The object of the game is to match the cards, turning over two cards at a time, if they match they will disappear. Keep turning over the cards until they are all gone.
After the cards are all gone, you will be asked to enter your name, your score will be added, and stored in a database.
Under "info" you can see the names, and scores.
Under "Options" you change the type of cards that come up, turn sound on or off, and clear the database.
