I bought this game because my 4 year old grandsons love the Pete the /Cat books.  However, this is about the worse game for pre-school children I've ever seen.  They could have provided actual cups to hold the buttons on, as little kids had trouble stacking their buttons on the flat board cup, having kids trade "cups" of buttons is even more ridiculous!  This games should have followed the simple format used by other color coded games.  When we played, I had to change the games format/goals to doable for 4 year olds.
