What Are Megaways Slots and How Do They Work?
Megaways slots are online slots that use a random reel modifier to change the number of symbols on each reel with every spin, creating a variable number of ways to win instead of fixed paylines.
Developed by Big Time Gaming, the most common Megaways format is a six-reel grid, and each reel can show between two and seven symbols. You can calculate the number of possible ways to win by multiplying how many symbols are on each reel.
For example:
- The minimum ways to win in a standard six-reel game: 2 x 2 x 2 x 2 x 2 x 2 = 64
- The maximum ways to win in a standard six-reel game: 7 x 7 x 7 x 7 x 7 x 7 = 117,649
These are ways to win, not paylines — so how do Megaways slots work once the reels come to a stop? To win, matching symbols need to appear on consecutive reels from left to right, but they can usually occupy any visible position on those reels and they don’t need to be touching.
Here’s the Gonzo’s Quest Megaways pay guide for example:
The fun doesn’t stop once you land a winning combination, either. Most Megaways slots use cascading reels, sometimes also called tumbling reels, avalanche reels, or reaction reels depending on the provider. With this mechanic, winning symbols disappear and new ones fall into the empty spaces, potentially creating a chain reaction of wins without requiring another paid spin.
Many Megaways online slots also include a free spins round that’s triggered by landing scatters on the reels. These rounds typically involve an unlimited multiplier ladder that increases after each winning cascade and does not reset between free spins. Usually, this is where the biggest potential wins in Megaways games come from.
Be warned: the combination of variable ways to win, cascading reels, and free spins multipliers make most Megaways slots highly volatile. That makes them better suited to players with larger budgets, as you can often encounter long dry streaks without landing any wins.
Why Do Some Megaways Slots Have Far Fewer Ways to Win?
While the six-reel seven-symbol Megaways format with up to 117,649 ways to win is the most popular, it’s not the only one.
Some games go well above this number, while some are much lower — the maximum ways to win depends entirely on the reel configuration. Christmas Carol Megaways adds an extra horizontal reel across the top of the standard six, resulting in up to 200,704 ways. Eye of Horus Megaways, on the other hand, uses six reels of up to five symbols, capping the possible ways to win at 15,625.
Remember: more ways to win does not automatically mean better value or larger prizes. The RTP, max win, and volatility are what affect payouts, and are separate parts of the game’s mechanics. A slot with 15,625 ways to win can have a higher max payout than one with over 200,000.
Want to check the ways to win during a game? Just multiply the number of visible symbol positions on each reel. For this spin of Eye of Horus Megaways, for example:
- 3 x 5 x 3 x 3 x 3 x 3 = 1,215 ways to win for that spin.
| Grid Configuration | Max Ways to Win | Example Titles |
|---|---|---|
| Six reels, up to five symbols | 15,625 | Eye of Horus Megaways, Fishin’ Frenzy Megaways |
| Five reels, up to seven symbols | 16,807 | Kingmaker Fully Loaded, Luck O’ The Irish Megaways, Reactoonz Blitz |
| Standard six reels, up to seven symbols | 117,649 | Bonanza Megaways, Power of Thor Megaways |
| Six reels plus horizontal reel | 200,704 | Christmas Carol Megaways, Desert Spins Megaways |
| Extended reels (up to twelve symbols) | 248,832 | White Rabbit Megaways |
Why Does the Same Megaways Slot Have a Different RTP at Different Casinos?
Just like other online slots, Megaways games are supplied in several certified RTP versions, meaning they can have different RTPs at different casinos. It’s not a setting you can change as a player; the operator decides which one to run.
Why do Megaways slots have different RTP figures when everything else appears identical? It’s usually a commercial decision. The RTP percentage defines how much a slot pays out on average, and thus the house edge — how much the casino keeps over the long term. As operating costs have increased, we’ve seen casino brands lower RTPs across the board, with many now supplying Megaways slots at around 92%–94% RTP.
UK Gambling Commission rules require the applicable RTP or likelihood-of-winning information is easily available before you gamble. To see which RTP version your casino is serving, open the in-game information screen or paytable before you spin.
Here are some examples of RTP versions. As you can see, the range can vary significantly, with a 96% RTP offering significantly better value than an 88% version. We recommend sticking to higher RTPs wherever possible.
| Megaways Slot | Highest Version | Reduced Versions in Circulation | Gap |
|---|---|---|---|
| Bonanza Megaways | 96% | 94.06% | 1.94 points |
| Extra Chilli Megaways | 96.82% | 94.66%, 91.50% | 5.32 points |
| White Rabbit Megaways | 97.77% | 94.41%, 92.02% | 5.75 points |
| Buffalo King Megaways | 96.52% | 94.51%, 88.51% | 8.01 points |
Highest Paying Megaways Slots: RTP and Max Win Compared
The highest paying Megaways slots fall into two categories: Megaways slots with the highest RTP and Megaways slots with the biggest max win.
