Reel Adventure Feature & Fireball Bonus

The Reel Adventure feature can be seen at this base of the screen, where you will see a brave knight who progresses along a path full of treasure chests along the way.

The knight gives the treasure chests a hard kick that will open them to reveal prizes within in the form of four reel modifiers. They apply to reels 2, 3, 4, and 5. The initial modifier is the Standard Symbol Bonus.

Low-value card royals are selected, and they will all land in full view right onto the inner reels, which will subsequently turn into wild symbols.

The Sword Bonus round is the second option, and three reels may turn into Wild Swords each with multipliers of between 1x and 7x your wager. If all three Wilds reveal 7x multipliers, your whole layout could shoot up to a high 343x your trigger bet.

The Fireball Bonus is the third modifier, and it can gift you up to four Wilds, maximum one per reel. The Exploding Wilds can affect the adjacent reels also turning them into Wilds.

The fourth and last option of the Gem Symbol Bonus, whereby a gem will appear from within a chest. If you match gem icons on the inner reels, you also get multipliers of 1x to 3x your wager, and all the Gems that are revealed are added to your Shield Of Fortune Collector.

When you pick Gems, you go to the next Free Spins level, and all four Gems takes you right through them all. Each level is bet sensitive, rising with each level.

The 4 Magic Gemstones

Holy Diver uses tried and tested symbols and a set of originally crafted ones. You get the poker card values from the number nine, up to the Ace.

You will also see green, blue, red, and purple gemstone symbols, which only apiece upon the spinning reels when the Reel Adventure modifiers are activated. There is no Scatter symbol, and the Free Spins can be activated when you collect at least four Gemstones.

You can expect a heavy metal-themed that really does justice to the classic hard rock song by Dio. The overall design is serene and beautifully atmospheric serving up an epic, mediaeval slot adventure with all the significant elements typically found in premium online video slot games.

During the free spins round, the maximum payout can scale up to 586,789 ways you can win a payout. The game allows you to choose your own preference of volatility for your session.

You can either use Level One Free Spins, which provides additional bonus games, however, with more modest payouts. The other option is to progress to the higher levels, with higher stakes, fewer bonus rounds with a much higher potential for a high payout.
