Mutant Trawlers by Yggdrasil Bang Bang Games

Mutant Trawlers slot is a visually fun game even if the theme is an environmental disaster. This is probably the slot Greta Thunberg is playing in her nightmares. It is developed by Bang Bang Games of Yggdrasil Gaming. The backdrop is a once-serene lake, now polluted by a neighbouring power plant. It draws inspiration from The Simpsons‘ Blimpy episode. The dark humour is in the same vein as NoLimit City’s Ugliest Catch. Let’s see what monster wins out mutant trawlers can haul in from the ooze.

How To Play Mutant Trawlers Slot Demo

As you play Mutant Trawlers your main goal is to land matching symbols on the reels. Pay lines start from the leftmost reel. There are 243 different ways to win and you need to match symbols on a pay line for a win.

Mutant Trawlers Base Game
  • Spin: Choose a betting stake and start spinning. Wins will come from matching symbols on pay lines. Each spin can also land Mutant Cash symbols and trawler boats.
  • Boats: If a boat stops above a reel containing a mutant fish symbol, then the cash value is collected, and the boat is upgraded to a Trawler. Then a re-spin will occur and the trawler can connect more fish symbols on any reels.
  • Meltdown: Try and land 3 nuclear bomb scatters for the Meltdown free spins round.

Winning Combinations & Payouts

Most slots follow the low-value card and thematic high-value symbols formula, and Mutant Trawlers does this as well. In total there are 8 common symbols: 4 low paying and 4 high paying.

Mutant Trawlers Paytable

Low: 4 card symbols (J, Q, K and A) are low value symbols . Payouts range from 0.2x – 0.8x.

High: Protective goggles, Ooze Barrels, Radiation detectors and Nuclear fuel cells are high value symbols. They pay out between 0.3x – 5x.

Special Symbols

Radiation wilds, nuclear bomb scatters and mutant fish are the game’s special symbols.

Radiation Wild Symbol

Radiation Sign Wild

Radiation symbols act as the wild symbol in the game. They can substitute for all common symbols forming winning combinations.

Nuclear bomb Scatter Symbol

Mushroom Cloud Scatter

Landing at least 3 scatter symbols in the base game, will trigger the bonus round. Depending on how many scatters land (3 – 5) you can win 12 – 20 free spins.

Mutant Fish Cash

Mutant Fish Cash

Like most fishing slots, fish symbols carry cash prizes. If a fishing boat lands on the same reel as fish, then their cash values are collected. Trawler boats can catch fish on all reels and apply a win multiplier.

Base Game Features

Mutant Trawlers incorporates base-game features for some additional wins without having to be in the bonus round.

  • Mutant Fish Cash: Fish symbols can appear randomly on any spin. When fish symbols land on the reels, and a fishing boat appears above the reel, the cash value on the fish symbol is collected.
  • Trawler Re-spins: This is triggered when a boat collects fish symbols and is upgraded to a mutant trawler. Initially, the trawler awards a re-spin and starts with a 2x multiplier. Each re-spin increases the multiplier by 1, and every new boat that turns into a trawler, gets the same multiplier. The re-spins continue until no new fish symbols land.

Mutant Trawlers Bonus Game

Meltdown Free Spins bonus round starts when you land at least 3 scatter symbols. Landing 3, 4 or 5 scatters awards 12, 15, or 20 free spins, respectively. If you land only 3 or 4 scatters, then you can gamble your spins for more spins. But the maximum starting amount is 20 spins.

Mutant Trawlers Bonus Round

The bonus round plays out similarly to bonus features in the base game. Yet the main differences are that you are guaranteed boats on every spin. Furthermore, when a trawler multiplier is upgraded, that multiplier will remain as is until the next upgrade, instead of resetting back to 2x, when re-spins are completed.

Free spins end, when all spins are used up or you manage to reach a max win of 3,069x.

☢️ What makes the Meltdown Free Spins special?

Mutant Trawlers does manage to stand out among other fishing-themed slots. This is mainly due to the mutant theme applied by Bang Bang Games. While max win potential is only 3,609x it is still a lot. In our view, anything over 1,000x is play worthy. A blend of humour and horror offer a fresh vibe to the fishing games genre.
So, if you are tired of the standard oceanic adventures, then Mutant Trawlers will offer a nice fun alternative.
