Premium Squares

Premium squares are squares on the board such as 4W, 3W, 2W, 4L, 3L, 2L, -5 and -10.

2W doubles the points scored for a word played over it
3W triples the points scored for a word played over it
4W quadruples the points scored for a word played over it
2L doubles the points scored for a letter played over it
3L triples the points scored for a letter played over it
4L quadruples the points scored for a letter played over it
-5 subtracts 5 points from each word played over it
-10 subtracts 10 points from each word played over it

Note that if a word covers more than one of the multiple word squares (4W, 3W, 2W) in a single play, the score after multiplying the word is multiplied again for each square covered. For example, it is not the case that covering two 3W's is to multiply the word by six, the effect is to multiply the word by nine.
