The flip counter can be removed from the game. You must still show the score, however.

… just remove to flip label in storyboard …

The complete code is available on github.

If there are more cards than will fit on the screen, simply allow the user to scroll down to see the rest of the cards. Pick a fixed (and reasonable) size for your cards and keep them that size for the whole game.

… which the code already does by default …

It is very important that you continue to have a “last flip status” UI and that it show not only matches and mismatches, but also which cards are currently selected (because there can be so many cards now that you have to scroll to get to all the cards in a match). A UILabel may no longer be sufficient for this UI.

To rewrite the current status label the updateUI method has to be overwritten by the set-game view controller. Do display the card symbols in the status label, we will add a subview for each card. At the start we make sure there is no subview from a previous status display. If there are any we loop over each of them and remove it.

Do something sensible when no more cards are in the deck and the user requests more.

There a various “sensible” solutions, lets just disable the button and gray it out, when there are no cards left in the deck:

- (IBAction)addCardsButtonPressed:(UIButton *)sender {
    ...
    if (self.game.deckIsEmpty) {
        sender.enabled = NO;
        sender.alpha = 0.5;
    }
}

Automatically scroll to show any new cards when you add some in the Set game.

After a the data has been reloaded scroll to the last item:

- (IBAction)addCardsButtonPressed:(UIButton *)sender {
    ...    
    [self.cardCollectionView scrollToItemAtIndexPath:[NSIndexPath indexPathForItem:(self.game.numberOfCards - 1) inSection:0]
                                    atScrollPosition:UICollectionViewScrollPositionBottom
                                            animated:YES];
}

In the Set game (only), the user must always have the option somewhere in the UI of requesting 3 more cards to be dealt at any time if he or she is unable to locate a Set.

In storyboard drag out a new button set its tag to 3, provide a suitable name and link it to an action in the game view controller (or the set-game view controller – either works).

Set cards must have the “standard” Set look and feel (i.e. 1, 2 or 3 squiggles, diamonds or ovals that are solid, striped or unfilled, and are either green, red or purple). You must draw these using Core Graphics and/or UIBezierPath. You may not use images or attributed strings. Use the PlayingCardView from the in-class demo to draw your Playing Card game cards.

Adjust the drawRect: method of the set-card view to call a new method to draw the symbal (which is actually not really necessary but makes the code a little bit more sructurized):

When a Set match is successfully chosen, the cards should be removed from the game (not just blanked out or grayed out, but actually removed from the user-interface and the remaining cards rearranged to use up the space that was freed up in the user- interface).

The card-matching-game model needs a new property to show how many cards are currently available, and a new property to remove a specific card:
