Why are scrabble letters different points?

Answer 1

The creator of Scrabble, an architect named Alfred Mosher Butts, is said to have tallied the frequency of each letter on the front page of The New York Times to determine how many tiles there would be per letter and how much each letter would be worth. Letters that occurred most often, like E or T, would be worth only 1 point, and harder to use letters, like Z and Q, would be worth 10.

Answer 2

Because it is harder to make words with z`s and q`s in them than it is to make words with a`s and e`s. The presumption is that when the game was being developed there was an attempt to match the difficulty of using various letters in words with the points associated with those letters.

Answer 3

The score value of each letter is indicated by a number at the bottom of the tile. The score value of a blank is zero. The score for each turn is the sum of the letter values in each word(s) formed or modified on that turn, plus the additional points obtained from placing letters on Premium Squares.

Answer 4

NONSENSE!

Answer 5

infrequency of use in a word, got a higher score
