2v2 Mode

2v2 Mode is a mode of playing Uno that is present in Uno Mobile and the console version of Uno, most prominently, but can also be played with physical cards. The mode involves four players that are split into two teams of two players each, and team members sit across from each other. As soon as one teammate has discarded all of his or her cards, that round ends and both that teammate and his/her partner win the round. The video game versions of Uno mentioned above both allow teammates to see each other's cards, but this is not possible to do with physical cards without making it extremely easy for opposing teams to see each other's cards as well, therefore ruining the game.
