Example: An Educational Game (CRC Cards)

• Whose responsibility is it to play a round?
  • The Game class
  • The Player class
• It probably doesn't matter, so we will choose the Game class.
• What happens in a round?
  • Make a time (uses Time class).
  • Draw a clock (uses Clock class).
  • Ask for input (uses Player class).
  • Check input (uses Clock class)
  • Ask again or increment score (uses Player class).

• There is no need for Round and Level classes, so do not implement them.
