Medusa Megaways slot: the basics
Medusa Megaways comes from NextGen, a studio with a long run of Greek-mythology games, including earlier Medusa-themed slots. This version takes the Gorgon of legend, whose gaze turned onlookers to stone, and places her on a Megaways reel set. It sits naturally among our Greek mythology slots, next to games such as Gates of Olympus and Rise of Olympus.
The game's identity comes from its maths rather than its art: a reel set whose size changes on every spin, a high-volatility profile and a top prize 50,000 times the stake. Browse other titles on our slot games hub.
How Megaways works on the Medusa Megaways slot machine
The number of ways is the count of symbols on each reel multiplied together. At the maximum of seven symbols on all six reels (counting the top reel where it adds symbols), that's 7 × 7 × 7 × 7 × 7 × 7 = 117,649.

More ways don't change your stake: the total bet is the same whatever the reel heights. They change how many combinations count, which is why wins can look very different from one spin to the next. Megaways vs 243 ways compares the two approaches.
What happens on a Medusa Megaways spin
Set the stake: up to £5 a spin at 25 and over, or £2 at 18 to 24.
Spin. The RNG picks the height of every reel and every symbol on it.
The game reads all the ways from left to right and pays matches from the paytable.
Any extra steps the rules describe, such as winning symbols being replaced, play out inside the same spin.
Scatter symbols are counted; enough of them start the free spins round.
Wins go to your balance and your net position updates on screen.
Every step, including the reel heights, comes from one result chosen by the random number generator when you press spin.
Medusa Megaways free spins and bonus features
Scatter symbols start the free spins round, which is where most of the high-end return is found in a game like this. Megaways titles commonly pair the reel engine with cascading reels and a multiplier during free spins, but versions differ. Published descriptions of this game's extras are inconsistent, so we don't list them; the help screen sets out exactly what Medusa Megaways includes, how many spins are awarded and whether the round can be retriggered.
Medusa Megaways RTP and what it costs
The RTP is 96.28%, which means a house edge of 3.72%: on average, £3.72 of every £100 staked is kept. That average only emerges over a vast number of spins. Some sources list higher settings as well, so the version at your casino could differ; check its rules. RTP explained covers how the figure is worked out.

On a high-volatility Megaways game the result of 100 spins can be far from these averages. Most sessions lose more; a few return much more. Our slot cost calculator lets you try other stakes and spin counts.

The Gambling Commission's online slots stake limit guidance (opens in a new tab) caps stakes at £5 for players aged 25 and over and £2 for 18 to 24-year-olds. A 50,000x result needs an extraordinary combination of ways and multipliers; very few players will ever see it. Max win caps explains how ceilings are enforced.
Is the Medusa Megaways slot worth playing?
Advantages
Up to 117,649 ways gives plenty of variety between spins.
50,000x ceiling, among the higher caps for Megaways games.
RTP of 96.28% is in the normal range.
Drawbacks
High volatility: losing runs are common.
Feature details vary in published descriptions, so you must read the rules.
Busy reel display can make wins harder to follow on a small screen.
It suits adults who enjoy Megaways and myth themes and accept that most sessions will lose. If a smaller cap and steadier play appeal more, look at medium-volatility slot machines instead.
Since 31 October 2021, UK online slots must not offer autoplay, turbo or slam-stop, must take at least 2.5 seconds per spin, must show net position and must not celebrate a return equal to or below the stake. Feature buy isn't supplied to Great Britain, so free spins come only from scatters; see bonus buy in the UK. Free demo play is available after age verification, and credit cards can't be used to gamble.

Frequently asked questions
What is the Medusa Megaways RTP?
Medusa Megaways has an RTP of 96.28%. Over millions of spins, £96.28 comes back for every £100 staked and £3.72 is kept as the house edge. One session can land far from that average, especially on a high-volatility game. Some sources list other settings, so open the rules at your casino and confirm the figure. Our page on what is a good RTP for a slot? explains how to judge it.
What is the Medusa Megaways max win?
The maximum win is 50,000 times the stake. That's £5,000 at 10p, £50,000 at £1, £100,000 at the £2 limit for 18 to 24-year-olds and £250,000 at the £5 limit for players aged 25 and over. Once the cap is reached, the game stops paying. It's an extremely rare outcome. Our answer to what slot has the biggest max win? shows how 50,000x compares.
How many ways to win does Medusa Megaways have?
Medusa Megaways has up to 117,649 ways to win. Each of its six reels shows a random number of symbols on every spin, and the ways count is those numbers multiplied together. At the maximum of seven symbols per reel that's 117,649; with smaller reels, it's far fewer. Your stake stays the same either way. Our Megaways slot machines guide explains the mechanic in full.
Who makes Medusa Megaways?
NextGen makes Medusa Megaways. The studio has produced a series of Greek-mythology slots, including earlier Medusa games, and this version applies the Megaways engine licensed from Big Time Gaming. Because Megaways is licensed, you'll find the mechanic across many studios' games, each with its own maths. The answer to who makes online slots? explains how studios, licensors and casinos fit together.
How do free spins work on Medusa Megaways?
Free spins start when enough scatter symbols land in a spin. The round is where most of the game's high-end potential sits, typically through multipliers applied to wins. The exact number of scatters needed, spins awarded, multiplier rules and retrigger conditions are listed in the help screen for the version you're playing. You can't buy the round in the UK. Read how do free spins work on slot machines? for the general picture.
Can I play the Medusa Megaways demo?
Yes, many UK-licensed casinos offer free demo play of Medusa Megaways after age verification, which has been required for free-to-play games in Great Britain since May 2019. The demo follows the same rules as the real game, so it's useful for seeing how the reels and free spins work. A few hundred demo spins won't tell you much about real-money results. Our demo slots guide explains why.
Is Medusa Megaways high volatility?
Yes, it's rated high volatility. That means long runs with little or nothing back and a return concentrated in rare, larger outcomes, mostly in free spins. A £25 budget at 25p a spin covers 100 spins if nothing comes back, and a run like that is quite possible. The guide to high-volatility slot machines explains how to judge whether that suits your budget.
Is Medusa Megaways the same as Bonanza Megaways?
No, they're different games that share the Megaways engine. Bonanza Megaways was Big Time Gaming's original, released in December 2016 with a 96.00% RTP; Medusa Megaways is NextGen's own game with a 96.28% RTP, a Greek-myth theme and a stated 50,000x cap. Both reach up to 117,649 ways. Features and paytables differ. See our Bonanza Megaways page for the original.
Is Medusa Megaways fair?
Yes, at UK-licensed casinos the game must use a tested random number generator and pay back in line with its published RTP over the long run. The Gambling Commission requires independent testing before games are offered in Great Britain. Fair doesn't mean favourable: the 3.72% house edge applies to every spin, and losses are likely over time. How slot machines are tested explains the checks.
