Holy Diver Slot

Holy Diver video slot heralds Big Time Gaming’s next phase of innovation as they introduce their new Reel Adventure™ mechanic to their already well-established Megaways™ engine. The Reel Adventure™ Mechanic only comes in to play during the free spin round where you can trigger up to an astonishing 586,789 ways to win.

With a medieval theme, Holy Diver (named after the 1983 album and single by American heavy metal band Dio) is a medium to high volatility slot with 6 reels and between 2-7 symbols per reel and an RTP of 96.39% (up to 96.54% in the bonus round).

It is said that this game was being developed around the same time as Bonanza. The game benefits from a multi-level free spins round with multiplying wilds and you can play from €0.10 up to €10 per spin.

Design and Symbols

BTG - Holy Diver. Image showing reels

Visually, Holy Diver is not dissimilar to one of BTG’s classic Megaways™ slots from 2016, Dragon Born, especially the square gold framed game board. The game board sits centre screen on top of a carved stone structure which resembles the top of a gravestone. Their background reveals a blue sky leading up to some ominous looking rains clouds above.

To the left of the game board is a gold shield – the Shield of Fortune - with spaces to hold four different coloured gemstones, and to the right of the game board sit the controls.

The low-value symbols are the standard 9 – A royals with the higher value symbols represented by Green, Blue, Red, and Purple gems. The highest value is the Purple gem which pays 15x the bet size for 6 across a pay line.

Below the game board, there is an additional screen approximately 2 symbols high which runs the full length of the board in which an animated Knight is running along a path kicking open treasure chests (more of which a little later).

Special Features in Holy Diver

In the base game, you can activate four different reel modifiers, and Holy Diver also has a great free spins round which comes with three different levels where each additional level adds wild multipliers to exponentially increase your potential wins. The free spin round is also where you’ll be given the chance to increase the ways to win up to a potential 586,789.

Treasure Chest Reel Modifiers

All the while you are playing the game the animated Knight is running along his path where he will encounter treasure chests (approximately once every 4 or 5 spins) which he will proceed to kick open. The open chests will then reveal one of four reel modifiers, which are:

  • Standard Symbol Bonus – One of the lower value royal values is picked at random and every occurrence of that symbol on the reels will transform into a wild.
  • Sword Bonus – Between 1 and 3 reels will turn fully wild with multipliers of between 1x and 7x. Land all 3 with a 7x multiplier and the total multiplier will be 343x as the multipliers combine.
  • Fireball Bonus – Fires up to four burning wilds onto the reels
  • Gem Symbol Bonus – The chest may reveal between 1 and 4 gem colours which will not only transform into wilds with between 1x and 3x multiplier but will also fill the Shield of Fortune which will ultimately trigger the bonus round

Free Spins

Complete the Shield of Fortune by collecting all 4 coloured gems from the treasure chests and you will be awarded 10 free spins. During free spins, which take place against a moonlit backdrop next to the sea, any gems which land on reels 2-5 will turn wild.

Also, the Knight will still be charging across the path below the game board but instead of coming across treasure chests to open he will be vanquishing foes with his sword.

Occasionally one of these cloaked enemies will reveal a diamond after being slain.

  • For the first 4 diamonds revealed you will receive an additional free spin,
  • The 5th diamond will retrigger the feature with 8 additional free spins.

Furthermore, once you retrigger the bonus you will open up additional ways to win as after a spin a random number of symbols, once used, will disappear and be replaced with new symbols, thus creating extra ways to win up to a maximum of 586,789. Throughout the free spin round the song “Holy Diver” will play in the background.

Levelling Up free spins

When you are awarded 10 free spins after filling the Shield of Fortune you can take the opportunity to decline the bonus round but instead move up a level and go back to the base game.

  • At the second level, you will play with an upgraded 2x wild multiplier.
  • Trigger the free spins again and you can play your spins with this 2x multiplier.
  • Decline and progress to the third and final level where you’ll play with a 3x wild multiplier. Trigger the free spins this time and you’ll automatically start your 10 free spins.

While levelling up will certainly increase your potential for a big win (and it also very marginally increases your overall RTP), be prepared to increase your volatility also as the instances of the Knight revealing gems from the treasure chests reduce dramatically with each level up.

While this may seem harsh, the potential wins are much higher when you consider that the multipliers come into effect, and whereas level one only offers a total 1x multiplier, hit wilds on reels 2-5 on level 3 and your win will be multiplied by 81x (3x3x3x3). If you manage to retrigger the bonus on level 3 and release up to 586,789 ways to win with 3x wild multipliers then you really can land a monster win.

Our Thoughts on Holy Diver

Well, Big Time Gaming have done it again, they have engineered another truly innovative slot mechanic with Reel Adventure™ which creates even more action and makes Holy Diver even more immersive than many of its Megaways™ predecessors.

Exchanging scatter symbols for the Knight animation is a nice touch, and it is certainly nice to land a free spin round (at the base level) fairly regularly. Of course, this comes at a price also, with the biggest 6 in a row win being just 15x bet size compared to the higher volatility Megaways™ slots which pay around the 50x mark.

This isn’t necessarily a bad thing though as this will broaden the game’s appeal to those players who don’t particularly want a high variance affair and this game at the base level seems to be at the low side of medium variance.

The beauty of Holy Diver, however, is that the ability to level up immediately increases the volatility for those who don’t mind grinding it out in their quest for that elusive big win.

Of course the fact that there are so many more ways to win doesn’t mean you will win more often, at the end of the day the RTP is the same is pretty much every other game released these days – but when it comes to action and entertainment, you just can’t beat a Megaways™ slot these days.

So, apart from the mysterious choice of name (perhaps the designer just loves that track?), we love everything about this new game from BTG.
