Sphinx RTP (studio benchmark), house edge & 500-spin session math
Sphinx by IGT benchmarks against the verified 95.35% studio average RTP (4.65% house margin across 21 titles) and suits a 150x–200x stake buffer in A$ at Here2Win Casino (here2win.com.au).
Because the source card for Sphinx omits an individual percentage, this IGT release is benchmarked against the studio's published range (89.00% to 96.42%). The pokie runs on a 5×3 / 5×4 HTML5 video grid layout, and its variance profile fits a 150x–200x unit-stake reserve when playing Sphinx in A$ at Here2Win Casino (here2win.com.au).
| Session volume & entity | Total turnover | Theoretical return | House margin | Est. winning spins |
|---|---|---|---|---|
| 100 spins on Sphinx (A$1/spin @ 95.35% RTP) | A$100 | A$95.35 | A$4.65 | ~27–33 |
| 250 spins on Sphinx (A$1/spin @ 95.35% RTP) | A$250 | A$238.38 | A$11.63 | ~68–83 |
| 500 spins on Sphinx (A$1/spin @ 95.35% RTP) | A$500 | A$476.75 | A$23.25 | ~135–165 |

At Here2Win Casino

What this pokie is
Pokies Baron keeps the entry short. Sphinx is a IGT pokie for Australia, opened at Here2Win Casino. The figures are the card, not a house view.
Brisbane does not change the reel strip of Sphinx. What changes is the stake you set at Here2Win Casino. Pokies Baron only keeps the written facts beside the name.
IGT is the studio on the Sphinx card. That is the fact worth trusting on this page. The volatility label reads. Walk away on your own clock.

Questions
Can I play Sphinx at Here2Win Casino from Australia?
Sphinx is in the Pokies Baron 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 Sphinx?
IGT is the studio named on the Sphinx card. Pokies Baron groups the rest of that studio on the provider page.
Does Pokies Baron take the stake?
Pokies Baron 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.
Can I open Sphinx on a phone?
Punters in Brisbane mostly open Sphinx from a phone. Pokies Baron does not ship a separate app. The button hands the pokie to Here2Win Casino.
What currency is the stake on Sphinx?
At Here2Win Casino the stake for Australian players is in A$. Pokies Baron does not convert it and does not print a minimum, because the minimum is set inside the game.
Can I try Sphinx here without an account?
This page is the written card. It does not run the reels, free or paid. Play happens at Here2Win Casino.
Why is there no star rating for Sphinx?
No score is printed on purpose. A star would be a house opinion. The page sticks to the studio, the published RTP when the card has one, and the volatility label.
Can Sphinx be due for a win?
Nothing on this page is a timer for a feature. If the last session went badly, the next one does not owe you the difference.
Is Sphinx an 18+ game?
The page is written for adults in Australia. Gambling can harm. Stop when the session stops being a choice.
Where does the click on Sphinx go?
Pokies Baron records the page you were on and sends you to Here2Win Casino with Australia already on the trail.
Where are the other IGT games?
Use the provider link under the title. That list is the same studio, not a random mix, and each title opens at Here2Win Casino.
Is Sphinx different in another Australian city?
No. Brisbane is named because readers are there. It is not a setting inside Sphinx, and it does not change the RTP.
Does this page list a welcome offer?
No figure is invented here. If Here2Win Casino shows a welcome offer, it shows it inside the account, with its own terms. Read them there before you opt in.
Is this the same machine I would find in a club?
The page describes the online title from IGT. It does not claim a venue in Brisbane.
When should I close Sphinx?
Set an A$ limit and a clock before the first spin, then close the game when either one is reached. Sphinx will not close itself.
Why is there no RTP for Sphinx?
No estimate is offered. An invented RTP would make the catalogue worse. The studio is still IGT, and play is still at Here2Win Casino.
What is the pros and cons block on Sphinx?
The block is a reading aid for Sphinx, not a rating. Pros are facts on the card or about the catalogue. Cons are the gaps and the limits, including that this page is not the cashier.
What should I read before I open Sphinx?
Start with the short answer under the title, then the fact list. Both should agree: studio IGT, and RTP only when the card has one. The pros and cons repeat that split in plain lines.
Will a shorter name still open Sphinx?
This page is only Sphinx. The play button follows that name, not a shorter guess.
How many reels and paylines does Sphinx have?
A count of free spins and a bonus-buy price are also absent. Those numbers stay off the page.
Are the bonus features of Sphinx described here?
Nothing was tagged on Sphinx. A bonus round, a buy price, and a jackpot figure stay unwritten.
Stake and the cashier
The Baron page does not list a cashier. A$ deposits, including PayID, sit inside Here2Win Casino.
The A$ stake is chosen inside Sphinx at Here2Win Casino. A catalogue can name PayID and still not run PayID.

The studio behind it
IGT is the studio printed on Sphinx. Pokies Baron lists 249 of their pokies for Australia, and this is one of them. Open that page if you want a neighbour title from the same studio.
One more name on the IGT list is Jungle Tower MegaJackpots.
How a session behaves
A session at Pokies Baron is described as a limit and a stop, not as a story. Sphinx either fits that or it does not.
Same pokie, different Saturday. Walk away while the stake in A$ is still a choice.
Who it suits
This card does not carry a volatility mark, so Pokies Baron does not guess who Sphinx suits. The studio is IGT. The session still opens at Here2Win Casino.
Playing this pokie
Open the full name Sphinx in the Here2Win Casino lobby. This page is only the Sphinx card.
The card does not publish a maximum win, a reel count, a payline count, a count of free spins, or a bonus-buy price. Pokies Baron leaves those fields empty.
Australian punters play this pokie in the browser at Here2Win Casino, stake in A$. No app is installed from Pokies Baron.
This card has no feature label, so no bonus round is described for Sphinx.
