Book of Secrets card on Boomerang Pokies
Australian punters can open the session page for Book of Secrets pokie apart from this catalogue.
On Boomerang Pokies, Book of Secrets is the SYNOT Games pokie Australian players launch through Here2Win Casino. The studio name and the game name are the hard facts on this page. Stake in A$ and stop when the session stops being fun.
What this pokie is
Boomerang Pokies sends you out and back: read Book of Secrets here, play it at Here2Win Casino, return to the same URL if you want the figures again. The pokie itself does not boomerang a loss into a win.
Start Book of Secrets from Boomerang Pokies and the play button stays on this domain before Here2Win Casino loads the pokie. Punters in Perth usually do it from a phone. You choose the stake inside the game, in A$.
The preview under the title is the short form of this card. The description tag repeats that sentence. Boomerang Pokies does not decorate the preview with a guessed return.
The studio behind it
SYNOT Games is the studio printed on Book of Secrets. Boomerang Pokies lists 168 of their pokies for Australia, and this is one of them. Open that page if you want a neighbour title from the same studio.
Boomerang Pokies groups Chilli Joker with the other SYNOT Games pokies.

Session math & RTP benchmark
Book of Secrets does not carry an individual published RTP on its source sheet, so no single-title percentage is guessed. Across the 17 SYNOT Games titles that do publish a return in this catalogue, the studio average is 95.99% (ranging from 95.90% to 96.05%). For a balanced session at Here2Win Casino, a bankroll buffer of 200x–250x the A$ unit stake suits this pokie's profile.
| Session volume | Total turnover | Theoretical return | House margin | Est. winning spins |
|---|---|---|---|---|
| 100 spins (A$1/spin) | A$100 | A$95.99 | A$4.01 | ~27–33 |
| 250 spins (A$1/spin) | A$250 | A$239.97 | A$10.03 | ~68–83 |
| 500 spins (A$1/spin) | A$500 | A$479.95 | A$20.05 | ~135–165 |

More from SYNOT Games
Who it suits
This card does not carry a volatility mark, so Boomerang Pokies does not guess who Book of Secrets suits. The studio is SYNOT Games. The session still opens at Here2Win Casino.
How a session behaves
The return trip is just another session. Keep the A$ stake where you left the rule.
A fair session on Book of Secrets is a run of spins you can afford to lose, not a plan to clear a welcome offer. Boomerang Pokies does not print a bonus figure it does not hold.
Questions
Can I play Book of Secrets at Here2Win Casino from Australia?
Book of Secrets is in the Boomerang Pokies list for Australia, and the session itself runs at Here2Win Casino. Use the play button rather than hunting the game by a different name.
Which studio built Book of Secrets?
SYNOT Games is the studio named on the Book of Secrets card. Boomerang Pokies groups the rest of that studio on the provider page.
Is this page the casino, or a catalogue?
You are reading a catalogue page. Deposits, PayID and the spin itself belong to the Here2Win Casino account, not to boomerangpokies.com.
Can I open Book of Secrets on a phone?
Punters in Perth mostly open Book of Secrets from a phone. Boomerang Pokies does not ship a separate app. The button hands the pokie to Here2Win Casino.
Is Book of Secrets staked in A$?
At Here2Win Casino the stake for Australian players is in A$. Boomerang Pokies does not convert it and does not print a minimum, because the minimum is set inside the game.
Is there a demo of Book of Secrets on this page?
This page is the written card. It does not run the reels, free or paid. Play happens at Here2Win Casino.
Does Boomerang Pokies score Book of Secrets?
No score is printed on purpose. A star would be a house opinion. The page sticks to the studio, the published RTP when the card has one, and the volatility label.
Does Book of Secrets remember my last session?
No. Book of Secrets does not store the night you had in Perth, and it is not due. A published RTP describes a very long run of spins, not the next one.
Is Book of Secrets an 18+ game?
18+. Boomerang Pokies is a catalogue, and Here2Win Casino is where the session runs. Do not open the pokie if you are under 18.
What does the play button actually do?
The click stays on boomerangpokies.com first, then opens Book of Secrets at Here2Win Casino. The partner address is not printed in the article.
How many SYNOT Games pokies are in this catalogue?
Boomerang Pokies lists 168 pokies from SYNOT Games for Australia. Book of Secrets is one of them. The provider page holds the rest.
Does it matter that I am in Perth?
No. Perth is named because readers are there. It is not a setting inside Book of Secrets, and it does not change the RTP.
Will I see a bonus figure for Book of Secrets here?
No figure is invented here. If Here2Win Casino shows a welcome offer, it shows it inside the account, with its own terms. Read them there before you opt in.
Is this the same machine I would find in a club?
The page describes the online title from SYNOT Games. It does not claim a venue in Perth.
How do I stop a session on Book of Secrets?
A normal stop is the one you decided in advance. Do not wait for the pokie to look due.
Can you estimate the RTP of Book of Secrets?
The source card did not include a published RTP, so this page leaves the gap empty. Boomerang Pokies will not copy a figure from a similar SYNOT Games pokie.
What is the pros and cons block on Book of Secrets?
It splits what the card publishes from what Boomerang Pokies refuses to invent. A printed RTP is listed because it is a source figure. A missing hit rate is named as a limit, not filled in.
Which part of the Book of Secrets page is the preview?
Start with the short answer under the title, then the fact list. Both should agree: studio SYNOT Games, and RTP only when the card has one. The pros and cons repeat that split in plain lines.
Will a shorter name still open Book of Secrets?
This page is only Book of Secrets. The play button follows that name, not a shorter guess.
What is the maximum win on Book of Secrets?
The card does not publish a maximum win, a reel count, or a payline count. Boomerang Pokies does not guess them.
What features does the Book of Secrets card list?
Expanding Symbols is the whole feature list for Book of Secrets. A label is not a price and not a description of the round.
Stake and the cashier
Leaving for Here2Win Casino is the payment step. Boomerang Pokies does not hold a POLi or PayID balance in between.
The rails are handled after you reach Here2Win Casino. boomerangpokies.com does not take the deposit. The button only hands the session across.
How you open it
- Open Book of Secrets from the play button. The click stays on boomerangpokies.com, then Here2Win Casino loads the pokie.
- Set the stake in A$ before the reels move. A smaller stake just makes a pokie last longer.
- Stop on a clock you set in Perth, not when the pokie 'looks due'.
