UNO Teams retains the core gameplay of the classic UNO card game but introduces a team-based format where players compete in pairs. The set includes special cards like Wild Team Play and Wild Team Draw 4, designed to help teammates collaborate for victory. When a player uses a card marked with a "pass" symbol, they can transfer a card of their choice to their partner. If one teammate runs out of cards, they take half of their partner’s remaining hand and continue playing. As in standard UNO, players—or their teammate—must call out "UNO!" when down to their last card. The game is designed for 2–10 players, ages 7 and up.
