Zillard King Bonus Features 

After playing the game for quite some time, I only managed to find 3 bonus features in Zillard King, with the main highlights being Zillard Wilds and Thunder Wilds

Let’s look in more detail at how this slot operates:

Zillard Wilds:

Unleash the Wilds! is the game’s slogan, and that’s where most of its bonuses can be found. You accumulate gold coins that fill up the progress bar and reveal new wilds. The stacked wild, which occupies four spots on a single reel and raises your chances of a winning line, is the first and costs 30 coins.

The second upgrade will include a random multiplier and cost 60 coins. The third and final improvement is the sticky wild, which costs 90 coins and keeps your wild fixed on the reels until you create a winning combination. The sixth reel will likewise start spinning once all three upgrades have been unlocked.

Thunder Wilds:

Thunder wilds, which can appear when the Zillard wild is on the reels, but there isn’t a winning combination, are separate from these upgrades. The Zillard will release three to six thunder wilds with a powerful roar, ensuring a win.

Proggresive Jackpot:

Red Tiger Gaming slots provide various progressive jackpot types. One is given randomly after a single spin, while the other is the time jackpot, which must be given before a specific day and time.

Storyline,Graphics and Sound 

The description “dinosaur slot” for Zillard King might be a little misleading. Although the loading screen features a spectacular lightning-framed image of a dinosaur, you are not traveling back in time to the prehistoric era. 

This Zillard is kin to Godzilla, emerging from the sea to terrorize the city, much like Red Tiger’s Primate King had some King Kong-like traits. The reels start floating above a stormy sea with moving waves and a foreboding, dark sky filled with animated lightning. 

This universe becomes even more unique thanks to symbols like a gas mask and compass. Soundtrack gives a creepy and dramatic feel when you spin those reels

RTP and Variance 

The RTP  is a flat 96%, which is in line with what is typical for an online slot. Given that the volatility of this slot is set between medium, large winnings are achievable less frequently than in a machine with reduced variance.

3,500x your bet is the maximum win. Due to the number of wilds that can land and potentially open up the sixth reel with multipliers, this is best accomplished during the bonus feature.

Zillard King Gameplay and Bet Sizes

Set a time restriction and a session budget that allows you to play responsibly, no matter how much fun you’re having playing the game online.

Starting up in the online version of Red Tiger Gaming’s Zillard King couldn’t be simpler:

  • Pick from low, medium, or high risk. When you play for real money, the stakes can be adjusted to match your comfort level with risk.
  • Pick between a manual bet and an automatic one, with autoplay options.
  • To modify your wager per drop, use the minimum, maximum, plus, and minus buttons.
  • You may play with 30 lines, so pick your bet size and let the reels spin!
Zillard King Gameplay

The reels are arranged in a standard 5×4 grid with 30 paylines. You may spin the reels of the slot machine for as little as 0.2 to 20 credits every turn.
