Most slots are built on a fixed grid. Five reels, three rows, the same paylines on every spin. Megaways threw that out. On a Megaways slot, each reel shows a different number of symbols every spin, so the number of ways to win changes too, from a few hundred on one spin to more than 100,000 on the next. Add cascading wins and, on many titles, a multiplier that keeps climbing through the free spins, and you get some of the most volatile and most played slots in Canada.
This page explains how the mechanic actually works, what it does to your chances and your bankroll, which titles are worth knowing, and how to play Megaways slots for real money at Canadian casinos.
Quick answer: Megaways is a reel system licensed from Big Time Gaming in which each reel shows between two and seven symbols per spin, giving up to 117,649 ways to win on the standard layout. Most Megaways slots publish an RTP around 96% and play as high volatility, so expect long quiet spells and occasional large wins. Check the RTP on the game’s info screen before you play, and size your bets for the swings.

About this list. These are our general picks for players outside Ontario and Alberta, ranked by our overall review score. All carry Megaways titles from several studios, but libraries change, so search for the game you want before you deposit. If you live in Ontario or Alberta, play at a provincially licensed site instead (see the section on provincial sites further down).
How Megaways Slots Work
A standard video slot pays along fixed lines or a fixed number of “ways”. A Megaways slot recalculates the ways on every spin:
- Reels change height. On each spin, every reel shows a random number of symbols, usually between two and seven.
- Ways are multiplied together. The number of ways to win is the number of symbols on each reel multiplied together. Six reels showing 7, 7, 7, 7, 7 and 7 symbols give 7 x 7 x 7 x 7 x 7 x 7 = 117,649 ways. Six reels of two give just 64.
- Wins pay left to right on adjacent reels. Like other ways slots, matching symbols only need to appear anywhere on consecutive reels starting from the left.
- Extra reels on top. Many titles add a horizontal reel above the middle four reels, which adds symbols and therefore ways.
The ways number on screen looks dramatic, but it is not a measure of how likely you are to win. The game’s maths is balanced around it. A 117,649-way spin is not paying more on average than a 64-way spin once the symbol weightings are taken into account. What the changing grid does is make each spin feel different, and leave room for very large combinations when the reels line up.
The Features That Define Megaways Games
Cascading Reels
Big Time Gaming calls them Reactions; other studios use Tumble or Avalanche. Winning symbols disappear, new ones drop in, and the grid can pay again from a single paid spin. Most Megaways slots use them.
Unlimited Win Multipliers
The signature feature of many Megaways bonus rounds. In Bonanza, for example, the multiplier rises by one with every cascade during the free spins and never resets within the feature. This is where Megaways games produce their biggest wins, and why the free spins carry so much of a game’s total return.
Mystery Symbols and Modifiers
Many titles add symbols that transform into a matching symbol, wilds that land with multipliers, or random modifiers before a spin. Each studio adds its own twist on top of the core reel system.
Free Spins With Extra Spins Per Scatter
Free spins usually start from four scatters, with extra spins for each additional scatter. A few titles let you gamble the number of spins on a wheel before the feature starts.
Bonus Buy
Many Megaways games let you pay a fixed multiple of your stake to go straight to the free spins. It is popular, expensive and not available everywhere. Our page on bonus buy slots explains the costs and the rules.
Popular Megaways Slots and Their Published RTP
These are well-known Megaways titles with the RTP their developers publish. Several studios let casinos choose from more than one RTP version of the same game, so the figure at your casino can be lower. The game’s info or paytable screen shows the version you are playing.
| Slot | Studio | Published RTP | What stands out |
|---|---|---|---|
| Bonanza Megaways | Big Time Gaming | 96.00% | The original hit; unlimited multiplier on free spins |
| Extra Chilli Megaways | Big Time Gaming | 96.19% | Gamble wheel for extra free spins |
| Madame Destiny Megaways | Pragmatic Play | 96.56% | Fortune-teller theme with tumbling reels |
| Great Rhino Megaways | Pragmatic Play | 96.48% | Safari theme with tumbling reels |
| Wheel of Fortune Megaways | IGT | 96.46% | A classic brand moved onto Megaways reels |
| Buffalo Rising Megaways | Blueprint Gaming | 96.5% | Buffalo theme, high volatility |
| Temple Tumble Megaways | Relax Gaming | 96.25% | Destructible blocks that open up the grid |
| Gonzo’s Quest Megaways | Red Tiger | 96% | The NetEnt classic rebuilt with Megaways reels |
The pattern is clear: Megaways RTPs cluster tightly around 96%. That is a solid figure for a modern video slot, but it is not where the highest returns are. Older classic-style games such as Blood Suckers publish 98%, and our breakdown of high RTP slots covers that end of the market.
