Keep building increasingly more houses/retailers literally the moment you receive the cash and experience level on their behalf. Retailers don't take lengthy to pay for huge sums of cash in early stages within the game. Earn additional XP and coins by completeing quests. To determine the quests menu to begin finishing some yourself, tap around the icon towards the left from the screen. Bear in mind that it's not necessary to purchase land that's directly linked to land that you simply already own. Regardless of the next place is you can explore (like a cave or perhaps a tower), you can purchase land right alongside it. You'll be able to expand towards the land using the artifact onto it, and explore it, without needing to be worried about possessing the whole island. Rubies do cost real cash to get, and aren't free. Only spend Rubies if you think comfortable doing this, and when you realize that they'll simply be acquired by investing real cash.
