Unleash the mythical beast in the Zillard King online slot

Unleash the mythical beast in the Zillard King online slot

Welcome to the Zillard King Online Slot

The Zillard King video slot will remind you of the Godzilla movies. But the Zillard King is different from Godzilla because he has the power of thunder, while Godzilla is shown shooting a nuclear beam in the latest movie. Still, we can’t deny that he looks similar to Godzilla, and this is an excellent idea for a slot.

This slot revolves around the Zillard Wild upgrades, and you can upgrade it by collecting Gold Coins in the Progress Bar. The first upgrade will transform it into a Stacked Wild, and then you will be able to go for more powerful upgrades like a random Win Multiplier.

The most exciting part is that you can unlock the sixth reel after you unlock all 3 upgrades for the wild symbol. Thunder Wilds are also there to help you transform a losing spin into a winning spin.

There is no doubt that playing this slot will be fun simply because it rewards you for playing longer and features a super fun theme. Red Tiger has been successful in creating a dark and exciting atmosphere in this slot. The look and feel of this slot are pretty good, and the features don’t disappoint either.

In short, this slot looks promising, and we are excited to explore it in detail.


Mythical Monster Theme and High-Quality Graphics

Theme and Design

The theme of this slot is a work of art, and we like the menacing look of this slot. It feels like the giant lizard monster is about to head to the city from the sea and destroy it. In the background, you can see cloudy skies, a violent sea, a city in the distance, and several small details like an old ship.

Even the background music has been designed to build tension and move in sync with the gameplay. So you will be fully engaged by the gameplay of this slot.


The high-paying symbols are a glowing egg, helicopter, gas mask and backpack, and compass. The premium symbols will pay you 6x to 30x of your bet for landing six-of-a-kind winning combinations. On the other hand, the low-paying symbols are the suits of cards. They will pay you 0.6x to 1.5x of your stake for landing a six-of-a-kind winning combination.

The Zillard King serves as the Wild symbol, which can be upgraded 3 times. After the third upgrade, you can unlock the sixth reel.

Mighty Bonus Features

The gameplay of this slot revolve around the Zillard Wild upgrades and collecting Gold Coins. Let us start exploring the Bonus Features now.

Gold Coins and Progress Bar

The Gold Coins land attached to other symbols, and they will continue to land until all Zillard Wild upgrades are done. The Gold Coins are collected in the Progress Meter when they land with a Zillard Wild symbol on the reels.

Collecting 30 coins will unlock the first upgrade, and collecting 60 coins will unlock the second upgrade. The third and final upgrade will be unlocked after you collect 90 Gold Coins.

After all upgrades are complete, the Zillard Wild Progress Bar turns into the 6th reel. Only high-paying symbols will show up on the 6th reel.

Thunder Wilds Feature

If the Zillard Wild is on the reels and no win occurs, he can roar to summon Thunder Wilds and give you a guaranteed win. You can get 3 to 6 Thunder Wilds if the 6th reel hasn’t been unlocked. If you have unlocked the 6th reel, you will get 3 to 9 Thunder Wilds.

Zillard Wild Upgrade Feature

The Zillard Wild symbols can be upgraded to become more powerful. Following are the upgrades that can be unlocked by collecting coins.

  • Upgrade 1: The Zillard Wilds transform into Stacked Wilds.
  • Upgrade 2: Random Multipliers will be added to the Stacked Zillard Wilds.
  • Upgrade 3: It will make the Zillard Wild sticky, and the Sticky Wilds will remain sticky until you get a win.

The random Multiplier can go up to 20x because it will increase after each consecutive win it participates in. When you stop getting wins, the Zillard Wild will disappear and reset.

Is Zillard King Slot Worth it?

The Zillard King slot may not look that impressive initially, but you will love it if you play it for a little longer. Red Tiger Gaming is a great slot developer, and they have repeatedly proved it by releasing free slots like this one.

The standard Wild symbol can be upgraded several times, and it will take you closer to the maximum win of 3,500x of your bet. You will collect Gold Coins, and the Zillard Wild Progress Bar will be filled with them. After you unlock all 3 upgrades, you will find it very easy to score big wins. The only issue is that it will take a while to get there.

There are no bonus spins or Free Spins in this slot, but it is still very impressive. The fact is that most slots without Free Spins fail to deliver a very rewarding experience, so we have to commend this slot for it.
