I purchased this game for our 5 1/2 year old daughter thinking I would hate the game but the rest of the family would enjoy.  Well I was pleasantly surprised -it is my favorite game to play, and not just because I win often.  Our daughter enjoys it as well.  We let her keep score which is one of the reasons she likes the game.  She has beaten the adults before.  We plan fairly -we don't need to dumb it down for her, she can hold her own and thinks about which tiles will give her the most points.
