Are you ready to slay dragons in the name of metal?

Stand alongside Dio’s legendary lead vocalist, Ronnie James Dio, where he sits on the throne of a once mighty castle. In an instant, a circling dragon dashes for the foreground, setting surroundings alight with one fiery breath…

Team up with Dio, using the powerful source of metal music to conquer this deadly fire-breathing dragon, prowling wild wolves and more – All while listening to Don’t Talk to Strangers, Evil Eyes, and We Rock through the juke box.



The most dangerous of the dragons is Murray, who serves as the Scatter symbol. Catch three Murray symbols to trigger the free spins and unlock your way into the castle. Your showdown with the dragon is about to begin, to the soundtrack of Dio’s most epic song Holy Diver.<

During this feature, you’ll have multiple ways to win: Land Sticky Wilds in the Wild One feature, which will remain on the reel for the duration of the Free Spins feature; or land the Special symbol to unlock different doors to the castle.

Behind those doors are three different features:

In the Fallen Angel feature, an additional falling Wild will appear at the top of reel 1; in the Wild Multipliers feature, an additional random multiplier will be added to a Sticky Wild; in the Symbol Upgrade feature, high-paying symbols will be immediately upgraded to the highest-paying symbol as Dio moves along the reel at the top so you can see him progress through his quest.

Wolves prowl around the castle and serve as the Wild symbol. When you catch one of these Wilds in the Lock Up the Wolves feature, a cage will close around it, and another open cage will appear in the next reel. Catch more wolves continuously to receive Re-spins. Collect magical orbs along the way to change Wilds to Multiplier Wilds!

Get ready for a fantastical celebration of Dio’s legacy in a game full of heavy metal, killer features, and fire-breathing dragons!
