Beast Below

If you’ve been spinning reels as long as I have, you know Hacksaw Gaming’s reputation: high-volatility math, tight grids, and bonus rounds that’ll test your patience and your bankroll. Beast Below, which hit the scene on June 22, 2023, is pure Hacksaw—lean, mean, and brimming with tension.

This slot pops right out of the crowd. You’re playing on a 5x4 grid with just 14 paylines, and it’s got that signature high-volatility punch. There’s a 10,000x max win up for grabs, and the top Beast Below RTP clocks in at 96.29%—but don’t forget, there are lower versions floating around too.

The theme? Think deep-sea adventure. You’re that lone diver plunging into shadowy waters, with mythical sirens and all sorts of sea monsters lurking below. This is a slot that really pulls you under—immersive, moody, and designed for those of us who chase risk for the thrill of it.

If you’re familiar with Hacksaw’s Cursed Seas, there’s a bit of a spiritual connection here, but Beast Below is its own beast entirely. The 14-payline setup is the tightest I’ve seen from them, which means variance is razor-sharp—when you hit, you really feel it.

Here’s where it gets exciting: two separate free spins modes, expanding siren wilds with multipliers up to 200x, and a diver reel that can completely change the flow of a bonus.

Quick Verdict And Key Numbers

Provider Reputation And Early Take

Hacksaw Gaming has always pushed high-volatility, tight-grid slots, and they love giving us bonus buys for instant action. Beast Below fits right into that mold. The 14-payline grid is even tighter than usual—so any win feels concentrated, not scattered across a zillion lines.

If you’re comfortable with variance and know how to manage your bankroll, this one’s got serious potential. Dual bonuses keep things fresh, and the 10,000x top prize is worth chasing. I’d say the features here are well-balanced for the risk, but you’ve got to respect how often you’ll blank on spins.

Third-Party Assessment Snapshot

SlotArk, which I tend to trust for honest reviews, rated Beast Below a 7.9 out of 10 and put it in their “Recommended” tier. They point out that 25% hit frequency as a weak spot (and yeah, it’s noticeable) and warn about the big drop in RTP between the highest and lowest settings. Those are real, data-driven observations—not just regurgitated marketing.

As of now, I haven’t seen any big-win trackers or community polls for this slot. It’s still early days.

Industry Standards Comparison

This slot’s max win is way above the average, and the RTP (if you get the best version) is competitive. But with just 14 lines and a lower hit rate, it’s definitely a slot for those of us who like our games spicy and unpredictable.

Core Specs And How The Game Pays

RTP Variants, Volatility, And Bet Range

There are four possible RTP settings for Beast Below—so the difference between the best and worst is almost 8%. That’s not just a number; it’s a real chunk of your bankroll over time. Always pop open the paytable and check the RTP at your casino before you play. These stats shape everything about your session.

Bets start at $0.10 and go up to $100 per spin. That’s pretty standard for recent Hacksaw releases. Go max bet and you’re looking at a theoretical $1,000,000 top prize—if you can tame the beast.

Here’s the full breakdown if you’re detail-obsessed like me:

5x4 Layout With 14 Fixed Paylines

Let’s talk setup. Beast Below’s 5x4 grid with 14 fixed paylines is as compressed as it gets for Hacksaw. For comparison, Eye of the Panda gives you 27 lines, and Dorks of the Deep goes all the way to 46. With just 14, you don’t get as many little nibbles—but when a premium cluster lands, the reels come alive and you feel every cent.

Payouts always go left to right, starting from reel 1. Since all paylines are fixed, you’re always playing all 14—no matter what bet you choose.

Paytable, Symbols, And Winning Rules

Alright, let’s break down the symbols and what you’ll see spinning on Beast Below. If you’ve played Hacksaw’s high-volatility slots before, you’ll recognize this tiered structure right away.

High-value symbols:

• Pink siren symbol (this one’s an expanding wild, and when it shows up, things get interesting)

• Diver symbol

• Sea creature or beast icons—think tentacles, jaws, all that deep-sea menace

Low-value symbols:

• Card ranks (A, K, Q, J, 10, 9), but dressed up in watery, aquatic style—way more fun than plain old cards

Special symbols:

• Wild: The anchor wild stands in for any regular pay symbol and shows up on reels 2 through 5.

• Scatter: FS scatter triggers the bonus rounds, and how many you land decides which bonus you get.

• Siren wild: This is the expanding wild with attached multipliers—seriously, don’t sleep on this one.

Line up matching symbols on at least three reels, starting from the first one on the left, and you’ve got a win. Only the highest win per payline pays out each spin—no stacking up multiple wins on the same line here.

Theme, Reel Flow, And Base Game Mechanics

Underwater Horror Setting And Visual Identity

This isn’t your sun-soaked beach slot. Beast Below drags you into the abyss—think deep ocean, shadows, and those eerie, shifting silhouettes behind the reels. The vibe is more maritime horror than tropical getaway, and I love it for that.

Animations pop, especially when you hit those siren or diver symbols. The sound design? It keeps the tension simmering, but never gets annoying, even if you’re grinding out a long session. Hacksaw’s polish shines through—if you’ve played Stack’Em or Dork Unit, you’ll know what to expect here.

Expanding Sirens And Base Game Multipliers

Let’s talk about what makes the base game tick. The expanding siren wild is the real star here. When you land a pink siren wild, it takes over the whole reel—boom, full vertical wild with a multiplier attached.

