Pros and cons
Pros
- The studio is named: KA Gaming.
- Stake for Australian punters is in A$ at Here2Win Casino.
- The page keeps the studio figure 96.00% and does not round it.
- Volatility is marked very-high volatility.
Cons
- This page is a catalogue. It does not hold an A$ balance.
- No bonus figure is printed. Any offer sits inside Here2Win Casino and can change.
- A short session can sit a long way from the published return.
The studio behind it
If you only needed the maker, it is KA Gaming. Here2Win Casino does not rebadge the game. The provider page is the clean list.
KA Gaming also has Alien Tour on this list, with Angry Piggies further along.

What this pokie is
Pokies Vault files Bubble Double as a record: studio KA Gaming, then the numbers the card actually has, then the door to Here2Win Casino. Guessing would break the point of the page.
Before the first spin, use the fact list and the pros and cons. Both stay inside what the card publishes. Bubble Double is the KA Gaming pokie, and the reels run at Here2Win Casino.
Same pokie, different night. What changes is your stake and when you stop. Pokies Vault keeps the written facts in one place so the Here2Win Casino lobby is not the only page that names the game.
Fruits is the theme printed here, and 100 HOT SLOT uses that same tag.
How you open it
- Open Bubble Double 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 very-high volatility pokie last longer.
- Stop on a clock you set in Melbourne, not when the pokie 'looks due'.
Questions
Does Here2Win Casino list Bubble Double for Australian punters?
Yes. Pokies Vault links Bubble Double to Here2Win Casino for Australian players. The button on this page stays on pokiesvault.com and then opens the pokie at Here2Win Casino.
Is the RTP of Bubble Double on this page?
96.00% is the RTP printed for Bubble Double. Pokies Vault does not adjust that number and does not promise it over one visit to Here2Win Casino.
Is Bubble Double a high variance pokie?
The card says very-high volatility. That describes the spread of results, not how often a feature 'should' hit on a Tuesday night.
Which studio built Bubble Double?
The provider is KA Gaming. Other KA Gaming pokies on Pokies Vault sit on the same provider page if you want a neighbour title.
Where does the A$ stake actually go?
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 Bubble Double work on mobile in Australia?
Yes. The play button on pokiesvault.com is the same on a phone as on a desktop. The session then runs at Here2Win Casino, and the stake is still in A$.
What currency is the stake on Bubble Double?
At Here2Win Casino the stake for Australian players is in A$. Pokies Vault does not convert it and does not print a minimum, because the minimum is set inside the game.
Can I try Bubble Double here without an account?
No. Pokies Vault does not embed a demo of Bubble Double. The button opens the pokie at Here2Win Casino. Any practice mode, if one exists, is inside that account, not on pokiesvault.com.
Why is there no star rating for Bubble Double?
Bubble Double is not ranked against other pokies on Pokies Vault. Use the figures on the card, not a badge.
Can Bubble Double 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 Bubble Double 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 KA Gaming games?
Pokies Vault lists 847 pokies from KA Gaming for Australia. Bubble Double is one of them. The provider page holds the rest.
Is Bubble Double different in another Australian city?
No. Melbourne is named because readers are there. It is not a setting inside Bubble Double, and it does not change the RTP.
Will I see a bonus figure for Bubble Double here?
Pokies Vault will not print a match amount or a spin count for Bubble Double. Those terms belong to the casino, and they change.
Is Bubble Double a club or pub pokie?
The page describes the online title from KA Gaming. It does not claim a venue in Melbourne.
How do I stop a session on Bubble Double?
Set an A$ limit and a clock before the first spin, then close the game when either one is reached. Bubble Double will not close itself.
Is the hit ratio the same as the RTP?
The hit ratio on the card is how often a spin returns something, not how much it returns. It is not the RTP, and it is not a promise for the next hour.
Why does Bubble Double have a pros and cons list?
The block is a reading aid for Bubble Double, 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.
Which part of the Bubble Double page is the preview?
The preview is the same card, shortened. It is not a tip and it does not know how your session in Melbourne will finish.
How do I open the right Bubble Double?
This page is only Bubble Double. The play button follows that name, not a shorter guess.
How many reels and paylines does Bubble Double 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 Bubble Double described here?
Nothing was tagged on Bubble Double. A bonus round, a buy price, and a jackpot figure stay unwritten.
How a session behaves
Use the figures first and the mood never. Bubble Double 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.
The A$ stake is chosen inside Bubble Double at Here2Win Casino. Funding the account is a separate step from reading Pokies Vault.
Who it suits
A very-high volatility pokie suits a short session with a small A$ stake. The balance tends to move in lumps, so Bubble Double is a poor place to try to win a loss back.
