“In regular scrabble, you record the score. It’s assur miderabanon. In Scrabble, the pieces interlock, it’s really writing and it’s assur mideoraisa.”
False on all three. My wife and I play Scrabble regularly. We don’t record the score; we keep track using bookmarks in books, so nothing is getting recorded at all. And as anyone who has ever played Scrabble knows, the pieces do NOT interlock. In some of the more deluxe editions of Scrabble the boards do have squares with raised edges to hold the pieces which as noted above does cause halachic concerns; we just use the old flat cardboard playing board that causes no concern.
