How to play Beast Below mobile slot

The Beast Below slot hits all the sweet spots: 10,000x your bet, a high RTP of 96.29% and two bonus free spins features. So what’s with the 3-star slot review?

This Beast Below mobile slot looks beautiful, as we’ve come to expect from Hacksaw Gaming; you have an eery slot from the get-go as you fish deep dark water on 5×4 reels and 14 paylines.

The Ace to 10 looks weathered and seaweed-ridden, while the five gloriously toothy monsters as your bigger catch on the reels, with the anchor as the highest-paid symbol of the lot. It’s far grimier than even the Fear the Dark slot.

You get expanded wilds in the base game and the two free spins bonus, but it’s the bonus feature where you get the big multipliers and the big wins.

The Beast Below online slot is good

As we said, it’s hard to fault this Beast Below slot game. It looks great, and the bonuses are fun and imaginative.

3 scatters set you ever further down below, where you get more expanded wild sirens and a new Pink Siren that stays sticky on screen for up to three nudges with up to 200x multipliers.

All sirens come with multipliers and will be added together to help create big wins. So two sirens with a 200x multiplier give you 400x your paytable win.

4 scatter takes you to the bottom of the ocean where the Kraken awaits. You’ll have walking wilds in the form of divers who will walk the screen for up to 3 turns with equally larger multipliers.

So what’s the problem

The problem, as we kept playing, is the 14 payline and the very weak paytable. So weak. There’s a reason you need 200x multipliers to make things interesting.

It makes the base game incredibly boring, even with expanded wild multipliers, and a little slow.

Thank god for the Superbet option where for 3x your bet, you can increase your odds of catching the bonus games by up to 5x.

Still, if the game had just given us that math, with, say 30 paylines instead of 14 (or a better paytable), it would have been a better game.

As it stands, you can play the dangerous game of paying extra to hit the features or play a high variance game where what you see is what you get: ie. King Carrot slot. We know what we prefer, but now you have options too.

Bonus Features

Expanded Wild: The sirens are the wild symbols that expand upward to the top of the reel if they can create a win. Each expanded wild will have a multiplier of 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x, 15x, 20x, 25x, 50x, 100x, or 200x your bet.

If more than one sirens are part of a win, the slot will first add the multiplier values together and then apply them to the win.

The Siren's Call Bonus Game: 3 Kraken Free spin scatters symbols will trigger 10 free spins. You get a higher chance of catching the expanded siren symbols and the addition of the Pink Siren wild.

The Pink Siren wild expands and stays sticky on screen but is gradually removed by nudging one row upward on each subsequent free spin. The Pink Siren can have a bigger multiplier of 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x, 15x, 20x, 25x, 50x, 100x, 200x.

Landing 2 scatter will trigger +2 spins, whilst 3 scatters will trigger +4 spins.

Down Below Bonus Game: Land 4 scatter symbols in the base game to trigger 10 free spins. During this bonus, you now get a new wild bonus: the diver.

When he lands, he covers the whole reel and walks around the reels for up to 3 turns until the oxygen runs out. When he reaches 0, he runs out.

You only get the Pink Siren multipliers on the Divers of 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x, 15x, 20x, 25x, 50x, 100x, or 200x. If you get two or more divers on screen, the multipliers are added together before being applied to the win.

Landing 2 scatter will trigger +2 spins, whilst 3 scatters will trigger +4 spins.

Buy Bonus: You can buy a variety of bonus features.

  • Bonus Hunt Feature Spins - RTP 96.29% +3x your bet: Each spin is 5x more likely to trigger a bonus game.

Beast Below Review Conclusion

The Beast Below slot is a very volatile 5 reel 4-row game with only 14 payline, leaving you with few wins in the base game. It can feel very slow as you wait for the bonus features to wait.

This is why it's worth adding 3x to your bet to increase your chance of getting the bonus games. If you don't, you might end up drowning with these monsters.

It does make the minimum bet of this game 0.30 instead of 0.10 - so bear this in mind when you play. Not a huge top-up, but also not as satisfying as the Superbet option of slots like Golden Fish Tank 2 where you get more tangible features for the cost.

However, with a top win of 10,000x your bet, big-time gamblers will want to take a few spins into these dangerous waters.
