How to play Monsters Unchained mobile slot

Red Tiger strengthens its collection of slots online with the Monsters Unchained slot machine, where you’ll unleash special Expanding Reels, Wilds and Multipliers for wins up to 19,281x your bet.

The Monsters Unchained mobile slot is a 5×3 reel, 243 ways to win game with a high variance and 19,281x your bet max win. We would have liked the 95.69% RTP to be above 96%, but that’s ok cause you’ll find frequent wins and lots of action thanks to a few key slot features.

Medusa, Minotaur and Cerberus join you as you spin across the five reels set in the deep depths where only mythological monsters should be kept.

These aren’t just there for show, as each one can come in handy every 10th spin and during the free spins to help reward you with some exciting wins.

Unleash the Monsters every 10th Spin

The base game in this Monsters Unchained online slot isn’t your typical spins. Yes, you bet between 0.10 and 4 a spin and watch the five reels spin like many slot games.

However, every 10th spin could see the 5×3 reels Expand up to 6×6 with 15,625 ways to win, up to 7 Wilds appear and up to x7 Multipliers roat onto the screen.

How? By finding coloured chain Breark symbols on spins one to nine. Do this, and you’ll start to break the chains holding the Minotaur, Medusa and Cerberus back. The more chains you break, the more powerful the features.

Then on the 10th spin, the monsters who’ve had at least one chain broken will perform their special powers helping to create some decent wins every 10th spin. After that, you then continue the cycle again.

That is until you hit the free spins bonus round.

Monsters Unchained Free Spins Prove

A Monster Spins symbol on reels 1, 3 and 5 triggers 10 free spins. They are hard to trigger, but when you do, you’ll find the most exciting spins of the game thanks to the Monster features remaining in play every spin.

Finding the chain breaker hammer symbols still breaks the chains of the Monsters in the free spins. However, you don’t have to wait for 10 free spins for their features to trigger.

The very next spin after breaking a chain, the monster will unleash its power for that spin and the remaining 10 spins.

Breaking all three chains on a Monster adds 3 free spins to your total and gives you the best possible chance at getting closer to the maximum win.

You’ll need to budget your cash to hit the free spins, and there are no guarantees you’ll win big, but they certainly add a flutter of thrills to your spins when you do trigger them.

Bonus Features

Wilds: Wild only appear as part of the Medusa feature if unchained for the 10th spin.

Chained Monsters: There are three chained monsters. During 9 spins, coloured chain breaker symbols will break one chain on the corresponding monster's chains when found across the five reels. Break three chains to unleash the full monster's power. Every monster with a broken chain will unleash its special power on the 10th spin. After the 10th spin, it resets for the next 10 and so on. The more chains are broken, the more powerful the feature is.

  • Minotaur - Expands the reels on the 10th spin increasing the ways to win. 1 chain broken = 5x4 grid + 1024 ways to win, 2 chains = 5x5 + 3125 ways to win, 3 chains = 6x6 reels + 15625 ways to win.
  • Medusa - Adds wild to the reels. 1 chain = 2 or 3 wilds, 2 chains = 4 or 5 wilds, 3 chains = 6 or 7 wilds.
  • Cerberus - Adds a win multiplier to the reels. 1 chain - x2 or x3 multiplier, 2 chains = x4 or x5 multiplier, 3 chains = x6 or x7 multiplier.

Monster Spins: 3 Monstery Spins symbols on reels 1, 3 and 5 give you 10 free spins. During the free spins, when a chain is broken, the corresponding monster will perform its power on the remaining free spins. Break all three chains of a monster to add +3 free spins. Max 19 free spins available.


  • Win up to 19,281x your total bet
  • Unchained Monsters unleash powers every 10th spin
  • Free Spins with richer features
  • Expanding Reels, Wilds & Multipliers


  • RTP can be lower at some slot sites

Monsters Unchained Review Conclusion

The Monsters Unchained slot game has great graphics, animations and, more importantly, some rewarding features. Every 10th spin can reward you with a nice top-up to your account if you find those all-important chain breaker symbols.

However, it's in the free spins bonus, which you'll need to budget to catch where the true thrills lie.

The Monsters Unleash their powers and show you their true colours with the Wilds, Expanding Reels and Multipliers offering some big win potential.

The betting range might be small, between 0.10 and 4 per spin, but there's still enough here for everyone to enjoy.

With some great features, this good-looking slot is easy on the eye but not so easy on the wallet unless you manage to hit that free spins bonus early.

Take it for a spin at one of our best Red Tiger casinos online and see how generous these monsters can be once you unchain them.
