Simplify the following text for a Grade 6 native English-speaking person.
Original: The board is marked with `` premium '' squares , which multiply the number of points awarded : dark red `` triple-word '' squares , pink `` double-word '' squares , dark blue `` triple-letter '' squares , and light blue `` double-letter '' squares ( In 2008 , Hasbro changed the colors of the premiums squares to orange for TW , red for DW , blue for DL , and green for TL ) .
Simplified: There are several squares on the board where a player can get extra points . Some squares allow the player to count that letter twice ( light blue ) or three times ( dark blue ) , other squares allow him to count the whole word twice ( light red ) or three times ( dark red ) .
