Three on-stage contestants, two new challengers and one returning champion, were each given one point at the outset of the game, indicated by diamonds on the front of their podiums.

Encircling the contestants' podiums was an electronic wheel with digits 0–9, blank spaces, and a car symbol.

Answer: Tip O'Neill, who was serving as Speaker of the United States House of Representatives at the time.)

If neither opponent guessed correctly, the contestant who selected the riddle won $50 and spun the wheel, but did not score any points.

Later, a single plate was used, with previous incorrect digits automatically eliminated from each subsequent attempt.

Prior to the first episode, postcards were obtained via an ad in TV Guide; during the show's run, viewers with telephone numbers whose last four digits appeared on the main game board were eligible to send in cards.

If the contestant won the bonus game on any day from Monday through Thursday, the home viewer received an additional $1,000; a Friday win awarded $5,000 more.

After the series was canceled, 15 home viewers won $1,000 each in a random drawing from the unused postcards.
