I absolutely love this game!  It's always different, and can be played by many different age levels.  Even my mother, who has Alzheimer's, can play a simplified version.  We do crosswords, and she builds separate words - but still "dumps" and "peels"  with the rest of us!  My problem is this.  I love this game so much, I gave my original game to my parents, since my mother also enjoyed it a lot.  I ordered two more.  The original set has heavy tiles - weighted and smooth.  Very nice to manipulate.  The new version has cheap lightweight plastic tiles.  Ugh.  The learning value is the same, but the cheaper quality of the materials bothers me.  The lighter weight tiles seem to fall more easily, and are not as durable.  One fell on the floor and inadvertently got stepped on...and it cracked.  That would not happen with the original tiles.  So - look around for those older sets!
