Prosperity Coins Bonus Game — Full Mechanic
Hold & Win · 3 respins · Jade Coin collects from reels 1 and 3
The Prosperity Coins Bonus Game is where every meaningful win on Jade Coins happens. The base game delivers small payouts — this feature delivers the jackpots. Below: exactly how the trigger works, what happens during the three respins, why the middle reel matters most, and how the math favours certain coin configurations.
How to Trigger the Bonus
The primary trigger requires three Gold Coins — one on each of the three reels — landing simultaneously. When that happens, the base game freezes, the reels reconfigure, and the Hold & Win round begins. A softer secondary trigger exists: two Gold Coins on the reels can activate the Lucky Time / Money Rain bonus, a lesser version that doesn't give the full respin mechanic. The full three-coin trigger is what you're chasing. Average frequency sits around one in 100-150 spins at standard variance, though individual sessions can run much longer between hits.
What Happens on the First Bonus Spin
When the bonus starts, the 3×3 grid shifts into Hold & Win mode. The three triggering coins lock into their positions. You're awarded 3 respins. On each respin, new Gold Coins can land on reels 1 and 3 — each carrying a cash value (1×, 2×, 5×, or 15× your stake) or one of four jackpots. A Jade Coin (the green one) can only land on the middle reel. When it does, it stays locked for the rest of the round and starts collecting. Every time the respin counter hits zero without new coins landing, the round ends.
The Jade Coin's Collection Mechanic
The Jade Coin is the slot's most important symbol. It doesn't carry a prize itself — it collects them. When a Jade Coin lands on the middle reel, it automatically claims every cash value currently showing on the Gold Coins around it on reels 1 and 3. After collecting, it stays in place. The Gold Coins on reels 1 and 3 keep spinning, replacing themselves with new values each respin. Each new value gets collected by the Jade Coin. You can hold up to three Jade Coins simultaneously on the middle reel — and each collects independently. A full middle reel of three Jade Coins, each pulling from fresh Gold Coins across 3+ respins, is how the biggest wins happen.
The Respin Reset — Why Coins Matter More Than Spins
The 3-respin counter only decrements when no new coin lands. If a Gold Coin or Jade Coin appears on a respin, the counter resets back to 3. This is the engine of the mechanic. A long Prosperity round — one that triggers a big payout — is really a chain of resets. One coin per respin keeps the round alive indefinitely in theory. In practice, the average successful round chains 5-7 coins before the counter runs out. A short round (3 respins, no new coins, just the original three) is the disappointing outcome. A long round (12+ coins collected) is where the jackpots enter play.
The Four Jackpots Inside the Bonus
Jackpot coins are rare variants of regular Gold Coins. Instead of a cash value (1×, 2×, 5×, 15×), they carry one of four fixed jackpot multipliers: MIN (25×), MID (50×), MAX (150×), ULTRA (1,000×). When a Jade Coin collects from a jackpot coin, it claims the full jackpot value. ULTRA at 1,000× is the hard cap — the single largest win possible on Jade Coins. A theoretical bonus round that collects multiple jackpots is capped: the game won't pay above 1,000× total across the entire round. If you see the ULTRA appear, that's the session ceiling right there.
What Ends the Round — And What to Do When It Does
The round ends one of two ways. Either you run out of respins (3 consecutive spins with no new coins), or every position on the grid fills with a coin. When the round ends, the game tallies up the total collected by all Jade Coins on the middle reel, adds any jackpot values, and adds that total to your balance. After the round, the Gamble option becomes available — you can double the bonus win by guessing a dealer card correctly. Same rules as the base-game Gamble: watch the dealer's card. Low card = consider it. High card = collect and move on.
