Winning Lines is an American game show that aired from January 8, 2000, to February 18, 2000, the day after its official cancellation.

[1] Adapted from the British format of the same name created by David Briggs, Mike Whitehill and Steven Knight, it was considered as CBS's answer to the success of ABC's Who Wants to Be a Millionaire.

Winning Lines was hosted by Dick Clark,[2] directed by James Yukich and produced by Stone Stanley Entertainment in conjunction with the British production company, Celador.

Clark asked a series of mathematical questions, each of which could be answered with the number belonging to one of the contestants still in play at the time.

A button near the contestant's seat glowed red once either two strikes had been earned or there were 15 seconds left in the round, whichever came first.

If the contestant ran out of time or accumulated three strikes without bailing out, he/she lost all winnings from the Wonderwall and left with only the $2,500 won in the main game.
