Play Coins

Play Coins are a form of in-game currency developed for the Nintendo 3DS. While all sub-games in StreetPass Mii Plaza are centered around Play Coins, the currency is also usable in applications such as Swapnote and AR Games as well as in certain 3DS titles. Walking 100 steps while the console is in sleep mode earns the player a single Play Coin, and a maximum of 10 can be collected each day. The maximum amount of Play Coins that a player can have at a time is 300.

Tomodachi Life

In Tomodachi Life, Play Coins are used to purchase special foods from traveler Miis at an island's campground. These foods, which range from 1–5 Play Coins in price, can be bought once the player solves a traveler's problem by giving them the item that they require. A traveler will give the player a special food for free if they have come to the island to visit their parents.
