It was basically "The Newlywed Game", but instead of asking husbands and wives about each other, they would ask parents and kids. One problem was that some families had 4 kids on and some only had two. The episode my family was on we had 4 teenage kids, another family had 4 adult kids, and the third family had 2 pre-teen kids. Also, the prize was a trip for the parents without the kids. It didn't seem to have a very long run, and I'm not even sure if it aired outside of BC. It was taped in the main studio at Lake City (the same one they do the Children's Miracle Network Telethon).
Spoiler: My family won when we were on, and my parents got a trip to Waikiki Hawa'ii.
