If you’ve spent any time playing online slots in the UK over the past few years, you’ll have run into the Megaways mechanic — probably more than once. What started as a clever bit of engineering by an Australian studio called Big Time Gaming has become one of the most influential ideas in modern slot design, licensed out to dozens of developers and stamped onto hundreds of games.
But here’s the honest truth from someone who has spun through more of these games than I’d care to admit: not all Megaways slots are created equal. Some are genuine classics that changed the industry. Others are lazy reskins riding on the name. This guide separates the two, explains how the mechanic actually works, and helps you play Megaways slots online with realistic expectations.
What Are Megaways Slots?
Megaways is a licensed reel mechanic invented by Big Time Gaming (BTG). Instead of a fixed number of paylines, a Megaways slot changes the number of symbols that land on each reel with every single spin. One spin might show two symbols on a reel; the next might show seven.
Because the number of ways to win is calculated by multiplying the symbols across each reel, the total fluctuates constantly — typically up to a maximum of 117,649 ways (that’s six reels showing seven symbols each, or 7×7×7×7×7×7). Some later titles push this even further, with certain games offering hundreds of thousands or even over a million ways to win.
The result is a spin experience that feels alive. No two spins look the same, and the anticipation of hitting a “full board” of maximum ways is a big part of the appeal.
Most Megaways slots also share a few common features:
- Cascading reels (reactions): winning symbols disappear and new ones tumble down, allowing chains of wins from a single spin.
- Unlimited win multipliers in free spins: in many titles, every cascade during the bonus round increases a multiplier that never resets until the feature ends.
- Bonus buy options: some versions let you purchase the free spins feature directly — though note that bonus buys are banned for UK players under UK Gambling Commission rules, so you won’t see this option at licensed UK casinos.
The Best Megaways Slots to Play in the UK
After years of playing, testing and comparing these games, the following titles stand out. RTP figures listed are the default versions — always check the paytable at your chosen casino, as operators can sometimes select lower-RTP variants.
- Bonanza Megaways (Big Time Gaming)
The one that started it all, and still arguably the best. Released in 2016, Bonanza’s gold-mining theme, “GOLD” scatter mechanic and unlimited win multiplier during free spins set the template that hundreds of games have copied since. With an RTP of around 96%, high volatility, and a max win in the region of 10,000x your stake, it remains the benchmark. If you’ve never played a Megaways slot, start here — it’s the purest expression of what the mechanic can do.
- Extra Chilli Megaways (Big Time Gaming)
BTG’s follow-up to Bonanza, and for many players an improvement. The Mexican street-market theme is vibrant, the extra bottom reel adds more action, and the Feature Drop mechanic (the UK-legal cousin of a bonus buy in its original form has been adapted for compliance) plus a free spins gamble wheel give you more control over your session. It’s fiery in every sense — high volatility with the potential for enormous multiplier chains.
- Gonzo’s Quest Megaways (Red Tiger / NetEnt)
A brilliant example of the licensed mechanic done right. Red Tiger took NetEnt’s beloved original — one of the most famous slots ever made — and rebuilt it with Megaways reels, keeping the Avalanche feature and increasing multipliers. It’s slightly less volatile than BTG’s own titles, which makes it a good middle ground for players who find Bonanza too brutal on the bankroll.
- Fishin’ Frenzy Megaways (Blueprint Gaming)
Blueprint has licensed Megaways more enthusiastically than anyone, and Fishin’ Frenzy Megaways is its biggest hit with UK players. The fisherman-collects-fish-values bonus round is simple, familiar and satisfying. It’s lower-intensity than most games on this list, which is exactly why it’s so popular in the UK market — sometimes you want a relaxed session rather than a white-knuckle ride.
- Buffalo Rising Megaways (Blueprint Gaming)
A stampede-themed slot with cascading wins and an unlimited multiplier in free spins. It plays similarly to Bonanza but with its own character, and the mystery symbol feature can produce sudden, dramatic wins. A solid choice if you love the Bonanza formula but want a change of scenery.
- Piggy Riches Megaways (Red Tiger / NetEnt)
Another successful modernisation of a NetEnt classic. The free spins feature — where you pick your combination of spins and starting multiplier — adds a genuine strategic choice that most slots lack. Do you take more spins with a lower multiplier, or gamble on fewer spins that hit harder? That decision keeps the game interesting long after the novelty wears off.
