Zillard King Slot RTP, Details and Wager Limits

Reels/Paylines: 5 reels +30 paylines

Stakes Range: 10p to £20 per spin

RTP: 96%

Max Win: 3,800 x stake per spin

The Zillard King slot game is played on 5 reels with 30 fixed paylines. A 6th reel can be unlocked during the bonus feature. All symbols pay from left to right on adjacent reels beginning from reel 1.

Stakes start from just 20p and rise up to £20 per spin. Just below the reels, you’ll notice the total bet per spin. Simply use the + and – buttons on either side to change the bet to your desired amount. Autospins and turbo spins are also a possibility in most territories apart from the UK. You’ll also find both options below the reels.

The Zillard King RTP is a flat 96%, which is bang on the average for an online slot. Volatility here is set at medium to high, so big wins are certainly possible, although not as frequently as a slot with lower variance.

The maximum win is 3,800 x your stake. This is best achieved during the bonus feature due to the number of wilds that can land to potentially open up the 6th reel with multipliers added.

Theme – Treacherous waters and a chilling soundtrack

Theme: Reptile

High Value Symbol: Orb

Compatibility: Mobile, Tablet, Desktop


The theme here is clear – it’s all about reptiles and specifically a huge lizard. Essentially Godzilla with a different name. As you load the game, lightning strikes and there’s loud and dramatic audio as the reels appear in front of stormy seas. The intense audio adds to the excitement of the game overall, which is great for fans of slots like this.

You can liken the audio to other titles of a similar nature like Microgaming’s Jurassic World. These types of slots are very dramatic and great to play, especially when the bonus features get going.

On the reels, you’ll find the typical card suits as the low paying symbols. The more valuable ones include a compass, a gas mask, a helicopter, and a glowing orb. The orb is the most lucrative symbol, paying 2.5, 5, 15 or 30 x your stake for 3, 4, 5 or 6 in combination respectively.

There’s also a wild in the game that can transform into stacked wilds and multiplier wilds for potentially bigger wins. When the sticky lands and that 6th reel appears, that’s when the huge wins can appear.

Zillard King Mobile


You can get stuck into the Zillard King slot game whether you’re playing on a laptop, tablet or smartphone. The HD graphics are great on smaller screens, and the intense gameplay makes for a really fun experience on mobile.

Zillard King Bonus Features

It’s all about the wilds in the Zillard King slot game, with Thunder Wilds and Zillard Wild Upgrades the main 2 bonus features. The other is the Gold coins feature – collecting those will unlock the stacked wilds.

Let’s explain everything to help you understand the features fully.

Gold Coins feature

Gold coins can appear in the corner of any symbol on any spin. As long as there are wild upgrades to be had, coins will keep coming. If the coins land on the same spin as a Zillard Wild, they’re collected and get put into the Progress Bar to the right of the reels. There are 3 stages of wilds to unlock, which we’ll get onto shortly.

Once the gold coins have maxed out the Progress Bar, a 6th reel appears where only high paying symbols can land.

Thunder Wilds feature

When a wild lands on the reels in the Zillard King slot but no win occurs, it could roar to summon Thunder Wilds onto the reels, thus triggering a guaranteed win. Between 3 and 6 Thunder Wilds could drop when there are 5 reels in play, and between 3 and 9 could drop if the 6th reel is unlocked.

Zillard Wild feature


When gold coins land and are added to the Zillard Wild Progress Bar, there are 3 upgrades that can be unlocked. These are:

1st upgrade Turns the Zillard Wild into a stacked 1×4 symbol.
2nd upgrade Adds a random multiplier to the Zillard Wild
3rd upgrade Turns the Zillard Wild sticky, and it will stay in place on the reels until at least 1 win lands.

For each win, the sticky is a part of, the multiplier increases up to 20x. Everything is reset once a non-winning spin occurs after at least 1 win has already landed.

Max Win (3,800 x)


Yes ok, there may be a lack of features with the Zillard King slot, but the wilds can cause some exciting chaos on the reels if they’re all unlocked. Ignoring this slight negative, it’s a nice slot to play and the audio and graphics are great.

Although your best bet of landing the 3,800 x max win is during the bonus feature, it is possible for it to land during the base game, so the potential here isn’t too bad even if some consider it to be pretty low.

It certainly looks like a Godzilla rip off to avoid any copyright issues, but it’s no less fun to get stuck into. With multipliers up to 20x available along with numerous wilds and some intense action, overall it’s a game well worth considering.

Feel free to give our Zillard King demo a try first to see if you like it.

Staying with the theme, there are plenty of other great options to pick from that can offer different bonus features and bigger max win opportunities. Play’n GO’s Raging Rex 2 comes with 30,000 x max win potential, whereas another similar slot, Tyrant King Megaways from iSoftBet is even bigger with a max win set at 50,000 x your stake.

  • 3,800 x max win
