Don't "slam" this game -- I've played this game with children ages 5 to 9, and also watched kids playing it amongst themselves without any adults, and have always seen the kids enjoying themselves. Kids love the tactile element in games, and in this quick card game they get that a huge heaping of that -- the first to slap the double-decker, or the slamwich, or the thief -- it's just great fun for them. Probably not going to keep them busy for an hour, but for 15 to 20 minutes it's great fun. Also, it's very easy to teach them, and for kids to teach to other kids.

If you are looking for a game for the preK-Grade 1 set, than this may fit the bill. Beyond that, it lacks any real thinking skills and quickly bores older kids (and parents). And the slapping! It was the cause of too many arguments about who actually slapped the card first! This game sits at the back of our game cabinet unused since the first day we tried it.
