How We Review Slot Games

We test and rate all slot games across 5 criteria, assigning a score out of 10 for each and an overall score that is an average of the 5. To build an accurate assessment of each game we gather information from the supplier and play in real play or demo mode. Find out more.

Mutagenes by Peter and Sons invites you behind the scenes of a mad scientist’s laboratory – in space. Amidst the floating heads and pots of goo you might be able to land a 12,000x max win. With high volatility and a varying RTP you’ll need to watch your bankroll, but the minimum bet of £0.10 is pretty budget friendly. The expanding wilds feature gives you plenty of ways to increase your wins too.

Testing Notes: Here’s What Happened When We Played Mutagenes

IMPORTANT: To give you an accurate assessment of the games we review our writers play 200 spins. Whilst this is a useful tool to help us review games and to give an example of what might happen when you play, keep in mind that 200 spins is only a very small sample and cannot be used to accurately predict what might happen over another 200 spins. The outcome of all slots play is always random.

Mutagenes isn’t do anything particularly new here – cascading wins and progressive multipliers are a common combo, but it’s the presentation that makes this slot. The quirky science lab has a lot going on and there are a lot of weird things to look at if you ever get bored of the reels. Not that you will because I found the game moved at a good pace. The win rate was 22% – between 1 in 4 and 1 in 5 spins producing a win of some kind. The best base game payout came via combinations of wilds and pay symbols and a good multiplier – 5x was as high as I got.

The free spins round with an 11x multiplier

But the best moment was the free spins round that dropped early on.  That kicked out a 44.9x win. Your progressive multiplier is persistent here so it just keeps growing between spins and mine got up to 11x. You can see that in the screenshot.

What We Liked

  • Progressive multiplier grows with every cascade
  • Quirky science lab theme with great visual production
  • Persistent progressive multiplier in free spins round
  • Good win rate of 22% in testing

What We Didn't like

  • Low RTP at some slot sites
  • Quite simple features and gameplay

What Our Reviewer Says ...

"A typically quirky sci-fi slot from Peter and Sons"

Overall Score: 7.6

Theme & Design

Our Score 8

Ever wondered how Frankenstein might have worked out if he’d been created in space? No, well no matter, as Peter & Sons have let us know with Mutagenes. This game is set inside an intergalactic laboratory, filled with various jars and potions, most containing parts of aliens. It seems, based on the symbols on the reels, that the scientists are hard at work creating a humanoid out of all of these parts.

However, don’t let this put you off. This slot definitely errs on the cartoon side of creepy, as most Peter & Sons slots do. If you’re after an out and out horror slot then this won’t be it, but if you’re after a funny take on a mad scientist theme then you’ll enjoy this game.

RTP and Variance

Our Score 7

What is RTP?

RTP (Return to Player) refers to the amount a game will pay out in cash prizes expressed as a percentage of all the money wagered on that game. For example, a 96% RTP means a game will pay out £96 for every £100 wagered. This is an average number and will vary from one session to the next.  Read more here.

What is Variance?

Variance refers to how far a game will deviate from its RTP over time. High variance games deviate a lot and produce uneven win distributions and unexpected windfalls. Low variance games provide a more stable and even distribution of wins. Read more here.

Mutagenes has four different RTP rates: 96.3%, 94%, 90.5%, and 86%. If you’re playing with the default RTP of 96.3% then that’s all well and good, but it’s super important to check, as the other RTPs really don’t offer a great return.

The high volatility is also something that players with a smaller bankroll should look out for, but it’s not uncommon to see high volatility in a slot with a generous top prize.

Maximum Win

Our Score 8

What Is Maximum Win?

Maximum win refers to the maximum amount a player can win from one spin. It is expressed as a multiple of the stake. For example, where the maximum win is 100,000x, from a £1 stake, the maximum win would be £100,000.  

Mutagenes has a top payout of 12,000x the bet which is a prize worth shooting for! When playing with the highest RTP, it turns the slot into a pretty generous one. If you’re serious about winning big then an alternative option is Space Miners Dream Drop which has a similar theme but a non progressive max win of 50,000x your bet and the chance to play for a huge progressive jackpot too.

Symbols and Paytable

Our Score 7

The game is payed on 6 reels and 4 rows and offers 4,096 ways to win. Wins are achieved via a win ways mechanic, meaning you need to land 3 or more identical symbols on consecutive reels – regardless of the row they land on – starting from the leftmost reel.

Mutagenes Paytable
The paytable with 4x for 6 or more top paying premiums

There are 10 pay symbols in total. The 4 low value symbols are clubs, diamonds, spades, and hearts. Landing 6 of the same symbol awards 0.5x the bet. The 6 premium symbols are syringes, hands, eyes, brains, skulls, and dismembered heads (delightful). Landing 6 of these symbols pays between 0.8x and 4x the bet.

Features and Gameplay

Our Score 8

Mutagenes has all kinds of interesting features that help to make the gameplay out of this world. Here is how it works:

Wilds and Expanding Wilds

The wild symbol – represented by the letter ‘W’ – substitutes for any normal pay symbol, helping you to complete win ways. Sometimes wilds will expand at random to fill an entire reel. 

Cascades

Every time a win is formed the winning symbols are removed and the cascade feature starts. New symbols drop down into the empty spaces, giving you more chances to win. The cascade feature only stops when no new wins are made.

Progressive Multiplier Counter

The multiplier counter resets to 1x every spin and +1 is added for every cascade. The multiplier is applied to each win. 

Infections

The infection feature is a whole lot better than it sounds. When triggered, a low paying symbol is transformed into a higher paying one. 

Free Spins

If you land 3, 4, or 5 scatters you start the free spins round with 7, 9, or 11 spins respectively. During the round the multiplier (from the multiplier meter) is applied to all wins. It starts at 1x and increases by 1 for each win. It remains persistent throughout the feature. 

Ante Bet

The Ante Bet feature let’s you pay an extra half of your stake per bet (0.5x) for an increased chance of landing expanding wilds and scatters. 

The Final Verdict

Mutagenes is one of those slots that just looks brilliant. If you’re a fan of the humorous horror genre then you’ll appreciate the weird and wonderful symbols, alongside the unspeakable pots of goop in the background. The whole thing feels a bit mad, but in a good way. The cluster pays mechanic is always popular and combining that with cascading wins helps to net you some successes.

The max win of 12,000x your stake is pretty generous and together with the highest RTP is a great combination. The volatility does seem to be super high with this slot, so that’s something to watch out for. However, the multitude of excellent features more than makes up for it. The free spins round with its super generous multiplier meter is definitely where those big wins are bound to land.

Useful Tips When Playing Mutagenes

Remember, online slots are games of chance, there is NO strategy that can improve your odds of winning. However, reading our review and following these tips will help you get the most out of your time playing this slot game.

1. Be Patient And Set A Low Stake

With high variance games like this one it makes sense to play with low stakes. It can burn down your balance fast as you wait for those big moments.

2. Watch The Infections 

At the bottom left or the reels you can see when an infection takes place, upgrading a symbol to a higher value one across the reels.

3. Check The RTP Before You Play

Open the game rules page and check the RTP before you play for real. Some slot sites will run this game at under 90% which is to be avoided.

4. Play At Our Recommended Slot Sites

We have chosen the sites on this page because they all scored high in our reviews and they are licensed by the UK Gambling Commission. That makes them fair and safe places to play slots.
