Holy Diver Megaways (Big Time Gaming) Slot Review

Holy Diver Megaways: Slot Overview 

Holy Diver Megaways by Big Time Gaming is no ordinary slot. While most Megaways games follow a familiar path, Holy Diver diverges (pun intended) with its innovative Reel Adventure™ mechanic, offering a hybrid between video slot and role-playing game. Set against the backdrop of a fantastical world inspired by medieval quests and infused with heavy metal attitude, this slot draws its name from the 1983 Ronnie James Dio anthem “Holy Diver.” 

Built on a 6-reel Megaways engine, this slot offers between 2 to 7 symbols per reel, yielding up to 117,649 win ways in the base game—and up to 586,971 ways to win in the bonus round. With a 96.39% RTP, high volatility, and 20,000x max win potential, Holy Diver stands out not just for its gameplay structure, but also for its compelling mix of audiovisual elements, strategic depth, and replayability.

Design and Graphics 

Holy Diver blends medieval fantasy with BTG’s signature polished visuals. The background is a striking mix of bright blue skies and gothic stone ruins, with subtle details such as ruined statues and drifting clouds giving the setting a quiet sense of lore. Below the reels, an animated knight—the game’s protagonist—marches along a path, coming across treasure chests that activate bonus features every few spins. The reel set itself is bold and ornate, framed in metallic gold with richly colored symbols. These include low-paying 9 to A royals and four gems—green, blue, red, and purple, the latter being the most valuable with payouts of up to 15x for six of a kind. Wilds, bonus features, and multiplier-enhanced symbols light up with animations that give each spin a dynamic feel. 

Visually, it resembles a blend of BTG’s earlier hit Dragon Born and a classic fantasy RPG, offering an immersive visual experience that’s uniquely different from standard Megaways layouts.

Gameplay Mechanics 

At its core, Holy Diver is built on the Megaways engine, but the real gameplay differentiator is the Reel Adventure™ system. This introduces an RPG-like structure where the animated knight journeys across the screen, opening treasure chests every 1 to 5 spins, triggering one of four random reel modifiers: 

Reel Modifiers 

Standard Symbol Bonus: One low-value symbol is converted into a wild. 

Sword Bonus: Adds up to 3 wild reels with multipliers up to x7. 

Fireball Bonus: Launches up to 4 wilds onto the reels. 

Gem Symbol Bonus: Transforms collected gems into wilds that may carry x2 or x3 multipliers. 

These modifiers ensure that even the base game feels exciting and rewarding. The knight’s progress gives a sense of anticipation every few spins, encouraging long sessions. 

Gem Collection and Leveling System 

Rather than using traditional scatters, Holy Diver uses a gem collection system. Players must collect 4 gems of different colors from treasure chests to unlock the free spins feature. But here’s the twist—you can decline the free spins and continue collecting gems to level up. 

Level 1: Free spins with x1 wild multipliers 

Level 2: Optional entry or continue to Level 3 with x2 multipliers 

Level 3: Final level—must enter free spins with x3 multipliers 

This system allows players to choose their volatility, a rare and appreciated form of strategic agency in slots.

Sound and Music 

As the name implies, Holy Diver leans heavily into its heavy metal roots. The soundtrack features powerful guitar riffs that elevate the energy, especially during bonus features and big wins. It’s a true homage to Dio’s iconic track and fits the heroic-fantasy-meets-metal vibe perfectly. 

The game features ambient background music during regular spins, which ramps up dramatically when treasure chests are opened or wild modifiers kick in. Sword slashes, fiery bursts, and mystical gem transformations all have rich, satisfying sound effects. 

And when the Free Spins round triggers, expect a full-on metal soundtrack that’ll make any spin feel like a boss fight in an RPG.

Bonus Features 

Free Spins with Gem Wild Multipliers 

Triggering free spins awards 10 spins, and each collected diamond on reels 2 to 5 becomes a wild symbol with a level-based multiplier: Level 1: x1 wilds 

Level 2: x2 wilds 

Level 3: x3 wilds 

As the knight continues his journey during free spins, new diamonds can be collected. Every 4 diamonds awards +1 extra spin, and reel 6 is unlocked, allowing win ways to increase up to a massive 586,971 Megaways. 

Progressive Re-Triggers 

Each time you collect enough diamonds during free spins, the number of available win ways increases and you earn +8 extra spins, meaning re-triggers are not only rewarding but also expand the potential of the grid. 

Decision-Based Progression 

What makes this bonus round so unique is that players get to choose their risk level by deciding whether to play free spins immediately or level up. It’s rare in slot design to give such a level of player agency, and it significantly improves replayability.

Betting Options and Payouts 

Holy Diver offers a wide betting range to accommodate casual players and high rollers alike. You can stake anywhere from €0.10 to €20 per spin. 

RTP: 96.39% – very fair for a high volatility slot 

Max Win: 20,000x your stake 

Volatility: High – although less brutal than BTG’s more punishing games like Lil’ Devil or Wild Flower 

Symbol payouts, especially for the purple gem and wild combinations, can be substantial. The inclusion of multiple reel modifiers and progressive bonuses helps balance the dry spells with moments of high-energy payoff.

Conclusion 

Holy Diver Megaways is more than just another Megaways slot—it’s a bold step in a new direction for Big Time Gaming. With its Reel Adventure™ mechanic, treasure chest bonuses, gem-based progression system, and strategic free spins structure, it combines the best of slot gameplay and RPG elements into one deeply engaging package. 

The game’s pacing and decision-making design allow players to feel more involved than in most slots. You can tailor your experience—go for safe rewards or push for riskier levels with better multipliers and higher potential. 

Graphically rich, sonically intense, and mechanically innovative, Holy Diver Megaways sets itself apart. It’s a love letter to fantasy fans, RPG gamers, and metalheads alike—and even if you’re none of those, the dynamic gameplay and up to 586,971 win ways are reason enough to dive in. 

Whether you spin it for the massive win potential or just to enjoy Dio’s legendary influence, Holy Diver Megaways is a slot experience that shreds hard and plays even harder.
