Sharky RTP (studio benchmark), house edge & 500-spin session math
Sharky by Greentube benchmarks against the verified 95.05% studio average RTP (4.95% house margin across 135 titles) and suits a 200x–250x stake buffer in NZ$ at Here2Win Casino (here2win.co.nz).
Sharky does not carry a standalone RTP on its source sheet, so Fern Spins cites the verified studio distribution instead of guessing. The pokie runs on a 5×3 / 5×4 HTML5 video grid layout, and its variance profile fits a 200x–250x unit-stake reserve when playing Sharky in NZ$ at Here2Win Casino (here2win.co.nz).
| Session volume & entity | Total turnover | Theoretical return | House margin | Est. winning spins |
|---|---|---|---|---|
| 100 spins on Sharky (NZ$1/spin @ 95.05% RTP) | NZ$100 | NZ$95.05 | NZ$4.95 | ~27–33 |
| 250 spins on Sharky (NZ$1/spin @ 95.05% RTP) | NZ$250 | NZ$237.63 | NZ$12.38 | ~68–83 |
| 500 spins on Sharky (NZ$1/spin @ 95.05% RTP) | NZ$500 | NZ$475.25 | NZ$24.75 | ~135–165 |

What this pokie is
Fern Spins keeps the New Zealand entry plain. Sharky is from Greentube. You play it at Here2Win Casino. The stake shows in NZ$.
Fern Spins keeps the New Zealand page for Sharky on its own host. The sentence is not the Australian page with the country find-replaced. The play button still ends at Here2Win Casino.
The preview under the title is there so a snippet and the page say the same thing. If the list above has a gap, the preview keeps the gap.
Diamond Mystery Mega Blaze and Gems of Giza are two more Greentube pokies on this list.

Questions
Does Fern Spins play the pokie itself?
Here2Win Casino plays it. Fern Spins is the New Zealand catalogue. The button leaves via fernspins.co.nz and opens Sharky at Here2Win Casino, stake in NZ$.
Which studio is Sharky from?
The studio on the card is Greentube. Fern Spins does not swap in a different name.
Where do I deposit NZ$?
NZ$ stays in the Here2Win Casino account. This domain does not open a cashier.
Does Sharky work on mobile in New Zealand?
Yes. The button on fernspins.co.nz is the same on a phone. Here2Win Casino loads the pokie, and the stake is in NZ$.
What currency is Sharky staked in?
You set the NZ$ stake after the handoff. fernspins.co.nz never holds it.
Can I play Sharky on this page?
The card is for reading. The session is not hosted on fernspins.co.nz.
Where is the rating for this pokie?
There is no rating. A score would be an opinion Fern Spins refuses to invent. The useful lines are the studio, the RTP when it exists, and the volatility.
Does the pokie remember the last session?
Do not wait out a feature. The pokie is not running late.
Who is Sharky for?
Adults, 18+. Fern Spins is a New Zealand catalogue. Gambling can harm, and the page is not a promise of winnings.
What happens when I press play on Sharky?
fernspins.co.nz takes the click and Here2Win Casino opens the pokie. The partner address stays off the article.
How many Greentube pokies are on this site?
419. They are grouped on the provider page. Sharky is a single title in that group, played at Here2Win Casino.
Does Christchurch change the pokie?
No. The same Sharky card applies across New Zealand. City is not a reel setting. NZ$ and POLi are the local pieces, and both are settled at Here2Win Casino.
Is a bonus amount listed for Sharky?
No amount is printed here. A welcome offer, if Here2Win Casino has one, is shown in the account with its own terms. Fern Spins will not guess the numbers.
Is Sharky a pub pokie?
No. It is an online pokie from Greentube, opened at Here2Win Casino. The page does not describe a machine in a venue.
How do I finish a session?
Decide the NZ$ limit before the reels move, then stop when it is reached. Sharky will not tap you on the shoulder.
Why does Sharky have no RTP?
The source card did not publish one. The gap stays empty. A figure is not copied from another pokie to make the page look finished.
Why list pros and cons for Sharky?
It is not a rating of Sharky. A pro means the card or the catalogue actually supports the line. A con means a missing figure or a limit of this page.
Is the text under the title the preview?
Read it as a card, not as a tip for Christchurch. The pokie does not know the city, and the page does not pretend it does.
Will a shorter name still open Sharky?
Use the full name on this card. A shorter search in the Here2Win Casino lobby can open a different Greentube title.
How many reels and paylines does Sharky have?
A count of free spins and a bonus-buy price are also absent. Those numbers stay off the page.
Which feature labels are on Sharky?
Expanding Symbols and Gamble Feature is the whole feature list for Sharky. Those words are not a price and not a description of the round.
How a session moves
Plain version for Fern Spins: limit, spin, stop. That is the whole note.
It is not a plan to clear an offer. Any welcome lives inside Here2Win Casino, and Fern Spins does not invent the terms.
Stake and POLi
Fern Spins takes no NZ$. POLi, if you use it, is at Here2Win Casino.
POLi and the other rails people in New Zealand already use are handled inside the Here2Win Casino account. fernspins.co.nz never asks for them. The page cannot take an NZ$ deposit.
Who it suits
The card has no volatility mark. Fern Spins leaves that gap empty instead of guessing a fit for Sharky. The session, if you open it, is at Here2Win Casino.
