Megaways casino guide: how Megaways slots work and where to play them

Megaways casino games: what makes a slot Megaways

A Megaways casino is simply a casino whose lobby carries slots built on one particular reel engine. Big Time Gaming describes Megaways as the slot mechanic it created, and the studio licenses that engine to other providers. That is why you find Megaways games from many different studios, often sitting right next to an older game with the same name and theme.

The idea is easy to grasp once you see it. On a classic slot, each reel shows a fixed number of symbols and wins are paid along set paylines. On a Megaways slot, each reel shows a random number of symbols on every spin. A reel might hold two tall symbols on one spin and a stack of small ones on the next. Because the reel heights change, the number of possible winning combinations, the ways, changes with every spin too.

Wins are counted on adjacent reels from left to right, and a symbol only needs to appear somewhere on each reel in the run. There are no lines to follow. That is what makes megaways slot games feel so busy: plenty of small symbols, plenty of connections and a ways counter that jumps around from spin to spin.

You will see headline figures for the maximum number of ways quoted all over the internet. We don’t repeat them, because the maximum depends on the game and the numbers in circulation come from trade press rather than a provider page we could check. Every Megaways game states its own figure in the info screen, so read it there.

How the ways count works: a worked example

Here is a hypothetical six-reel spin to show the maths. The reels land 2, 3, 4, 3, 2 and 5 symbols. Multiply them together and you get 2 × 3 × 4 × 3 × 2 × 5 = 720 ways for that spin. On the next spin the reels land 5, 6, 4, 6, 5 and 4 symbols, and the same sum gives 14,400 ways. Your stake did not change; only the reel heights did.

Now a win. Say the first reel shows two kings, the second shows one and the third shows three, while the fourth has none. That is 2 × 1 × 3 = 6 separate three-of-a-kind king wins, each paid at the paytable value for three kings at your stake. This is why stacks of one symbol on the first reels matter so much in online megaways slots: a tall run of the same symbol multiplies the number of ways it can connect.

In practice, more ways does not mean more money on every spin. A spin with a huge ways count can still pay nothing, and a modest one can land a decent hit if a high-paying symbol stacks across the first three reels. The ways counter describes the spin; it does not forecast it. What it does explain is why these games produce such a wide spread of results.

• The ways count is the number of symbols on each reel multiplied together
• Wins run left to right on adjacent reels; there are no paylines
• Several copies of one symbol on a reel multiply its winning ways
• Some games add a horizontal reel above the main reels, which puts extra symbols on some reels
• The maximum ways for a title is printed in its own info screen

Cascades, free spins and growing multipliers

Most megaways games pair the reel engine with cascades, also called tumbles or reactions. When a spin wins, the winning symbols disappear, the ones above drop down and new symbols fall into the gaps. If the new layout wins again it cascades again, and the chain carries on until a drop produces nothing. One paid spin can therefore deliver several wins in a row, and every cascade can change the ways count, because the replacement symbols arrive in different sizes.

The free spins round is where the mechanic does its heavy lifting. In many Megaways games a win multiplier rises with each cascade during free spins, and in some it keeps climbing until the round ends. A hypothetical example: you play at €0.40, and a cascade chain in the bonus pays €0.60, €1 and €0.80 at multipliers of x4, x5 and x6. That chain is worth €2.40 + €5 + €4.80 = €12.20. The same three wins without a multiplier would have paid €2.40.

Other common extras include mystery symbols that all turn into the same symbol, wilds that land with their own multiplier and retriggers that add more free spins. Each game mixes them differently, and the rules screen spells out exactly what yours does. Pay-anywhere games such as Gates of Olympus use tumbling reels too, but they are not Megaways: there are no ways at all, only groups of matching symbols anywhere on screen.

Megaways volatility and RTP: what the swings mean for your money

Volatility describes how a game spreads its returns: often and small, or rarely and large. Megaways slots tend to sit at the swingy end, because so much of their value is packed into free spins with multipliers. Providers don’t always print a volatility rating, so read the info screen and, if it says nothing, judge from a few hundred spins in demo mode. Our free slots guide explains how to run that test properly.

RTP, return to player, is the share of all stakes a game pays back over a very long run. Many Megaways titles exist in several RTP versions, and the casino picks the one it runs, so two lobbies can show the same game with different returns. When people ask about the best paying megaways slots, the honest answer is the version with the highest RTP in your lobby, which you can only confirm in that lobby. Our best payout casino guide covers RTP in more depth.

The gap between versions adds up. On €1,000 of total spins, a 96% version returns €960 on average and a 94% version €940, a €20 difference that comes straight out of your play. It also pays to count spins before you start. Swingy games need room, and the table shows how quickly a budget turns into a short session when the stake creeps up.

Bonus buys deserve a separate note. Many Megaways games let you pay a set multiple of your stake to go straight to free spins. If a feature hypothetically costs 100x and you play at €0.50, each buy is €50, the whole budget below in one click. In demo mode you can buy it twenty times for nothing and see how often it pays back its price.

