Wolf Fang - Underworld

Facts

About the game

Candles, skulls and a moon above the reels

Spinomenal released this instalment of the Wolf Fang series on 17 February 2023. The setting is markedly grimmer than most wolf slots manage: skulls, candles, snakes and birds, with black and darkness as the base tone and the moon as a fixed emblem.

Underworld is a variation within a running series; atmosphere is the element reworked here.

You choose what the bonus looks like

The striking entry in the feature list is Free Spins Mode Choosing: when the free spins land, you select from several variants. In practice that means weighing more spins against heavier spins.

Beyond that the game runs stacked symbols and a Wild, and further free spins can be added during the round. There is a buy feature too. How many variants exist is not published.

The figures: 95.85%, medium-high, 2,000x

The stated RTP is 95.85%, just under the 96 many players treat as a line. The data notes that the studio ships several RTP settings, so check the game information for the percentage your casino runs.

With medium-high variance and a 2,000x maximum, this title sits deliberately in the middle ground. You are not chasing a record; you are playing for a bonus round that lands often enough to keep the game moving.

What the choice does to your session

Stake limits and the line count are not published. What you can steer is the risk profile inside the game itself, and here that is unusually concrete.

Pick the variant with many spins and you press the spread down. Pick the heavy variant and the game turns all-or-nothing while the ceiling stays at 2,000x. So do not make that choice on autopilot.

Suited to players who like to decide

This game fits anyone who wants something to steer and does not want every round to run identically. The choice at the start of the bonus gives exactly that.

Anyone after a high ceiling is in the wrong place: 2,000x is modest. And anyone who dislikes menus mid-game will be interrupted every time.

Beside Book of the Night Wolf from the same studio

Spinomenal supplies two wolf titles to this catalogue that stand as opposites. The book title carries 96.01% and 10,000x, but a single fixed round with no choice.

Underworld trades that ceiling for control and a calmer profile. Would you rather choose, or rather wait?

RTP, volatility and max win

Verdict

Wolf Fang - Underworld is the sensible side of Spinomenal's wolf output. A grim setting, stacked symbols, and a bonus round whose shape you choose rather than simply receive. At 95.85% RTP, medium-high variance and a 2,000x maximum, everything stays within reasonable bounds: no outliers, but a game you can sustain across an evening. The choice function is the reason to play it; the modest upper limit is the reason not to expect anything grand from it.