- Rick and Morty Megaways (Blueprint Gaming)
Proof that branded slots don’t have to be cynical cash-grabs. The show’s humour actually comes through in the features, with multiple modifiers and bonus rounds. Volatility is more moderate here, and the entertainment value per spin is genuinely high.
- White Rabbit Megaways (Big Time Gaming)
Technically an “expanding reels” cousin of the core mechanic, White Rabbit lets reels grow during the bonus round to a staggering 248,832 ways to win. The Alice in Wonderland theme is beautifully executed, and the caterpillar wilds and reel-extending rabbit symbols make the free spins round one of the most engaging in the genre.
How to Choose the Right Megaways Slot for You
With hundreds of Megaways titles available at UK casinos, a bit of self-awareness goes a long way. Here’s what I’d weigh up:
Volatility. Most Megaways slots are high volatility, meaning long dry spells punctuated by occasionally large wins. If that pattern frustrates you, look at gentler options like Fishin’ Frenzy Megaways rather than BTG’s flagship titles. Your bankroll needs to match the game’s temperament.
RTP (Return to Player). The theoretical percentage a game returns over the long run. Most quality Megaways slots sit around 95.5–96.5%. Crucially, some providers offer multiple RTP versions of the same game, and the casino chooses which to run. Check the in-game paytable every time — it takes ten seconds and it’s the single most useful habit a slots player can have.
Max win potential. Games like Bonanza and Extra Chilli can theoretically pay tens of thousands of times your stake. But higher ceilings usually mean higher volatility. Decide whether you’re chasing a dream or chasing entertainment.
Feature design. Do you want unlimited multipliers (Bonanza, Buffalo Rising), collect-style bonuses (Fishin’ Frenzy), or player choice (Piggy Riches)? The bonus round is where Megaways slots differentiate themselves, so pick the mechanic that suits your taste.
Playing Megaways Slots Online Safely in the UK
This part matters more than any game recommendation, so please don’t skip it.
Only play at UKGC-licensed casinos. The UK Gambling Commission licence guarantees the games are independently tested, your funds are protected, and you have access to dispute resolution. The licence details should be displayed in the casino’s footer — verify them on the Gambling Commission’s public register if you’re ever unsure. Unlicensed offshore sites offering “bonus buys” or crypto play to UK customers are not worth the risk, full stop.
Understand the UK-specific rules. Since 2021, UK-licensed slots have no autoplay, no bonus buy features, mandatory spin speed limits (each spin takes at least 2.5 seconds), and no celebration effects for wins smaller than your stake. Some players grumble about these changes, but they exist to reduce harm, and the games remain fully playable.
Set limits before you start. Every UKGC casino must offer deposit limits, loss limits, time-outs and self-exclusion. Use them proactively, not reactively. Decide what a session is worth to you as entertainment — because that’s what slots are, entertainment with a cost, not an income strategy.
Know the maths. No strategy, betting pattern or “hot streak” changes a slot’s RTP. Every spin is independent and determined by a random number generator. Megaways slots are wonderful entertainment, but the house edge is real and permanent.
FAQs
What does 117,649 ways to win mean? It’s the maximum number of winning combinations possible when all six reels show seven symbols each. Matching symbols on adjacent reels from left to right, in any position, creates a win.
Are Megaways slots better than regular slots? Not objectively — RTP is what determines long-term returns, not the mechanic. But many players find the variable reels and cascading wins more engaging than fixed-payline games.
Can I play Megaways slots for free? Yes, most UK casinos offer demo modes once you’re registered and verified, letting you learn a game’s rhythm before staking real money. It’s a sensible habit.
Why can’t I buy the bonus feature in the UK? The UK Gambling Commission banned feature buy-ins at licensed operators because they dramatically increase the cost and speed of play. If a site offers you a bonus buy, it isn’t UK-licensed — walk away.
Which Megaways slot has the best RTP? It varies by casino because of multiple RTP versions, but the default versions of Bonanza and Extra Chilli (around 96%+) are among the strongest. Always confirm in the paytable.
Final Thoughts
The Megaways mechanic earned its dominance honestly: it made slots less predictable and more exciting to watch. Bonanza and Extra Chilli remain the gold standard, Gonzo’s Quest and Piggy Riches show how classics can be reinvented, and Blueprint’s catalogue offers something for gentler tastes. Pick games that match your volatility tolerance, check the RTP every time, stick to UKGC-licensed sites, and treat every session as paid entertainment with a firm budget.
Spin smart, and enjoy the ride.
