4 in a Row line up game

This is a take off on the pastice game where line up the red and black discs to try to connect 4 in a row to win.  The nice thing is that this one is made from wooden pieces and my grand kids love it.  We like the wooden puzzles etc, so this is a big hit.    My grandson that is only 3 likes to put the discs in and will do it for a long time.  It's great when you can find something that will keep a 3 year old busy for longer than a minute.  I keep this in my car and take it into restaurants to keep them busy while we wait for our food.  It's quiet and they even play together sometime.
