplying the symbol count across all reels, producing up to 117,649 ways to win per spin.

BTG patented the Megaways mechanic in 2016 with the release of Bonanza Megaways. Since then, the format has been licensed to major providers including NetEnt, Red Tiger, Blueprint Gaming, and Pragmatic Play. There are now over 200 Megaways slots available across licensed online casinos worldwide.

How Megaways Differs From Traditional Slots

• Paylines vs. ways to win: Traditional slots use a fixed number of paylines (typically 10 to 50) that never change. Megaways replaces this with a variable ways-to-win system that shifts on every spin.
• Dynamic reel height: Each reel randomly shows between 2 and 7 symbols per spin, meaning the grid layout changes constantly. Traditional slots use a static grid (e.g., 5x3).
• Adjacent reel matching: Wins form by landing matching symbols on adjacent reels from left to right, regardless of vertical position. There are no payline patterns to track.
• Cascading wins: Most Megaways games include cascading reels (also called tumbling reels), where winning symbols disappear and new ones fall in. This does not happen on most traditional slots.

For a broader comparison of slot formats, see our guide to types of slots. If you prefer wins based on symbol grouping rather than reels, Cluster Pays slots are another popular alternative.

Megaways slots use a random reel modifier that changes the number of symbols displayed on each reel before every spin. The total ways to win are calculated by multiplying the visible symbols across all six reels. When every reel shows the maximum of 7 symbols, the result is 7 x 7 x 7 x 7 x 7 x 7 = 117,649 ways.

1. Place your bet. Choose a stake within the game's range (most Megaways slots start at 0.20 per spin).
2. Spin the reels. The random reel modifier assigns each reel a height between 2 and 7 symbols.
3. Ways are calculated. The game multiplies the symbol count per reel to determine the total ways for that spin.
4. Wins are evaluated. Matching symbols on adjacent reels from left to right trigger payouts. No fixed paylines are needed.
5. Cascades trigger. Winning symbols are removed and new ones fall into place. Each cascade can create additional wins with increasing multipliers.

The Random Reel Modifier Explained

• Each of the six reels independently generates a height of 2 to 7 symbols per spin.
• The height is determined by a certified Random Number Generator (RNG) before symbols are placed.
• Higher symbol counts per reel mean more ways to win on that spin, but payouts depend on which symbols land.
• The average spin produces roughly 8,000 to 9,000 ways, not the 117,649 maximum. The maximum only occurs when all six reels display 7 symbols simultaneously.

Calculating Ways to Win (Up to 117,649+)

The formula is straightforward: multiply the symbol count on each reel together.

Some Megaways games exceed the standard 117,649 cap. White Rabbit Megaways expands reels to hold up to 12 symbols during free spins, reaching 248,832 ways. Rasputin Megaways pushes this even further to 2,985,984 ways. Each cascade in free spins also increases the win multiplier, which is why multiplier slots and Megaways pair so well together.

Cascading Reels & Tumbling Mechanic

After a winning combination lands, the winning symbols are removed from the grid. Remaining symbols drop down and new ones fill the empty positions from above. This cascade can chain into additional wins on a single spin without requiring a new bet.

In most Megaways games, each cascade during free spins increases a progressive multiplier that does not reset until the bonus round ends. This is the primary driver of large payouts. The mechanic is similar to Avalanche slots, which also use a symbol-removal system to create chain reactions.

Megaways slots are known for high volatility, unlimited win multipliers during free spins, and massive ways-to-win counts that change on every spin. These features combine to create a format with some of the highest max win potential in online slots.

Unlimited Win Multipliers in Free Spins

During the free spins bonus round, every cascade increases the win multiplier by one. Unlike traditional slots where multipliers are capped, most Megaways games allow the multiplier to climb without limit for the duration of the bonus. This is how max wins of 20,000x to 60,000x and higher become possible. For more on how free spins bonuses work, see our free spins slots guide.

Mystery Symbols & Symbol Transformations

Many Megaways games include mystery symbols that land as blank or question-mark icons and then transform into a single matching symbol. When multiple mystery symbols appear across several reels, they can create large winning combinations in a single reveal. Symbol transformation is also common in Scatter Pays slots, where wins form based on total symbol count rather than reel position.

Buy Bonus & Ante Bet Options

A significant number of Megaways games offer a buy bonus (also called Feature Drop or Feature Buy) that lets you skip directly to the free spins round for a fixed cost, typically between 50x and 100x your stake. Some games also include an ante bet option that increases your base bet by 20% to 25% in exchange for a higher chance of triggering the bonus naturally. Both options are banned under UKGC regulations. For a full list of games with this feature, see our bonus buy slots page.

Because Megaways slots carry high volatility, choosing where you play matters. Always verify that your casino is properly licensed and transparent about RTP settings. Casinos with documented complaints or predatory terms are listed on our blacklisted online casinos directory.

High Volatility vs. Low Volatility Megaways

The majority of Megaways slots are classified as high or extreme volatility. This means wins are infrequent but can be substantial when they land, particularly during free spins with progressive multipliers. A small number of titles, such as Fishin' Frenzy Megaways and Buffalo King Megaways, sit in the medium-to-high range and offer a slightly more balanced hit frequency.

If you prefer chasing large multiplier payouts, high-volatility Megaways with unlimited multipliers are the format to explore. Our best multiplier slots guide covers additional options beyond the Megaways mechanic.
