If you’re a fan of Print Studios and Relax Gaming slots, you know the developer creates some of the most engaging titles with the most unique themes. Such is Holy Hand Grenade, a Medieval-themed slot depicting times when the weirdest and most unconventional things were happening, as you'll soon learn.

When it comes to layout, the slot comes with a 5x4 grid in the base and a 6x5 grid in the Bonus Round, delivering 25 to 52 paylines for you to land winning combos on. It is highly volatile with a varying RTP, depending on the Bonus Buy options, and offers feature-loaded gameplay. If you're ready to explore Medieval times, come join us on the journey.

The reels are set upon the sturdy stone castle’s wall in the base game, and you enter the castle later on in the bonus round, where the action with explosions takes place. You can see that the game is set in a calm small town, as there’s a wooden fence on the sides of the reels, a fire about to burn down, and the woods way back in the backdrop.

On the reels themselves, you see all kinds of symbols, and their values can be found by pressing the three-bar button in the bottom right corner. You'll see that the playing card suits, presented in Medieval style, are the low-pays, followed by the candles, bag, medieval man and woman, and the bishop, delivering 1x to 20x the stake for the top combo in the base game, and 2x to 50x the stake in the Bonus Round. 

Moving a bit to the left, you’ll see the Autoplay button and, moving up, the big Play button. The Bet Configuration field is above it, whereby by pressing the < and > buttons, you can decrease or increase your bet from $0.10 to $60 per spin. Moving further up, you see the Feature Bet button, where for 50% extra, you will get more Scatters on the grid thanks to the Scatter Boost option, and for 95x the stake, you can get access to Free Spins. With the Scatter Boost on, the max bet goes up to $60. You'll see the Balance display in the left corner of the screen below the reels. 

As with all free online slots nowadays, Holy Hand Grenade is a fully mobile-optimized online slot, which can be played via any mobile device, be it a smartphone or a tablet. What’s more, to enjoy the most seamless Holy Hand Grenade play, you can actually play it in both portrait and landscape modes. That means that you’ll be able to take it with you and play it whenever and however you want. 

As you load Holy Hand Grenade, you will see that between the reels, there are some small markers, either blank or displaying a number, called SuperSpinners. These are active both in the base game and the Bonus Round. 

When displaying a number, and you manage to land a win on a payline that passes through the SuperSpinner, your win is multiplied by its number. If the winning payline passes through more than one SuperSpinner, they will apply their Multiplier values to the win each, in succession.

The most interesting feature in the slot is the Holy Hand Grenade Feature. When the same named symbol hits, after win evaluations are made, it will explode and, at random, transform a number of symbols adjacent to each other into the same random symbol. After the transformation, new win evaluations will be made.

Land 3, 4, or 5 Goat Scatters and you'll trigger 7, 9, or 11 Free Spins, respectively. Here, you have 52 paylines to land winning combos on, plus the SuperSpinners are active, so you can only imagine the Multipliers!

During the Bonus Round, when the Holy Hand Grenade Symbol hits the reels, it will mark its position with a flaming frame that lasts until the bonus ends. If it lands on an already framed position, another one will hit and again and again, causing bigger and bigger explosions. As if that wasn’t enough, with each Holy Hand Grenade symbol, you get 2 extra Free Spins added to the total.

We said that the RTP in the slot Holy Hand Grenade varies. The regular is 96.45%, but if you play the game with the Scatter Boost on, it goes up to 96.64%. If you use the Bonus Buy option, it will increase up to an amazing 96.82%! The slot is highly volatile, 4.5 out of 5, and it can deliver up to 20,000x the stake. 

Since the most you could play the game with is $60, with the Scatter Boost on, and the max payout potential is 20,000x the stake, the max payout you could scoop playing Holy Hand Grenade would be $1.8 million. This is quite a payout for such a seemingly straightforward slot.

Holy Hand Grenade is certainly a slot that deserves a shot. It offers a common theme, sure, but the humor in it and the feature-loaded gameplay definitely give it charm. The features are engaging and rewarding, and if you play it for the max bet, you could grab up to $1.8 million playing it. That’s a significant payout potential, one that would certainly intrigue high-rollers. So, if one, join Relax Gaming-powered casino sites, and before you load Holy Hand Grenade, get a bonus and go straight to the lobby to find the game and give it a try right away.
