Jade Coins: Prosperity collector and Lucky Time rules

Jade Coins is a three-reel, three-row Endorphina slot with five fixed paylines. The official page checked on 8 October 2026 publishes 96.06% RTP, medium-high volatility, a €0.05–€80 reference stake range and Approved status. Three Golden Coins across all three reels trigger Prosperity Coins Bonus, while two may activate Lucky Time.

The bonus uses a 3×3 collector. Jade Coins lock on reel two and accumulate prizes carried by Gold Coins on reels one and three. The resulting value depends on position and sequence, not simply the number of coin graphics.

These figures do not confirm an NZ operator listing, NZD stake ladder, deployed RTP or current jackpot values. They are provider evidence only.

Five-line base game

Save the five fixed paths and evaluate ordinary symbols along them. Record line number, matching sequence and any Maneki-neko Wild substitution.

Gold bowls are listed at 20× base bet for three of a kind, while chests are listed at 30×. Five Wilds are described at 50× base bet even though the visible grid is 3×3; this wording should be checked against the current paytable rather than silently corrected.

That apparent conflict is exactly why screenshots and a game version matter. Report what live help actually shows and flag inconsistent supplier copy.

Maneki-neko Wild

The cat Wild substitutes for ordinary symbols except special symbols and appears only in the main game. It does not become a Jade Coin, Gold Coin or trigger.

Mark the original Wild cell, then identify each fixed line it completes. Do not carry it into Prosperity Bonus, where the symbol set and settlement model change.

If the loaded table contradicts the supplier’s “five Wilds” statement, preserve both sources with dates and avoid inventing an explanation.

Three-coin trigger

The product text says three Golden Coins appearing simultaneously on all three reels trigger Prosperity Coins Bonus. Record each coin coordinate and confirm that every reel is represented.

The symbol summary also describes “3+ coins on all 3 reels”. Do not treat three coins confined to two reels as the standard trigger unless current help explicitly allows it.

Triggering coins move to corresponding positions in the bonus grid, so their initial coordinates should match the starting collector state.

Lucky Time from two coins

Two Golden Coins may activate Lucky Time according to the supplier description. “May” indicates a conditional route, not a guaranteed trigger for every two-coin result.

When it occurs, save the two source positions, any invitation screen and the starting collector. Do not label a normal two-coin near miss as a malfunction.

The live help should explain selection or probability conditions. If it does not, record the activation as observed without assigning an unpublished rate.

Prosperity Coins grid

The bonus uses nine positions containing Jade Coins, Gold Coins and empty patterned cells. Jade Coins on reel two stick until the feature ends. Gold Coins on reels one and three supply prizes that Jade Coins accumulate.

Draw three columns and three rows. For every respin, record newly landed coins, printed values and which centre Jade receives each Gold value. Keep the accumulation ledger for each Jade Coin separately.

Once values are collected, outer reels continue spinning while the centre coins remain. The final award is the sum displayed on all Jade Coins present at the end.

Regular prizes and jackpots

The official symbol entry mentions regular prizes up to 15× total bet plus MIN, MID, MAX and ULTRA jackpots. “Up to” is a ceiling, not the value of each ordinary coin.

Use the current help to identify how jackpot symbols land or attach to Jade Coins. Record the named level and credited amount. Do not call a jackpot progressive unless the loaded rules say the amount changes dynamically.

The overall description mentions wealth up to 1000× total bets. Treat that as a published ceiling only if the current version’s help supports the condition and wager basis.

Collector arithmetic

At entry, write the triggering coin positions. Give every centre Jade an identifier such as J1, J2 or J3. As outer Gold Coins land, append their values to the relevant Jade ledger.

At completion, total each Jade once, list jackpots separately and compare the combined result with history. Avoid adding both individual Gold values and the already accumulated Jade total.

If the interface displays a cumulative counter, note whether it is inclusive. A running animation can otherwise be mistaken for a series of separate credits.

Risk, RTP and account scope

Classic Risk is listed as an optional post-win game with up to ten decisions. It follows settlement and does not change the collector. An operator can disable it.

