What are Megaways slots?
Megaways is a slot mechanic created by Big Time Gaming (BTG) that replaced fixed paylines with a variable-reel system. On each spin, every one of the six reels shows a random number of symbols — usually between two and seven — and the number of ways to win is recalculated accordingly. When every reel lands seven symbols, you get the famous maximum of 117,649 ways to win. It is a completely different feel to a traditional 20-payline slot, and it is why Megaways games have become the most popular slot format in the UK.
BTG licenses the mechanic to other studios, which is why you will find Megaways versions of slots from Pragmatic Play, Blueprint, Red Tiger, Relax Gaming and many more, all alongside BTG's own originals like Bonanza. Our what are Megaways slots guide is the full primer, and how Megaways works goes under the bonnet.
What makes a great Megaways casino
The casinos in the table above are ranked on how well they serve a Megaways player specifically, not on the size of a welcome banner. Four things decide it, and they are what we weight our rankings around.
The size of the Megaways library. A great Megaways casino carries hundreds of titles, not a token handful — the BTG originals, the big Pragmatic and Blueprint releases, and a steady flow of new ones. See casinos with the most Megaways slots.
The studios it carries. Range means little without quality. The best casinos stock every major Megaways studio, so you get the well-built, properly tested versions rather than obscure imitations. Our studios guide explains who makes what.
RTP and fairness. Many Megaways slots ship in multiple RTP versions, and good casinos run the higher ones. Every casino we list is UKGC-licensed, so the games are independently tested. See high RTP Megaways.
Payout reliability. Big Megaways wins are no use if the casino is slow to pay them. We withdraw from every casino we review and rank on what we find. See fast payout Megaways casinos.
How we review and rate Megaways casinos
Our rankings come from hands-on review, not press releases. For each casino we follow the same process so the scores are comparable and fair.
- Check the licence. We confirm a current UKGC licence before anything else. No licence, no listing.
- Count and judge the Megaways library. We look at how many Megaways titles the casino carries, which studios, and whether the big names are present.
- Play the slots. We play the headline Megaways titles on desktop and mobile to judge how well they run and which RTP versions are used.
- Withdraw. We cash out and time it, because a big Megaways win is only as good as the payout behind it.
- Score and rank. We weight library size, studio quality, fairness and payouts into an overall rating. Commission never moves the order.
The full breakdown is in our methodology, and how we rate Megaways casinos explains the weighting in plain English.

Start with the basics
The most popular Megaways slots
Part of choosing a Megaways casino is knowing which titles you want to play. A handful of slots dominate the format, and any casino worth its salt will carry them. Bonanza Megaways is the original — the 2016 BTG release that launched the mechanic, still one of the most played slots in the UK. Fishin' Frenzy Megaways brought the hugely popular Reel Time series into the format, and Big Bass Megaways did the same for Pragmatic's fishing franchise. Classics have been reworked too: Gonzo's Quest Megaways and Rainbow Riches Megaways take much-loved originals and rebuild them around variable reels.
Each plays differently — volatility, features and RTP vary a lot — so it is worth understanding a title before you stake real money on it. Our best Megaways slots page ranks them, and we have dedicated breakdowns of Bonanza, Fishin' Frenzy and Big Bass Megaways.
Why Megaways slots are so volatile
If you have played a few Megaways slots, you will have noticed they tend to swing harder than ordinary slots — long dry spells punctuated by occasional big hits. That is high volatility, and it is baked into the maths of the format. The huge number of ways to win, combined with the cascading reactions and escalating multipliers that most Megaways games use in their bonus rounds, concentrates a lot of the return-to-player into rare, large wins rather than frequent small ones.
That has two practical consequences. First, your balance can drop quickly during a bad run, so a Megaways slot eats through a bankroll faster than a low-volatility game at the same stake — playing at smaller stakes is the sensible way to enjoy them for longer. Second, the headline "max win" figures you see (often 10,000x or more) are genuinely possible but extraordinarily rare, and should never be treated as a realistic target. Our volatility guide explains the maths, and low stake Megaways casinos are the sensible place to start.
Playing Megaways slots safely and in control
Megaways slots are designed to be exciting, and their high volatility is part of the appeal — but it also makes staying in control more important than with a gentler game. The good news is that UK-licensed sites are built with the tools to help, and the best habits cost nothing.
Set a deposit limit before you play — it is the simplest and most effective guardrail there is, and you can lower it instantly at any time. Treat Megaways play as paid entertainment with a fixed budget rather than a way to make money, play at stakes you can comfortably afford given the volatility, and never chase a loss after a bad run, which is the clearest warning sign that play is becoming a problem. Only ever play somewhere showing a valid UKGC licence. If you ever want a complete break, you can block yourself from every licensed UK gambling site at once through GAMSTOP.

Frequently Asked Questions
What are Megaways slots?
Megaways is a slot mechanic by Big Time Gaming where each of the six reels shows a random number of symbols every spin, changing the number of ways to win — up to a maximum of 117,649. It plays very differently to a fixed-payline slot. See our what are Megaways slots guide.
What is the best Megaways casino?
The casino at the top of our table is our current best pick, chosen for the best combination of Megaways library size, studio quality, RTP and payout reliability. For a specific priority, see most Megaways slots or high RTP Megaways.
How many ways to win do Megaways slots have?
Up to 117,649 on a maximum spin, when all six reels land seven symbols. The number changes every spin as the reel heights vary. Our ways to win guide explains where the figure comes from.
Are Megaways slots fair?
Yes. At UK-licensed casinos every Megaways slot runs on an independently tested random number generator that cannot be altered. They carry a house edge, so they are fair but still favour the casino over time. See are Megaways slots rigged.
What RTP do Megaways slots have?
It varies by title and version — typically 94% to 96.5%. Many Megaways slots ship in several RTP versions, and the casino chooses which to run, so the same slot can pay differently in different places. See Megaways RTP explained.
Why are Megaways slots so volatile?
The huge number of ways to win, plus cascading reactions and escalating multipliers, concentrates the return into rare big wins rather than frequent small ones. That makes most Megaways slots high-volatility. See volatility explained.
What is the best Megaways slot?
Bonanza Megaways is the original and still a favourite, but Fishin' Frenzy, Big Bass, Gonzo's Quest and Rainbow Riches Megaways are all hugely popular. It depends on the features and volatility you want. See our best Megaways slots page.
Which studios make Megaways slots?
Big Time Gaming created the mechanic and licenses it to others, so you will find Megaways slots from Pragmatic Play, Blueprint, Red Tiger, Relax Gaming and many more. Our studios guide covers who does what best.
Can I play Megaways slots for free?
Yes — most casinos let you play Megaways slots in free demo mode, a good way to learn a title before staking real money. See our Megaways free play page. Demo mode cannot pay real winnings, of course.
Can I play Megaways slots on my phone?
Yes — though the six reels and fast reactions need a well-built site to run smoothly on mobile. Our mobile Megaways casinos page picks the ones that do it best.
Are Megaways casinos affected by the 2026 UK rules?
The slots are: stakes are capped at £5 a spin (£2 for 18–24s), games must be independently tested, and customer funds are protected. The high ways-to-win count does not change the odds. Our 2026 rules guide covers it.
How do I play Megaways slots responsibly?
Treat them as high-volatility entertainment, not income, play at stakes you can afford through a dry run, set a deposit limit and never chase losses. Free help is on 0808 8020 133, GamCare and BeGambleAware. You can self-exclude via GAMSTOP.
