The paysymbols that appear in view are low-value royals followed by better paying fantasy creatures in different colours, and the Dark King himself. The magical orb is the wild that acts as a symbol substitute. The number of wilds you land in one spin determines the awarded multiplier. The red gem in a golden skull frame is the scatter that triggers the free spins round.
Land 3, 4 or 5 scatters to get 10, 12 or 15 free spins, respectively. Before the free spins round commences, a Sticky Wilds Hot Spots area is designated on the middle reels. Any wild that appears within the area turns into a sticky wild for the feature duration and adds 1 free spin to the tally.
*The Dark King: Forbidden Riches slot is still in the works and some in-game details might be missing or incomplte. We will update this review once more information emerges.
