One price for everybody
The curve on this page is the price, in rupiah and in dollars alike. No quiet discount for friends, and no negotiation that leaves another buyer paying more for the same amount.

We write when we open
People on the list are invited first, before this page becomes a shop. Handover happens inside Kathana, to the character you name.
This Rupiah has somewhere to be.
Kathana is not a number on our screen. It is the world the Rupiah gets spent in, and where we hand it over, to the character you name yourself.
Our own illustrations, not the game's official art.
What we promise, and what we do not.
Nothing is for sale today
If somebody is offering Kathana Rupiah in our name right now, it is not us. This page is only collecting a waiting list.
The price is not locked yet
The curve may change before we open, and the dollar price moves with the exchange rate. Whatever you saw when you signed up is stored exactly as it was, rate included.
Handover inside Kathana
Rupiah goes to the character you name, in the same world you spend it in. No third party in the middle.

The questions that always come up.
What is Kathana, and what is Rupiah?
Kathana is a Tantra Online Classic world. Rupiah is the currency inside it, not the real-world Indonesian rupiah. What you pay with real money is our work putting it in your character’s hands.
Why does the price fall on larger orders?
Handling one large order costs us about what a small one does. The difference goes back into the price rather than into our pocket.
Which part of the order gets the curve price?
All of it, not just the last million. If the curve gives $0.639 at 100 million, the whole hundred million is priced at $0.639 per million.
Why are there no tiers?
Because tiers make the person who stops one million short of a line pay more per million than their neighbour. A smooth curve has no line to game.
Where does the dollar price come from?
One rupiah price divided by the daily exchange rate, not a second price list. We fetch the rate automatically several times a day, so the dollar figure drifts a little day to day. If the rate source is having trouble, this page tells you which rate it is using.
If I sign up, is my price locked?
Not yet. The curve can still change before we open. What we store is the figure you saw when you signed up, together with the rate behind it, so you have something to check against rather than a memory.
What if I change my mind?
Nothing is paid at this stage, so there is nothing to cancel. Reply to our email and we delete your details.
