Megaways Slots Explained: How They Work and Why They’re Different
If you have browsed an online casino lobby recently, you have almost certainly seen the word Megaways on a game title. It appears everywhere — on slots with dragons, heist themes, ancient temples, and game show names — and for good reason. Megaways is one of the biggest innovations in online slots history, and once you understand what it does, the appeal becomes obvious immediately.
This guide explains exactly what Megaways slots are, how the mechanic works, what features you will typically find inside them, and how to decide whether they suit you.
What Are Megaways Slots?
Megaways is a patented slot mechanic created by Australian developer Big Time Gaming. Rather than using fixed paylines — where winning combinations only count if symbols land on specific pre-set lines — Megaways slots use a system where the number of symbols on each reel changes randomly with every spin. Because the reel height keeps shifting, the number of possible winning combinations changes with it, sometimes dramatically.
The result is a game that feels genuinely different from spin to spin, rather than one that repeats the same layout hundreds of times. That unpredictability is exactly what makes Megaways games so popular with players who find traditional slots repetitive.
How Is Megaways Different from a Standard Slot?
A standard video slot typically has five reels with three symbols visible on each one. That produces a fixed set of paylines — often 10, 20, or 25 — that never changes. You always know exactly how many ways to win exist before you spin.
Megaways works the opposite way. Each reel can display a different number of symbols on every single spin, usually somewhere between two and seven. Because the reel height keeps changing, the total ways to win is recalculated fresh on every spin. One spin might produce a few hundred ways to win. The next might produce over 100,000.
How the Megaways Mechanic Works
The ways-to-win count in a Megaways game is calculated by multiplying the number of visible symbols on each reel together. Most standard Megaways games use six reels. If all six reels show their maximum of seven symbols simultaneously, the calculation is 7 × 7 × 7 × 7 × 7 × 7, which equals 117,649 ways to win — a figure you will see quoted often in Megaways marketing.
In practice, reels rarely all hit their maximum at once. You might see two symbols on reel one, five on reel two, seven on reel three, and so on, producing a much smaller total for that particular spin. The number displayed on screen during play shows you in real time exactly how many ways to win the current spin holds.
Winning combinations in Megaways do not require symbols to land on a specific payline. Instead, you need matching symbols on consecutive reels starting from the left, regardless of where exactly on each reel they appear. That is what makes the variable reel height work — position on the reel does not matter, only which reel the symbol appears on.
Cascading Reels
Almost all Megaways slots include cascading reels, sometimes called avalanche reels. When a winning combination lands, the symbols that formed it disappear from the reels. New symbols fall down from above to fill the empty spaces. If those new symbols form another winning combination, the process repeats — all within a single paid spin. A strong cascade chain can produce multiple wins from one spin without any additional cost.
Multipliers
Many Megaways games attach a multiplier to the cascade mechanic. Each successive cascade within one spin increases the multiplier by one — so the first cascade might win at 1×, the second at 2×, the third at 3×, and so on. In free spins bonus rounds, these multipliers can grow very large, which is where the biggest wins in Megaways games tend to come from.
Free Spins Bonus Rounds
Megaways games almost always include a free spins feature, usually triggered by landing scatter symbols. The free spins round typically carries an unlimited or growing multiplier that climbs with each cascade, which means a good cascade chain during free spins can produce payouts that dwarf anything possible in the base game. This is the feature most Megaways players are chasing.
How to Play a Megaways Slot
Playing a Megaways slot uses the same basic controls as any other online slot. You set your stake, press spin, and the reels do the rest. The Megaways mechanic runs entirely in the background — you do not need to do anything differently to activate it. The changing reel heights and ways-to-win count happen automatically on every spin.
Check the Paytable First
Before playing any Megaways game, open the information or paytable screen. This tells you the maximum number of ways to win, which symbols pay the most, how the scatter triggers the bonus round, and how the multiplier grows during cascades. Every Megaways title handles these details slightly differently, so a quick read before you start saves confusion later.
Try It in Demo Mode First
Because Megaways games tend to be high volatility — meaning wins can be infrequent even as they can be large — trying the game in free play before committing real money is a sensible first step. Demo mode lets you understand the cascade rhythm, the multiplier structure, and the bonus trigger frequency without any cost. Our guide to casino demo mode explains how to use free play effectively.
Set Your Stake Relative to Your Budget
Megaways games sit near the top of the volatility scale. Dry spells between significant wins or bonus triggers are completely normal. Before you spin for real money, make sure your stake level allows your budget to cover a reasonable number of spins — at least 100 is a sensible target. If your budget only covers 20 or 30 spins at your chosen stake, consider dropping the stake. Our guide to setting a gambling budget covers this in full.
