At the start of the game, the contestant is shown a wrong price for the first prize and is asked to guess whether its actual price is "more" (higher) or "less" (lower) than the one displayed. If correct, the contestant wins that prize. This is repeated for the subsequent prizes, including the car. Stumble once at any point it's game over, but the contestant gets to keep any of the prizes won up to that point.
- More or Less was the last pricing game to premiere during Bob Barker's tenure as host of the show. The game was created by Barker himself.
- Bob Barker had a contestant win all 4 prizes in this game on the 2nd playing from February 21, 2007 (#3893K) and it was the only time that it's happened during Bob's tenure. All the other wins occurred after Drew Carey took over.
- Under Bob's tenure, after Rich Fields announces the first three prizes, it would cut to Bob talking with the contestant, and after that the car was described. But, in the Carey era, the announcer will describe the first three prizes and straight to the car.
- On February 19, 2016 (#7415K, aired out of order on February 16), during Dream Car Week, a Maserati was offered. During that playing, the contestant lost on the second prize.
- More or Less has officially received 23 wins over the years.
- It has been lost on the first prize 14 times; that means the contestant has won absolutely nothing.
- As with Golden Road, the contestant is allowed to keep playing as long as they guess correctly. Except Golden Road has you choose which number of 2, 3, or 4 is the correct number for the prize; in this game you have a 50-50 chance to win up to 4 prizes.
- Like Magic Number and Gas Money, this game has never been the first pricing game to start any show. Because the electronic component of the game needs time to start up, the game can be no earlier than 2nd on the show.
- The most number of times this game was played in any season was 16.
