Beast Below Features

Admittedly, we thought the star of the show in Beast Below was going to be a bearded fisherman or perhaps an angry tuna. Turns out neither of these guesses were right and, instead, it's all about the sirens and their enchanting voices that may or may not lead us to great riches.

Expanding Sirens

Let's meet the cast! There are two sirens to watch out for and they are unimaginatively named the yellow siren and the pink siren. Both are wild symbols and during the base game, you will only see the yellow version. Her expanding skills occur by landing and forming part of a winning combo. Multipliers are added up to 200x and if she can help create a win in the row above, then she will expand upwards. This will continue until she reaches the top of the screen.

The Siren’s Call Free Spins

For 3 scatter symbols, you will receive 10 free spins and you get a better chance of seeing not only the yellow siren but also the pink one as well. Pink sirens will stay in place, unlike their yellow counterparts, and they are removed one step at a time by nudging up a row with each free spin. The multiplier values are the same for the pink characters. You can grab additional free spins by landing further scatter symbols during this bonus.

Down Below Free Spins

4 scatter symbols will also trigger 10 free spins but this game has an expanding diver symbol. These are also wild multipliers and will expand to cover the whole reel and remain in place for a number of spins. Your divers have oxygen charges to show how long they have left in the game. 

Divers can also move to adjacent reels and bring further multipliers along with them. They have the same max 200x multiplier values as the sirens and free spins are, again, awarded for additional scatter symbols.

Beast Below Review

We have no idea why sirens get such a bad rap! The only intention they appear to have in this game is to bring you a bucket load of cash, where possible, and help you haul it to shore to spend as frivolously as you wish.


Athletically, we weren't entirely jazzed by the way the reels are set in the foreground of this watery cove with the remaining part of the scene stretching into the horizon. However, after a couple of minutes, we started to quite like it and appreciate that the design team has done a very good job on Beast Below. It also looks very good on mobile screens for both Apple and Android products with no loss of quality experienced by either side. 

There are several animated touches to enjoy including the little swaying fishing boat with what appears to be a Kraken sprawled out on the deck. The soundtrack is menacing and interspersed with sonar sounds that give the whole production a special kind of dark ambience.

Game Play

It is possible to hit the biggest wins at any point during the game according to Hacksaw Gaming. However, we imagine that the biggest payouts are only likely to arrive during the free spins features. You can wait it out and enjoy the occasional yellow siren during the base game or go directly there via the Bonus Buy if you are outside the UK.

Win Potential

10,000x is there for the taking but remember that the medium-high volatility will continue to increase throughout the various feature elements of this game—the free spins bonuses are rated as very high. The RTP will also change according to the area of the game you are playing with the overall figure averaging out at 96.29%.

Our Verdict

Beast Below got off to a bit of a slow start but once we started to appreciate the intricate design elements, the slightly monotonous base game was actually quite fun to watch. Undoubtedly, the majority of the excitement and big wins are reserved for the bonus games so try and make your way there ASAP if possible.