The 96.06% RTP is a supplier theoretical value. Medium-high volatility does not predict Lucky Time or a jackpot. The €0.05–€80 range remains euro metadata, not an NZD claim.

No Bonus Pop is listed. Do not import a purchase option from another Endorphina coin game.

Mobile and demo checks

On a phone, verify that all nine cells and accumulated centre values remain readable. Test history, stake display and feature transitions in both orientations.

A permitted demo can reveal coin flow, but cannot establish real-money availability or cash limits. Record the URL, browser and check date.

For a dispute, preserve round ID, game version, currency, total stake, starting grid, respin sequence, centre ledgers and final history credit. Original timestamps help support trace the event.

Common mistakes

• Counting three coins without one on every reel.
• Treating Lucky Time as guaranteed from any two coins.
• Allowing Wild to replace a special coin.
• Summing Gold values twice after they enter a Jade total.
• Calling every named jackpot progressive.
• Presenting 15× as a fixed regular prize.
• Ignoring the five-Wild wording conflict.
• Converting euro stakes into asserted NZD limits.

Building the coin-transfer matrix

Label the outer cells G11–G13 on reel one and G31–G33 on reel three. Label centre positions J21–J23. For every Gold Coin, record its printed value, landing step and destination Jade Coin according to the live animation and help. Each centre ledger should show a running total after the transfer.

If a Gold value appears while no corresponding Jade is active, do not assume it is stored for later. Record what the interface does. Likewise, when a new Jade arrives after earlier Gold Coins, rely on the current rule rather than retroactively assigning past values.

At the final state, compare each displayed Jade total with its transfer ledger. Then sum the centre values once. Named jackpot symbols should occupy their own rows because their settlement may not behave like a regular numeric coin. This matrix exposes the precise step where a disputed total diverges.

Testing the Lucky Time route

Lucky Time is conditional after two Golden Coins, so a useful observation includes both activations and non-activations. Record the two reel positions, stake, version and any extra animation. A small sample cannot establish the probability, but it can confirm the route and the collector state that follows.

Do not increase play merely to estimate the activation rate. Editorial evidence should come from permitted observations or official help, not from chasing an uncertain event. If no rate is disclosed, state that it is unavailable.

Jackpot evidence checklist

For MIN, MID, MAX or ULTRA, save the named symbol, the cell where it landed, the stake basis, displayed amount and final transaction entry. Determine whether the award is a fixed multiple or a changing monetary pool. A label alone cannot establish progressiveness.

If the interface uses total-bet multipliers, keep those separate from base-bet line wins. Record decimal precision and account currency before reconciling the closing balance.

Resolving the paytable inconsistency

The supplier’s “five Wilds” phrase conflicts with the visible 3×3, three-reel structure. The correct editorial response is not to rewrite it silently. Check the live paytable, capture its exact Wild row and identify the game version. Publish the supported live value and note that the public symbol copy was inconsistent on the check date.

This approach preserves evidence without amplifying an obvious ambiguity into a false rule.

Record the correction date if Endorphina later updates that wording.

Final assessment

Jade Coins is compact but evidence-heavy. The base game has only five lines; the real audit work is preserving source positions and tracking how each centre Jade accumulates outer-reel values.

The official page supports 96.06% RTP and the collector structure. Live help must confirm exact trigger handling, Lucky Time, jackpot conditions, currency, stakes and settlement.

How to verify the version you can actually open

A provider page proves that a title exists and describes the supplier's intended rules. It does not prove that a casino accepts players in New Zealand, that the title is enabled for a particular account, or that the highest published RTP is the version in the lobby. Treat availability, operator eligibility and product configuration as three separate checks.

Start with identity, then configuration

Open the game only through the authenticated casino lobby. The information or help panel should identify Endorphina, the exact title and the active mathematical return. Compare the reel or grid layout, paylines or cluster rules, named features and symbol behaviour with the official product material. Similar artwork or a matching title is not enough when the help file is missing or inconsistent.

