Fortuna

Sunken ruins glow with cold bioluminescence in Fortuna, where something enormous stirs between forgotten monoliths. Turquoise deep-sea light, tentacles and elder signs surround a classic 5x3 layout with 10 paylines. Descend into the submerged world, follow the symbols across the reels and watch for the Grimoire of the Deep, an ancient book with two roles in the game.

The Grimoire of the Deep acts as both a wild and a scatter in Fortuna. This dual function makes the book central to the regular reel action and the route into the bonus. Land 3 or more Grimoires anywhere on the reels to trigger 10 free spins. The books do not need to appear on a particular payline to open the feature, so watch each reel as the symbols settle beneath the waves.

Before the free spins round begins, one symbol is selected at random to become the special expanding symbol. This selected symbol is the one to follow during the feature. Whenever it lands, it stretches across every position of its reel, changing that reel into a complete column of the same symbol. The expansion makes the chosen symbol easy to identify against the dark ocean floor and glowing ruins. Every reel expansion sends another pulse of turquoise light through the submerged chamber.

In Fortuna, the special expanding symbol can pay even when the reels carrying it are not next to each other. Follow its appearances across the five reels and see which reels expand into full columns. The feature applies its payment across the 10 paylines, connecting separated reels whenever the selected symbol forms a qualifying win. This gives each landing of the special symbol a visible effect on the 5x3 board.

The free spins round uses the same classic reel structure, with the randomly chosen special symbol driving its expanding action. Each spin provides another arrangement to inspect, while the Grimoire remains the key that unlocked the feature. The familiar imagery of tentacles, elder signs and ancient structures stays present throughout, framing the selected symbol as it fills entire reels and contributes across the paylines.
