Holy Hand Grenade (Print Studios) Slot Review

Holy Hand Grenade: Slot Overview 

Released on March 30, 2023, Holy Hand Grenade is a wildly imaginative online slot by Print Studios that draws inspiration from the iconic comedy of Monty Python and the Holy Grail. Taking its name from the “Holy Hand Grenade of Antioch” as humorously referenced in the film, this slot blends absurd medieval satire with a technically complex and deeply explosive game structure. If you’re seeking a slot with charm, challenge, and a healthy dose of chaos, this one delivers in spades. 

The action unfolds across a 5-reel, 4-row base grid with 26 paylines, expanding to a 6×5 setup with 52 lines in the free spins round. The slot plays with high volatility (4.5/5), supports bets from €0.10 to €90, and comes packed with SuperSpinners, explosive modifiers, and one of the most unique bonus mechanics Print has ever devised. The maximum win caps at 20,000x your stake, and though the free spins frequency sits at 1 in 288, its potential for chain reactions and snowballing effects is worth the wait. 

Let’s explore this holy (and wholly mad) slot experience in detail.

Design and Graphics 

Holy Hand Grenade takes players to a whimsical medieval world wrapped in stone towers, stained-glass motifs, and a backdrop that wouldn’t feel out of place in a Monty Python skit. The visuals are intentionally theatrical and exaggerated—leaning into parody rather than historical authenticity.The reels are framed in stone, giving the impression of a cathedral wall. Symbols include royal playing card suits, candles, bags of gold, and caricatured characters like a noblewoman, a monk, and a bishop, each drawn in an exaggerated, animated art style. The Holy Hand Grenade scatter is a golden orb adorned with a goat’s face—a hilarious reference that sets the tone. 

When the game shifts into free spins, the entire screen erupts into flames and mayhem. The introduction of a sixth reel and dynamic explosion effects gives the bonus round a sense of mounting, ridiculous grandeur. It’s pure satire and spectacle—precisely the mood the developers intended.

Gameplay Mechanics 

Beneath the light-hearted exterior lies a surprisingly strategic and volatile setup. 

In the base game, players spin a 5×4 grid across 26 paylines. 

Winning combinations require 3+ adjacent symbols from the leftmost reel. 

The lack of a wild symbol is offset by SuperSpinners and the Holy Hand Grenade explosion feature. 

Paylines increase during the bonus round: 

Free spins play out on a 6×5 grid with 52 paylines. 

The reel expansion increases symbol density, boosting both win potential and visual impact. 

At its heart, Holy Hand Grenade relies on multiplier chain reactions, symbol transformations, and an evolving bonus system that encourages buildup and explosive payoff.

Sound and Music 

Print Studios has crafted an audio package that perfectly complements the game’s medieval comedy theme. The background music blends Gregorian-style chants, goat bleats, and dramatic organ chords, all arranged in a playful, slightly mocking tone. It’s the kind of soundscape that feels straight out of a Monty Python scene—reverent, ridiculous, and fully aware of its own theatricality. 

Key sound effects highlight each major action: 

SuperSpinners click and chime as they activate. 

The Holy Hand Grenade lands with a booming “Hallelujah” and explodes in a cacophony of goat bleats and reverb-heavy blasts. 

Free spins are accompanied by a grand, swelling soundtrack that makes the chaos feel like a medieval opera of destruction. 

This is one of Print’s most intentionally comedic sound designs, enhancing every feature with tongue-in-cheek grandeur.

Bonus Features 

SuperSpinners

Positioned between the reels, SuperSpinners are Print Studios’ signature mechanic:Some display a number multiplier, while others remain blank. 

If a win line passes through one or more numbered SuperSpinners, their values multiply the win. 

Multiple SuperSpinners on a win line stack their multipliers sequentially, leading to some impressive chain effects. 

These become especially impactful during the bonus round, where more symbols and additional paylines increase the chances of hitting enhanced lines. 

Holy Hand Grenade Feature

The titular Holy Hand Grenade doesn’t just sit around—it explodes: 

When it hits, it waits for win evaluations, then detonates. 

This explosion transforms a random number of adjacent symbols into a single random symbol, potentially forming or extending new wins. 

This action can cascade into more explosions if a new grenade is triggered by the win. 

This feature brings a chaotic twist, allowing one scatter to reset the game board in your favor. It’s wild, unpredictable, and wholly satisfying when it lands. 

Free Spins

Triggered by 3, 4, or 5 goat-faced scatters, awarding 7, 9, or 11 free spins respectively. Once active: 

The grid expands to 6 reels and 5 rows. 

52 paylines come into play. 

Grenades now leave behind “framed” positions where they land. 

If a new grenade hits a framed space, a bigger explosion occurs, affecting a wider area. 

Every grenade explosion in free spins also awards +2 spins, creating potential for a long, chain-reaction bonus. 

This snowball mechanic can lead to a chaotic cascade of explosions, symbol matches, SuperSpinner boosts, and retriggers. It’s explosive in every sense and where the game’s 20,000x max win becomes most likely.

Betting Options and Payouts 

Holy Hand Grenade accommodates a wide range of players with a minimum bet of €0.10 and a maximum of €90 per spin. The game’s mathematical model is tuned for high risk and high reward: 

RTP: 

Regular play: 96.45% 

With Scatter Boost: 96.64% 

Bonus Buy (95x): 96.82% 

Free Spins Frequency: 1 in 288 spins 

Volatility: High (4.5/5) 

Max Win: 20,000x 

Max Win Probability: 1 in 58,823,529 spins 

This is a game built for players who don’t mind variance, as free spins and huge wins can be spaced far apart. That said, the Scatter Boost (50% extra cost) increases the chances of triggering the bonus significantly and might appeal to more risk-tolerant players.

Conclusion 

Holy Hand Grenade is the kind of slot that only Print Studios could have pulled off: absurd, theatrical, hilarious—and yet, hiding deeply polished mechanics beneath the humor. From exploding goats to cathedral-style reels and SuperSpinner boosts, every part of the design reinforces a central theme of controlled chaos. 

For players who love escalating bonus rounds, unpredictable features, and high volatility, this game delivers in spectacular style. While it may not be as accessible as some of Print’s more “hygge” releases (like Pine of Plinko), those who stick with it will find a bonus round brimming with potential, humor, and replay value. 

Ultimately, Holy Hand Grenade continues Print Studios’ trend of taking bold creative risks. It’s one of the few games where a combination of goat bleats, chain explosions, and Monty Python-inspired absurdity doesn’t just work—it excels.
