Temporary random value scrabble tiles

Ordinary Scrabble has set values and numbers of tiles per language. This is less interesting than a potential service you could sign up to.

Once a month, the usual number of light-sensitive sets of scrabble tiles arrive in the post. However, the frequency distribution of the letters is random, as are the values of each letter, although each type of letter has the same value. Hence you might get a lot of Z's with low values, which makes it easier to play the Polish version, for example, but not, say, the English version. Also, on exposure to light, the tiles gradually fade until the letters and values have disappeared. You then return the set in the pre-paid envelope to be reprinted.

This changes the game. One can acquire specific skills on a specific set over the month which will then be less useful in the next month, and an element of luck is introduced, somewhat like gambling but less effective at emptying one's bank account. One might, though, acquire more general skills. The actual experience Scrabble players gain becomes less useful.
