This is a list of WFC compatible games on the Nintendo DS and Nintendo DSi handheld game consoles. These games are playable online out of the box, as long as the system is in range of a properly-configured WiFi router or a Nintendo Wi-Fi USB Connector, and are not to be confused with games that only allow for wireless multi-play within a close physical vicinity (ad-hoc).
After Nintendo's termination of the free Nintendo Wi-Fi Connection service on May 20, 2014, the majority of the game titles remain virtually playable, but their online connectivity and functionality are rendered defunct, even after some of them were re-released digitally. However, some online games can still be played on community-run servers.
