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$20.05 | ~135–165 |
Pros and cons
Pros
- The studio is named: SYNOT Games.
- Stake for Australian punters is in A$ at Here2Win Casino.
- The rest of SYNOT Games is one provider page away.
Cons
- This page is a catalogue. It does not hold an A$ balance.
- A match amount is not a fact of the Book of Secrets card.
- The return gap is left empty on purpose.
- Volatility is not on the source card.

What this pokie is
Pokies Vault files Book of Secrets as a record: studio SYNOT Games, then the numbers the card actually has, then the door to Here2Win Casino. Guessing would break the point of the page.
Perth does not change the reel strip of Book of Secrets. City is not a setting in the game. Pokies Vault only keeps the written facts beside the name.
Before the first spin, use the fact list and the pros and cons. Neither one adds a star rating. Book of Secrets is the SYNOT Games pokie, and the reels run at Here2Win Casino.
How you open it
- Open Book of Secrets from the play button. The click stays on pokiesvault.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'.
Questions
Where do I open Book of Secrets if I am in Australia?
Book of Secrets is in the Pokies Vault 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?
The provider is SYNOT Games. Other SYNOT Games pokies on Pokies Vault sit on the same provider page if you want a neighbour title.
Does Pokies Vault take the stake?
Pokies Vault is a catalogue. The stake in A$ is placed at Here2Win Casino after you follow the play button. This page does not hold a balance.
Does Book of Secrets work on mobile in Australia?
Punters in Perth mostly open Book of Secrets from a phone. Pokies Vault does not ship a separate app. The button hands the pokie to Here2Win Casino.
Is Book of Secrets staked in A$?
You choose the A$ stake after Here2Win Casino loads Book of Secrets. This catalogue page never takes the money.
Can I try Book of Secrets here without an account?
This page is the written card. It does not run the reels, free or paid. Play happens at Here2Win Casino.
Why is there no star rating for 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.
How old do I have to be to play Book of Secrets?
18+. Pokies Vault 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?
Pokies Vault records the page you were on and sends you to Here2Win Casino with Australia already on the trail.
Where are the other SYNOT Games games?
Pokies Vault 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.
Does this page list a welcome offer?
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?
Set an A$ limit and a clock before the first spin, then close the game when either one is reached. Book of Secrets will not close itself.
Why is there no RTP for Book of Secrets?
No estimate is offered. An invented RTP would make the catalogue worse. The studio is still SYNOT Games, and play is still at Here2Win Casino.
Why does Book of Secrets have a pros and cons list?
It splits what the card publishes from what Pokies Vault 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.
What should I read before I open Book of Secrets?
The preview is the same card, shortened. It is not a tip and it does not know how your session in Perth will finish.
How do I open the right Book of Secrets?
Use the full name on this card. A shorter search in the Here2Win Casino lobby can open a different SYNOT Games title.
How many reels and paylines does Book of Secrets have?
The card does not publish a maximum win, a reel count, or a payline count. Pokies Vault does not guess them.
Which feature labels are on Book of Secrets?
Expanding Symbols is the whole feature list for Book of Secrets. A label is not a price and not a description of the round.
How a session behaves
Use the figures first and the mood never. Book of Secrets at Here2Win Casino is still only a session with an A$ stake.
Same pokie, different Saturday. Walk away while the stake in A$ is still a choice.
Stake and the cashier
The vault does not store deposits. PayID and cards are a Here2Win Casino matter once pokiesvault.com has handed you over.
PayID, POLi and the usual cards are named because Australian punters ask about them. pokiesvault.com does not take the deposit. This page never opens a cashier.
Who it suits
This card does not carry a volatility mark, so Pokies Vault does not guess who Book of Secrets suits. The studio is SYNOT Games. The session still opens at Here2Win Casino.
