I got a question for you: Passage: Since the genre began, many shows have offered prizes of large sums of money to contestants; Teddy Nadler set the original monetary winnings record of $264,000 during his appearance on The $64,000 Challenge in 1957. Nadler was not surpassed until 1980, when Thom McKee won $312,700 on Tic-Tac-Dough. In 1999, John Carpenter won $1,000,000 on Who Wants to Be a Millionaire, becoming the first person to win a seven-figure prize on an American game show. Since then, many players have gone on to win that amount and even surpassed it. As of 2015, Brad Rutter is the highest-earning American game show contestant of all time, having accumulated a total of $4,555,102. He succeeded Ken Jennings as the highest-earning contestant by virtue of his victory on May 16, 2014, in the Jeopardy! Battle of the Decades tournament.\n\nQuestion: Based on this passage, who won the most money on a game show?
