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.

StreetPass Mii Plaza
Play Coins can be used in every sub-game in StreetPass Mii Plaza. Their specific uses are listed in the table below.

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.

Pokémon Rumble World
In Pokémon Rumble World, Play Coins can be used at the castle courtyard, which functions as the game's hub world. By spending 10 Play Coins, the player is able to invite three Miis from other players into their courtyard. This feature can be used at no expense once per day.

Super Smash Bros. for Nintendo 3DS
Play Coins are used as the currency of the trophy shop in Super Smash Bros. for Nintendo 3DS, in which the player can purchase collectible trophies of characters. The amount of Play Coins required varies depending on the trophy chosen. The price of a single trophy can be anywhere from 2–100 Play Coins, though the player has the option to pay in Gold instead.