Popular Megaways styles: from Bonanza to Irish riches

Because the engine is licensed, Megaways has spread across almost every slot theme. Some games were built for it from scratch; many more are Megaways editions of hits that started life as ordinary slots. Grouping them by style helps more than a list of names, because games in the same style tend to pay in similar ways.

Bonanza Megaways is the gold-mine game many players mean when they say Megaways. Searches for bonanza megaways casinos, the Bonanza Megaways slot and big bonanza megaways keep it among the most asked-about games, and its cascades and free spins multiplier show the pattern in its plainest form. Fruit remakes such as Fruit Shop Megaways and Twin Spin Megaways take older, gentler games and give them the changing reels; Big Top Bonanza Megaways brings a circus theme to the same idea.

Remakes of famous slots make up a big group. Gonzo’s Quest Megaways, The Dog House Megaways, Buffalo King Megaways and Madame Destiny Megaways keep the look of the original but change the maths, so never assume the RTP or features carry over. The same goes for the Megaways edition of Big Bass Bonanza. TV and character tie-ins such as Deal or No Deal Megaways and TED Megaways, plus Eye of Horus Megaways, layer themed bonus features over the reels.

Then there are the Irish games. Irish megaways titles such as Rainbow Riches Megaways and Irish Riches Megaways bring leprechauns, rainbows and pots of gold to the changing reels, while Dynamite Riches Megaways and Tiki Treasures Megaways do the same for mining and island themes. If you like a theme, try both the classic and the Megaways version in demo mode: they can feel like two different games.

Best Megaways slots: how to choose the right one

Lists of the best megaways slots usually rank by hype or by the biggest headline win. We prefer criteria you can check yourself in a couple of minutes, because the best Megaways game for a €20 Friday-night budget is not the best one for a high roller.

Run two or three candidates through demo mode with the same stake and the same number of spins, then compare notes. Which one triggered its bonus? How long were the dry spells? Which one could you follow on your phone? That gives you a better shortlist of the best megaways slots to play than any ranking, because it is built around your own budget. For games beyond this mechanic, our best online slots in Ireland picks follow the same rules.

New megaways slots arrive all the time, often as a Megaways edition of a game that already sold well. New is not the same as better. Check the RTP version, read the feature rules and give it a demo run before you trust it with real money.

• RTP: the highest version you can find, as stated in your lobby’s info screen
• Bonus trigger: how many scatters it takes and whether retriggers are possible
• Multiplier rules: does the free spins multiplier reset or keep climbing?
• Bet range: a minimum stake low enough for your budget
• Bonus buy: if there is one, its price as a multiple of your stake
• Mobile layout: six busy reels must stay readable on your phone

How to play Megaways slots online for real money

Once a game passes the demo test, moving to real money is straightforward. The order below keeps the decisions in the right place: budget first, game second, deposit last.

Two notes on bonuses. Welcome offers usually carry wagering, and some casinos exclude certain slots or bonus buys while a bonus is active, so read the game list in the terms before you play megaways with bonus money. Our welcome bonus guide shows how to read those terms. Megaways jackpot games exist as well: some titles add a fixed or progressive jackpot on top of the reels, which changes the maths again. Our guide to jackpot slots explains how those prize pools work.

Megaways games are built for phones, but six reels of changing symbols are a lot for a small screen, and many play better in landscape. Our mobile casino guide covers the practical side of playing on iPhone and Android, from data use to battery.

1. Set a budget and a stakeDecide what you can spend this month, then pick a stake that gives you a couple of hundred spins, for example €0.20 from a €50 budget.

5. Find the game and check the versionSearch the lobby, open the info screen and compare the RTP with the figure you noted in demo mode.
6. Spin, then stop at your limitKeep to your stake, leave bonus buys aside unless you budgeted for them, and stop when the money or the time is up.

Playing at a Megaways casino in Ireland

Ireland’s regulator, the Gambling Regulatory Authority of Ireland (GRAI), began licensing remote betting from 1 July 2026, but applications for gaming licences, which cover casino slots, are only due to open throughout 2027 and 2028. As of October 2026, no megaways casino serves Irish players under an Irish casino licence. Weigh that before you deposit, and read the operator’s terms on withdrawals and complaints.

Our real-money pick is 22BET, an offshore operator without a GRAI licence. It runs casino, live casino and sportsbook on one account and takes debit cards, e-wallets and crypto. The welcome offer is +250% on your deposit, and players rate 22BET 5.0 from 2,748 reviews. Use the lobby search to confirm the Megaways title you want is there, and check the bonus terms on the 22BET site for any game exclusions.

Whatever the casino, decide your limits before the first spin. Megaways sessions can swing hard in both directions, and a long cascade chain is exactly the kind of moment that tempts you to raise the stake. Keep it where you set it. If the sessions start running longer than you planned, our responsible gambling page lists free Irish support lines.
