I know for gambit, I played there before. Interesting site with good games, I played a lot in one period. I didn't know you can earn bitcoins there, when I was there I think there was a chance to win some dollars, but I never made anything so I don't really know how it goes.

Nice list, thanks for posting this, I will try this games from first to last one. I also wish to find some interesting game to play, it's good sometimes, and winter is coming I will spend more time inside.
