Take charge as one of many mayors in Happiest Town (ハピエストタウン) to build buildings and attempt to make your city the happiest of all. The game includes more than forty types of buildings, and in the game you earn money, build stuff, earn more money from what you've built, and score at the end of the game with your city's happiness being determined by a "population x happiness" formula.
