I played The Trivia Countdown Game: People Places and Things (Kwizniac Kidz) with my family. In this game, someone reads you five clues in decreasing order of difficulty. Each clue is easier than the one before it. You get more points if you answer the question with a difficult clue. At the end, the person with the highest score wins.
I didn't really like this game. Some clues weren't kid-friendly, so I think it is best for kids 12 and older. My parents understood the clues and liked it more than I did. I didn't get them and neither did my twin sister. But try it for yourself online: go to kwizniac.com, and click on "About the Game: Try It Out."
