On TJW's kids weeks, the main game was played for points instead of dollars, leading to two things that I hated. First, the winner got a $500 savings bond, which only cost them $375. Second, it was a flat $500; that is, if they won with a score of 550, they didn't get a $50 savings bond in addition.
I don't see why it upsets you that a game show paid less for a prize than it's (eventually) worth. I also don't see why you're upset that the winner of the game won the advertised prize.
It bothered me that the exact same game was valued less in a special event than it was in an ordinary event.
