Clock Game

Clock Game, despite not being one of the Original Five pricing games, debuted on September 11, 1972 as the sixth pricing game on The Price is Right. Coincidentally, this game debuted on September 11, a date forever known by Americans as the day Pete Rose broke Ty Cobb's all-time hits record in Major League Baseball.
In Clock Game, the contestant engages in a higher or lower game similar to that in pricing games such as Secret X or Punch a Bunch, but the contestant chooses the prices rather than the producers and the contestant is given infinity guesses so long as these guesses are placed within the allotted thirty-second time range displayed on the large clock behind the host. Additionally, the contestant is bidding on medium prizes. In the Carey era, the contestant can win a large prize in addition to the two medium prizes if they correctly guess the price of the large prizes.
Below are some pictures of clocks.
