Scrabble rules simplified

A blank Scrabble board looks like this:

Premium Squares:

Dark blue = triple letter score
Light blue = double letter score
Pink = double word score
Red = triple word score

1. You must play in a straight line. All letters must touch at least one other letter. On the first move you must play 2-7 letters with one letter on the central square. On other moves you must play 1-7 letters.

2. After every move all words (reading from left to right and from top to bottom) must be valid. You can check validity at Scrabble Word Finder

3. You score for all words created in a move.

4. Premium letter scores apply before premium word scores. Premium letter and premium word scores apply only once for each square, when first a letter falls upon the square. If a word falls on more than one premium word scores, you multiply the premium scores together.

5. A bonus of 50 applies to using 7 letters in a move.
