Zillard King builds its identity around a Wild that changes in stages. Gold Coins feed a progress bar only when they land on the same spin as a Zillard Wild, and the accumulated total unlocks three upgrades before the meter becomes a sixth reel. That conditional collection rule is the key to the game: coins are not collected simply because they appear, and the Wild’s improvements arrive through milestones rather than a single bonus trigger. The result is a five-reel line slot with a long-term system that can alter both a symbol and, eventually, the board.

Coins must meet the Wild
The game starts with five reels, four rows and up to 30 paylines. Gold Coins may show at the bottom-right corner of symbols while upgrades remain, but a coin contributes to the meter only when a Zillard Wild lands in that same spin. This pairing makes progress dependent on two events occurring together. The meter needs 30 coins for the first upgrade, 60 for the second and 90 for the third. Once the final milestone is reached, the progress bar turns into an extra sixth reel on which only high-paying symbols can land.
The upgrades arrive in order. First the Zillard Wild becomes a stacked 1×4 symbol. Next it gains a random multiplier. The third upgrade makes it sticky: it remains locked until it has participated in at least one win and then a non-winning spin occurs. During consecutive wins in which the Zillard Wild participates, its win multiplier increases up to 20x. That wording ties growth to consecutive qualifying wins, not every spin or every win anywhere on the grid. The distinction prevents overreading the headline multiplier as a permanent value on all outcomes.
A miss can still trigger Thunder
There is a second response when the Zillard Wild arrives without producing a win. Zillard then summons Thunder Wilds, which substitute for all paying symbols and create a guaranteed win. Before the sixth progress reel is unlocked, three to six Thunder Wilds may drop; after that unlock, the range is three to nine. This makes an unsuccessful Wild landing a trigger for another symbol event, though the source does not specify the exact random count within either range. The later sixth reel also changes the possible board content, so it is a progression reward rather than simply another stacked Wild.
The interactions form a chain: a coin and Wild together advance upgrade progress, and each upgrade changes the Wild’s shape, multiplier or persistence. Once all three are unlocked, the meter becomes a reel of high-paying symbols. Separately, a non-winning Zillard Wild calls in Thunder Wilds. Coins appearing without the Zillard Wild do not advance the bar, making the pace of the upgrades depend on that pairing.
Configuration and assessment
Red Tiger lists 95.69% RTP, volatility index 17.34 and no maximum-win figure in its game data. The maximum must therefore remain unspecified; a sixth reel or a multiplier ceiling is not a substitute for a published maximum payout. The listed layout is five reels by four rows with up to 30 lines. The source’s numeric volatility index is presented as a number rather than assigned a verbal category. Readers should treat these as the provider listing’s figures, not assume that every operator uses identical math.
The Thunder Wild response gives a non-winning Zillard Wild a distinctive role, while the coin meter supplies a longer sequence of upgrades. Each milestone changes something visible, culminating in the sixth reel. The trade-off is that coins count only when they share a spin with the Zillard Wild; the rules do not state how often that pairing occurs.
Wolfkin — Both games evolve a featured Wild, but Zillard King advances through coin milestones while Wolfkin transforms Stone Wolves when its central Super Wild appears.
Strengths and weak points
Strengths
The Wild’s upgrades have distinct jobs, and Thunder Wilds give a documented consequence to a non-winning Zillard Wild instead of leaving that event unexplained.
Weaknesses
Coins advance the meter only when a Zillard Wild appears on the same spin, and no published maximum-win figure or event probability clarifies the progression’s upper outcome.
Our Editor’s View
Zillard King gives its central Wild a progression from stacked symbol to multiplier and sticky upgrades, ending with a sixth reel of high-paying symbols. Thunder Wilds add a separate response to a non-winning Zillard Wild. The sequence is easy to follow, but coins count only when they land with the featured Wild, so progress depends on that pairing. Red Tiger does not list a maximum payout figure.
