Double Rainbow for Australia, Boomerang Pokies
Australian punters can open the session page for Double Rainbow pokie apart from this catalogue.

What this pokie is
Boomerang Pokies sends you out and back: read Double Rainbow 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.
If 96.38% is the figure you came for, it is printed above and in the fact list. Do not average one short session against a published RTP.
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.
The Hacksaw Gaming page also names Cash Compass.

More from Hacksaw Gaming
Who it suits
A medium-volatility pokie sits in the middle of the pack for pace. Double Rainbow is an ordinary session game at Here2Win Casino, not a system.
How a session behaves
Coming back to Double Rainbow later does not make it due. Keep the A$ stake where you left the rule.
A normal session on Double Rainbow is a run of spins you can afford to lose, not a plan to clear a welcome offer. Any match lives inside the Here2Win Casino account.
Questions
Does Here2Win Casino list Double Rainbow for Australian punters?
Double Rainbow 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.
What return does Double Rainbow publish?
The published RTP of Double Rainbow is 96.38%. That is a long-run studio figure. A single session in Brisbane can finish far from it.
What does the volatility label on Double Rainbow mean?
Double Rainbow is marked medium-volatility. On a medium-volatility pokie the balance usually moves in lumps, so the stake in A$ matters more than the theme.
What provider is behind Double Rainbow?
The provider is Hacksaw Gaming. Other Hacksaw Gaming pokies on Boomerang Pokies sit on the same provider page if you want a neighbour title.
Where does the A$ stake actually go?
Boomerang Pokies 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 Double Rainbow on a phone?
Yes. The play button on boomerangpokies.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$.
What currency is the stake on Double Rainbow?
You choose the A$ stake after Here2Win Casino loads Double Rainbow. This catalogue page never takes the money.
Is there a demo of Double Rainbow on this page?
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 Double Rainbow?
Double Rainbow is not ranked against other pokies on Boomerang Pokies. Use the figures on the card, not a badge.
Does Double Rainbow remember my last session?
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.
How old do I have to be to play Double Rainbow?
The page is written for adults in Australia. Gambling can harm. Stop when the session stops being a choice.
Where does the click on Double Rainbow go?
The click stays on boomerangpokies.com first, then opens Double Rainbow at Here2Win Casino. The partner address is not printed in the article.
How many Hacksaw Gaming pokies are in this catalogue?
Use the provider link under the title. That list is the same studio, not a random mix, and each title opens at Here2Win Casino.
Does it matter that I am in Brisbane?
No. Brisbane is named because readers are there. It is not a setting inside Double Rainbow, 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 Double Rainbow a club or pub pokie?
No. Double Rainbow on Boomerang Pokies is an online pokie opened at Here2Win Casino. It is not a machine on a club floor and it does not carry a local sticker.
How do I stop a session on Double Rainbow?
A normal stop is the one you decided in advance. Do not wait for the pokie to look due.
Why does Double Rainbow have a pros and cons list?
The block is a reading aid for Double Rainbow, 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 Double Rainbow?
Start with the short answer under the title, then the fact list. Both should agree: studio Hacksaw Gaming, and RTP only when the card has one. The pros and cons repeat that split in plain lines.
Will a shorter name still open Double Rainbow?
Use the full name on this card. A shorter search in the Here2Win Casino lobby can open a different Hacksaw Gaming title.
How many reels and paylines does Double Rainbow have?
A count of free spins and a bonus-buy price are also absent. Those numbers stay off the page.
What features does the Double Rainbow card list?
Bonus Buy and Multiplier Wilds is the whole feature list for Double Rainbow. 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.
PayID, POLi and the usual cards are named because Australian punters ask about them. boomerangpokies.com does not take the deposit. The button only hands the session across.
How you open it
- Open Double Rainbow 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 medium-volatility pokie last longer.
- Stop on a clock you set in Brisbane, not when the pokie 'looks due'.
