For all three difficulty levels the cards are dealt completely at random to both you and to the computer. The difference between the easy, standard and pro levels is the strategy used to choose the computer's discards and pegging plays. If you are finding that your computer opponent is beating you, you will likely benefit from understanding how the computer chooses its next move.

Cribbage, or crib, is a card game traditionally for two players, but commonly played with three, four or more, that involves playing and grouping cards in combinations which gain points. Cribbage has several distinctive features: the cribbage board used for score-keeping, the eponymous crib, box.

Discarding:	Chooses a random pair of cards.
Pegging:	Chooses a random valid card.

Discarding:	Chooses the pair of cards that will result in the best hand score ignoring the possible flip card. If the discards are a pair or sum to 15, it adjusts the analyzed hand value by 2 (plus or minus depending on the crib owner.) Notice that this strategy does not account for flushes or possible runs that could result from the flip card.
Pegging:	Chooses the next card that will result in the highest score for itself. If all plays are of equal value then it chooses at random.

Discarding:	Evaluates the score for each pair of discards for all possible flip cards still left in the deck. Then takes the play that averages the highest outcome. For the cards in the crib, evaluates their value as well with each possible flip card and adds or subtracts depending on who will count the crib. Note that the potential from the two additional crib cards are not included in the crib analysis.
Pegging:	Chooses the next card that will result in the highest score for itself. It also prefers not to leave the pegging count at 5 or 21. If all plays are of equal value then it chooses at random.
