Until 1981, during the Money Cards, a "double" (or having the next card be the same value as the previous one) used to lose the contestant money. Enough contestants cried foul, and eventually it became a push. This carried over to the Bob Eubanks edition as well.
Two $500 bonuses were added to the main game by 1981. One for if a contestant hits the actual number in a question right on, and one for if a contestant can run his line of cards to the end without freezing or guessing wrong.
Only one contestant won the maximum $28,800 allowed in Jim Perry's version, Norma Brown in late-1978. No contestant won the max $32,000 offered in the CBS and syndicated versions, although a few contestants came close.
The intro of the Jim Perry version (1978-81) actually featured clips from the pilot. If you pay close attention to the wide shot of the set, you may notice a slightly different layout and design for the "Money Cards" bonus round board.
Beginning on September 29 and October 27, 1986, the CBS and syndicated versions added a second bonus round game in which the contestant could win a car, respectively. The game followed the Money Cards, and featured a row of seven playing cards, aligned in a horizontal row. Correctly choosing the card marked "CAR" won the car for a contestant. Contestants got one pick (from winning the game), but could win additional picks by finding a "JOKER" during the Money Cards. On July 4, 1988, a new car game debuted, in which the contestant had to correctly guess how many of the audience's "special group" of members responded to a question (out of 10 members). Guessing the correct number on the nose won the car, with special cash bonuses for being a certain number off, high-or-low.
On the CBS and syndicated versions, they featured two new varieties of questions in addition to the traditional survey questions: Beginning on July 7, 1986, the audience poll was a question asked of a group of studio audience members (usually 10 members) selected for a shared characteristic such as gender or occupation. If a contestant guessed the exact number of audience members who made a certain response to one of these questions, he or she won a $100 bonus and the poll group was given $100 to share. The same poll group was used for a week's worth of episodes. Introduced on October 6, 1986, the educated guess questions were general knowledge trivia questions which had numerical answers. Exact guesses won a $500 bonus for the contestant. Guesses and responses were originally registered on the displays; this later changed to the guesses and responses superimposed on the displays, as they could be more than 99, which was the highest number the displays could register.
The tiebreaker game had two versions on NBC and CBS, each with three cards dealt instead of five, with a maximum of three questions, and until March 29, 1988, until the series' ending, involved only one question, played in a sudden death mode.
When a contestant won a car, a graphic of chasing rainbow cars would be shown around the contestant. Though in the first week, the rainbow "CAR" word chase didn't appear, until the third week in the show's run (similar to the rainbow "CAR" chase on Classic Concentration (1987)). The most coincidental thing is both game shows were produced by Mark Goodson, they both aired, within a year, at the same time on different networks.
When the CBS show was in development, auditions were held for people to host the show. For daytime, Bruce Forsyth was originally considered to host the show, but he was already hosting Hot Streak (1986), at the time, and former host, Jim Perry was considered, but was still hosting Sale of the Century (1983), at the time. The job went to Bob Eubanks, instead. For nighttime, Rich Fields, was originally considered for the hosting position, he turned it down, as well as Bob Eubanks, but was very busy hosting The New Newlywed Game (1984), therefore, the job was given to Bill Rafferty, who later hosted the short-lived revival of Blockbusters (1987) on NBC.
Both Jim Perry and Bob Eubanks were the only two emcees to use microphones during their own run. On the NBC version, Perry used a wired microphone with a marble top, on the CBS version, Eubanks used a Sennheiser microphone.
On the NBC version, each time a player freezes their own position, the player's bracket or freeze bar connected to his/her name electronically moved by itself. Sometimes, the freeze bar is broken and when that happened, a handheld freeze bar was placed on the new base card. On the CBS version, manual freeze bars were maneuvered.
During the first ten months on CBS, Bob Eubanks would ask on average no more than eight questions per show. Jim Perry, who hosted the NBC version, would ask as many as ten, maybe eleven questions. It may be inferred that the reason for fewer questions on the CBS version is because of Eubanks and the contestants consuming unnecessary time for interaction.
Originally, when the show returned on CBS, when a contestant won his/her game and/or match, there were no "X" indicators on the podium, in front of the contestant, until February 3, 1986, indicating who won a game and the frame lights are always lit.
