Ronnie James Dio is one of the most influential rockers of the last half-century. Known as “Dio”, the American singer has fronted numerous bands (including Black Sabbath) and also made a name for himself with a solo career. He is even thought to have popularized the famous “devil horns” hand gesture.

The legacy of Dio is celebrated in the Dio: Killing the Dragon slot from Play’n Go. It’s a 243-payline slot that includes music from the man himself, as well as imagery inspired by his songs, artwork, and videos.

Dio: Killing the Dragon Game Features

The Dio: Killing the Dragon game begins with an epic intro that features a fire-breathing dragon, Ronnie James Dio on a throne, and a monstrous riff. Welcome to the world of Dio as crafted by Play’n Go—it only gets better from here.

The game features a variety of demonic and fantasy-themed symbols, including a Wolf Wild, Dragon, and a Sword-Wielding Dio. As expected, there’s also a Dio playlist, including Don’t Talk to Strangers, We Rock, and Evil Eyes.

The Wild is the biggest symbol on these 243 pay lines, followed by Dio. But these symbols pale in comparison to the features, and there are several of these to look out for.

Lock Up The Wolves activates when a Wild lands in the first reel. It becomes trapped in a cage while the reels respin and another cage is added to the second reel. If a Wild appears on the second reel, the process repeats, and it can continue in this manner until there are Wilds on all of the reels.

This feature can trigger during all base game spins. It is absent during the Free Spins, which are unlocked via the Bonus symbol. You need three or more of these and can get between 6 and 12 Free Spins when they land.

When Wilds appear in the middle reels during the Free Spins, they lock in place. Essentially, the reel 1 cage of the Lock Up The Wolves feature shifts to reels 2, 3, and 4 during the Free Spins, greatly boosting the payout potential.

The unique Crystal Ball symbol can appear during this feature. If it lands on the final reel, two more Free Spins are added to the total, and one of the following triggers:

  • Fallen Angel: A Wild symbol is added to the top of the reels. It remains sticky, but after every spin, it drops one place and continues until it falls off the bottom of the reel.
  • Symbol Upgrade: The lowest-value main symbol is converted to a Dio symbol, which offers some of the biggest payouts in the game.
  • Wild Multiplier: A Wild symbol is given an improved multiplier of between 1x and 5x.
