III. Overview & Requirements:
Develop and implement an interactive two-player Yahtzee game. Yahtzee is a dice game that was
invented by Milton Bradley and Edwin S. Lowe in 1956. The challenge of the game is to outduel
the other player by scoring the most points. Points are obtained by rolling five 6-sided die across
thirteen rounds. During each round, each player may roll the dice up to three times to make one
of the possible scoring combinations. Once a combination has been achieved by the player, it
may not be used again in future rounds, except for the Yahtzee combination may be used as
many times as the player makes the combination. Each scoring combination has different point
totals. Some of these totals are achieved through the accumulation of points across rolls and
some are obtained as fixed sequences of values.
The Rules of Yahtzee:
The scorecard used for Yahtzee is composed of two sections. A upper section and a lower
section. A total of thirteen boxes or thirteen scoring combinations are divided amongst the
sections. The upper section consists of boxes that are scored by summing the value of the dice
matching the faces of the box. If a player rolls four 3’s, then the score placed in the 3’s box is the
sum of the dice which is 12. Once a player has chosen to score a box, it may not be changed and
the combination is no longer in play for future rounds. If the sum of the scores in the upper
section is greater than or equal to 63, then 35 more points are added to the players overall score
as a bonus. The lower section contains a number of poker like combinations. See the table
provided below:
Name Combination Score
Three-ofa-kind Three dice with the same face Sum of all face values on the
5 dice
Four-ofa-kind Four dice with the same face Sum of all face values on the
5 dice
Full house One pair and a three-of-a-kind 25
Small straight A sequence of four dice 30
Large
straight A sequence of five dice 40
Yahtzee
(think fiveof-a-kind)
Five dice with the same face 50
Chance May be used for any sequence of dice;
this is the catch all combination
Sum of all face values on the
5 dice
What is required for this assignment?
You may design the Yahtzee game with functions that you see fit. I recommend that you start
with a structure chart and determine sub-problems and functions accordingly. You must also take
advantage of applying pointers, output parameters, and/or arrays! Your Yahtzee game must also
implement the following algorithm:
(1) (5 pts) Print a game menu for Yahtzee with the following options:
1. Print game rules
2. Start a game of Yahtzee
3. Exit
(2) (5 pts) Get a menu option from the user; clear the screen
(3) (10 pts) If option 1 is entered, then print the game rules stated above and repeat step (1)
otherwise if option 2 is entered, then continue on to step (4); player 1 starts the game
otherwise if option 3 is entered, then print a goodbye message and quit the program
otherwise repeat step (1)
(4) (5 pts) Ask the player to hit any key to continue on to roll the five dice
(5) (5 pts) Roll the five dice and display the face values of each die; enumerate each die with
a number 1 – 5; add 1 to the total number of rolls for this round
(6) (10 pts) If the total number of rolls for this round is less than three,
then ask the player (Y/N) if he/she wants to use the roll for one of the game combinations
otherwise a combination must be selected.
1. Sum of 1’s 7. Three-of-a-kind
2. Sum of 2’s 8. Four-of-a-kind
3. Sum of 3’s 9. Full house
4. Sum of 4’s 10. Small straight
5. Sum of 5’s 11. Large straight
6. Sum of 6’s 12. Yahtzee
13. Chance
(7) (15 pts) If the number of rolls is three or “yes” is entered, then save the combination and it
may not be selected again in the future
(Note: The selection of the combination must be verified. If the user selects full
house, but does not have one, then your
must assign 0 points for the combination);
continue on to step (8); clear the screen
otherwise if “no” is entered, ask the user which dice to re-roll (1 – 5); re-roll the selected die
or dice; clear the screen;
repeat step (6)
otherwise repeat step (6)
(8) (5 pts) Alternate players
(9) (10 pts) If each player has rolled for the round, then increment the round number
if the round number is equal to 14, then continue on to step (10)
otherwise repeat step (4)
otherwise repeat step (4)
(10) (5 pts) If the total score in the upper section is greater than or equal to 63 for a player, then
add 35 points to the total score
(11) (5 pts) Print the scores for both players and print the winner
(12) (5 pts) Repeat step (1)
IV. Expected Results:
I recommend that you check out this website http://www.yahtzeeonline.org/ to grasp the game
play for Yahtzee. Of course, the game you build is text based.
V. Submitting Assignments:
1. Using Canvas https://canvas.wsu.edu/, please submit your solution to the correct
“Programming Assignments” (PA) folder. Your solution should be zipped into a .zip file with
the name _PA5.zip and uploaded. To upload your solution, please
navigate to your correct Canvas lab course space. Select the “Assignments” link in the main
left menu bar. Navigate to the correct PA submission folder. Click the “Start Assignment”
button. Click the “Upload File” button. Choose the appropriate .zip file with your solution.
Finally, click the “Submit Assignment” button.
2. Your project must contain one header file (a .h file), two C source files (which must be .c
files), and project workspace.
3. Your project must build properly. The most points an assignment can receive if it does not
build properly is 65 out of 100.
VI. Grading Guidelines:
This assignment is worth 100 points. Your assignment will be evaluated based on a successful
compilation and adherence to the program requirements. We will grade according to the
following criteria:
85 pts for adherence to the algorithm stated above (see the individual points above)
10 pts for appropriate top-down design of functions and usage of pointers and/or arrays
5 pts for adherence to proper programming style established for the class and
comments
