Monsters Unchained Features

If you want to see any modifying mastery then you are going to need to unchain those monsters and release their hidden powers. Between the three of them, they offer multipliers, expanding reels and wild symbols as well. 

It all takes place on the 10th spin and you can see where you are in the cycle by looking to the top of the screen. Regular winning combos occur on spins 1 to 9 and there's also a chance that one of the coloured hammers can land to break the corresponding chain of the monster. 

When you reach the 10th spin, all of the broken chains create a modifier and they grow in intensity with the more chains you have broken. It's a little hard to explain but it doesn't take a lot of getting used to. 

Modifiers & bonus game

The Minotaur expands the reels to 5x4 if one of his chains is destroyed. This goes further to 5x5 with 2 chains destroyed and 6x5 with all three chains destroyed. As a result, the larger grid brings extra win lines into play with a maximum of 15,625 available as all three chains stretch that grid as far as it will possibly go. 

Medusa will add Wilds with 2 or 3 Wilds for her first chain, 4 or 5 for the second chain and 6 or 7 for the third chain. Cerberus provides multipliers and has as an x2 or x3 multiplier for 1 chain, x4 or x5 for 2 chains and x6 or x7 for 3 chains. 

Moving on to the bonus feature, we have a fairly standard free spins game with 10 free plays coming your way when you land 3 Monster Scatter symbols. The slight difference here is that breaking just 1 of the chains will unleash the modifier on the next spin and you don't have to wait until the end. Obviously, there are only 10 free spins and you wouldn't see any modifiers at all if the base game mechanic continued in the bonus feature! 

Breaking all 3 chains of any individual monster will bring 3 additional bonus spins so that means you could have 19 free spins if all goes well.

Monsters Unchained Review

These 3 monsters from Greek mythology have real chemistry and they seem to work perfectly in tandem during Monsters Unchained. Breaking them free to release their modifiers is exciting but remember you will need to wait 10 spins for it to happen each time. 

While you're waiting for this, you’ll play a regular base game that won't pay out too many wins thanks to the high volatility. Everything hinges on that all-important 10th spin.


It's a kind of dark and Dickensian image that wouldn't be out of place in a horror movie. And a lantern burns brightly in the background with some sort of ghoul gripping the top of the reels with its bony claws. The 3 monsters sit to the left of the reels with their meters glowing and growing with each hammer that lands. Plus you can just make out the monster's tail wrapped around the bottom of the reels as well. 

Many small details have been considered and that is always appreciated by true slot fans. There's great news for mobile gamers as you can access Monsters Unchained wherever you might have an internet connection, so feel free to scare yourself to death on the bus, train or anywhere else you may find yourself.

Game Play

The monster modifiers are what make this slot a success in our opinion and the only real benefit of making your way to the Free Spins game it's to see them trigger more frequently. The base game doesn't feel like a long arduous journey and there are so many nice touches to look out for while waiting for wins to land. It's an exciting adventure and Red Tiger has pulled out all the stops.

Win Potential

You can't argue with a max 19,000x win but you might push back against the high volatility as you watch your balance begin to melt. You need to budget carefully for this one and hope that the 10th spin produces the big win that eases your bankroll back in the right direction. The RTP is 95.69%.

Our Verdict

It's always nice when a slot developer clearly goes above and beyond to impress its fans and that's exactly what Red Tiger Gaming has done on this occasion. They've taken so many things into account to create an entertaining slot session and we're pretty sure everyone will find a lot to like about Monsters Unchained.
