🐙 Hey everyone, Lily Adams here - your favorite Casino Mom!

👻 I'm so excited to share my thoughts on the new underwater slot game Beast Below. This thrilling new release from Hacksaw Gaming takes us deep into murky waters as we search for sunken treasures.

🌊 But beware - there are spooky sea creatures lurking in the abyss.

Let's dive in and see what awaits in Beast Below!

Raiting by

Graphics and Theme: 4/5

The graphics and art direction in Beast Below are simply sublime. As soon as I entered the game, I was mesmerized by the visuals. You really feel like you've dived beneath the waves into a dangerous but alluring underwater realm.

The color palette perfectly captures the gloominess of the seafloor, with shadows and silhouettes adding to the mystery. The background animations like the bobbing fishing boat establish a sense of motion and vibrancy. And the sea creatures look incredible, especially with their neon glows piercing the darkness.

It's clear this slot was crafted with love and attention to the smallest details. From the seaweed accents to the fish calmly swimming by, Beast Below feels like an entire living world. I was totally captivated exploring every inch of the screen.

The mythological theme centered around sirens is brilliantly executed too. It's a fresh take compared to standard underwater/pirate tropes. And the siren symbols tie nicely into the innovative gameplay features.

Sound Effects & Music: 3/5

The sound design matches the mysterious mood perfectly. The ambient ocean noises like bubbles and drips make you feel immersed underwater. And the foreboding music establishes tension, like something dangerous lurking unseen.

I loved little touches like the sonar ping sound effect when spinning reels. And win celebrations have visceral audio cues, like deep sea roars and rumbles. The sirens even have haunting sing-song voices!

At times the minimalist soundtrack and repetitive ocean loop gets slightly monotonous. Some added melodies could spice things up. But overall, the audio enhances the atmosphere and gameplay nicely.

Gameplay: 4/5

Despite a classic 5x4 reel format, Beast Below feels very innovative gameplay-wise. The two bonus features with expanding symbols and moving wilds add serious excitement. And the bonus buy option lets you jump right into the action.

The base game provides a good balance of volatility. Payouts from normal spins are frequent enough to keep your bankroll healthy. But the big wins come from triggering those bonuses and stacked wilds.

Having two bonus features gives the gameplay nice variety too. The Siren bonus focuses on expanding wilds while the Diver feature has moving wild reels. So you get the best of both worlds!

The only downside is that bonus triggers can sometimes be scarce during long dry spells. But the gameplay makes up for it when those features finally hit. Overall, extremely enjoyable and addictive.

Rewards: 4/5

Beast Below definitely delivers on the reward front, with a max payout of 10,000x your bet. Even in the base game, the stacked wilds can result in some epic wins. But it's really the two bonus features where the big bucks come in.

The multipliers in the Siren and Diver bonuses, up to 200x, lead to insane payouts when you get multiple stacked on a payline. I hit over 300x my bet a few times just from those wild multipliers combining.

The free spins also add frequent payouts, especially when you retrigger more spins. After one particularly lucky Diver bonus, I walked away with over 600x my bet! That kind of profit makes all those smaller payouts worthwhile.

While high volatility means the jackpot hits less often, the sheer size of the potential payouts in Beast Below keeps your hopes up. This slot can definitely make you rich when lady luck is on your side!

Originality: 3/5

From a theming perspective, the siren mythology is a fresh approach for an underwater slot. Gameplay-wise, having two separate bonuses with expanding wilds and moving wild reels feels new and innovative too.

However, when you look at Hacksaw's full catalog of slots, certain elements feel a tad recycled. For instance, the multiplying wilds appear in various other titles like Dragons Fire, Legion of Gold, and Desert Treasures. Fans might find the features familiar.

That said, Beast Below still feels distinctive thanks to the immersive graphics and haunting mythological characters. While not Hacksaw's most groundbreaking or unique slot, it still retains the studio's signature boldness and creativity. Overall, a solid effort on originality but not their most innovative.

