You don't need to pay for it, Its free to play. Paying for it is just an option you can do like giving tips to people for their work. If I had the money I would totally tip them but I don't so until I get the money I wont. Now I'm American so I don't know how you get would take your currency and make an equivalent for our U.S. currency the only advice I can give is see if you can download it for free or try to Google the U.S. ratio you need to get it in your currency. Sorry if this doesn't help you.
