It's been a while since I played Scrabble, but I do remember the frustration of trying to keep tiles in place!  I played this with my niece the other day and I was surprised at how small the tiles were.  I'm not sure how they compare to regular Scrabble pieces, but they seem TINY to me!  Other than that, the tile locks do exactly what they say and even my parents thought it was a pretty cool feature.  Great to have a new spin on an old classic!
