The ParallelGamePlayer class implements the Player interface that defines the play method:

@Override 
 public void play() { 
     Table table = new Table(NR_COLUMNS, manager); 
     Secret secret = new RandomSecret(manager); 
     Guess secretGuess = secret.createSecret(NR_COLUMNS); 
     Game game = new Game(table, secretGuess); 
     final IntervalGuesser[] guessers = createGuessers(table); 
     startAsynchronousGuessers(guessers); 
     final Guesser finalCheckGuesser = new UniqueGuesser(table); 
     try { 
         while (!game.isFinished()) { 
             final Guess guess = guessQueue.take(); 
             if (finalCheckGuesser.guessMatch(guess)) { 
                 game.addNewGuess(guess); 
             } 
         } 
     } catch (InterruptedException ie) { 
  
     } finally { 
         stopAsynchronousGuessers(guessers); 
     } 
 }

This method creates a Table, a RandomSecret that creates the guess used as a secret in a random way, a Game object, IntervalGuesser...
