What Our Reviewer Says ...

"A beguiling high variance slot stacked with expanding wild multipliers and a thrilling bonus round"

Overall Score: 8.2

Theme & Design

Our Score 9

Beast Below showcases Hacksaw Gaming’s creative skills. This is a great-looking slot with tons of atmosphere and a suitably creepy soundtrack. It’s set in a rocky cove at night, a lonely fishing boat bobbing on the waves, seemingly overrun by a Kraken-type monster. Beneath the surface the murky waters house our reel set, a few fish swim by, air bubbles rise and strands of seaweed float upwards. It feels eerie, like the end of a horror movie where the heroes have all met their fate. Or maybe it’s the beginning. Whatever, the big question is … just what is lurking out there beyond the reels?

In short, if you enjoyed the style of Hacksaw games like Rotten and Cursed Seas then you’ll enjoy this too.

RTP and Variance

Our Score 8

What is RTP?

RTP (Return to Player) refers to the amount a game will pay out in cash prizes expressed as a percentage of all the money wagered on that game. For example, a 96% RTP means a game will pay out £96 for every £100 wagered. This is an average number and will vary from one session to the next.  Read more here.

What is Variance?

Variance refers to how far a game will deviate from its RTP over time. High variance games deviate a lot and produce uneven win distributions and unexpected windfalls. Low variance games provide a more stable and even distribution of wins. Read more here.

Beast Below has four available RTP settings: 96.29%, 94.27%, 92.25%, 88.28%. It is up to your casino operator to choose which setting to run the game at. The top setting of 96.29% is good, just above average for the UK but you won’t always be playing at this level. We verified the RTP at five popular casinos to find out which setting they run the game at. This is what we found:

Our research shows that MrQ offers the best value for your wagering on Beast Below. If RTP is an important consideration for you then we recommend that you play there. 

Beast Below is also a high variance slot, which is no surprise from Hacksaw Gaming who have a long list of volatile games in their catalogue. So if you enjoy chasing down those big wins and don’t mind sitting through some frustrating spells whilst you do … this is one for you.

Maximum Win

Our Score 8

What Is Maximum Win?

Maximum win refers to the maximum amount a player can win from one spin. It is expressed as a multiple of the stake. For example, where the maximum win is 100,000x, from a £1 stake, the maximum win would be £100,000.  

The maximum win on Beast Below is 10,000x. Again, this is average for a Hacksaw Gaming high variance slot. There are a few with higher top payouts if you are looking for better potential. We recommend RIP City, Cursed Seas and Wanted Dead or a Wild which are all capped at 12,500x and worth a spin.

Symbols and Paytable

Our Score 8

Beast Below is a 14 payline slot with 5 reels and 4 rows. To trigger a win you will need to land 3 or more identical symbols across the reels from left to right, starting at the far left.

Symbol values in the game are not huge, but again, we are in Hacksaw Gaming territory here so you can be sure that there will be plenty of high value multipliers to help boost your wins when they do arrive.

Beast Below Paytable
The Beast Below Paytable

Low value symbols are the cards, 10 through to Ace. They are valued at from 0.1x for 3 10s up to 3x for 5 Aces. The premiums are the deep-sea fish – spikey and weird looking things. They are valued at from 0.5x for 3 spikey bloaters up to 10x for 5 of the deep sea fish with headlamps!

There is also an Anchor Wild in this game that will substitute in for all other symbols to form winlines. It also pays out a nice 20x for 5 on a line.

Features and Gameplay

Our Score 8

As always with Hacksaw Gaming slots, Beast Below is not overladen with features, but the ones it has are top quality. In this case, expanding wilds are key, and as always, they bring with them plenty of multiplier action.

Expanding Siren Wilds

First up are the Siren Wilds. Sirens can land at any time. When they do, if by expanding upwards they would form part of a winning combination, then they expand from their position to the top of the row. These Sirens also come with multipliers of 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x, 15x, 20x, 25x, 50x, 100x or 200x.

More than one Expanding Siren Wild can appear on the reels at once, and if they both form part of a winline, their multipliers are added before being applied to the win.

Two Free Spins Rounds

There are also two free spins rounds in Beast Below. Look out for the FS Scatter Beast Below game logo which is required to unlock these.

Siren’s Call Bonus Round

Three scatters opens up the Siren’s Call Bonus Round with 10 free spins. Now, there is more chance of landing the original Expanding Siren Wilds, and a second Pink Siren comes into play. These also expand AND they remain on their reel, nudging upwards one row with each subsequent spin until they disappear off the top of the reels.

Pink Sirens also have multiplier values of 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x, 15x, 20x, 25x, 50x, 100x or 200x.

Siren’s Call spins can be extended by landing 2 scatters to get 2 more spins or 3 scatters to get 4 more spins.

Down Below Bonus Round

Four scatters triggers the Down Below Bonus Round with a Diver symbol which is another clever variation on the expanding wild. This one expands to full reel height and comes with 3 Oxygen Charges. At the start of each spin the Diver will move one reel to right or left, consuming one Oxygen Charge as he does and updating his multiplier value too.

Diver multiplier values are 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x, 15x, 20x, 25x, 50x, 100x or 200x.

And once their Oxygen Charge reaches zero, then they are removed from the reels.

You can have up to 3 Divers on the reels at once, their multiplier values added together when they combine across a winline.

This round can also be extended by landing 2 scatters to get 2 more spins or 3 scatters to get 4 more spins.

The Final Verdict

Beast Below is a truly beguiling slot from Hacksaw. Despite its ruthless behaviour during testing, with long runs of little return, it never got boring. Instead, it continued to intrigue and lure us in, just like the Sirens. Questions linger around what exactly that little boat is doing bobbing up and down on the waves, and what does lurk down there beneath? The genius part is, you can only truly find out by unlocking that final bonus round. It’s like a role play adventure game that you just have to complete. And when you do unlock that Down Below bonus, you see the Deep Sea Diver dropping to the ocean floor to help you gather coins whilst the looming Kraken monster looks over, waiting to strike, it’s like the narrative finally makes sense. It’s all about great treasures guarded by a classic monster, of course.

Storyline aside, the features here are fun too. We’ve seen similar before from Hacksaw. The expanding wild multipliers are a bit like the Cursed Chests that expand upwards with multipliers in Cursed Seas. But the highlight, and most original part of this game, is the Diver Wild whose Oxygen supply keeps him on the reels for 3 spins. The jeopardy here is intense particularly when they carry high value multipliers as you’ll want to keep the Diver going as long as possible. And of course, it’s all beautifully woven into that narrative.

To conclude then, this is another very enjoyable slot with an intriguing storyline from a developer at the top of their game.
