Beast Below

Beast Below is an underwater-themed slot from Hacksaw Gaming, played on a 5x4 grid with 14 paylines. Its main mechanics revolve around expanding wild characters, with Sirens appearing in the base game and Divers taking over during the Down Below bonus.

Both character types can carry multipliers of up to 200x. The game data lists volatility at 4 out of 5, a maximum win of 10,000x, and four possible RTP settings.

Yellow Sirens are the base-game wild symbols. A Siren expands upwards to the top of the grid when that expansion would make it part of a win. It then applies its displayed multiplier to any winning payline passing through it.

Siren multipliers can reach 200x. If several Sirens appear on the same winning payline, their values are added together before the combined multiplier is applied to the payout. Yellow Sirens are not persistent and disappear after each spin.

Landing three FS symbols in the base game triggers 10 Sirens' Call free spins. Sirens have a greater chance of appearing during this round, and the usual Yellow Sirens can be joined by special Pink Sirens.

Pink Sirens use the same 2x to 200x multiplier range as Yellow Sirens, but they are semi-persistent. Once a Pink Siren expands, it remains in that reel position and nudges off the grid one row at a time.

The feature can be retriggered. Two FS symbols award two additional spins, while three FS symbols add three spins.

Four FS symbols in the base game trigger the Down Below bonus with 10 free spins. This feature replaces the Siren focus with Wild Divers that always expand fully when they land, covering an entire Diver Reel.

Each expanded Diver starts with three Oxygen Charges and disappears when its Oxygen reaches zero. A Diver may move to an adjacent reel at the beginning of a spin, consuming one Charge. Its displayed multiplier can also change when it moves.

Divers carry multipliers of up to 200x. When multiple Divers contribute to the same win, their multiplier values are added together and the combined value is applied to the corresponding payout. Up to three Divers can be present at once.

Retriggers differ from those in Sirens' Call. Two FS symbols add two spins, while three FS symbols award four additional spins.

Beast Below includes a Bonus Buy option that provides direct access to either of its two bonus features. No purchase prices are specified in the supplied game data.

There are also two FeatureSpins™ choices, both of which increase the bet size. BonusHunt FeatureSpins™ improve the chance of triggering a bonus, while Siren FeatureSpins™ guarantee that at least two Siren symbols appear somewhere on the reels.

Hacksaw Gaming lists four RTP settings for Beast Below: 96.29%, 94.27%, 92.25%, and 88.28%. The presence of several figures makes the RTP configuration an important detail when reviewing a particular version of the slot.

Volatility is rated 4 out of 5. The maximum win is listed as 10,000x, with both Sirens and Divers able to contribute individual multiplier values of up to 200x.

The demo provides a useful way to follow the multiplier rules without losing track of the character mechanics. In the base game, watch for Yellow Sirens that expand only when doing so creates part of a win, then note how multiple Siren values are added on a shared payline.

The bonuses have clearly different forms of persistence. Pink Sirens remain where they expanded before nudging away one row at a time. Divers instead occupy full reels, use Oxygen Charges, and may move to an adjacent reel with a different displayed multiplier.

Beast Below builds its 5x4, 14-payline format around two related wild systems. Sirens expand upwards and can become semi-persistent during Sirens' Call, while the Down Below bonus introduces full-reel Divers governed by Oxygen Charges.

The key specifications are a 4 out of 5 volatility rating, RTP settings ranging from 88.28% to 96.29%, and a 10,000x maximum win. Bonus Buy and FeatureSpins™ provide additional ways to access or increase the frequency of the main mechanics.
