Zillard King Slot Review
Zillard King holds its best self hostage to a coin count. Play the opening stretch and you’re funding a wild that hasn’t learned its tricks yet, on a paytable that won’t carry the wait; out past the icy frame, on that storm-lit sea, the monster you came for is still under the water.
The waiting is the point. Red Tiger have made patience the entry fee, with the rewards back-loaded enough that early spins exist mostly to fund later ones. It runs on a 5×4 grid at 95.69% RTP, with a 3,500x maximum win and stakes from 0.10 to 50 per spin. The Megaways remake took the same storm to a bigger grid in 2026 and kept the patient core, and Primate King roams similar giant-creature ground. The original’s appeal is quieter: a storm that hasn’t broken yet.
Symbols and Pays
Eight paying symbols fill the reels: four picture symbols and four royals. The pays run from three of a kind up to six, and a 5×4 grid can’t line up six of anything, so those top prizes wait on the sixth reel coming into play.
The Zillard Wild substitutes for all paying symbols, and everything else in the game is arranged around it. It’s a scatter as well as a wild, which matters for the coin collection described below.
The paytable’s printed values for three, four, five and six of a kind are:
- Teal Egg: 2.5, 5, 15, 30
- Helicopter: 1.5, 3, 10, 20
- Soldier: 1, 2, 6, 12
- Amulet: 0.5, 1, 3, 6
- Spade: 0.2, 0.5, 1.5
- Heart: 0.2, 0.4, 1.2
- Diamond: 0.1, 0.3, 1
- Clover: 0.1, 0.2, 0.6
The gaps between tiers tell the story of the paytable. A full line of the teal egg pays thirty times more than a full line of the amulet, and the royals sit in a narrow band at the bottom, all of them capped below the amulet’s three-of-a-kind. Five clovers returns less than a single soldier pair-step up the ladder.
The four royals are almost interchangeable. Spade, heart, diamond and clover all pay 0.1x or 0.2x for three of a kind, and none of them breaks 1.5x even for five. The gap between the amulet and the spade below it is where the paytable drops off a cliff.
Wins land on 24.65% of spins, roughly one in four. With the wild still unupgraded, most of those connections draw on the lower half of the table. The picture symbols carry the game; the royals exist to keep the counter ticking.
The Zillard Wild Progress Bar
Gold Coins can appear in the bottom right-hand corner of any symbol on the reels, but only while upgrades remain to be unlocked. A coin only counts if it lands on the same spin as a Zillard Wild, which is the game’s way of making you want both at once. Coins that arrive without the wild are simply lost.
That pairing rule shapes every session. A reel full of coins means nothing if the wild stays away, and a wild landing alone leaves the bar exactly where it was. The collection only advances on spins where the two coincide, so progress arrives in bursts rather than a steady drip.
Collected coins fill the progress bar to the right of the reels, and three thresholds unlock three upgrades:
- 30 Gold Coins: the Zillard Wild becomes a stacked 1×4 symbol
- 60 Gold Coins: the Zillard Wild gains a random multiplier
- 90 Gold Coins: the Zillard Wild becomes sticky
The thresholds are cumulative, and the second and third each cost as much again as the first. Thirty coins gets you the stack; the full sticky wild wants ninety in total, which is three times the opening target.
The Three Upgrades
The first upgrade turns the wild into a stacked 1×4 symbol, covering a full reel wherever it lands. On a 5×4 grid that’s an entire reel of wilds, and it changes what a spin can connect in a single move.
The second adds a random multiplier to the wild, so wins it participates in come out above face value. The size of the multiplier isn’t fixed, which keeps the upgraded wild from ever being fully predictable. Two otherwise identical spins can pay differently once this is live.
The third is the one everything has been building towards. At 90 coins the wild turns sticky: it locks to its position and only leaves after it has taken part in at least one win that is then followed by a losing spin. Wins it joins in build a win multiplier that climbs with each consecutive one, up to x20. The first losing spin after a winning run clears the wild from the reels and resets it, taking the multiplier with it.
Once all three upgrades are unlocked, the progress bar disappears for good. From then on the fully upgraded wild is simply part of the game, and the coins stop mattering.
Thunder Wilds
The Roar
When the Zillard Wild lands and the spin doesn’t win, he may roar, and the roar summons Thunder Wilds onto the reels. Between three and six drop while the sixth reel is still locked, and between three and nine once it’s open. Every one of them substitutes for all paying symbols.
The drop triggers a guaranteed win, which makes the roar the game’s most reliable payout: it can’t fire without paying something. It’s a mercy on a quiet spin, and it keeps the reels from going fully silent while the coins are still stacking up. A roar that lands a wild without a win still ends the spin in the black.
There’s a tension built into that design. The roar only arrives on spins where the wild appears and nothing pays, so it’s compensation for near-misses rather than a bonus you can chase. The larger drop range after the sixth reel unlocks means the consolation grows at exactly the point the paytable’s top prizes come into reach.
Our Honest Verdict
Overall Rating: 7.2/10
Sitting through Zillard King is a lot like watching that flat grey sea: mostly quiet, occasionally something surfaces, and the whole appeal is knowing there’s a monster out there getting closer. The reason to choose it is the long build; the wild’s three upgrades are the only thing that changes, and the game knows it, because everything points you at that bar on the right.
The build is also the best thing here. A wild that ends up stacked, multiplied and sticky makes the ninetieth coin matter more than the first hundred spins did, and the roar means a wild that misses never costs you the whole spin.
The weakness is the paytable under all of it, which is flat enough that the early game pays in loose change while you wait. This one belongs with players who enjoy watching a run assemble itself over a long session; anyone who wants their wins early and loud will find the water cold. For the patient, the storm does eventually break, and it’s a good one.
