ARCHDRAGON KING — Ascend to the Frozen Peaks

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 does three things simultaneously: it grows the Dragon Wild vertically, boosts its base multiplier, and unlocks more ways to win by adding rows to the grid. 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.

When a Dragon Wild contributes to any winning way, it locks onto its reel for the very next spin. The catch: its multiplier does not reset — it carries forward and adds to whatever new multiplier the Wild rolls that spin. A x3 Wild that wins, then respawns and rolls x5, is applied as x8 to any win it touches.

Here's the subtlety most players miss: the Wild stays sticky only until a spin where it doesn't contribute to a win. Since the Dragon covers 1-4 full rows by Stage 3, a sticky chain on reel 2 or 3 can run 4–7 spins in a row on 1,024 ways — this is where the bulk of 500x+ base-game hits happen. Small caveat: if the Wild is overwritten by a 1x4 evolution upgrade, the old multiplier resets.

Archfire is a silent random trigger that only fires on non-winning spins where a Dragon Wild landed. When it activates, the dragon breathes fire leftward across the reels and clones the single highest-paying symbol on the grid into every position to the left of the Wild. The cloned column then evaluates for wins as if those symbols were always there.

Archfire only clones premium symbols (Blue Dragon, Red Dragon, King) — low-pay card royals are skipped, which keeps the payout density meaningful. Rough estimate: fires on ~1 in 15-20 qualifying dry spins, and when it does, average payout is 8-40x bet. It's the reason Archdragon King feels less punishing than its "Extreme" label suggests during Stage 2-3 sessions.

Land 3+ Scatters to trigger 7 Free Spins. A permanent Dragon Wild (sticky the entire bonus, not just after wins) is placed on reel 2 or 3 at a starting multiplier that scales with your trigger: x10 for 3 Scatters, x15 for 4, x25 for 5. Extra Scatters landing during the bonus add +2 spins each and bump the Wild by +x1 to +x5 per Scatter, with no visible cap.

The grid always starts at 5x4 (1,024 ways) regardless of what you reached in base game — the bonus doesn't borrow your evolution progress. What it does borrow: Archfire still fires on dry spins with a higher rate (~1 in 10), and cloned columns feed straight into the sticky Wild's multiplier. A single 7-spin bonus with 3–4 retriggers and the Wild sitting at x40+ is what produces the 2,000x–8,000x bonus outcomes you'll see in clip reels.

Unlike most slots where Feature Buy options are just cost variations of the same bonus, Archdragon King's three tiers actually change the starting conditions. Paying more doesn't just skip the wait — it drops you into a higher-mult Free Spins seed, which matters because the sticky Wild carries its starting multiplier through every spin.

RTP varies across tiers: 80x buy runs at ~96.0%, 160x at ~96.1%, and 300x at ~96.2% — the premium buy is marginally more efficient, contrary to the usual "buy-in tax" pattern. Restriction: buys are disabled in several jurisdictions (UK, NL, DE); in those, the bonus is natural-trigger only.
