The "Active games" tab in the Game and Player Information portion of the screen contains a list of games which are currently in progress on the TilingKing server. To observe a game in progress, click anywhere on the information for the game of interest. The game board will appear as it is seen by the game's players and you will be able to see each player move as it happens. You will not see the pieces being dragged onto the game board, however, nor are you able to see the player's clocks at this time.
