Is there a popular Scrabble variation that:
lets you play double/triple word scores twice, once vertically and once horizontally?
does NOT let you play double/triple letter scores twice?
This is how I've always played, so it surprised me to learn that official Scrabble rules do NOT permit using double/triple word scores twice.
Perhaps this was true in an older version of Scrabble (I started playing in the 70s).
