Archdragon King

Every base-game spin has a chance to drop Gold Coin symbols anywhere on the reels. Each coin you land fills the evolution meter, and hitting the thresholds 30 / 60 / 90 permanently unlocks the next dragon stage. The meter does not reset mid-session — it carries across spins until you cash out or close the round.

Each stage grows the Dragon Wild vertically (1x2, then 1x3, then 1x4) and boosts its multiplier. The final stage also reveals the top row, expanding the grid from 5x3 to 5x4 and lifting the ways to win from 243 to 1,024. You don't "choose" stages — collecting coins is the only lever, which is why high-volatility sessions frontload small bets to build the meter before pressing stakes.

From the first evolution stage, when a Dragon Wild contributes to any winning way it turns sticky and stays on its reel for one more spin. From Stage 2 onward, its multiplier climbs by +1 each time the sticky Wild helps make a win, so a Wild that keeps landing in wins keeps ratcheting its multiplier higher.

Here's the subtlety most players miss: the Wild stays sticky only through spins where it keeps contributing to wins. On a spin where it doesn't help make a win, it disappears and its accumulated multiplier resets. Because the Dragon can cover a full 1x4 column by Stage 3 on 1,024 ways, a sticky chain on the middle reels is where the bigger base-game hits tend to build.

Archfire is a silent random trigger that only fires on non-winning spins where a Dragon Wild is on the reels. When it activates, the dragon breathes fire and ignites a reel, cloning the Dragon Wild leftward across the grid. The extra Wilds then evaluate for wins as if they had landed on the spin.

It's a catch-up mechanic: it turns a dead spin with a Wild showing into a chance at a win, so more of your near-misses convert into paying combinations.

Land 3, 4 or 5 Scatters to trigger 7 Free Spins. A sticky Dragon Wild is placed on the middle reel for the whole bonus, and triggering with more Scatters seeds it at a higher starting multiplier: a standard start on 3 Scatters, x10 on 4 Scatters, and x25 on 5 Scatters. Landing another Scatter during the bonus retriggers it for +2 extra spins.

The bonus plays on the fully expanded 5x4 grid (1,024 ways). With the Wild locked in place and its multiplier building through the round, the Free Spins is where the run at the 20,000x ceiling actually happens.

Archdragon King's three Feature Buy tiers don't just skip the wait — each buys a different bonus start. The cheaper tier drops you into the standard Free Spins, while the pricier tiers seed the sticky Wild with a higher starting multiplier, which matters because that Wild carries its multiplier through the round.

Each tier mirrors a natural trigger: 80x is the equivalent of 3 Scatters, 160x of 4 Scatters (x10 Wild), and 300x of 5 Scatters (x25 Wild). Note that bonus buys are switched off in some regulated markets such as the UK, where the bonus is natural-trigger only.