Generally speaking, higher-RTP titles have more modest max wins, while those with huge jackpot prizes have an average or lower RTP.
If you want the best long-term returns and overall value for money, go for the highest RTP Megaways slots. If you prefer the thrill of chasing an exceptional payout and don’t mind a bigger house edge, go for the biggest max win.
Something worth knowing: the average Megaways RTP is 96.22% according to Big Time Gaming, so the game format isn’t necessarily any better or worse for winning than regular slots. Below, you can compare some popular Megaways slots based on their highest available RTP, max win, and volatility.
| Megaways Slot | Provider | Highest RTP Version | Max Win | Volatility |
|---|---|---|---|---|
| Madame Mystique Megaways | Pragmatic Play | 98.03% | 5,000x | High |
| Blood Suckers Megaways | Red Tiger | 97.66% | 20,521x | High |
| Primal Megaways | Blueprint Gaming | 96.76% | 50,000x | High |
| Bonanza Megaways | BTG | 96.00% | 26,000x | High |
| Mermaid Queen Megaways | Blueprint Gaming | 94.09% | 250,000x | High |
Megaways Slots List: The Newest Releases
Megaways remains a popular format at UK casinos, with one or two new titles launching each month. Most of these come from Pragmatic Play and Big Time Gaming, but smaller developers like BGaming and Playzia are also licensing the mechanic from BGT to create their own spin on things.
Generally speaking, new Megaways slots feature high volatility and ship with multiple RTP versions that typically top out around 96%. Pragmatic’s The Dog House Megaways 1000 is a notable exception, and is one of the few low volatility Megaways games to arrive in recent years.

Which Providers Make the Best Megaways Slots?
As the inventor of the Megaways format, Big Time Gaming arguably makes the best Megaways slots. It also has the largest catalogue, having launched the first Megaways slot, Dragon Born, at the end of 2015 before Bonanza Megaways propelled the format into the mainstream.
While BGT still releases its own Megaways titles, it also licenses the engine to other studios including:
- NetEnt and Red Tiger create polished Megaways versions of familiar slots like Gonzo’s Quest and Twin Spin Megaways.
- Pragmatic Play pairs the Megaways format with its popular Tumble mechanic and mid-range RTPs.
- Blueprint Gaming is known for its high max win Megaways games.
- Relax Gaming, Inspired, iSoftBet, ReelPlay and other developers have all created their own thrilling Megaways slots, though quality and RTP vary significantly.
Not sure if you’ll enjoy a title? Most UK casinos offer a free demo mode you can use to try before you buy.
How Do UK Rules Change the Way You Play Megaways Slots?
As part of its approach to gambling harm reduction, the UK Gambling Commission has certain rules around online slots, which means they play differently at UKGC licensed casinos than in demo mode or international sites:
- Stake limit
Players aged 25 and over can stake up to £5 per game cycle, while 18-to-24-year-olds are capped at £2 per cycle. In Megaways slots, a full cascade chain counts as one cycle. - Bonus buys are banned
You can’t buy the bonus on Megaways slots UK players can access. While feature buys (often priced at 50x to 100x the sake) may appear in demo or international versions, they’re unavailable for UK real-money play. - Game design
Autoplay, turbo spins, quick spins, and slam stops are banned, with at least 2.5 seconds required between spins. Returns at or below your stake must not receive win-style celebrations. - Session information
Casinos must display your net position (whether you’re up or down) and time played, giving you a clear view of the session.
Remember: these rules are put in place to help keep you safe — you should never play at an unlicensed or offshore casino to circumvent them.

Can You Use a Casino Bonus on Megaways Slots?
Whether Megaways slots can be played with a bonus depends entirely on the offer and operator terms and conditions. While matched deposits are often fairly flexible, free spins bonuses are typically tied to a few specific slot games — though at some brands, this is a Megaways title.
One option is to find a no wagering free spins bonus that pay out real money. That way, if you land some wins on the eligible game, you can then use them as your stake on a Megaways slot.
As always, check the promotion’s full T&Cs before you claim. The UKGC introduced a 10x cap on wagering requirements from 19 January 2026, but game weighting may still vary — Megaways slots may not count 100% towards playthrough.
Responsible Gambling and Megaways Slots
With features like dynamic reels and cascading wins, Megaways slots can be thrilling, but these same mechanics can also increase their addictive quality beyond regular slots.
Remember: each spin is independent of the last. A long run without a win or bonus round does not make one ‘due’.
Since most Megaways games have high variance, dry spells can quickly deplete your bankroll, but due to the Megaways mechanics, sessions can feel eventful even when your balance is decreasing. UKGC rules require operators to display your net position and time played alongside the slot, so use this to gauge how your session is going — not the game’s animations.
All UKGC-licensed casinos must provide safer gambling tools like deposit and loss limits, and reality checks for tracking your session length. We recommend enabling these when you sign up.
If you need to take a break, time-outs can block your account for up to 30 days, or you can self-exclude from all licensed gambling platforms for six months to five years using the free Gamstop service.
