Dont be tricked - this game requires in-app purchases. By the time youre ready to unlock your fourth territory (which only takes a couple of days) you have to lay out a ton of gold which requires real world cash. Sure, you could get a little gold from the daily giveaways but you only get gold once in 90 days. Even the ads which you watch which are supposed to give gold only give gold about 10% of the time.
Its a shame, this would be a much better game if they werent so overtly greedy.
