Holy Diver slot game review

Holy Diver is the first slot in Big Time Gaming’s new and innovative Reel Adventure™ series, and it features elements from adventure video games. Tag along with a heroic knight in shining armor, and play across 3 different tier worlds with unique RTP’s and volatility. Choose whether to level up, or enter the free spins feature where you will benefit from MegaWays™ up to 586 971 paylines and a max win of 23 306x your stake.

Holy Diver RTP, variance & technical data

Holy Diver slot is packed with action and adventure, but first we thought it would be a good idea to reveal this game’s impressive technical data for you:

  • RTP: 96.39% - 96.54%
  • Volatility/Variance: Low, Medium & High
  • Layout: 6 reels and up to 7 rows
  • Paylines: Up to 586 971
  • Bonus features: Expanding Symbols, Free spins, Multipliers, Random Wilds, Substitution of winning symbols, Symbols collection (Energy), Reel Adventure™ and MegaWays™
  • Bets: 0.1 to 20
  • Max wins (coins): 17 042x (base game), 23 306x (free spins)

Holy Diver slot comes with 3 tiers of volatility across 3 different worlds, and that explains the difference in RTP also. The Return to Player will therefore change slightly across those levels, but the difference is not really that significant. Not so when it comes to volatility, cause here the difference is consequential and something you need to be aware of as you reach the different levels.

Holy Diver Review

Holy Diver is a very innovative and exciting game inspired by James Dio’s 1983 heavy metal megahit by the same title. This is the very first game in what is planned to be a series of Reel Adventure™ slots from Big Time Gaming. This series of slots will combine traditional video game features with a video slot, and Holy Diver is thus a pioneer game.

As you spin the reels, the animated knight below the reels is set on a heroic journey across 3 different worlds and levels. He’s driven forward by your spins, and will help your game by opening treasure chests he finds along the way. These chests contain different bonus feature and wilds that will boost your winnings for sure. As you and the heroic knight march into the unknown, massive riches lies ahead of you with up to 586 971 ways to win!

Holy Diver succeeds very well with fusing video game elements into the slot machine format. It’s fun to have a companion that follows you along the way, not least since he will benefit you ever so often with many different features. When you level up you can choose the free spins feature instead, and this is where the seriously big wins can happen - depending on your current level.

Holy Diver bonus features

As you lead the way for the animated knight below the reels on his epic Hero’s Journey, so he will help you by opening treasure chests that will positively impact your game 4 different ways:

  • Standard Symbol Bonus feature will pick a lower value symbol and make all instances of this symbol into a wild on the reels
  • Sword Bonus feature can turn up to 3 reels into stacked wilds with a multiplier that goes up to 7x. The multipliers can combine into a whopping 343x
  • Fireball Bonus feature adds up to 4 flaming wilds onto the reels. They then explode into adjacent wilds also
  • Gem Symbol Bonus feature will transform at least 1 gemstone symbol into a wild. As you increase in level these can come with 2x or 3x multipliers too.

Shield of Fortune

To level up you need to fill up the gemstone-meter with gemstones from the chests your heroic knight stumbles upon along the way. When all 4 gemstone positions are filled up, you can choose to either level up or activate the free spins feature.

Holy Diver free spins

If you choose the free spins feature, you will promptly get 10 free spins to play out. Gems landing on reel 2 to 5 will turn wild, and can also feature multipliers corresponding to your level (level 2 equals 2x and level 3 equals 3x).

During the free spins feature the knight will collect diamonds instead of opening treasure chests. For every 4 diamonds you collect, you get 1 extra free spin. If you manage to collect 5 diamonds you’ll be awarded with 8 free spins. Any new spin also increases the MegaWays paylines, and these can go as high as 586 789 ways to win.

Holy Diver jackpot (max win)

There is no progressive jackpot to be won here, but you can certainly win some massive payouts even so. In the base game you can win up to 17 042x your stake, while in free spins mode there is a max win of 23 306x your stake.

Holy Diver mobile & tablet

You can play Holy Diver slot across all devices, and that certainly includes mobile and tablet. This is a great game to bring along with you, and you will have tons of fun playing on the go. Of course, you can play on your Android devices or your iPad and iPhone, all up to you.

SlotCatalog verdict

With Holy Diver Big Time Gaming has invented a whole new way of playing slots, and it really adds to the experience to have a heroic helper by your side while you play. Of course, the MegaWays™ engine is always a fun feature, but the Reel Adventure™ takes it to a whole new level of innovation.

We also like that you get to choose whether to level up, or enter into the massive free spins feature. We suspect this will be the first of many successful games in BTG’s exciting new series.


  • Great Reel Adventure™ with helpful heroic knight
  • 3 different tier worlds and levels with unique volatility and RTP
  • Choose whether to level up or to enter free spins mode
  • Great bonus features and massive free spins feature
  • Win up to 23 306x your stake in free spins mode


  • Not all that easy to level up
  • Perhaps a bit complicated for some
