When there's a win on a Hero symbol, all remaining symbols of the same type turn into Wilds.

In this feature, only symbols of one colour remain on the reels – all others are destroyed, except for Scatters.

Three Scatter symbols appearing anywhere on the reels in the main game activate 8 free spins. There are 3 free spins worlds, each with its own feature: Dark Forest (Spreading Wilds), Ice World (Heavy Wilds), and Fire Lands (Random Wilds). At the start of Free Spins, players spin the wheel to determine which Free Spins world they will enter.

Heroes and Monsters are present in Free Spins. The Heroes attack Monsters.

To activate the Free Spins feature, the Heroes need to destroy any of the Captains or any of the Boss' weak spots.

A stack of 2 Heavy Wild symbols is randomly placed on the reels. If they form part of a winning combination, they will complete it and then be destroyed. If they don’t contribute to a win, they will disappear with the next Avalanche™.

Between 2 and 4 Random Wild symbols are placed on the reels. If they form part of a winning combination, they explode along with the other symbols. Any new symbols landing in their place will also turn into Wilds. If the Random Wilds don’t contribute to a win but a win occurs elsewhere, they remain on the reels for the next Avalanche™.

A Spreading Wild is randomly placed on the reels. If it completes a winning combination, it explodes along with the other symbols. New Spreading Wilds are then generated in adjacent positions to the one that exploded. Each Spreading Wild can generate up to two additional Spreading Wild symbols.

There are two types of Monsters in the game: three Captains and one Boss. Each time a Captain is destroyed, the Free Spins feature of the current Free Spins world is activated. The Boss can only be damaged once all Captains have been defeated.

Each Hero has a corresponding low and medium win symbol, which are used to activate their Hero Attacks and charge their Hero Meters. Each Hero launches a random, individual Hero Attack against a Monster.

There are 3 special Hero Meters, 1 for each Hero. 3 charges are required to fill each Hero Meter. If the Hero Meter is full after all regular attacks, the corresponding Hero Special Attack will activate. The Blue Hero Special Attack – 1 damage point to all Monsters. The Pink Hero Special Attack – 1 damage point 4 times to randomly selected Monsters. The Green Hero Special Attack – 4 damage points to one random Monster.
