Play Mermaid’s Diamond in New Zealand

Mermaid’s Diamond does away with paylines altogether and settles wins across 720 ways, reading matching symbols inwards from either end of the reel set. The unusual shape is the reason for the count: Play’n GO stacked five reels three, four, five, four and three positions high, so the game sits inside a diamond outline rather than a rectangle. Released on 20 September 2017, the pokie pairs that layout with an expanding mermaid wild, a Poseidon mechanic and a free spins round opened by treasure chests.

Mermaid’s Diamond Game Overview

Mermaid’s Diamond scores a spin by looking for matching symbols on neighbouring reels, and the number of ways those symbols can line up comes to 720. Because the columns are of different heights, the count is a product of the layout rather than a figure the player chooses. Wins are read both from reel one towards reel five and from reel five back towards reel one.

Mermaid’s Diamond casts the mermaid as its wild and the treasure chest as its scatter, then layers three mechanics over the base game: wild reels, Divine Intervention and a diamond collection that runs inside the bonus. Wildz lists the pokie at medium volatility, with a top result of 5,000 times the stake and no jackpot of any kind attached.

Mermaid’s Diamond is listed by Wildz New Zealand with a default RTP of 91.47%, medium volatility and a maximum win of 5,000x the stake. The precise build and the permitted stake range can differ between operators and markets, which makes the in-game information panel the reliable source for the version actually loaded.

How Does Mermaid’s Diamond Work?

Mermaid’s Diamond takes one stake per spin and that stake covers every one of the 720 ways. Once the reels stop, the game checks each run of matching symbols on adjacent reels, scoring it whether the run begins on the left or on the right. Nothing needs to be selected beforehand, because the pokie has no line count to configure.

Mermaid’s Diamond then applies any wild mechanic that qualifies before the round is closed and the next stake is taken. Symbol positions come out of the game’s random number generator, which means neither the size of the bet nor the pattern of earlier results has any influence on what the following spin will show.

Mermaid’s Diamond 720 Ways to Win

Mermaid’s Diamond arrives at its 720 ways by multiplying the heights of its five columns together. Every one of those ways is live on every paid spin, so a player never has to weigh up how many to activate. Symbols only need to occupy consecutive reels; their vertical position within a column does not matter.

Mermaid’s Diamond treats a right-to-left run as fully as a left-to-right one, giving the pokie its both-ways description. The wider set of qualifying shapes does not translate into a different return, since the 720-way structure is fixed within the game’s programmed mathematics and cannot be widened, narrowed or targeted by any betting approach.

Mermaid’s Diamond Wild Reels

Mermaid’s Diamond expands its mermaid into a full wild reel the moment two or more of her land in the same column. The expanded reel substitutes for standard symbols across every position it occupies, so a single expansion can complete several of the 720 ways in one go. An expansion on the five-position centre reel has the widest reach.

Mermaid’s Diamond triggers this automatically and charges nothing extra for it. The number of mermaids that reach a reel is simply the random result of that spin, so the wild reel cannot be summoned deliberately, and a stretch of pokies action without one does nothing to change the chance of the next expansion.

Mermaid’s Diamond Divine Intervention

Mermaid’s Diamond gives Poseidon a mechanic of his own, named Divine Intervention. He may lift his trident on any spin and drop additional wild symbols onto the reels, occasionally rescuing a layout that had already settled without a win.

Mermaid’s Diamond calls on the same mechanic near the bonus threshold as well. Where four treasure chests have landed on a non-winning spin, Divine Intervention can add the fifth chest and open the free spins round. Whether it fires is entirely the random system’s decision, so no stake size, session length or autoplay setting shifts the likelihood in a player’s favour.

Mermaid’s Diamond Free Spins

Mermaid’s Diamond opens its bonus when five treasure chests show anywhere across the reels, landing naturally or completed by Poseidon. One chest is then opened, and it reveals how many free spins have been awarded — up to 25. That reveal forms part of the trigger itself rather than being a separate pick round with its own prize table.

Mermaid’s Diamond runs the bonus at the stake that triggered it and carries the 720 ways and the mermaid wild reels through the whole round. The award behind each chest is set by the game before the choice is made, so picking one chest over another cannot steer the round towards its upper limit.

Mermaid’s Diamond Trident Wilds

Mermaid’s Diamond adds a diamond meter that only runs during free spins. Diamonds that land are collected one by one, and reaching five diamonds brings Poseidon back to place Trident Wilds on the reels, where they substitute exactly as the mermaid does.

