Although Gene didn't exactly score the main game in dollars (on the shows I've seen on YouTube, Gene just says "you get 25" or something like that.), to win the game and go to the audience match a team has to score 100. Then during the Audience Match Gene very clearly says "you get fifty dollars for the answer you match most often"--and the 50 is always added to the team's original 100. So although there wasn't a big dollar sign on the scoreboards, it seems like Match Game worked by "first team to $100." Not sure if you ended up scoring over 100 (thanks to a tie or matching both on the last question) if they'd pay the extra.
It seems to me he'd call them points, but, yes, the winners received $100. I wonder if the thinking was that if he said $25 instead of 25 points, they'd have to pay the loser, too. On _ Jeopardy!_, Alex is very explicit that "only the winner keeps the cash," partly because that was a change from Art's version. Jack Barry didn't really bring it up, though. They just blanked the loser's score and mentioned only parting gifts.
I still kind of wonder if on TJW, if player 1 goes over $500 then player 2 spins three jokers and wins if player 2 wins $500, the amount player 1 scored, or that amount plus $1 or $50.
