After researching the top games on Amazon for Christmas gift ideas, I landed on this game.  The reviews that I read sounded fun, so we decided that this would make a great gift for our oldest sons, ages 9 and 10.  I knew this game had to be a top seller for a reason, but I was seriously blown away by how fun this game is!  This game utilizes both strategy and luck.  Our kids are able to understand the rules and provide very good competition to the adults who join in.  This has become a favorite and we've been playing it several nights per week for over a month.  Typically, it takes an hour and a half to complete the game, and each time we play new critical thinking skills are used. I would recommend this game for ages 8 and up.
