Gameplay and Features

The Dio Killing the Dragon online slot truly reveals its heavy metal abilities during the bonus features. While the free spins bonus is the highlight, don’t underestimate the winning power when the wolf wild lands as these can easily line up massive combinations and trigger re-spins when you least expect it!

Lock up the Wolves Feature

Wild symbols appear on any reels as the highest paying and having the ability to represent anything else when a winning combination is possible, excluding the scatter symbols, of course.

During standard spins, a golden open cage appears around the first reel, which activates the lock up the wolves feature. Asd the wolf lands, the cage closes around it and locks it in place, meaning it comes a stick wild for one re-spin. During the re-spin another cage will show on reel two and if another wild lands, both become sticky wilds. The process repeats for as long as additional wild symbols land on successive reels, creating massive combinations with each spin.

Free Spins feature

The free spins feature offers the best max win opportunities when at least three of the red monster scatters appear at the same time. This activates six free spins while four scatters would activate eight free spins and five scatters would trigger ten spins.

During the feature, the open cages appear on reels two, three and four, making it possible to capture more wolves and have the advantage of sticky wild symbols for the following free spin and the rest until the bonus ends. A special symbol can also appear on the fifth reel to add even more benefits, including:

  • Wild Multiplier: If the X appears in the special symbols, a multiplier is added to the sticky wilds currently locked on the reels. With the win multiplier increased, players will receive at least double the reward for combinations it appears in.
  • Symbol Upgrade: If the sword appears, symbol upgrades will activate and increase the value of a selected symbol. All the same symbols will upgrade to a higher value before combinations reward.
  • Fallen Angel: If the angel wings are selected, the game applies a wild to the top of reel one. This symbol will then shift down one position to represent more symbols. The falling wild will remain activate for three spins until it falls off the bottom of the reel.

Once the special symbol appears, the game also adds another two bonus spins to the remaining balance. Therefore, not only will you gain special features, but also additional spins to claim the max win!
