Ping Pals

Items can be unlocked by trading with other players or buying them in a shop. Players must trade to complete their collections, as each cartridge's shop offers a different subset of the items.

Players receive a regular allowance of coins, using the DS' date-keeping functionality, and can get more by playing mini-games (such as Guess the Number and Hot Potato), typing certain secret words in chat (each word works once per file) and even for choosing to display the credits screen more than once.

Although Ping Pals was marketed as a nonviolent, girl-friendly game, it was frequently criticized as not being interactive enough to be called a game. In addition to this, the DS has a built-in chat program called PictoChat. PictoChat includes features that Ping Pals lacks, and due to this, the game received "generally unfavorable reviews" according to the review aggregation website Metacritic. For instance, Nintendo Official Magazine, in its Nintendo DS special, opened their review of the game by describing its existence as being "a bit like paying money to breathe air." By contrast with other summaries in the magazine, which were typed and more detailed, the reviewer gave a one word summary, handwritten in PictoChat, reading "POINTLESS".

Several images in Ping Pals were licensed from QPlay. These include the Cupimon, a green creature that dances in the startup animation, and several avatar and clothing graphics.
