Throughout history, only a few select musicians can truly be called game-changers. We’re talking about singers and stars who have reinvented a genre or pushed the boundaries of music. Elvis Presley was one such icon, and so were The Beatles and Michael Jackson. When it comes to heavy metal, Ronnie James Dio is the name that first springs to mind. A legendary singer who fronted numerous bands, including Black Sabbath and Rainbow, his legend lives on thanks to Play’n GO’s slot Dio - Killing the Dragon, named after one of his biggest hits.

If you’re finding references in the name with the famous legend of Saint George and the Dragon, you’re right. Dio is replacing the saint in the slot, however, using his metal powers to slay through the armies of Hell. It’s all brought to perfection in this epic Play’n GO tale starring one of heavy metal’s legends.

Specs-wise, it’s a slot with 243 winning ways, high variance, and an RTP of 96.25%. It’s a slot that’s just as explosive and exciting as the name suggests, so you’ll definitely want to give it a try for free or real money at the best slot sites.

The Dio - Killing the Dragon slot has a 5x3 layout that’s familiar, but a bit differently aligned. We have to credit Play’n GO with (once again) the great visuals. Dio is represented as St. George himself, holding a white-flaming sword in his hand. He also has a wooden shield to complete the picture. Not surprisingly, Dio is the highest-paying premium too.

Three other monsters join him on the premiums set, paying up to 1x for five. A hellish Wolf is the game’s Wild, substituting for other symbols in winning combinations and triggering one of the key features. It’s also the highest-paying symbol, doubling any win it’s a part of. This is a slot that’s full of fun features, so it might be worthwhile to check the guide and the paytable.

You can play the Dio - Killing the Dragon slot on any Android or iOS device. It was developed on the HTML5 platform, so you can easily play it from a mobile browser at the casinos on mobile, with no app download required.

Before you set sail on this unusual heavy metal adventure, you’ll need to place a bet. You can choose from $0.10 to $100 per spin – the typical range for most Play’n GO slots. The slaying begins a bit later, with the base game being pretty basic. However, the action picks up when you land a Wolf Wild in the open cage on the first reel, which triggers the Lock Up Wolves feature.

In this feature, the Wild is locked on the reels and moves on the second. As long as you land new Wilds in the open cages, this process repeats. Of course, you shouldn’t expect to land Wilds so easily due to the game’s high volatility. But, you can score big with it, more so that Wilds are the highest-paying symbol that can create rewarding win combos.

Like in most slots with free spins, you need three or more Scatters to trigger the Bonus Round, getting six, eight, or twelve free spins for 3, 4, or 5 Scatters, respectively. This is where things get really fun. A cage will be placed on the three middle reels, and as expected, any Wilds that land in it turns sticky. On the fifth reel, a new special symbol can land, awarding a pair of spins and one of three unique modifiers.

• Symbol Upgrade: upgrades the lowest-paying symbol to Dio. If all monsters are upgraded, Dio slays the dragon for massive payouts
• Fallen Angel: a Wild lands on top of the first reel, then drops one position down per spin
• Wild Multiplier: upgrades one sticky Wild with a multiplier up to x5 (random number)

There is no Bonus Buy feature, so you’ll have to rely on good ol’ luck to get to the Bonus Round.

Typically for Play'n GO slots, Dio - Killing the Dragon has an RTP of 96.2% or over. In this case, it’s 96.25%, right on point for highly volatile slots. It’s a pretty rewarding slot when the bonus runs hot, with a projected winning potential of 15,000x the bet.

If you’re into heavy metal and you’re a fan of Dio, you’ll love what this slot has to offer. It’s got 243 ways to win, Dio starring in a St. George-like role, and plenty of monsters to slay. Helping Dio be the bearer of bad news to all kinds of monsters has never felt better, and the slot has the specs to back it up.

It’s another fantastic tale by Play’n GO, and one well worth your time and money at our recommended new casinos online.
