The Game• Think about what types of objects

we will need in our system and some of the properties and capabilities of those objects.

• Ability to flip from one to another

Theme• All cards that we are matching

should have a theme.

Timer• Controls the length of time the

user can play the game.

Cursor• Change cursor to a hand or some

other image rather than an arrow.

been selected.• Perhaps holds onto the second

card that has been selected as well.

upon.

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
