Pig Game GUI

Pig is a folk jeopardy dice game with simple rules: Two players race to reach 100 points. Each turn, a player repeatedly rolls a die until either a 1 ("pig") is rolled or the player holds and scores the sum of the rolls (i.e. the turn total). At any time during a player's turn, the player is faced with two decisions:

Problem:  Implement a GUI for the game of Pig where the user plays a succession of games against a computer player.  A brief summary of software requirements follows.


Your goal is to create a simple-yet-fun GUI implementation of the game of Pig.  The user is the starting player of the first game.  The starting player alternates with successive games.  The computer plays a "Keep Pace and End Race" policy as follows:  Let the hold value be 21 + round((user score - computer score) / 8).  If either player has 71 points or more, or if the turn total is less than the hold value, then roll.  Otherwise, hold.

Extra Exercises:

1. Use an alternative computer play policy.  Let i be the player's score, j be the opponent's score, and k be the current turn total.  Some alternative play policies:

2. Compute win statistics (e.g. games won, games lost, percentage won) and display these at game end.

3. Extend design to three or more user/computer players.

4. (Advanced Project) Extend design to three or more user/computer players over a network, using a client-server model.
