The Great Hall of Spins (Free Spins & Multipliers)

As you repeatedly activate the progressive bonus round known as the Great Hall of Spins, you will be able to unlock increasingly bigger rewards. Every level has special features to increase your earnings and is associated with a particular Norse deity.
