There
are 94 tiles in total ranging in point value from
zero to nine.
Letters are presented
below in order by their frequency in English
words (according to http://www.askoxford.com/asktheexperts/faq/aboutwords/frequency).
As you can see, this
forms the primary basis for the distribution of
tiles and assigned point values (with a little
tinkering by the inventor based on experience
with the game).
This tile distribution
is reflected in version 2.0 or later. Earlier
versions used a slightly different set.
