Just a technicality..... But, there is no way to time out in this game. It is set up that you have a default guess no matter what. So, you technically have 2 days to "change" your guess, and by not optioning to make a change, your default guess is always used. On the first turn, you default guess is 0, after the first turn it is whatever your previous guess was.
