I've been playing the Curling game for a few months. It's fun and it's well designed, but I think there's some kind of discrepancy in the rating system ... here are some examples:
- a game where I won 3-2, my opponent then left the game, neither of our rating changed;
- I have won games before and yet my rating got dropped! (no, I didn't quit the game in the middle ... the game was finished and I won by 2 or 3 points).

Not sure if this has happened to others but I think it's worth checking into the programming to see if there's something wrong with the rating algorithm.

Thanks and Good Curling!
