The rules regarding clue-giving were the same as on all previous versions of "Password", with the exception of two instances exclusive to "Password Plus". Beginning with the April 23, 1979 episode and continuing until the series' end in 1982, two rules were put into place. The first disallowed any password's direct opposite, or antonym, as a legal clue (such as "loose" for "tight"). The second expanded a penalty already present in the game. When the series began, if the clue-giver given the option to play or pass did not decide in time or failed to give a clue, the other team's clue-giver was allowed to give two clues to his/her partner. After the change, the two-clue penalty was extended to any time a clue-giver failed to give a clue in time. In all cases, the two clues had to be given separately, with one guess at the password after each.
