There's also Luckyflop.eu and if you join you can take part in several GTDs and Freerolls happening daily and more on weekends, there's a 10 mBTC GTD today, so if you want to take part in that go ahead and make an account. The link you for the thread and the site can be found in my signature. They have a Client for Mac and Windows and if you don't prefer to download and install stuff then you can play in your browser itself.
What many players who play there ?
I'm always looking for a place to play poker , but only a few players at the table
Like poker playtodos only 10 players online
I am also interested to try SWC poker, can I play using a smartphone ?
AFAIK, they only have a PC Client as of now and therefore you won't be able to play using your smartphone as there is not even a browser version.
