The answer to your question would be YES, those games all do have free ratings!!!
Chess does, that I know for sure, as I play it often. They still have the free rankings/points system.
And plenty of people joined when they gave out free rankings, it's when they started charging that people left, DOI! Now yeah, I know, they need to make a profit...they can make it off of those few who want to play the newer versions. But they should never have degraded the classic version at the same time!!! They should've just left it alone so that people who always came here and played for free could continue to do so, while those enticed by the new versions of the games could pay their $20 fee if their mommies and daddies let them.