Here’s where it gets exciting: every siren wild comes with its own multiplier, and these can hit up to 200x your bet. That’s not just window dressing; it’s the key to those heart-pounding hits.

• Expanding siren wilds stretch out to cover the entire reel whenever they land.

• Each siren wild brings its own multiplier, which applies to any win it helps create. If you’re chasing big wins, this is your ticket.

• If you land more than one siren wild in a spin, their multipliers combine—so you’re not just adding, you’re multiplying your shot at a monster payout.

• This combo effect is how you chase down those 10,000x max wins. It’s rare, but when it happens? The reels come alive.

Honestly, with only 14 paylines, you’d expect wins to be modest, but those stacked multipliers can turn a single spin into something epic. That’s the beauty of high-volatility slots—you never know when the big one’s coming.

How To Play Beast Below

Jumping in is easy, but a few tips can help you get the most out of your session. Here’s what you’ll do:

1. Pick your bet—use the +/- buttons. You can go as low as $0.10 or crank it up to $100 if you’re feeling brave.

2. Hit spin or set up autoplay. You can set stop conditions if you want to keep your budget in check.

3. Keep an eye out for siren wilds—they’re the main event in the base game, and seeing them expand is always a thrill.

4. Chase those scatters. Three FS scatters get you into Siren’s Call free spins. Four scatters? That unlocks the Down Below bonus, which is where the real fireworks happen.

5. Bonus buy is there if your casino offers it. Sometimes, you just want to skip the wait and jump into the action.

You can set up autoplay with your preferred limits. The base game has a steady rhythm, but those siren wilds and their animations keep things lively, especially when you’re building toward a bonus trigger.

Bonus Features And Buy Options Explained

The Siren's Call Free Spins Mode

Siren’s Call is the bonus you’ll see most often, triggered by landing 3 FS scatters at once. This isn’t just a standard free spins round—the way multipliers work here is what really sets it apart.

• Siren wilds don’t reset their multipliers between spins. Instead, every new siren wild adds its multiplier to whatever’s already on that reel.

• Land another siren wild in the same spot? The multiplier keeps stacking. You can feel the tension build with every spin.

• The expanding wilds from the base game are still active, so you get those dramatic full-reel wilds as well.

Early spins might feel a bit slow, but if you start stacking multipliers, the last few spins can really take off. There’s nothing like watching those multipliers climb and realizing you’re in for a wild ride.

Down Below Bonus Game And Diver Reel

Now, Down Below is the premium bonus—four FS scatters gets you in. It’s not easy to trigger, but if you’re hunting for the biggest wins, this is where you want to be. The diver reel adds a whole new layer of gameplay you won’t find in most slots.

• When you enter this bonus, a special diver reel appears alongside the main grid. The diver symbol moves around, and you’ll be rooting for it every spin.

• Every time the diver collects an oxygen charge, your bonus round gets extended. It’s a race against time, and every extra spin feels like a lifeline.

• As the diver drops deeper, you’ll see expanding diver wilds and moving wilds spread across the reels. This is where things can get a little wild—pun intended.

• If you’re lucky, you’ll land multiple diver wilds at once, stacking up for some seriously satisfying wins.

Bonus Buy, Bonushunt FeatureSpins, And Siren FeatureSpins

If you’re like me and sometimes just want to skip straight to the good stuff, bonus buy is a lifesaver—when your casino allows it. Beast Below doesn’t just offer one buy option; you get a whole menu:

• Buy Siren’s Call free spins directly.

• Buy Down Below and try your luck at the premium bonus.

• BonusHunt FeatureSpins: This mode tweaks the math to make bonus triggers more likely during your paid spins. Hacksaw’s BonusHunt system is a favorite for those who like to chase features.

• Siren FeatureSpins: Want more siren wilds? This option boosts their frequency during your purchased spins, making for some wild base game moments.

Heads up—bonus buy isn’t always available, depending on where you play. Some places restrict it. Also, the RTP can shift depending on which mode you’re in, so always check the info screen before you buy in. I’ve seen players surprised by this, so it’s worth a quick look.

Who It Suits, Similar Slots, And Final Trade-Offs

Best Fit By Bankroll And Risk Tolerance

Let’s be real—Beast Below isn’t for everyone. This is a slot for players who love the thrill of the chase and don’t mind waiting out dry spells for those big, adrenaline-pumping hits.

Best suited for:

• Anyone comfortable with long stretches between big wins. If you’re chasing the bonus, patience is a must.

• Players with a bankroll that can handle at least 200 spins without sweating it. You need some staying power here.

• Slot fans who live for complex bonus rounds rather than little base game nibbles. The features are rich, and when they hit, it’s worth the wait.

• High-volatility lovers who’ve already enjoyed Hacksaw’s other big hitters like Stick’Em or Stack’Em.

Probably not for:

• Folks who want lots of small wins to keep the session going. This game can be a grind.

• Players on a tight budget or who only want a quick session. The variance can eat you up if you’re not prepared.

• Anyone who doesn’t double-check the RTP at their casino before playing. Don’t get caught off guard!

If you’re going to dive into a high-volatility beast like this, I’d say plan for at least 150 to 250 spins at your chosen bet size. Anything less, and you’re just rolling the dice on variance. Stick it out, and you’ll get a real feel for what Beast Below can deliver.
