The only change I recall is that instead of the contestants trying to be first to ring in and answer a "double meaning," question, Art James started with the contestant at the furthest left, asking a general knowledge question. If that "challenger," answered correctly, he/she would try to guess the "Checkwriter's" selection of number. If correct, that "challenger," switched places with the checkwriter. Play then proceeded to the player on the immediate right (thus, from the upper row), and continued until somebody successfully wrote a four-digit check.
The bonus round was then played, and afterwards, the traditional "double meaning," toss-up question was used only to determine a new checkwriter.
