As long as everybody has a Nintendo 3DS family system, friends can play together in multiplayer modes in supported titles.

Some software requires each player to own a copy of the title, but many Nintendo 3DS games feature Download Play, enabling wireless multiplayer activities even when only one player has a Game Card. The back of each retail game box displays the number of players the game supports and if the game can be played via Download Play.
It's also possible to play certain titles with other players online via Nintendo Network.
