Dark Vortex — RTP, volatility and max win

Dark Vortex by Yggdrasil pulls you into a gothic horror world of demons, ghosts and monsters, painted in dark blue, grey and violet. Wins count in both directions here, and the game switches between different reel sets.

Dark Vortex came out on October 24, 2018 and sits among the mystic fantasy titles from Yggdrasil. Its 5×3 grid holds 243 ways, and the reels mix stacked symbols with wilds, scatters and dedicated bonus symbols. The stake range is €0.10 to €50.

High volatility with a max win of more than seven thousand times the stake makes Dark Vortex a game of long dry spells and rare big hits; equally risky games are listed under inferno slots by volatility.

The 5×3 grid offers 243 ways: matching symbols need to land on adjacent reels, and the row they sit in does not matter. Because Dark Vortex pays both ways, a combination counts from the leftmost reel as well as from the rightmost one. Stacked symbols can cover whole reels and link several ways at once.

In the base game symbols arrive in stacks, and wins count in both directions across the 243 ways. Scatters and bonus symbols are what open the extras.

The extras are free spins and a separate bonus game. Dark Vortex also switches reel sets, so the reels are stocked differently and a different mix of symbols and stacks reaches the grid.

Alongside its bonus game and changing reel sets, Dark Vortex has a free spins round; other Inferno titles with a free spins round, and how each one triggers, are collected under inferno slots with free spins.

RTP 96.5%, higher than 86% of the 400 Inferno slots. Background: how RTP works on a slot. Volatility High, like 66 of the 114 slots in the Demon theme. Background: what slot volatility means. Max win 7,318× (€365,900 at the highest stake). Background: what max win means on a slot. Hit frequency 28.3%: roughly one spin in 4 wins.

With 7,318× as its ceiling it outruns 67% of the Inferno slots, and a 96.5% return is generous for a game this volatile.

High volatility fits the design: much of the potential sits in the free spins and the bonus game, while the base game with its stacks and both-way pays supplies the smaller hits.

Dark Vortex is offered at more than one return level, and the highest one is among the stronger figures in the catalogue; where other titles sit is laid out on the RTP of inferno slots page.
