How To Play Beast Below Slot Free

Beast Below Base Game

If you want to play Beast Below demo game, then you will need to find a casino that offers this option. But in the UK it is not allowed, so you will need to review all the slot information first before placing a real money bet.

  1. Set Your Bet: Start by choosing your bet amount, ranging from £0.10 to £100 per spin.
  2. Spin the Reels: Once you’re ready, hit the spin button to start the game. There’s also an auto-spin option available.
  3. Special Features: Look out for Siren (evil mermaid) wild symbols that expand and carry win multipliers. Moreover, there are also scatter symbols that lead you to the bonus rounds.

Expanding Sirens symbols can expand upwards, filling the reels from where they land. You can find this feature too in Grab a Bite and Wild Whopper slots. Scatter symbols can trigger one of two free spins bonus rounds.

Winning Combinations & Payouts

In Beast Below, you have low and high-paying symbols in the base game. To trigger a payout, you need to align at least three identical symbols on any of the 14 fixed pay lines, starting from the left to right. The more symbols matched on a pay line, the greater your payout.

Beast Below Paytable
  • Low-Paying Symbols: Classic card symbols (10, J, Q, K, A). Payouts range from 0.1x – 3x.
  • High-Paying Symbols: Five types of deep sea fish are the higher-value symbols. Payouts range from 0.5x – 10x.

Special Symbols

In addition to common symbols, there are also 3 special symbols: siren wilds, diver wilds and scatters.

Siren Wild

Siren Wilds

There are two types of Sirens in the game, yellow and pink. Both can substitute for any common symbol. Yellow sirens appear in the base game and can expand, with multipliers from 2x – 200x. Pink Sirens appear during the Siren’s Call bonus round and are sticky with progressive multipliers, nudging up one row with each spin.

Diver Wild

Diver Wilds

Divers are special wild multipliers appearing only during the Down Below bonus game. Divers expand to cover entire reels and remain in place for several spins. Each Diver has a set number of oxygen charges that count down each spin. They can also move to another reel each spin.

Kraken Scatter Symbol

Free Spins Scatters

Scatters unlock the game’s bonus rounds. Landing three scatters will trigger the Siren’s Call bonus round. Whereas, four or more scatters, trigger the Down Below bonus game. They also give extra spins if they land in the bonus rounds.

Bonus Buy Options

If you reside in a region where bonus buys are allowed, then you will also have the bonus buy button enabled for your game play. Here there are 4 options to choose from:

BonusHunt FeatureSpins: this is an ante bet option that costs an extra 2x your betting stake. It awards a 5 times higher chance of triggering free spins.

Siren FeatureSpins: these spins guarantee to land at least 2 siren symbols on each spin. You need to pay an extra 9x on top of your betting stake for each feature spin.

Sirens Call Bonus Round: this option costs 120x your betting stake and guarantees at least 3 scatter symbols to trigger the Sirens Call bonus round.

Down Below Bonus Round: being the more lucrative bonus game, this option costs 400x your betting stake. So, you will have better chances to land bigger wins.

Beast Below Bonus Game

Beast Below comes with not one but two bonus rounds. Which one gets triggered, depends on how many scatters you land in the base game. For Sirens Call you need to land 3 scatters. If you land 4 or 5 scatters, then you trigger the Down Below bonus round. The main difference between the two bonuses is how the wilds behave.

Beast Below Down Below Bonus Free Spins

Sirens Call Free Spins

When you land 3 scatter symbols, you get 10 free spins with expanding siren wilds. Both yellow and pink sirens can land on any free spin. Pink sirens stay on the reels after expanding, nudging up one row with each spin, until they disappear. This is reminiscent of the nudge feature in Push Gaming’s Razor Shark and Fish ‘n Nudge games. Moreover, both sirens carry win multipliers up to 200x, which are combined, if more than one siren are part of a winning combo. You can re-trigger 2 or 3 extra spins, when landing 2 or 3 scatters, respectively.

Down Below Free Spins

When you land more than 3 scatters you trigger the Down Below Free Spins. Similar to Sirens Call, you get 10 free spins with active wild symbols. However, here you receive diver wilds with multipliers instead of siren wilds. These wilds always expand to cover an entire reel and come with 3 oxygen charges (lives), so they remain sticky until the lives run out. Diver wilds can move to adjacent reels at the start of each spin, consuming one live and changing their win multiplier. Multipliers up to 200x apply to winning pay lines using a diver wild. Here too, you can land multiple wilds per spin. When more than one wild lands and are involved in a win, then their win win multipliers are combined. You can re-trigger 2 or 4 extra spins, when landing 2 or 3 scatters, respectively.
