The player's uncle is unable to take care of his farm anymore, so he hands over the responsibility of caring for the farm to the player. The game starts with a scarecrow giving the player a farming tutorial. By selling crops/products, the player earns coins which can be used to buy production buildings, pets and decoration items. By doing so, they also earn experience points (XP), with which they level up. As they progress, the player is eventually introduced to Angus, a friend of the player's uncle who gives a fishing tutorial. Earlier on, the player is also introduced to an NPC named Greg, who arrives at the player's farm requesting items, or puts items in his "roadside shop" which players can buy.
Players form into small "neighborhoods", in which the members can assist each other when in need (for example, by requesting multiple items) and can also chat with one another. Players can also trade their goods with the other friends or neighbors from the neighbourhood.
