You’d be forgiven if the online slot Zillard King immediately evokes a sense of monstrous adventure in you. Players get to embrace the darker side while unlocking sticky, stacked, increasing multiplier wilds by collecting a maximum of 90 Gold Coins — more about how this works below. 

 There aren’t many online slots like this one out there. Zillard King transports you into a world where the giant sea monster has left its habitat to wreck the city. 

Here’s a comprehensive review of the Zillard King online slot. 

Game Overview

Zillard King is a medium-volatility online slot machine game that plays out on 5×4 reels with 30 paylines. It also has an additional sixth reel that functions as a program meter where coins are stored when collected. Zillard King has a return to player (RTP) of 96% and offers you the chance to win up to 3800x your stake. 

How To Play

Online slot machines are generally easy to play, and Zillard King is no exception. Simply load the game and press the yellow circle with two blackish arrows on it in the lower-right corner of the screen. You’ll see when the game is activated. You can change the bet size on the right side of the screen. Zillard King also provides the option to increase the speed of gameplay. Alternatively, you can select the autoplay function. Don’t forget to check out the game’s paytable to see how much each symbol is worth and how many you need to land for a winning combination. 


In Zillard King, Red Tiger provides players with some stellar graphics. It kind of leans on Jurassic Park, with a giant lizard pulling itself out of the ocean on a mission of destruction. Visuals include dark, menacing clouds, cracking lightning, an approaching sea storm, and strong winds. It’s incredibly dramatic but fun to witness as you gear up to win thunderous payouts. You can see a city in the distant background, suggesting the people there are blissfully unaware of what’s lurking in the sea. The symbols on the reels include the four card suits (clubs, diamonds, hearts, and spades), which pay out 0.6–1.5x your bet for five of a kind, a helicopter, a Zillard wild, and Thunder wild.


The main objective of Zillard King is to collect gold coins to unlock the Zillard Wild upgrades. You’ll see gold coins randomly appearing on the bottom right-hand corner of any symbol on the same grid. If you land gold coins on the same spin as a Zillard wild symbol, they’re collected and will activate the Zillard Wild Progress Bar.

Bonuses and Jackpots

With the help of the gold coins, the Zillard Wild can bring some pretty neat rewards. In Zillard King’s slots bonus, the wild replaces any paying symbol to complete winning lines. As gold coins are collected on the screen, the Zillard Wild is upgraded:

  • Upgrade 1: 30 coins are collected, turning the Zillard wild into a full reel 1×4-size symbol.
  • Upgrade 2: 60 coins are collected, adding a random multiplier to the Zillard Wild.
  • Upgrade 3: 90 coins are collected, turning the Zillard Wild “sticky” — the wild symbol remains locked on the reels until it participates in one win, followed by a non-winning spin.

And that’s not all. During gameplay, when a Zillard wild symbol lands but there’s no win, there’s a chance that Zillard will roar to summon the Thunder wilds onto the game grid to guarantee a win. Players will receive between three and six Thunder Wilds if five reels are active or between three and nine if the sixth reel has been unlocked.
