Special Symbols

Second Chance is triggered by landing 3 scatters for respins on the missing reels. There’s also a better chance to land a 4th scatter.

The Ice Wall

Land 3 scatters for infinite free spins until the wild wall reaches the top row of any reel. One wild is added to the bottom row of the wall on the first spin. Then a new wild is added to the wild wall. Landing a hammer removes the current top row of the wall and adds a 1x to 5x multiplier.

Ymir’s Fortress
