===Secret Square===
The Secret Square game is played as the first game on a given broadcast (or the first complete game, if a show began with a game already in progress) during the daytime series. In this game, a randomly selected Secret Square is shown only to the home audience by the shot of the television camera. A contestant who picked that square during the game won a bonus prize package if they correctly agreed or disagreed with the star. Secret Square prize packages added cash on the daytime edition, which started at around $1,000 for the 1966 episodes; the base amount increased in the later years from 1967 to 1980, by which time a new Secret Square package was worth around $3,500 to $4,500. The package grew daily until won. The question for the star was sealed in a special envelope and was almost always multiple-choice.

For the 1968 NBC primetime series, the first two games were the Secret Square games. One Secret Square offered a trip and the other Secret Square offered a car or occasionally a boat. If not won, the prize offered in the first round carried over to the second round, with a second prize added. If not won in the second round, the Secret Square prize package went unclaimed.

During the first two seasons of the syndicated series (1971–1973), the first two games were Secret Square games, with the prize packages generally worth about $2,500. If no one claimed the prizes offered in the first round, they were carried over to the second round, and if still not won went unclaimed. Beginning in 1973 and ending in 1978, the first three games had a Secret Square, with each game offering different prize packages, usually worth between $2,000 and $7,000. From 1978 to 1980, the Secret Square games were cut to game numbers two and three (the first two games early on). The Secret Square was not used during the 1980–1981 daily syndicated version.