When the supplier publishes several RTP values, report all of them as configurations. Do not assume the highest option is deployed. RTP is a theoretical long-run measure across a very large number of rounds; it is not a refund rate for one player and cannot predict the next result. Volatility is different: it describes how unevenly results are distributed on the provider's scale.

Read stake controls as money, not interface decoration

Provider sheets often quote a reference range in euros. That range does not establish New Zealand-dollar support or the limits in a specific account. Before a paid round, identify the total amount that will leave the balance. If the interface separates denomination, coins and lines, verify the combined total. If Extra Bet is active, calculate its full cost before pressing spin.

Feature-buy prices are multiples of the current bet, not promised returns. A 100x purchase at a $1 stake costs $100; at a $2 stake it costs $200. Availability can vary by market and some mathematical configurations may not support the control. If the live help does not explain the price, delivered feature and active RTP, leave the option unused.

Keep simulation figures in their proper scope

A game sheet may publish a maximum result observed in a large simulation. That is not automatically the contractual maximum payout and never describes a likely session. Preserve the provider's wording, sample size and configuration. Check the live rules for a binding cap and the operator terms for any separate payout limit. Do not turn an extreme result into a promotional headline.

Audit a disputed round

If an animation freezes or a connection drops, do not repeat the wager immediately. Reopen the game through the authenticated lobby and inspect round history. Record the time, total stake, balance movement and round identifier. The result can be settled by the gaming system even when the device never displays the final animation. Send evidence through verified operator support; never disclose a password, recovery phrase or one-time code.

Read the paytable as a calculation document

The paytable should explain what creates a win, which symbols substitute, where special symbols can land and how multiple awards combine. For line games, confirm direction and active paylines. For cluster games, confirm adjacency, minimum group size and the order of collection. For respins, identify what remains locked, what resets the counter and what ends the feature. A graphic effect can illustrate those rules but cannot replace them.

Separate addition from multiplication. Several prize values may be added before a multiplier applies, while reel-specific multipliers can sometimes multiply together only when each reel participates in the same win. Reconstruct one low-stake result from game history. If the arithmetic cannot be matched to the help file, stop and ask the operator rather than guessing.

Do not confuse hit frequency with a profitable round

Provider sheets can publish hit frequency or category probabilities. A hit simply means a round returned a qualifying amount; it can be smaller than the stake. “Big”, “Mega” or “Epic” thresholds are provider reporting categories, not promises. They are useful for comparing mathematical versions only when definitions and samples are the same.

Random outcomes do not become due after a long gap. A feature that appeared repeatedly in a demo or marketing clip has no obligation to repeat in a funded session. Previous rounds do not create a debt from the next random result.

Confirm market and device behaviour independently

A title can exist in the supplier catalogue while an operator disables it for a territory, currency, device or bonus. Language localisation is not evidence of legal availability. Confirm the operator's identity, accepted countries and current lobby separately from the provider review.

On mobile, verify that balance, total bet, feature state and help remain visible without overlap. On desktop, check that browser zoom does not hide a purchase control or change the apparent denomination. Mathematical configuration should not change merely because the screen changes; if the help shows another RTP, treat it as a different deployment and record it.

Keep a compact evidence record

For any fact used in a review, save the title, provider, official URL, document date when available, access date and exact territorial scope. For a live session, add the operator domain, Game ID, RTP, currency and a non-sensitive screenshot of the help panel. This makes later corrections possible when a supplier updates a sheet or an operator changes configuration.

Missing information should remain missing. Do not estimate an RTP from results, convert a euro reference range into an operator's NZD limit, or treat another casino's configuration as evidence. A transparent “not confirmed” is more useful than a precise-looking number without the correct source.

Use limits that survive the feature design

Collection meters, expanding grids, sticky symbols and near misses can make a session feel unfinished. Unless the rules explicitly preserve progress, the visible state has no value after the round or feature ends. Set a money limit and time limit before launch, count feature buys immediately, and stop at the limit even when a meter appears close to an upgrade.

No random game is an income plan. Do not borrow, use essential funds or raise the stake to recover a loss. If play stops feeling recreational, use timeout, deposit-limit or self-exclusion tools and consult the site's responsible gambling guide.
