Mutagenes (Peter & Sons) – Review & Demo Play

Mutagenes: Slot Overview

As an experienced player, I stepped into this lab-in-space setup from Peter & Sons. The grid is 6 reels by 4 rows with 4,096 ways, wins left to right on adjacent reels. Stakes run from 10p to £50. Volatility is high and the default RTP sits at 96.3%, though lower versions exist. The look leans cartoony rather than grisly, backed by a retro sci-fi soundtrack. It all frames a game built around cascades, multipliers, symbol transformations, and a punchy top prize of 12,000x bet.

Symbols and Payouts in Mutagenes

Mutagenes uses a simple set of ten regulars plus wilds and scatters. With the All Ways layout, you need 3 to 6 matching symbols on adjacent reels starting from the leftmost side. The card suits sit as lows and pay up to 0.5x for a six of a kind. Wilds land on reels 2 to 6 in all modes and substitute for everything except the scatter, which is the entry point to the free spins feature.

The mids are syringes, hands, eyes in bottles, and brains in jars, paying up to 0.9x for six. Two character symbols carry the top tier, with a bandaged skull and a dismembered head worth up to 3x and 4x the stake for a full line. Payouts in the paytable scale with your chosen bet, so it stays easy to track wins as cascades land and new combinations connect on the 4,096 ways grid.

Mutagenes Slot Bonus Features

After any win, Mutagenes triggers cascades that remove the winning symbols and drop fresh ones from above. Each consecutive cascade increases the total win multiplier by +1, starting from 1x. In the base game the counter resets when no new wins appear. On a 4,096 ways setup this can snowball when several lanes line up at once, and those incremental steps make even middling connections add up while you wait for the high symbols to fall.

Infection can strike at random in both modes, turning any chosen low or mid into a high-paying symbol. It keeps the screen live between spins and often primes the grid for better cascades. Mutation also triggers at random and selects at least two reels. A batch of high symbols is then placed on those reels before the rest of the positions reveal. When these two features overlap, the reels can flood with premiums and set up hefty ways.

Three to six scatters award 7, 9, 11, or 13 free spins. During the round, the win multiplier climbs by +1 per win and does not reset until the feature ends. Wilds appear on reels 2 to 6 and may expand to cover the reel, except the first. Free spins cannot be retriggered. You can toggle Golden Bet for +0.5x stake to raise the odds of expanding wilds and the bonus. The buy option costs 120x and gives 7–13 spins at 96.7% RTP.

How to Win at Mutagenes

With 6 reels, 4 rows, and 4,096 ways, wins land when three or more match on adjacent reels from the far left. I focus on building cascades that nudge the multiplier rather than chasing single-line hits. Infection and Mutation lift hit quality by pushing more highs onto the grid, so I give sessions time to roll. Golden Bet can help start features faster, but the stake rises, so I only toggle it when the balance allows.

Mutagenes Slot RTP & Volatility

Mutagenes runs on high volatility with a max win of 12,000x bet. The default RTP is 96.3%, though versions at 94%, 90.5%, and 86% are in the market, so check the info panel. Hit rate is quoted at 23.27%, which matches the on-off flow I felt across sessions. Bets span 10p to £50 per spin, with Golden Bet lifting the stake by half. If you buy the feature for 120x, the published RTP shifts to 96.7% during that purchase.

The Final Thoughts on Mutagenes

I liked the mix of cartoony visuals and a slightly eerie lab theme in Mutagenes. The soundtrack gives it a quirky pulse, and the animations keep the screen lively without clutter. The feature set is tidy rather than sprawling, which suits a 4,096 ways engine that leans on cascades and multipliers. When Infection or Mutation step in and expanding wilds line up, the board can heat up quickly, especially once the multiplier starts climbing in the bonus.

For me, the appeal lies in momentum. Base game chains can pay back a session without waiting ages for scatters, while the free spins’ persistent multiplier gives a fair shot at something meaty. The lack of retriggers keeps runs compact, which I prefer on a high rollercoaster like this. With the 12,000x ceiling and a sensible buy price, Mutagenes lands in that sweet spot between fun and threat that makes me return for another round.
