Here2Win Casino plays it. Fern Spins is the New Zealand catalogue. The button leaves via fernspins.co.nz and opens Book of Sirens at Here2Win Casino, stake in NZ$.
Who built this pokie?
The studio on the card is Spinomenal. Fern Spins does not swap in a different name.
Does this site take POLi?
Deposit at Here2Win Casino after the button. POLi can be offered there. Fern Spins only names it so the page is clearly the New Zealand catalogue.
Does Book of Sirens work on mobile in New Zealand?
Yes. The button on fernspins.co.nz is the same on a phone. Here2Win Casino loads the pokie, and the stake is in NZ$.
What currency is Book of Sirens staked in?
NZ$ at Here2Win Casino. This catalogue does not print a minimum, because that figure lives inside the game, not on the card.

Where is the rating for this pokie?
Book of Sirens is not placed above or below the rest of the New Zealand list.
Can Book of Sirens be due to pay?
No. Book of Sirens 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 Book of Sirens for?
Adults, 18+. Fern Spins is a New Zealand catalogue. Gambling can harm, and the page is not a promise of winnings.

fernspins.co.nz takes the click and Here2Win Casino opens the pokie. The partner address stays off the article.
