Traditional slot games usually keep the same reel layout from one spin to the next.

Megaways slots change that idea by allowing the number of symbols appearing on individual reels to vary, which can dramatically change how many winning combinations are possible.

If you are wondering What Is a Megaways Slot, the simplest answer is that it is a slot using the Megaways mechanic originally developed by Big Time Gaming.

The system replaces many fixed-payline structures with dynamic reels and changing ways to win, making each spin look and behave a little differently.

What Makes a Slot a Megaways Game?

Megaways is a proprietary slot mechanic created by Big Time Gaming. Rather than keeping the same number of visible symbols on every reel, the system can change reel height from one spin to another.

Evolution, which owns Big Time Gaming, explains that classic Megaways mechanics can display between two and seven symbols on each reel. With six reels showing seven symbols each, the game can reach 117,649 possible ways to win.

That number comes from multiplying the reel possibilities:

7 × 7 × 7 × 7 × 7 × 7 = 117,649.

The exact configuration can vary between individual games, so not every Megaways title uses exactly the same layout.

How Dynamic Reels Change Every Spin

Imagine a six-reel slot.

On one spin, the reels might display 3, 4, 5, 3, 6, and 4 symbols. On the next spin, those reel heights could change again.

As the number of visible symbols changes, the number of possible winning ways changes too.

This is the main difference between Megaways and a conventional fixed-reel slot. Instead of knowing that every spin has exactly 20 paylines or 243 ways to win, the available combinations can expand or contract with each result.

That changing structure creates much of the mechanic’s visual variety.

How Ways to Win Are Calculated

Megaways games generally use a ways-to-win system rather than traditional fixed paylines.

A common structure requires matching symbols to appear on consecutive reels starting from the left. Their exact vertical position may not matter.

Suppose reels one through three contain two, three, and four matching symbols.

That could produce:

2 × 3 × 4 = 24 combinations.

More matching symbols across more reels can create many additional combinations.

Big Time Gaming’s Monopoly Megaways, for example, uses up to 117,649 ways to win.

The system can initially look complicated, but the game software performs the calculations automatically.

Why Tumble Features Often Appear in Megaways Slots

Megaways and tumbling reels are seperate mechanics, but developers frequently combine them.

With a tumble feature, symbols involved in a winning combination disappear. Replacement symbols then fall into the empty spaces.

If the new arrangement creates another qualifying combination, another tumble can occur.

Pragmatic Play’s Money Stacks Megaways combines up to 117,649 ways to win with tumbling reels, showing how naturally the two systems work together.

Tumbles add another layer of movement because one paid spin can potentially produce several consecutive symbol arrangements.

However, not every Megaways game must use identical tumble rules.

Multipliers Can Make Tumbles More Complex

Many Megaways titles connect consecutive wins with multipliers.

A multiplier might start at 1x and increase after each successful tumble. If another combination appears before the sequence ends, the new win may receive the larger multiplier.

Money Stacks Megaways, for example, increases its total win multiplier with tumbling wins during one of its bonus features.

Other games handle multipliers differently. Some add multiplier symbols together, while others only activate enhanced multipliers during free spins.

This is why the paytable matters. Two games carrying the Megaways name can still have very diffrent bonus systems.

Why 117,649 Is Common but Not a Universal Limit

The number 117,649 is strongly associated with Megaways because it represents six reels with up to seven positions on each reel.

But developers have expanded the concept.

Pragmatic Play’s Great Rhino Megaways, for example, advertises more than 200,000 ways to win, while Big Time Gaming’s Gold Megaways can reach up to one million ways during its feature.

So Megaways should not simply be defined as “a 117,649-ways slot.”

The more important idea is the dynamic reel system that changes the number of available combinations.

How Free Spins Work in Megaways Games

Free-spin rounds often take the core reel system and add another mechanic.

A bonus might introduce increasing multipliers, extra wilds, guaranteed minimum reel heights, or additional free spins.

Big Time Gaming’s Max Megaways includes several possible free-spin modifiers, while its main six-reel layout provides up to 117,649 ways.

Pragmatic Play titles also frequently combine Megaways with tumbling wins and growing multipliers during bonus rounds.

The exact rules vary significantly, so understanding one Megaways game does not mean you automatically understand another.

Always check how the bonus is triggered and what actually changes once it begins.

Does More Megaways Mean Better Odds?

Not necessarily.

Seeing 117,649 or even one million possible combinations sounds impressive, but the number of ways alone does not tell you whether a game has a better theoretical return.

Payout values, symbol frequncy, reel probabilities, bonus mechanics, and game mathematics all contribute to the final RTP.

The UK Gambling Commission explains that RTP is a long-term theoretical average measured across a significant amount of play, not the amount an individual should expect during one session.

A slot with thousands of possible winning ways can still be highly volatile.

Megaways Games Can Have Different Volatility

Megaways does not automatically mean one specific volatility level.

For example, Evolution lists Monopoly Megaways as high volatility with a 96.50% RTP, while Max Megaways is also categorized as high volatility and lists a 96.37% RTP.

Another Megaways title can use different values.

Volatility broadly relates to how payouts may be distributed, while Megaways describes the dynamic reel mechanic.

They are related parts of the overall game design, but they should not be treated as the same concept.

Why Beginners Should Read the Paytable

The Megaways label tells you how part of the slot works, but it does not explain everything.

Before playing, check how many matching symbols are required, whether wins must start from the left, what tumble rules apply, and whether multipliers reset between spins.

You should also check RTP information, betting range, bonus conditions, volatility where provided, and maximum payout rules.

Do not assume that two Megaways titles from different studios behave mechanicly the same way simply because they share the licensed system.

Understanding What Is a Megaways Slot starts with dynamic reels and changing ways to win. Reel heights can vary from spin to spin, while tumbling symbols, multipliers, and free-spin features often add extra layers.

Before trying any Megaways game, open its paytable and check the exact reel structure, payout rules, RTP, and bonus mechanics rather than judging it by the headline number of ways.
