Any horizontal or vertical line of 3 or more matching symbols constitutes a winning combination. A single row or column can contain multiple wins, and wins can intersect or overlap on the same row or reel.

When a Hero symbol creates a win, all remaining symbols of the same type turn into Wilds. The Hero Wilds feature can be activated in both the main game and Free Spins. Wild symbols substitute for all symbols, except Scatter symbols.

This feature is activated randomly when there is no win. During this feature, only symbols of one colour remain on the reels, while all other symbols, except Scatter symbols, are destroyed.

This feature is activated randomly after a no-win situation. During the feature, only symbols of one colour remain on the reels, with all other symbols, except for Scatter symbols, being destroyed.

There are 3 Free Spins worlds, each with a unique feature: • Dark Forest: Spreading Wilds • Ice World: Heavy Wilds • Fire Lands: Random Wilds In Ice World, when a Captain or Boss’ weak spot is destroyed, a stack of 2 Heavy Wilds is randomly placed on the reels. If part of a winning combination, Heavy Wilds remain for the next Avalanche™. In Fire Lands, 2 to 4 Random Wilds are randomly placed on the reels after a weak spot is destroyed. In Dark Forest, a Spreading Wild is randomly placed on the reels after a weak spot is destroyed, completing a win and generating new Spreading Wilds on adjacent positions.

Each Hero has corresponding low and medium win symbols that activate their Hero Attack and charge the Hero Meter. It takes 3 charges to fill the Hero Meter, with each win on a Hero symbol contributing to the charge. Once a Hero Meter is full, the Hero Special Attack is activated.

Each Hero has a corresponding low and medium win symbol which will be used to activate its Hero Attack and charge its Hero Meter. The Blue Hero Special Attack deals 1 damage point to all Monsters. The Red Hero Special Attack deals 1 damage point 4 times to randomly selected Monsters. The Green Hero Special Attack deals 4 damage points to one random Monster.

There are 2 types of Monsters in the game: 3 Captains and the Boss. Captains: 15 health points; award a Free Spins feature when destroyed. The Boss: 105 health points; when destroyed, it transfers the player to another Free Spins world with 8 free spins and new Captains.
