How to play UNO Teams: First, team up with a partner. The basic gameplay is similar to classic UNO - match colors, numbers, or symbols. Special cards such as Wild Team Play and Wild Team Draw 4 can help your team win. If you play a card with a pass symbol, you can give a card of your choice to your partner. When one teammate finishes all their cards, they take half of the other teammate's cards and continue playing. Note: When you or your partner are left with only one card, you must yell 'UNO!' to let others know. Maintenance: Keep the cards in a dry place to prevent them from getting damaged. Make sure to shuffle the cards well before each game to ensure fairness.
