Puzzle Swap

About

Puzzle Swap is a game in which players aim to complete a 3D animated picture of a Nintendo video game by gathering its pieces. If a player encountered on StreetPass possesses any pieces the player does not have, the player can choose one of their pieces to add to their own. The player may also use Play Coins to buy random pieces for their existing panels, although it won't always be a new piece. After the December 2011 update, new puzzles became available which included four or eight pink squares in the center. Pink pieces are distributed to players via SpotPass and can only be gathered via StreetPass; they cannot be bought using Play Coins. Some puzzles have more pieces than others, making them harder to complete.
