Atomic Mushrooms - Review, Demo Play, Payout, Free Spins & Bonuses

Introduction

Fungi apparently have more in common with the animal kingdom that they do with plants. They even have their own classification, with fungi said to outnumber plants by six to one according to some experts. They are the root cause of many infections, yet at the same time they offer treatment options too - antibiotics would never have been created without help from the fungal kingdom.

You might not necessarily think of mushrooms when considering playing fantasy themed slots. But a couple of slots developers have done, so we’ve already experienced the fun gameplay offered by the mystical Magic Mushrooms online slot. Now Thunderspin have decided to tackle the subject, and as you might expect from this innovative developer, they’ve presented us with an outrageous game premise. So suspend disbelief and prepare to enter a post-apocalyptic world in which mushrooms are the sentient beings.

Theme, Graphics & Soundtrack

Everyone knows an atomic bomb generates a mushroom cloud. But Thunderspin have run with the mushroom theme and imagined a strange dystopian future in which radioactive mushrooms are the protagonists. There’s a mushroom cloud too, during the bonus Pick game, making this an extraordinarily light-hearted vision of a post-nuclear landscape.

The theme certainly won’t be to everyone’s taste, but if you’re not offended you’ll discover an excellent game with some exciting features. The graphics and animations are great fun, and there’s a suitably weird and funky rock soundtrack to accompany gameplay.

Atomic Mushrooms RTP & Volatility

The RTP of 95.6% is slightly lower than average, but not by much. Atomic Mushrooms is a low-volatility game, so it should deliver plenty of winning combinations. Whether or not they’ll increase your game balance is a matter of luck! But you can help to create your own luck by exploring this, and other Thunderspin free slots, right here before risking your own cash.

Atomic Mushrooms Bonus Features & Free Spins

There’s a Wild symbol in Atomic Mushrooms, represented by a scrawny brown mushroom with a rumpled red hat. Although it can’t generate wins on its own, it can substitute for all other paytable symbols to help you create winning combinations.

The Wild also behaves like a Scatter symbol, so landing three or more generates the Free Spins bonus round. The number of Free Spins you’ll receive depends on how many Wilds appear on the reels to generate the feature. All wins during the bonus round are subject to a 2x Multiplier initially.

3 Wilds = 15 Free Spins
4 Wilds = 20 Free Spins
5 Wilds = 25 Free Spins

Throughout the Free Spins bonus round an extra symbol is added to the reels. This is the blue Atomic symbol, which awards two additional free spins whenever it appears. And with every four Atomic symbols that land, an extra piece is added to the bomb which sits alongside the reels. Every piece added causes the bonus Multiplier to increase by x1, helping to generate even bigger payouts.

There’s also a Bonus symbol in the shape of a double-headed mushroom. This icon only appears on the central reel, but every appearance awards the bonus Pick game. You’ll be shown three mushrooms and asked to make your selection. Uncover the golden atomic mushroom cloud and you’ll win an instant cash payout.

Overall Review

The theme for Atomic Mushrooms is really out there, but Thunderspin have managed to pull it off thanks to some fun graphics and great bonus features. The mushroom characters are weird but somehow cute at the same time, and the animations really add to the fun.

But it’s the increasing multipliers in the Free Spins bonus round that really steal the show in this game. It’s fun helping to assemble the bomb as the wins stack up, and it can generate some big cash payouts. But we advise a period of demo play to familiarise yourself with the game to give yourself the best winning chances.
