Bonus Game

Bonus Game debuted on September 4, 1972 and was the second pricing game ever played on The Price is Right. Paul, the first contestant to play this game, wound up winning the showcase on the first episode with a difference of only $4. In 2014, Home and Garden Magazine rated this the second best performance on a debut episode of a game show behind, ironically, the debut episode of Power of 10, hosted by future Price is Right host Drew Carey.
The game is played exactly the same as Shell Game except only the prize with the bonus behind it matters, ensuring that the producers can determine the difficulty of the game corresponding to whether or not they want the prize given away.
