A five-letter word was displayed, with a plus sign at the left end and a minus sign at the right. The host read a toss-up clue whose answer differed from the displayed word by one letter. The change that needed to be made was displayed when a contestant buzzed-in. If a letter was highlighted, it needed to be changed. The plus and minus signs indicated that a letter had to be added or removed, respectively, without changing the order of the others. Answers could be three, four, or five letters in length.
