Introduction
Named after the album by Dio, this slot celebrates heavy metal music and a fantasy world full of dragons and wolves. If you’re not a heavy metal fan, you may not have heard of Dio before, but they’re an American rock band who were formed in 1982. Two of their founder members, Ronnie James Dio and Vinny Appice, were in Black Sabbath but left the band after a disagreement.
Dio Killing the Dragon is played on a 5-reel by 3-row game grid and offers 243 ways to win, as well as a free spins round with 3 different modifiers. It’s part of Play’n Go’s collection of music themed slot games, joining titles such as Alice Cooper and Tome of Madness and Kiss Reels of Rock. But does it make sweet music on the reels? We’ve already given it a try and can tell you the highs, lows, sharps and flats in our full Dio Killing the Dragon slot review.
Theme, Graphics & Soundtrack
This slot machine game is a no-holds-barred celebration of Dio’s 2002 album ‘Killing the Dragon’ and invites you to stand with the band’s frontman, Ronnie James Dio, as he looks over the ruins of a once powerful castle. A dragon circles above, and only the power of music can defeat him. So grab your axe (in a guitar sense) and help Dio destroy the dragon.
The graphics are dark and moody and match the theme perfectly. There are wolves, monsters, and a very heavy metal vibe. You can also choose between 3 background tracks in the game: ‘Don't Talk To Strangers', 'Evil Eyes', and 'We Rock'. Weirdly, none of these are actually from the Killing the Dragon album, but it’s a pretty cool idea.

FAQs
What is the Lock Up the Wolves feature in Dio Killing the Dragon?
When you’re playing, you’ll notice several cages on the reels. If a wolf wild symbol lands in the cage on the first reel, you’ll be given a free respin, and the wolf will become sticky. An open cage is added to the second reel for hopefully another wolf to fill. If it does, this triggers another respin and another sticky wild. This can go on for a maximum of 4 turns.
What is the top-paying symbol in Dio Killing the Dragon?
The wild symbol, a ferocious red-eyed wolf, is the highest-paying symbol in the whole game and offers a top prize of 2x for landing 5 consecutive symbols, and a low prize of 0.7x. The game symbols don’t have huge payouts, but the maximum top prize in the game is a very respectable 15000x.
What is the volatility of Dio Killing the Dragon?
Dio Killing the Dragon is a highly volatile slot machine, so you can expect to see extended periods of losses in between wins. It does offer the potential for bigger wins when they do arrive, though. High-volatility video slots are especially good for more experienced players or those looking for a larger win potential.
