If you go "My Home-> Online Chess" you can see the status of all your games and that will show the games that are waiting for your move. If you make a move on one game and submit the move, it automatically brings the next game where its your turn to move ( I am not sure if it brings the one in which you have least time available...). If not, then probably its a suggestion for improvement.
Erik, kindly note!
I do not see that it is my move. I have to check all games !!!
