Uno rules state that:
If a player plays a wrong card and it is noticed by any other player, he/she must take the card back and take two extra cards from the DRAW pile. Play continues with the next player in turn.
As I understand it, this penalty applies when a player plays a wrong card during HER turn. What about when a player plays a VALID card OUT of her turn because she thought it was her turn to play?
How do you interpret this penalty?