Overall: 3.6/5

When you add up all the elements, Beast Below is an absolute triumph that I happily give 4 stars. The graphic quality sets a new bar for underwater slots, and the siren mythology provides an intriguing theme. Gameplay stays exciting thanks to the bonuses and big payout potential keeps you hooked for more.

Sure, certain aspects like the sounds and some bonus features are a tad recycled. But overall, Beast Below is a showcase of Hacksaw's top-notch talent for creating atmospheric, gorgeous, and rewarding slots. Definitely an instant favorite that I'll be playing regularly for that massive 10,000x jackpot!

The mysterious theme centered around sirens draws you into an eerie underwater world. Gameplay stays exciting with two bonus features: The Siren's Call and Down Below.

My Thoughts Overall

Beast Below impressed me across the board. The second I loaded it up, I was stunned by the artwork and level of polish. Hacksaw clearly crafted this with care and artistic passion.

The graphics are mind-blowingly gorgeous, especially for an underwater slot. From shimmering lights to sinister shadows, everything captures the mystery of the deep sea. It's a joy to explore every detailed inch while spinning.

And the innovative bonuses add real excitement, especially when those wild multipliers start stacking up! The free spins always deliver a thrill since huge payouts are possible with lucky wild combinations.

My only gripe is the generic soundtrack and certain recycled gameplay elements. But even with its minor flaws, Beast Below is still an absolute joy to play. When I want to dive for big wins and get lost in a beautiful aquatic paradise, this is my go-to!


These features, especially when combined, provide the tools for unlocking this slot’s maximum potential payout of 10000x your total bet.

Extra Features

two_sirens symbol

Expanding Sirens

The yellow siren acts as an expanding wild on every spin. When it participates in a win, the siren will cover its entire reel and display a random multiplier value that is then applied to the payout.

Having two or more yellow sirens expand on a single winning combo causes their multiplier values to be added together, leading to some huge potential wins.

The Sirens' Call

Landing three octopus scatter symbols starts The Siren's Call bonus round with 10 free spins. Here you have an increased chance of hitting those all-important siren symbols compared to the base game.

The pink siren can also now appear and will expand to cover its reel on the first free spin. Then on every subsequent spin, the pink siren shifts one row up until it disappears off the reels. Any wins made using the pink siren will benefit from a random multiplier of 2x to 200x.

Two more octopus scatters during this feature will award an additional 2 free spins, while three scatters give 4 more spins.

expand_4 symbol

Down Below

Finding four octopus scatters takes you to the Down Below free games feature. Again you'll receive 10 starting spins with extra spins possible.

The Down Below round introduces expanding blue diver wilds that can occupy an entire reel with multipliers from 2x to 200x. The diver symbol also moves one reel to the left or right at the beginning of each spin, decreasing its oxygen level. Once its oxygen runs out, the diver disappears. Having two or more divers expand on a payline applies their combined multiplier values to any wins.

As with The Siren's Call, two scatters give 2 more spins and three scatters award 4 additional spins.

Maximum Win Potential 10000x

In Beast Below slot, the maximum possible win is a stellar 10,000x your stake, providing scope for massive rewards with the right bet size and luck. Even at minimum bets, the top win can lead to a 5-figure cashout, taking the underwater adventure to another level!

However, chasing the max win requires tremendous luck across multiple variables like bet-size, symbol alignments, and feature activations. A more viable approach is capitalizing on expanded wilds and bonus game multipliers to accumulate solid short-term wins.

Ways to Win

The criteria to hit a winning combo in the primary game are the same during bonus rounds and free spins unless noted differently. Every bet qualifies for all potential win combinations unless indicated otherwise.

Victory comes when matching icons line up on any of the designated 14 possible lines across adjacent reels, moving from left to right, beginning with the far-left reel. Check out the paytable to see how many of each symbol you need to land a win.
