Medusa Megaways slot: what you need to know

Medusa Megaways comes from NextGen and takes its theme from the Greek myth of Medusa, the Gorgon whose gaze turned people to stone. It uses the Megaways reel system, first seen in Big Time Gaming’s Bonanza in December 2016, where each reel shows a random number of symbols on every spin.

The game combines three familiar ideas: Megaways reels, cascading wins and a free spins multiplier that grows. It sits in the high-volatility band and has a 50,000x cap, so it’s built for big swings rather than steady returns.

How the Medusa Megaways reels create 117,649 ways

On a Megaways slot, each reel shows a random number of symbols on every spin. Wins normally count on adjacent reels from the left, and the total number of ways is all the reel heights multiplied together. The maximum 117,649 is what you get when all 6 reels show 7 symbols: 7 × 7 × 7 × 7 × 7 × 7.

Ways to win at different reel heights (arithmetic examples)
Symbols on each of the 6 reelsCalculationWays to win
2 on every reel2 to the power 664
4 on every reel4 to the power 64,096
2, 3, 5, 7, 4, 62 × 3 × 5 × 7 × 4 × 65,040
7 on every reel7 to the power 6117,649

Medusa Megaways also has a top reel above the main six. In Bonanza, the original Megaways game, a horizontal reel above reels two to five adds one extra symbol to each of those reels. The paytable for Medusa Megaways shows exactly which reels its top reel covers.

More ways don’t change the RTP. They change how often small combinations appear and how the return is spread, which is part of what sets the game’s volatility.

How the features work in Medusa Megaways

Cascading wins

After a win, the winning symbols are cleared away and new symbols fall into the spaces. If the new arrangement makes another win, that pays too and the process repeats. One paid spin can therefore produce a chain of wins until no new combination forms.

Medusa wild

Medusa is the wild. She substitutes for every symbol except the scatter, which helps connect symbols across the six reels and can keep a cascade chain going.

Free spins with a rising multiplier

Three or more scatters trigger free spins. During the round, a win multiplier increases with each cascade. That means a long chain of cascades in the bonus gets progressively more valuable, and most of the game’s big outcomes depend on this happening.

  1. Spin the reels and note how many symbols each reel shows; that sets the number of ways.
  2. Matching symbols on adjacent reels from the left form a win, with Medusa filling gaps as a wild.
  3. Winning symbols cascade away and new ones drop in, possibly creating another win.
  4. When no further win forms, the spin ends and the total is paid.
  5. If three or more scatters landed, the free spins round begins, where every cascade raises the win multiplier.

Is the Medusa Megaways reel layout random?

Yes. Reel heights, symbols and cascades are all decided by the game’s random number generator (RNG). In Great Britain, the Gambling Commission’s RTS 7 standard on random outcomes (opens in a new tab) sets the requirements, and games are checked by approved test houses (opens in a new tab) before release.

There is no pattern to spot and no better time to play. A big win doesn’t make another one less likely, and a long run of losses doesn’t make the bonus due. Our page on whether casino apps rig games covers this in more detail.

Medusa Megaways RTP and cost in pounds

With an RTP of 96.28%, the house edge is 3.72%. That is the average cost of play: whatever you stake, multiply by 3.72%. High volatility means your actual results will often be well away from the average, mostly below it.

The table assumes an illustrative 550 spins an hour. Cascade chains make some spins last longer, and UK rules set a 2.5-second minimum per spin, so the absolute ceiling is 1,440 an hour.

Average cost of 550 spins at 96.28% RTP
StakeTotal stakedAverage loss (3.72%)
10p£55£2.05
50p£275£10.23
£1£550£20.46
£2 (18–24 maximum)£1,100£40.92

A £20 budget on Medusa Megaways

£20 gives you 200 spins at 10p, 40 at 50p or 20 at £1. The average loss on staking that £20 once is about 74p at every stake. The difference is how long your budget lasts: on a high-volatility game with a bonus-driven return, 200 spins give a much better chance of seeing free spins than 20.

Set a deposit limit before you start, and stop when the budget is spent rather than topping up.

Medusa Megaways max win

Wins are capped at 50,000x your stake. In pounds: £5,000 at 10p, £25,000 at 50p, £50,000 at £1, £100,000 at £2 and £250,000 at £5.

The cap is the game’s design limit. The rising multiplier in free spins is how the game can approach it, but outcomes anywhere near the cap are very rare.

Medusa Megaways on iPhone and Android

If your casino app lists Medusa Megaways, it opens inside the app with nothing extra to install. Your account and balance are shared with the casino’s mobile site.

Megaways games are among the busiest slots to view on a phone. With up to 7 symbols stacked on each of 6 reels plus a top reel, individual symbols are smaller than on a standard 5x3 game, and cascades move quickly across the whole grid. A larger screen helps. Our guides to Megaways slots on mobile and portrait vs landscape mode explain what to expect.

  • Install casino apps only from the official App Store or Google Play listing; see iPhone and Android phones.
  • A dropped connection doesn’t change the outcome, which is settled on the casino’s server.
  • Animated cascades use more battery than simple games; our page on battery life has general tips.

Frequently asked questions

What is the RTP of Medusa Megaways?

Medusa Megaways has a published RTP of 96.28%, so the house edge is 3.72%. Over a very long run that’s an average loss of £3.72 per £100 staked, although short sessions can be far above or below. A casino may offer a different version, so check the game’s info screen. Our guide to finding the RTP in an app shows how.

How many ways to win does Medusa Megaways have?

Up to 117,649. The number changes from spin to spin because each of the 6 reels shows a random number of symbols. When all six show 7 symbols, the ways reach 7 × 7 × 7 × 7 × 7 × 7 = 117,649. On a spin with 2 symbols on every reel, there are only 64. Our Megaways glossary entry explains the system.

What is the max win on Medusa Megaways?

The maximum win is 50,000 times your stake. That’s £5,000 at 10p, £50,000 at £1 and £250,000 at the £5 UK maximum for players aged 25 and over. Results near that level are very rare on a high-volatility game. Our multiplier glossary entry explains how stake multiples are worked out.

How do free spins work on Medusa Megaways?

Three or more scatters trigger free spins. During the round, winning symbols still cascade away, and the win multiplier increases with each cascade, so long chains are worth more as they go on. Medusa, the wild, substitutes for everything except the scatter. Our guide to free spins in casino apps explains how bonus-round spins differ from offer spins.

Who makes Medusa Megaways?

Medusa Megaways is made by NextGen. It uses the Megaways reel system that Big Time Gaming introduced with Bonanza in December 2016, combined with cascading wins and a rising free spins multiplier. For other studios’ games on our site, browse our list of slot studios.

Can I play Medusa Megaways on my phone?

Yes, if your casino carries it, Medusa Megaways runs inside the casino app or mobile browser with no separate download. Megaways grids show many small symbols, so a larger screen makes cascades easier to follow. Look for it in the app’s game lobby. Our page on which casino apps have Megaways slots can help.

Is Medusa Megaways high volatility?

Yes, it’s rated high volatility. Much of its return comes from the free spins, where the multiplier grows with each cascade, so many base-game spins return little or nothing. Playing at a lower stake gives your budget more spins. Our explainer on volatility in slot apps covers how to use the rating.

Can I buy free spins on Medusa Megaways in the UK?

No. Since a Gambling Commission warning in January 2020, feature buy-ins are not offered to British players, so free spins are triggered only by landing three or more scatters. Autoplay and turbo spins are also unavailable on UK slots. Our page on UK game design rules explains what else is different.
