you appear to have missed the point - I was replying to the question about rankings - not asking about them - I pretty much said exactly the same thing in different words!! But thanks anyway!!

@betterlate1 I assumed that was what the question was about! Maybe there's some other kind of ranking system unknown to me. I'm a refugee from the dreadful new "scrabble go" platform - quite why any company would abandon a perfectly good app for something so crap is beyond me!!

the ratings rely on the "ELO" system which means you get less points playing plays of similar or lower ratings than you and more for beating players with higher ratings - you can check out the details on wikipedia https://en.wikipedia.org/wiki/Elo_rating_system
