I'm check game with machine and my mouves didn't accepted.
Well I don't know. Must be an opera bug. You'll have to use another browser.
One more word about my problem.
At Firefox I'm can't join in any game at first time, while I can see this message:
Bummer!
Your browser supports websockets, but cannot get a connection.
Maybe you are behind a proxy that does not support websockets.
Ask your system administrator to fix it!
After refresh (F5) page this message go out and I can start a game.
May be that will be some helpfull.
P.S. In opera this message shown my any time
