Aganju: It seems to me that BrainKing should never display a game as active if time has expired. I would almost certainly guess that the ending time of the game is what's stored in the database, so, in order to show the game page to a user, the time remaining must be calculated every time the game page is shown to the user. BrainKing should detect when the time remaining is negative and should end the game right then and there rather than show games with negative time remaining and allow users to continue to play in them.
