Category Overview
What Megaways Actually Is
Megaways is a slot game mechanic patented by Big Time Gaming (BTG), an Australian studio acquired by Evolution in 2021. The mechanic produces a variable number of symbols on each reel for every spin, generating anywhere between 324 and 117,649 ways to win on the standard 6-reel version. The variability is what makes the mechanic distinctive — every spin looks different.
The first Megaways slot was Dragon Born in 2015. The breakthrough hit was Bonanza (2016), still one of the most-played Megaways titles in the UK. BTG licenses the engine to other studios, so today Megaways slots exist from Pragmatic Play, Blueprint, Red Tiger, iSoftBet, Relax Gaming, ReelPlay, and dozens of others — all paying a royalty to BTG and following the underlying mathematical framework.
The Best UK Slot Sites for Megaways Variety
Casumo leads our comparison on Megaways depth at 145+ titles — the broadest selection from any UK operator. Ladbrokes follows at 85+ and Coral at 75+. The combination of catalogue depth and provider diversity is what separates the leaders. A site with 80 Megaways titles all from one provider is less useful than a site with 70 spread across BTG, Pragmatic, Blueprint and Red Tiger.
Megaways Volatility
Megaways slots run high-volatility by design. The variable reel structure produces big swings — long dead spells punctuated by occasional huge wins in the bonus round. Bonanza Megaways tops out at 12,000x bet, Sweet Bonanza Megaways at 21,000x bet, Money Train 4 (not strictly Megaways but the same volatility class) at 150,000x bet. Bankroll management is non-negotiable when playing this category — set strict session limits and stick to them.
Bonus Buy Restrictions in the UK
Many Megaways slots include a "bonus buy" feature in their non-UK versions, allowing players to pay 70x–100x bet to instantly enter the bonus round. UK Megaways slots have these features disabled by UKGC rule. You can still enter the bonus round through normal play, but you cannot buy direct entry on a UK-licensed site. Some Megaways slots are also released in modified-RTP "UK-compliant" versions, so verify the RTP on screen before committing to a session.

Frequently Asked Questions about Megaways Slot Sites
What does Megaways mean?
Megaways is a slot game engine that produces a variable number of symbols on each reel for every spin, generating anywhere between 324 and 117,649 ways to win on the standard 6-reel layout. The variability is what makes it distinctive — every spin produces a different reel structure. Read the full Megaways guide.
Who invented Megaways?
Big Time Gaming (BTG), an Australian studio that launched the first Megaways slot (Dragon Born) in 2015. BTG was acquired by Evolution Gaming in 2021 and licenses the Megaways engine to other studios — so today Megaways slots exist from Pragmatic Play, Blueprint Gaming, Red Tiger, Relax Gaming and many others, all paying royalties to BTG.
How many ways to win can a Megaways slot have?
Standard 6-reel Megaways slots top out at 117,649 ways (7^6). Some variants with carriage reels or extended structures exceed this — White Rabbit Megaways tops out at 248,832 ways. The actual number on any given spin depends on how many symbols land on each reel (typically 2 to 7 per reel).
Are Megaways slots high or low volatility?
Almost all Megaways slots are high or very-high volatility by design. The variable reel structure produces big swings — long dead spells punctuated by occasional huge wins, almost always in the bonus round. Plan your bankroll accordingly. Volatility guide here.
What is the best Megaways slot for beginners?
Bonanza Megaways (the original, BTG, 96.00% RTP) and Dog House Megaways (Pragmatic Play, 96.55% RTP) are the most accessible entry points — both have clear bonus mechanics, manageable volatility for the category, and broad UK availability. Read our Bonanza Megaways review.
Are bonus buys allowed on UK Megaways slots?
No. The UKGC requires bonus buy features to be disabled on UK-facing slots because they were judged to encourage harmful play patterns. You can still trigger the bonus round through normal play, but you cannot pay to enter on a UK-licensed site. Some Megaways slots are also released in modified-RTP "UK-compliant" versions — verify on screen.
Which UK slot site has the most Megaways games?
Casumo leads our comparison at 145+ Megaways titles — the broadest selection of any UK operator. Ladbrokes follows at 85+ and Coral at 75+. Read the Casumo review.
Do Megaways slots have higher RTP than standard slots?
Not systematically. Most Megaways slots sit in the 95.5–96.5% RTP band — similar to mainstream non-Megaways slots. Some are higher (White Rabbit at 97.39%) and some are lower. Multi-RTP variants exist on some titles, so the same Megaways slot can run at different RTPs on different sites — check on screen.
Can I play Megaways slots on mobile?
Yes — every Megaways slot is built mobile-first these days, with portrait orientations and touch-optimised controls. Performance on older phones can be patchy because of the visual complexity, but any phone from the last four years handles them comfortably.
What is the highest-paying Megaways slot?
By maximum win multiplier, Sweet Bonanza Megaways tops out at 21,000x stake, Money Train 4 (extreme-volatility, same class) at 150,000x, and White Rabbit Megaways at 17,000x. By RTP, White Rabbit at 97.39% leads. Maximum win is theoretical — these outcomes are very rare.
