How To Play Holy Diver

There’s only one way to get set for your Holy Diver slot quest, which is to set your bet size by using the “+” and “–” buttons on the right-hand side of the screen. The least you can bet is $0.10, and the most is $20. To inform your decision, read up on the game rules and study the paytable via the Menu button just below. When your mind’s made up, press the Spin button to initiate a spin. Alternatively, up to 100 autospins are available for hands-free play, with selectable loss and win limits.

Holy Diver Game Features

The big news about the Holy Diver slot is the Reel Adventure feature. Below the 6 Megaways reels, there’s an animated display like a portal showing the adventures of a medieval knight. When you spin, the knight walks or runs toward a series of chests, which he kicks open to reveal various reel modifiers:

  • Standard symbol bonus: Randomly chooses a low-value symbol to convert into a wild.
  • Sword bonus: Turns up to 3 reels fully wild with a multiplier up to 7x. If all 3 reels have a 7x multiplier, it works out at 343x.
  • Fireball bonus: Shoots up to four fiery wilds onto the reels.
  • Gem symbol bonus: Awards one or more gems and turns them into wilds, which apply 2x or 3x multipliers on higher bonus levels.

Gems are collected to the Shield of Fortune on the left of the reels. Collect all four color gems to trigger the bonus feature.

Holy Diver Bonuses and Jackpots

So you’ve triggered the Free Spins bonus by collecting all four gems. But first, you have to make a decision. Will you play the bonus immediately, or will you choose to level up instead? This means you forgo the bonus for the moment in exchange for increased multipliers and more ways to win the next time you activate the feature. On Level 2, you get 2x multipliers, while Level 3 comes with 3x multipliers. You can’t level up beyond Level 3.

Regardless of what level you’re on, activating the bonus awards 10 free spins as Dio’s song “Holy Diver” kicks in and the gems on reels 2–5 turn into wilds.

The panel below the reels, where the knight battles mystical enemies, can reveal diamonds. The first four award an additional spin each, and the fifth diamond retriggers the bonus with eight additional free spins while increasing the number of win ways up to a maximum of 586,000.

How To Win Holy Diver

Winning at the Holy Diver slot game isn’t complicated at all. Simply land three or more like pay symbols on adjacent reels (starting with reel 1) to form combinations that pay out according to the paytable. Each of the 6 Megaways reels can have up to seven positions on any given spin, generating up to 117,649 ways in the base game. 

To maximize your win potential, you’ll want to fill the Shield of Fortune with gems and trigger the Free Spins bonus. If you have the discipline to wait until you’ve progressed to Level 3, you’ll get a bonus round with gems that become 3x wild multipliers, which unlocks the maximum win potential of 23,306x the bet. Just beware — high volatility means it can take some time to fill the Shield, so keep an eye on your bankroll.

Holy Diver Graphics and Design

From a production point of view, the Holy Diver slot game is a knockout. The reels are set on a rocky outcrop like a massive magic mirror against a cloudy sky, while on a portal just below, the heroic knight pursues his quest through a changing landscape of fields of trees. The base game is serene, with quiet background music as the knight kicks open the Chests of Fortune. When Free Spins kicks in, the knight engages in an epic battle as Dio’s “Holy Diver” song accompanies the action with thrashing heavy metal.

Holy Diver Symbols

The symbol set populating the paytable is quite limited, consisting of low-value card royals and four different colored gems that pay up to 15x the bet for six of a kind. This doesn’t represent massive value, but with so many ways to win in play, it doesn’t really matter. The real action is taking place on the Reel Adventure portal below the reels, as the knight opens Chests of Fortune containing reel modifiers and defeats mysterious adversaries to reveal extra spins.
