Puzzle Swap
Puzzle Swap is a small game included in the built-in StreetPass Mii Plaza app that comes with the Nintendo 3DS. It uses the system's StreetPass technology to find nearby 3DS consoles and exchange pieces between the two, offering the choice of one new (if available) puzzle piece from the other's collection. Random puzzle pieces can also be purchased at two 3DS Play Coins a piece.
Initially the game included 7 unique puzzles, though as a part of the December 2011 3DS update Puzzle Swap was updated with 7 additional puzzles, along with the abillity for Nintendo to periodically send out more through SpotPass. The original puzzles were made up of 15 separate pieces, but the number has increased post-launch to offer up 24-piece and 40-piece puzzles.
Each puzzle is made up of common pieces and special/rare pink pieces. These pink pieces cannot be obtained via Play Coins, but are instead put into StreetPass circulation via special Nintendo events, Nintendo "staff" characters, and given to new players upon starting Puzzle Swap.
