This will be a down and dirty review.  First of all the board is very small.  It is for traveling and you can not really have a full size board when you are traveling around.  It is about 10 or so inches by 10 inches big.  This is small and the words on the board are small.  Second, the tiles to not lock per say, they fit very well and unless you hit a pothole the pieces should stay in.  Finally, the pieces are small, as in probably no more then 1/3 and inch by 1/3 and inch.
