Welcome to the game! Here are the rules:
    
      - Every player inserts an integer number between 0 and 100.
 
      - When everyone has played (when we will decide to stop the game), the system will compute the average of all the numbers.
 
      - All the players that inserted a number below or equal to 80% of the average will win.
 
      - The prize will be proportional to your inserted number and the total number of players that have played.
 
      - Enjoy the game and have fun!
