Beast Below

Underwater wilds that expand, carry multipliers up to 200x, and survive across multiple free spins make Beast Below one of Hacksaw Gaming's more layered ocean-themed slots. The 5x5 grid runs 14 paylines, with Siren Wilds that expand upward on win and apply their multipliers to any line passing through them. A second bonus mode, Down Below, features Diver Wilds that move across reels over time. With a 94.27% RTP, a 10,000x max win, and a bonus buy option, the game suits players who want expanding-wild mechanics with deep-sea visual texture.

What is Beast Below?

Beast Below is a 5x5 video slot from Hacksaw Gaming with a 94.27% RTP, medium-high volatility, and a top win of 10,000x the bet. Its standout mechanic is the Siren Wild: an expanding wild that grows upward to fill the entire reel column when it contributes to a win, carrying a multiplier between 1x and 200x that applies to all wins passing through it.

Hacksaw Gaming released Beast Below in March 2023 and structured the bonus system around two distinct modes accessible via scatter count. Three Scatter symbols award the Sirens' Call free spins, where Siren Wilds appear more often than in the base game. Four Scatter symbols unlock the Down Below bonus, where Diver Wilds expand fully on landing and then drift between adjacent reels over subsequent spins, consuming Oxygen Charges before disappearing. The bonus buy option lets players skip the base game and purchase either bonus mode directly.

1. Open Beast Below at Wild.io and choose your bet size. The bonus buy option is available to purchase free spins directly.
2. On the 5x5 grid, Anchor Wilds can land on all five reels and substitute for any pay symbol. An Anchor Wild pays 20x the bet for a five-wild payline.
3. When a Siren Wild lands and forms part of a win, it expands upward to fill the entire reel column. The Siren carries a multiplier between 1x and 200x that applies to every winning combination passing through the column.
4. To trigger the Sirens' Call free spins bonus, land 3 Scatter symbols. Siren Wild frequency increases during these 10 free spins.
5. Land 4 Scatter symbols to unlock the Down Below bonus, where Diver Wilds land and fully expand immediately, then move to adjacent reels over subsequent spins, consuming 1 Oxygen Charge per move before disappearing.
6. Track Diver Wild positions carefully: each Diver has 3 Oxygen Charges, and their movement across adjacent reels determines which columns carry wild coverage on each spin.

Beast Below Slot Theme & Graphics

Beast Below puts five deep-sea creatures on the reels of a 5x5 grid framed in coral and bioluminescent light. The ocean floor setting uses blues, greens, and blacks as its base palette, with the Siren Wild symbols rendered in a contrasting luminescent gold that makes their expansion animation immediately visible. Anglerfish, sharks, and pufferfish are illustrated with enough character detail to feel specific rather than generic ocean filler.

The Diver Wild in the Down Below bonus is animated with a swimming motion that carries across the grid as it moves between reels, and the Oxygen Charge indicator stays visible above each Diver position. Sound design matches the deep-sea environment: low ambient tones in the base game that shift to urgent strings when Siren Wilds expand or Diver movement triggers. On mobile, the 5x5 layout is readable and the expanding wild animations scale well without crowding the grid.

Beast Below Slot Symbols & Paytables

Beast Below uses a two-tier pay symbol set anchored by deep-sea creatures, with two distinct wild types that behave differently from one another.

Low Value Symbols

Low-value symbols in Beast Below are the card ranks 10 through A. They fill the 5x5 grid at high frequency and contribute to the 25.45% hit rate. In payline terms their base win is small, but when a Siren Wild expands upward through a column where card ranks sit on adjacent reels, the Siren's multiplier applies to any winning combination formed. Card-rank symbols are also the likeliest symbols to complete a win line that crosses through a Diver Wild's column during the Down Below bonus, giving them indirect importance during the bonus sequences.

High Value Symbols

High-value symbols include the anglerfish, shark, pufferfish, and three additional deep-sea creature icons. These are the premium symbols worth targeting when Siren Wilds are active. The specific payout for five matching premiums on a payline is visible in-game, and the combination of a top-tier premium landing alongside an expanded 200x Siren Wild is where the game's largest single-spin wins originate. The Anchor Wild pays 20x for a five-wild line and acts as a standard substituting wild across all five reels.

Special Symbols

The Anchor Wild appears on all five reels, substitutes for any pay symbol, and pays 20x the bet for five wilds in a line. The Siren Wild appears on the grid and expands upward to cover the full reel column when it contributes to a win. Sirens carry a multiplier between 1x and 200x that applies to every win passing through their expanded column. The Diver Wild in the Down Below bonus lands as a full-column expanding wild, holds 3 Oxygen Charges, moves to an adjacent reel at the start of each spin (consuming 1 Charge), and disappears when Charges reach zero. Scatter symbols trigger the bonus modes: 3 Scatters award Sirens' Call free spins, 4 Scatters award the Down Below bonus.

Beast Below Bonus Feature & Special Features

Siren Wild

The Siren Wild is the primary expanding wild in Beast Below. When a Siren lands anywhere on the 5x5 grid and forms part of a winning combination, it immediately expands upward to fill the entire reel column from its landing position to the top row. Each Siren carries a multiplier value between 1x and 200x, and that multiplier is applied to every winning combination passing through the Siren's expanded column. Multiple Sirens landing in different columns on the same spin each apply their individual multipliers to wins crossing through their respective columns. In the Sirens' Call free spins mode, Siren Wilds appear more frequently than in the base game, giving the multiplier mechanic more opportunities to activate across 10 free spins.

Sirens' Call Free Spins

Landing three Scatter symbols anywhere on the 5x5 grid triggers the Sirens' Call free spins bonus, awarding 10 free spins. During this round, the odds of Siren Wilds appearing on the grid increase compared to the base game, meaning more spins benefit from expanding-column wild coverage with multipliers up to 200x. Any Siren that expands during free spins applies its multiplier to all wins in that spin, and with higher Siren frequency, multiple expanded columns can align in a single free spin. This mode targets the 10,000x max win ceiling through stacked Siren multipliers across high-value symbol combinations.

Down Below Bonus

Landing four Scatter symbols triggers the Down Below bonus, a distinct mode that replaces Siren Wilds with Diver Wilds. When a Diver Wild lands on the 5x5 grid, it always fully expands to cover the entire reel column immediately. Each Diver starts with 3 Oxygen Charges. At the start of every subsequent spin, active Divers move to an adjacent reel, consuming 1 Oxygen Charge per move. When a Diver's Oxygen Charges reach zero, it disappears from the grid. Multiple Divers can be active simultaneously, drifting across adjacent columns over the course of the bonus. The persistent, shifting wild coverage distinguishes Down Below from the Sirens' Call mode: wins come from tracking Diver positions and aligning premium symbols with the moving expanded columns.
