Prepare to plunge into the shadowy waters of Beast Below, a deep-sea adventure slot from Hacksaw Gaming where sirens and sea monsters guard immense treasure. Played on a 5x4 reel grid with 14 paylines, this slot offers expanding wilds, dual free spins rounds, and a chance to haul in a max win of 10,000x your bet.
Beast Below is played across 5 reels and 4 rows, with 14 fixed paylines where wins are formed by matching 3 to 5 identical symbols from left to right. Before diving in, select your bet using the controls—bets range from 0.10 to 100 per spin. Once set, hit the spin button and look for wild sirens, deep-sea beasts, and scatter symbols to activate bonus rounds. Low-paying symbols are standard card ranks (10 to A), while the high-value icons are the terrifying and majestic creatures of the deep.
This slot swims in moody underwater aesthetics, blending eerie deep-sea darkness with bioluminescent accents. The reels are surrounded by ancient ruins and mysterious lights, creating an immersive experience of something lurking just beyond visibility. The sirens—one golden, one pink—are central to the theme. The yellow siren dominates base game spins, while the pink version brings extra heat in bonus rounds. Each expansion, multiplier, or bonus trigger is highlighted with sleek animations and aquatic effects that keep the pace flowing.
Beast Below boasts two types of expanding wilds, two distinct bonus rounds, and a range of special mechanics that tie beautifully into the deep-sea setting.
There are two types of wild sirens:
Yellow Siren: Appears in the base game only. When it helps form a win, it expands upward on its reel and applies a random multiplier from 2x to 200x.
Pink Siren: Exclusive to the Sirens’ Call bonus. When it lands, it sticks to its reel and expands. However, it gradually nudges upward off the screen with each spin. This version also delivers a 2x–200x multiplier.
Activate this powerful bonus by landing 4 FS scatters, granting 10 free spins. In this mode:
Diver symbols can land randomly and expand to fill entire reels.
Each diver comes with a 2x–200x multiplier and a countdown number showing how many spins it will remain on the reel.
When multiple divers contribute to a win, their multipliers combine, potentially creating huge payouts.
