The Game
• Think about what types of objects
we will need in our system and some
of the properties and capabilities of
those objects.
• The next slides show the results of
our brain-storming

• Ability to flip from one to another
Theme
• All cards that we are matching should
have a theme.

Some Notes
• Some of these objects are directly
from the problem domain
• Some of these objects creep into
implementation details
• Focus first on the overall system and
then worry about the specific
implementation details.
Next time
• Think about how the user will
interact with the system
• What should the user have to “do” to
play the game
• How should the game look
