Coin Blast RTP (studio benchmark), house edge & 500-spin session math
Coin Blast 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).
Because the source card for Coin Blast omits an individual percentage, this Greentube release is benchmarked against the studio's published range (92.13% to 96.45%). The pokie runs on a 5×3 video grid (with Hold & Win bonus board) layout, and its variance profile fits a 200x–250x unit-stake reserve when playing Coin Blast in NZ$ at Here2Win Casino (here2win.co.nz).
| Session volume & entity | Total turnover | Theoretical return | House margin | Est. winning spins |
|---|---|---|---|---|
| 100 spins on Coin Blast (NZ$1/spin @ 95.05% RTP) | NZ$100 | NZ$95.05 | NZ$4.95 | ~27–33 |
| 250 spins on Coin Blast (NZ$1/spin @ 95.05% RTP) | NZ$250 | NZ$237.63 | NZ$12.38 | ~68–83 |
| 500 spins on Coin Blast (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. Coin Blast is from Greentube. You play it at Here2Win Casino. The stake shows in NZ$.
The video group is where Fern Spins files this pokie for New Zealand. The provider page is the clean way to do that. Each of those pages repeats the handoff: this domain, then Here2Win Casino.
Across New Zealand the reel strip does not change by city. Fern Spins writes the facts once, on this URL.

Questions
Does Fern Spins play the pokie itself?
Yes, Coin Blast is on this New Zealand list. The session is not hosted on fernspins.co.nz.
Which studio is Coin Blast from?
Greentube. Other Greentube pokies for New Zealand are grouped on the provider page.
Where do I deposit NZ$?
NZ$ stays in the Here2Win Casino account. This domain does not open a cashier.
Does Coin Blast work on mobile in New Zealand?
Fern Spins does not publish a separate app. Players in Wellington use the page, then the casino.
What currency is Coin Blast staked in?
You set the NZ$ stake after the handoff. fernspins.co.nz never holds it.
Is there a demo of Coin Blast on Fern Spins?
The card is for reading. The session is not hosted on fernspins.co.nz.
Why is Coin Blast not scored?
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?
No. Coin Blast does not keep your last evening, in Wellington or anywhere else. The RTP, when printed, is a long sample, not the next spin.
Who is Coin Blast 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 Coin Blast?
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. Coin Blast is a single title in that group, played at Here2Win Casino.
Does Wellington change the pokie?
No. The same Coin Blast 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 Coin Blast?
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 Coin Blast 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. Coin Blast will not tap you on the shoulder.
Why does Coin Blast 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 Coin Blast?
It is not a rating of Coin Blast. 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?
Yes. That short answer is the preview, and it should match the fact list: Greentube, and only when you are on a card that has an RTP. Pros and cons come after, in plainer lines.
How do I open the right Coin Blast?
Use the full name on this card. A shorter search in the Here2Win Casino lobby can open a different Greentube title.
What is the maximum win on Coin Blast?
A count of free spins and a bonus-buy price are also absent. Those numbers stay off the page.
What features does the Coin Blast card list?
The labels are Expanding Symbols and Gamble Feature. They are names only. This page does not add a bonus amount, a free-spin count, or a jackpot figure.
How a session moves
Coin Blast does not become likelier because the page is short. 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 Coin Blast. The session, if you open it, is at Here2Win Casino.