Megaways Volatility and What to Expect
Megaways slots are almost always high volatility games. The combination of variable reels, cascading wins, and growing multipliers means the big potential sits mostly inside the bonus round — and bonus rounds can take many spins to trigger. Between bonus triggers, the base game can produce long stretches without significant wins.
This is not a malfunction or a sign that something is wrong. It is the design working exactly as intended. If you are new to slots or playing with a modest budget, a low or medium volatility slot may suit you better. If you specifically enjoy the anticipation of hunting a large multiplier in a bonus round, Megaways games are built for exactly that experience. You can learn more about how win frequency and payout size interact in our guide to slot volatility.
Megaways and Bonus Wagering
One practical consideration: Megaways slots are high-volatility games, which makes them a risky choice for clearing bonus wagering requirements. A long base-game dry spell can drain a bonus balance before the wagering requirement is met. Low-volatility slots are generally better suited to working through wagering requirements efficiently. Before using a bonus on any Megaways slot, check the casino’s terms carefully — some casinos exclude high-volatility games from bonus play or reduce their wagering contribution percentage. Our guide to wagering requirements explains how those percentages work in practice.
Who Owns the Megaways Mechanic?
Big Time Gaming created and patented the Megaways mechanic, but they have licensed it to dozens of other developers. That is why you see the Megaways label on games from providers such as Pragmatic Play, NetEnt, Blueprint Gaming, Red Tiger, and many others. Each licensed developer adapts the core mechanic to their own theme and feature set, which is why Megaways games can feel quite different from one another despite sharing the same underlying engine.
Big Time Gaming’s most famous in-house Megaways title is Bonanza, released in 2016, which is widely credited with bringing the mechanic to mainstream attention. The licensed catalogue now runs to well over a hundred games.
Responsible Gambling
Megaways games are high-volatility by design. The base game can run through a budget quickly during dry spells, and the excitement of chasing a bonus round can make it tempting to extend sessions beyond what you planned. Set a loss limit and a session time limit before you start, and stick to them regardless of how close to a bonus trigger a game feels.
If gambling feels difficult to control, free support is available worldwide. GamCare (gamcare.org.uk), BeGambleAware (begambleaware.org), and Gamblers Anonymous (gamblersanonymous.org) offer confidential help. We encourage you to find a local service in your own country if one is available.
Megaways slots and all online casino games are available to players in regions where online gambling is permitted. Laws vary by country — always check the regulations that apply where you live.
Frequently Asked Questions
What does Megaways mean in slots?
Megaways is a patented slot mechanic created by Big Time Gaming. It replaces fixed paylines with a variable reel system where the number of symbols on each reel changes randomly on every spin. This creates a constantly shifting number of ways to win, from a few hundred to as many as 117,649 on a standard six-reel game.
How many ways to win do Megaways slots have?
It depends on the specific game, but the most common maximum is 117,649 ways to win — reached when all six reels display their maximum of seven symbols simultaneously. That total is calculated by multiplying the symbol count on each reel: 7 × 7 × 7 × 7 × 7 × 7. The actual ways to win change with every spin.
Are Megaways slots high volatility?
Yes. Most Megaways slots sit at the high end of the volatility scale. The biggest wins tend to come from the free spins bonus round with growing multipliers, which means the base game can produce long stretches without a significant payout. A suitable bankroll relative to your stake is important before playing.
Who invented Megaways?
Australian developer Big Time Gaming created and patented the Megaways mechanic, with Bonanza being the game that brought it to wide public attention in 2016. Big Time Gaming has since licensed the mechanic to dozens of other slot developers, which is why Megaways games appear from many different providers.
What are cascading reels in a Megaways slot?
Cascading reels (also called avalanche reels) are a feature found in nearly all Megaways games. When a winning combination lands, the winning symbols disappear and new ones fall in from above. If the new symbols form another winning combination, the process repeats — meaning a single paid spin can produce multiple consecutive wins. Many Megaways games also increase a multiplier with each cascade.
Can I play Megaways slots for free?
Most Megaways titles are available in free demo mode at online casinos, allowing you to try the mechanic without spending real money. Demo mode is a good way to get a feel for the cascade rhythm and bonus features before playing with real money.
Do all Megaways slots work the same way?
The core mechanic is the same — variable reel heights creating a changing number of ways to win — but individual games differ in their features, maximum ways to win, multiplier structures, and bonus round rules. Always check the paytable of any specific Megaways game before playing.
