Session math & RTP benchmark
Book of Ishtar does not carry an individual published RTP on its source sheet, so no single-title percentage is guessed. Across the 26 Holle Games titles that do publish a return in this catalogue, the studio average is 95.43% (ranging from 92.40% to 96.23%). 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$95.43 | A$4.57 | ~27–33 |
| 250 spins (A$1/spin) | A$250 | A$238.57 | A$11.42 | ~68–83 |
| 500 spins (A$1/spin) | A$500 | A$477.15 | A$22.85 | ~135–165 |
Pros and cons

- The page will not borrow a pace label from another Holle Games pokie.
The studio behind it
If you only needed the maker, it is Holle Games. Pokies Vault does not swap the studio for a local name. The provider page is the clean list.

What this pokie is
Pokies Vault files Book of Ishtar as a record: studio Holle Games, then the numbers the card actually has, then the door to Here2Win Casino. Guessing would break the point of the page.
Book of Ishtar is the Holle Games pokie Pokies Vault writes up for punters who open it at Here2Win Casino. The card is the source of the figures.
The preview under the title is the short form of this card. The description tag repeats that sentence. A missing RTP stays missing there too.
How you open it
- Open Book of Ishtar 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
Does Here2Win Casino list Book of Ishtar for Australian punters?
Yes. Pokies Vault links Book of Ishtar to Here2Win Casino for Australian players. The button on this page stays on pokiesvault.com and then opens the pokie at Here2Win Casino.
Which studio built Book of Ishtar?
Holle Games is the studio named on the Book of Ishtar card. Pokies Vault groups the rest of that studio on the provider page.
Does Pokies Vault take the stake?
You are reading a catalogue page. Deposits, PayID and the spin itself belong to the Here2Win Casino account, not to pokiesvault.com.
Can I open Book of Ishtar on a phone?
Punters in Perth mostly open Book of Ishtar from a phone. Pokies Vault does not ship a separate app. The button hands the pokie to Here2Win Casino.
What currency is the stake on Book of Ishtar?
You choose the A$ stake after Here2Win Casino loads Book of Ishtar. This catalogue page never takes the money.
Is there a demo of Book of Ishtar on this page?
This page is the written card. It does not run the reels, free or paid. Play happens at Here2Win Casino.
Does Pokies Vault score Book of Ishtar?
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 Ishtar remember my last session?
No. Book of Ishtar 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 Ishtar an 18+ game?
The page is written for adults in Australia. Gambling can harm. Stop when the session stops being a choice.
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 Holle Games games?
Pokies Vault lists 55 pokies from Holle Games for Australia. Book of Ishtar is one of them. The provider page holds the rest.
Is Book of Ishtar different in another Australian city?
No. Perth is named because readers are there. It is not a setting inside Book of Ishtar, 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 Holle Games. It does not claim a venue in Perth.
When should I close Book of Ishtar?
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 Ishtar?
The source card did not include a published RTP, so this page leaves the gap empty. Pokies Vault will not copy a figure from a similar Holle Games pokie.
What is the pros and cons block on Book of Ishtar?
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 Ishtar?
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 Ishtar?
Use the full name on this card. A shorter search in the Here2Win Casino lobby can open a different Holle Games title.
What is the maximum win on Book of Ishtar?
A count of free spins and a bonus-buy price are also absent. Those numbers stay off the page.
What features does the Book of Ishtar card list?
The labels are Expanding Symbols. They are names only. This page does not add a bonus amount, a free-spin count, or a jackpot figure.
How a session behaves
Use the figures first and the mood never. Book of Ishtar at Here2Win Casino is still only a session with an A$ stake.
Book of Ishtar has no memory of last night. Stop on a clock. A published RTP, when the card has one, is a long sample, not one arvo.
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. The button only hands the session across.
Who it suits
This card does not carry a volatility mark, so Pokies Vault does not guess who Book of Ishtar suits. The studio is Holle Games. The session still opens at Here2Win Casino.
