Question: can you put 2 of the same cards down in uno?
Answer: You can not play two cards on one turn. So if it is your turn, and you have two cards left, then before you place one of the cards down you need to say "Uno." Then you are left with one card, which you will play (if possible) on your next turn. ... By extension, if you have identical cards you can play both in the same go.