Megaways Volatility: Plan for the Swings
Almost every Megaways slot plays as high volatility. The game spends long stretches paying small amounts or nothing, then occasionally lands a cascade chain or a free spins round with a big multiplier. That has practical consequences:
- Bet smaller than you would on a steady game. If you would play C$1 a spin on Starburst, consider C$0.40 to C$0.50 on a Megaways title for the same session length.
- Expect the free spins to be rare. On many titles, a hundred or more spins between features is normal.
- Judge a game over hundreds of spins, not twenty. A short session tells you almost nothing about a high-volatility slot.
The cost over time follows RTP, not volatility. At C$1 a spin, 500 spins on a 96% game cost about C$20 on average. Volatility decides how far your result can land from that average. Our page on high volatility slots goes deeper on bankroll sizing, and if you want the opposite experience, see our picks of low volatility slots.
Megaways vs Other Slot Formats
| Megaways | Fixed paylines (classic and video) | Cluster pays | |
|---|---|---|---|
| Grid | Changes every spin | Fixed | Fixed, often 6×5 or 7×7 |
| How wins form | Matching symbols on adjacent reels from the left | Symbols along set lines | Groups of touching symbols |
| Typical volatility | High | Low to high | Medium to high |
| Typical RTP | Around 96% | 94% to 98%+, depending on the game | Around 96% |
Our overview of five-reel video slots covers fixed-line and cluster games, and our comparison of classic and video slot formats explains why RTP tends to split the way it does between them.
Megaways Slots and Casino Bonuses
Slots usually count 100% toward bonus wagering, Megaways included. Two things deserve care:
- Volatility and wagering do not mix well. A high-volatility game can wipe out a bonus balance long before the wagering is finished, or land a big win early. If clearing the bonus is the goal, a steadier game is the safer choice. Our explainer on welcome bonus wagering shows the maths.
- Maximum bet rules. Most bonuses cap your stake while wagering, often at C$5 a spin. Winawin’s terms, for example, set C$7.50 per spin and say the cap includes bonus buys. Buying a feature while a bonus is active almost always breaks this rule.
Free spins offers are often tied to a named slot, and Big Bass Bonanza and Book of Dead are more common than Megaways titles. Our list of free spins deposit offers shows which games each casino uses.
Where to Play Megaways Slots in Canada
Megaways games are everywhere now, but some libraries are deeper than others. In Ontario, 888 Casino carries Megaways titles alongside its exclusives, and our list of AGCO-licensed Ontario casinos covers the rest of the market. Ontario-facing sites generally do not offer the bonus buy option, even on games that have it elsewhere. Alberta’s regulated market opened on July 13, 2026, and our page on licensed Alberta casinos tracks the brands that are live.
For the rest of Canada, Lucky Spins lists Megaways among more than 3,000 slots, Casilime and SlotsMagic have Megaways sections, and TonyBet has a deep run of Megaways and bonus-buy titles. Our main roundup of online slots in Canada compares slot sites more broadly.
Tips for Playing Megaways Slots
- Play the demo first. Most Megaways games have a free version with the same maths, and our collection of free slots to play in Canada is a good place to try the format.
- Check the RTP on the info screen. If a game shows a figure well below the published one, play something else.
- Size your bet for 200 spins or more. High volatility needs room.
- Decide in advance what a good result looks like. A big cascade is the moment many players give the money straight back.
- Set a time limit as well as a money limit. The fast cascades make sessions run long.
None of this changes the house edge, and our breakdown of what actually helps at slots explains why. Megaways games are certified like any other slot, and our explainer on whether online slots are rigged shows how that testing works.
How We Assess Megaways Casinos
We look at the number of studios a casino carries, whether game RTPs are visible before you play, how bonus terms treat high-volatility play and feature buys, and how quickly real slot wins are paid out. The full criteria are in our casino review methodology.
Keep the Swings in Proportion
Megaways slots are designed around big moments, which makes it easy to keep spinning for the next one. Set a deposit limit, take breaks, and never raise your stake to win back a loss. If gambling is causing problems, our page on responsible gambling help in Canada lists support in every province.

Do more ways mean a better chance of winning?
No. The game’s maths is balanced across all reel sizes, so a spin with more ways does not pay more on average. More ways mainly create the room for large combinations.
What is the RTP of Megaways slots?
Most popular titles publish an RTP between about 96% and 96.6%. Casinos can sometimes offer lower versions, so check the game’s info screen.
Are Megaways slots high volatility?
Almost all of them. Expect long stretches with small or no wins, broken up by occasional large cascades or free spins rounds.
What was the first popular Megaways slot?
Bonanza by Big Time Gaming made the mechanic famous and is still the reference point for the format. Big Time Gaming now licenses Megaways to many other studios.
Can I play Megaways slots for free?
Yes. Most Megaways titles have a demo mode at the casino or on the developer’s site, with the same maths as the real money version.
