Score a game of Yahtzee

Question

For each of the 13 rows of a Yahtzee scoresheet you are given (from stdin) a space separated list of 5 numbers (dice). Your task is to calculate the score for each line and output the Grand Total of the game.

Example

Input and how to interpret it:

Input       Box              Score
6 1 4 1 3   Aces              2
3 2 2 1 2   Twos              6
6 3 2 3 3   Threes            9
4 2 3 6 5   Fours             4  
6 3 5 5 1   Fives            10
1 5 6 5 6   Sixes            12
            Bonus             -
4 2 4 4 1   3 of a kind      15
2 2 3 2 4   4 of a kind       -
3 2 2 2 3   Full house       25  
1 3 1 6 1   Small straight    -
2 5 4 6 3   Large straight   40
2 2 2 2 2   Yahtzee          50
5 5 4 5 2   Chance           21
            Grand Total     194

We will disregard the Yahtzee Bonus and Joker rules, and only sum up the scores from the Upper and Lower Section and the Bonus in the Upper Section. If in doubt, refer to these rules.

May the shortest code win!

Answer 1

R - 264

S=sum;
P=prod;
T=function(i)table(x[i,]);
Z=function(i,...)any(sapply(list(...),function(y)all(y%in%x[i,])))
S((x[1:6,]==(R=row(x[1:6,])))*R)+ # Upper section
S(x[7,])*any(T(7)>2)+             # 3 of a kind
S(x[8,])*any(T(8)>3)+             # 4 of a kind
25*(P(T(9))%in%5:6)+              # Full house
30*Z(10,1:4,2:5,3:6)+             # Small straight
40*Z(11,1:5,2:6)+                 # Large straight
50*(P(T(12))==5)+                 # Yahtzee
S(x[13,])                         # Chance

With the input

x <- as.matrix(read.table("http://pastebin.com/raw.php?i=ZRMC9B4x"))

Output

[1] 194

APL (124)

Answer 3

Python 364

S=sum;R=range;D=[map(int,raw_input().split())for i in R(13)];s=S(x for i in R(6)for x in D[i]if x==i+1)
for i in R(2):d=D[6+i];s+=[0,S(d)][max(map(d.count,d))>2+i];d=sorted(set(D[9+i]));s+=[0,30+i*10]['1, 1, 1'+', 1'*i in`[d[x+1]-d[x]for x in R(len(d)-1)]`]
e=D[8];a=map(e.count,e);d=D[11];print s+S(D[12])+[0,50][d.count(d[0])==5]+[0,25][2in a and 3in a or 5in a]

As requested, input is on stdin:

$ yScore.py < dice.txt
194

If the data could be preloaded into a list, as some other solutions have done, I could remove 62 characters to get to 302.

Answer 4

Mathematica 359

y = IntegerDigits@ImportString[x, "Table"][[1]];
l = Length; g = Gather; r = Range; b = SortBy; h = l@b[g[y[[#]]], l][[-1]] &;
Tr@Flatten@{# Count[y[[#]], #] & /@ r@6, If[h@7 == 3, 15, 0], 
If[h@8 == 4, 20, 0], If[(l /@ b[g[y[[9]]], l]) == {2, 3}, 25, 0], 
If[MatchQ[Sort@y[[10]], {___, n_, m_, o_, q_, ___} /; m == n + 1 && o == m + 1 && q == o + 1], 30, 0], 
If[Sort[y[[11]]] == r[y[[11, 1]], y[[11, 1]] + 4], 40, 0], 
If[l@g[y[[12]]] == 1, 50, 0], y[[13]]}

There must be a more efficient way to check for the short straight.

                            # (needed for processing the first 
                            # half of the board)

[       # create an array of code blocks, for scoring:

        # yahtzee:

        #chance:

{~~}%           # evaluate each input/code pair

{+}*            # sum up the partial scores.
