Beast Below Demo & Review

Beast Below review

Beast Below is a 5x4, 14-payline deep-sea slot from Hacksaw Gaming. Sirens are the stars of the base game: these wilds expand upwards to the top of the grid whenever expanding would make them part of a win, and they carry multipliers up to 200x. If several sirens share a winline, their multipliers are added together before being applied.

Only yellow sirens appear in the base game, and they vanish after each spin. Three FS symbols award 10 Sirens' Call free spins with better odds of sirens, and special pink sirens can appear with semi-persistent behaviour, while divers join the hunt for the Beast in the bonus. Hacksaw rates it 4 out of 5 for volatility with a 10,000x maximum. The top RTP is 96.29%, but operators can choose versions as low as 88.28%, so check the info screen.

Beast Below RTP, volatility and max win

RTP: the default return to player is 96.29%, meaning that over a very large number of spins the game is designed to pay back around 96.3 units for every 100 wagered. It is also offered at 94.27%, 92.25%, 88.28% – a casino running the lowest version keeps noticeably more of every bet. How RTP works.

Volatility: Beast Below is a high volatility slot: expect longer stretches between meaningful wins and larger swings in your balance than on a medium-volatility game. The bonus round carries much of the game's value. Volatility explained.

Max win: the maximum payout is 10,000x the stake. What max win really means.