Mermaid’s Diamond fills the meter through ordinary random results rather than on any timetable. A bonus round can end with the meter part-filled, and the number of spins remaining offers no assurance that the Trident Wilds will be reached at all.

Mermaid’s Diamond RTP

Mermaid’s Diamond carries a theoretical RTP of 91.47% in the version Wildz New Zealand lists. The percentage is a long-run figure calculated over a very large number of spins, and it says nothing about how a particular session will finish. It falls below the level most modern pokies are built to, which is a property of the configuration supplied for this market.

Mermaid’s Diamond is available from Play’n GO in more than one mathematical setting, so the figure attached to another operator’s copy may not match. Opening the in-game information menu before wagering is the way to confirm which percentage applies.

Mermaid’s Diamond Volatility

Mermaid’s Diamond is rated medium volatility. The rating describes how payouts are spread: the 720-way base game tends to return smaller amounts at a steady rate, while the wild reels and the bonus round produce the occasional larger result.

Mermaid’s Diamond applies the same volatility to the base game and the free spins, and it does not change as a session goes on. It is a statement about distribution rather than timing, and a series of losing spins does not make a large win any more likely on the next one.

Mermaid’s Diamond Maximum Win

Mermaid’s Diamond sets its maximum win at 5,000x the total stake. A $1 spin therefore has a theoretical upper limit of $5,000, ahead of any separate limits an operator applies. The pokie carries no jackpot, so nothing sits above that ceiling.

Mermaid’s Diamond would require expanded wild reels, a Divine Intervention and a strong bonus round to come together before the figure was approached. It should be read as the technical top of the game’s mathematics rather than an outcome regular play tends towards.

How to Play Mermaid’s Diamond in New Zealand

Mermaid’s Diamond starts with opening the game, checking the paytable and rules, picking a stake inside the 0.20 to 100 range and spinning. Each paid spin covers all 720 ways, after which the random outcome decides the symbols, any wild expansion and any movement towards the treasure chest trigger.

Mermaid’s Diamond players in New Zealand should confirm the version-specific RTP and stake limits before moving from demo credits to real money. Meeting the 18-year minimum age and completing whatever verification the casino requires both come before the first real-money spin.

Can You Play Mermaid’s Diamond on Mobile?

Yes, Mermaid’s Diamond works on compatible smartphones and tablets. Play’n GO ships a single build for desktop and mobile, so the diamond reel frame, the 720 ways and all three mechanics rescale to a smaller display with nothing removed.

Mermaid’s Diamond usually loads straight into a supported mobile browser, with no download involved. Device age, browser version and connection quality can still make a difference to how the reels and bonus animations perform.

Can You Play Mermaid’s Diamond for Free?

Yes, Mermaid’s Diamond has a demo mode at Wildz New Zealand that runs on virtual credits. The full game is present in the demo, so the mermaid expansion, Divine Intervention and the diamond meter can all be watched without a real balance being staked.

Mermaid’s Diamond demo results cannot be cashed out, because the credits are virtual rather than deposited. The demo is most useful as a way to learn how the pokie behaves before deciding whether real-money play is worthwhile.

Mermaid’s Diamond in New Zealand

Mermaid’s Diamond appears in the Wildz New Zealand catalogue in both demo and real-money form, alongside the wider Play’n GO library. Players can load it in a desktop or mobile browser, review the paytable and stake in New Zealand dollars within the casino’s limits.

Mermaid’s Diamond real-money play sits inside New Zealand’s new online casino framework as well as the operator’s own terms. Age verification, identity checks and any personal deposit or loss limits a player has set apply before a stake is placed.

New Zealand Rules for Mermaid’s Diamond

Mermaid’s Diamond real-money play in New Zealand falls under the Online Casino Gambling Act 2026, which came into force on 1 May 2026 and establishes licensing, player-protection and operator obligations for the sector. The change is being introduced in stages: a transitional period for pre-existing operators runs until 1 December 2026, with the full licensing regime expected during 2027. The Department of Internal Affairs is the authority responsible for administering it.

Mermaid’s Diamond players must be at least 18 years old to gamble online in New Zealand. Operators are required to take reasonable steps to confirm a customer has reached that age before online casino gambling is permitted, and identity verification is part of that process.

Mermaid’s Diamond players should keep in mind that the framework is still being phased in, so operator obligations may change as the transitional period ends. Responsible gambling tools such as deposit caps, loss limits, session reminders and self-exclusion are offered by licensed operators and can be set before real-money play begins.
