My kids love this game.  They beg me to play it any chance they get.  While the adults aren't so fond of it, my daughter is old enough that she can generally play with her brother without too much incident (unless she cheats again...  The game play is simple enough that we were able to introduce it to my son when he was too, but he needed a lot of assistance.  I think the idea of being included was more appealing to him than the game itself.  For an average sized family, this is a wonderful game that I remember playing when I was little.  This classic game still entertains children today.  The only down side?  The game pieces are fairly easy to break and the cards have no way of being contained, so you'll need to provide your own elastic to bind the cards.  Thankfully, when our first game's pieces broke we simply replaced them with different coins we had around the house and the kids loved that.  Eventually we did end up replacing the game.
