positive.code: 
  The aim of the game is to consolidate recently learned vocabulary. 
  For this purpose the class composes a vocabulary list of words or expressions,
  hereafter referred to as secret words words.
  
  *  The class composes the list of secret words together with the teacher.  One
     pupil types the suggested words into the configuration file, the others
     follow at the screen and correct spelling mistakes. 
  
  *  The list of secrets can be recent vocabulary or calculation exercises. A
     secret can be one word only, a whole expression or a sentence.
  
  *  As a hint it is possible to tag a part of the secret sentence. This part
     will be disclosed immediately when the game starts.   
  
  *  When the game starts the computer will choose one secret of the list randomly.
     Even the teacher does not know.
  
  
  === Game rules
  
negative.code: 1. The whole class is asked to write down all guessed letters on a sheet of 
     paper.
  
  2. A player can guess again when when the last guess was right, meaning the
     secret contained the guessed letter.
  
  3. If not, the next player may try it. In bigger groups the next player should
     be chosen randomly. This incites the whole group as nobody knows who will 
     be the next.
  
  4. A player is not allowed to ask others to remind him if a letter was already
     tried or not. He has to solely rely on his own notes.
  
  5. The winner of the game it the person who discloses the last letter of the
     secret word.
