Where to Play Mutagenes
Mutagenes RTP and Wagering
Mutagenes uses a 6x4 grid with 4,096 ways to win. If you can land three, four, five, or six matching symbols on adjacent reels (starting from the leftmost reel), you’ll get a cash prize shown on the paytable.
When playing Mutagenes, you can stake between £0.10 and £50.00 per spin. The game has a theoretical Return to Player (RTP) of 96.30%, which is over the 96% average rate. The slot game is highly volatile with a generous max win of 12,000x your bet. But as the symbol values are low overall, the bonuses are crucial for increasing the size of your wins.
Mutagenes Symbols and Audio & Video Design
Mutagenes is set in “the void of space”, according to the game’s description, where scientists are creating a new generation of humanoids. The location is a futuristic lab filled with equipment and atmospheric background details, such as fans rotating slowly and water tanks housing test subjects.
It’s primarily a sci-fi game, but there are elements of horror throughout. Such as? Check out the severed green hand symbol with twitching fingers, the rotating eyeball floating in fluid, and the red head with stitches across the top (like Frankenstein’s monster). But it all has a cartoonish charm — there’s no real gore to worry about.
The electronic music has a light-hearted and funky style that matches the visuals, with some fun sci-fi sound effects to enjoy. In terms of symbols, Mutagenes has six high symbols and four low symbols. The Red Head symbol pays the highest prize on the paytable: 4x your bet. That’s tiny for the top symbol, especially in a highly volatile slot.
A Wild symbol can appear on reels 2 - 6, and substitute for other symbols except the Scatter. The Scatter can trigger the Free Spins feature.

Mutagenes Mobile Features
As Mutagenes was developed in HTML5, it looks amazing on mobile devices. The graphics are colourful, sharp, and slick, with the same fun animations as the desktop version. You can play it in portrait or landscape mode, whichever you prefer. The game adjusts its layout to suit your device’s orientation, so the controls are always positioned conveniently.
Mutagenes Bonus Features
Mutagenes includes the following bonus features: Cascade, Free Spins, Expanding Wilds, Infection, and Golden Bet.
Free Spins
Land 3, 4, 5, or 6 Scatter symbols to win 9, 11, or 13 free spins, respectively. A multiplier applies to every win during the Free Spins feature: it starts at x1 and increases by 1 with each win. It won’t reset until the feature ends. Unfortunately, you can’t retrigger the Free Spins round.
You can pay to play this feature instead of waiting for it to trigger normally. The number of spins awarded is selected randomly (between 7 and 12 free spins). The RTP increases to 96.70%, too.
Golden Bet
Increase your stake by 0.5x per bet for a higher chance of landing Expanding Wilds or triggering the Free Spins round.
Mutagenes Final Thoughts
Overall, I had a good time with Mutagenes. The game’s setting, symbols, graphics, and sound are fantastic. They combine to give Mutatenes irresistible charm, and it’s clear that Peter & Sons has invested a lot of creative thinking into the game.
Mutagenes features more than 4,000 ways to win, and the max payout is generous at 12,000x your bet. The RTP is above average at 96.30%, but the high volatility can make the bigger wins harder to come by. It’s just a shame that it uses such low-paying symbols, with the top symbol awarding up to 4x your bet only.
Mutagenes’ bonus features are integrated well, especially the Free Spins round with increasing multipliers. That creates the potential to build some decent prizes across consecutive wins, despite the tiny symbol values.
