Goldstorm Ultra

Yggdrasil channels a Vegas-style slot-machine look into Goldstorm Ultra, running a bright arcade paytable across the reels — playing-card suits, a dollar icon, coloured bars, lucky sevens, bells, stars and the game's own branded logo — backed by an electronic soundtrack built for a casino-floor feel.

The base game and regular free spins play out on a single 5x3 grid with 20 paylines, while super free spins runs two 5x3 areas at once. Combinations need three or more matching symbols starting from the leftmost reel, and five-of-a-kind hits pay between 1.25x and 25x the bet depending on the symbol.

Wilds land only on the middle three reels, in both the base game and the bonus rounds, substituting for every symbol except scatters. Each wild carries a random multiplier — 2x, 3x, 4x or 5x — that applies to the win on whichever payline it forms part of; when several wilds appear in one winning combination, their multipliers combine into a single total before it's applied.

Two collection meters run simultaneously in the base game: a green meter feeding regular Free Spins and a pink meter feeding Super Free Spins, each needing 50 scatter symbols to fill, with progress tracked at the current bet level and any excess carrying over once a meter empties. Up to five scatters can land on a single spin, and either meter can be topped up at any time.

Filling the green meter triggers 10 Free Spins, played across two gaming areas of which only one is active at a time. Both meters stay live during the round — collecting 14 more green scatters retriggers 5 extra spins, while collecting 14 pink scatters instead upgrades the round into Super Free Spins and adds 5 spins on top. Wilds turn sticky for the rest of the round once either bonus mode begins. Filling the pink meter directly in the base game skips straight to 10 Super Free Spins, or adds 5 to an already-running Free Spins round, where both gaming areas stay active but only the pink meter keeps collecting; reaching 40 pink scatters during this stage adds a further 5 spins.

Two feature buys are available: 53x the bet for direct entry into Free Spins, or 87x the bet to jump straight into Super Free Spins. Goldstorm Ultra runs three RTP configurations topping out at 96%, alongside high volatility, a 21.33% hit frequency, a bet range of 0.20 to 70, and a maximum win of 4,000x the stake. Released in September 2025, its two-tier meter system means the base game is always building toward one bonus or the other, with the balance between green and pink scatters deciding whether a session lands in the smaller Free Spins round or escalates into the double-grid Super Free Spins.
