Secret of the Castle II RTP (studio benchmark), house edge & 500-spin session math
Secret of the Castle II by Adell runs on a 5×3 / 5×4 HTML5 video grid grid and requires a disciplined 150x–200x session stake buffer in NZ$ at Here2Win Casino (here2win.co.nz).
Because neither Secret of the Castle II nor its wider Adell sheet publishes an RTP percentage in this catalogue, session planning for this pokie at Here2Win Casino (here2win.co.nz) relies on stake discipline: set a 150x–200x buffer in NZ$ and verify the live paytable inside the game help screen before spinning.

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 Secret of the Castle II at Here2Win Casino, stake in NZ$.
Who built this pokie?
The studio on the card is Adell. Fern Spins does not swap in a different name.
Where do I deposit NZ$?
Deposit at Here2Win Casino after the button. POLi can be offered there. Fern Spins only names it so the page is clearly the New Zealand catalogue.
Can Kiwi players open Secret of the Castle II on a phone?
Fern Spins does not publish a separate app. Players in Wellington use the page, then the casino.
What currency is Secret of the Castle II staked in?
NZ$ at Here2Win Casino. This catalogue does not print a minimum, because that figure lives inside the game, not on the card.
Is there a demo of Secret of the Castle II on Fern Spins?
The card is for reading. The session is not hosted on fernspins.co.nz.
Why is Secret of the Castle II 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?
Do not wait out a feature. The pokie is not running late.
Who is Secret of the Castle II for?
Adults, 18+. Fern Spins is a New Zealand catalogue. Gambling can harm, and the page is not a promise of winnings.
