The solution can be tested here.

Python, 112 110 chars

from random import*
r=randrange(6)
C='o '
s='-----\n|'+C[r<1]+' '+C[r<3]+'|\n|'+C[r<5]
print s+C[r&1]+s[::-1]

Answer 5

Python, 109 unicode characters

#coding:u8
print u"鱸헓ȅ᪮ԅ᪅餠☏汁끝鐸즪聗K糉툜㣹뫡燳闣≆뤀⩚".encode("u16")[2:].decode("zlib").split("\n\n")[id(list())%7-1]

Note: This does not used random function, so it will be not so random like others does.

Answer 6

Perl, 74 chars

Run with perl -M5.010.

$-=rand 6;$_="-----
|0 2|
|4";s/\d/$->$&?o:$"/ge;say$_,$-&1?$":o,~~reverse

(Note that the newlines in the listing are part of the string, and not just inserted for legibility.)

If you find yourself wondering what the heck the $->$ operation does, the following reading notes may be helpful:

• The variable $- automatically truncates its assigned value to an integer.

• The variable $" is preset to a single space.

• o is a bareword (representing "o").

Python, 161 chars

from random import*
n=randint(1,7)    
o,x='o '
a='-'*5
b=(x,o)[n>3]
d=(x,o)[n>5]
c=(x,o)[n>1]    
print a+'\n|'+c+x+b+'|\n|'+d+(x,o)[n%2]+d+'|\n|'+b+x+c+'|\n'+a

Answer 8

JavaScript, 215 213 212 145 135

r=Math.random()*6|0;alert('-----\n|'+[r>2?'o o':r?'o  ':'   ',r%2?r>3?'o o':'   ':' o ',r>2?'o o':r?'  o':'   '].join('|\n|')+'|\n-----');

Beat mellamokb, but I changed my original solution completely. If you want this to look good, use Google Chrome or something, change alert to console.log, and voilà.

Edit: borrowed mellamokb's |0 trick to save some characters.

Answer 9

Common Lisp 170

(let*((r(random 6))(a "-----
|")(c "o")(d " ")(e "|
|")(f(concatenate 'string a(if(< r 1)d c)d(if(< r 3)d c)e(if(> r 4)c ))))(concatenate 'string f(if(evenp r)c d)(reverse f)))

Note that the newlines are significant. Unlike these silly "modern" languages, Common Lisp favors readability over succinctness, so we have the cumbersome "concatenate 'string..." construct and no succinct way to reference a character in a string.

Answer 10

JavaScript (169 168 141 137)

r=Math.random()*6|0;s='-----\n|'+(r>0?'o ':'  ')+(r>2?'o':' ')+'|\n|'+(r-5?' ':'o');alert(s+(r%2?' ':'o')+s.split('').reverse().join(''))

Doesn't look quite right in alert because it's not fixed-width font, but rest assured it is correct, or test by emitting a <pre> tag and doing writeln :-)

Proof: http://jsfiddle.net/d4YTn/3/ (only works in JS 1.7-compliant browsers, such as FF2+)

Credits: Hacked Math trick from @minitech and die print logic from @Keith.

Edit: Remove Math trick from @minitech because it actually made it longer :-)

Edit 2: Save 17 chars. Borrow trick from @Keith for taking advantage of dice symmetry. Use trick for simplifying converting random number to int.

Edit 3: Remove 1+ to shift random number from 1-6 to 0-5 and save 2 chars. As a result, I can also change r%2-1 to r%2 and save another 2 chars.

Edit 4: jsfiddle is working again. Updated :-)

It uses roughly the same idea as the Python one.

Readable version:

import System.Random

main = do
    x <- randomRIO (1 :: Int, 6)
    putStrLn (render x)

render x = str ++ check odd ++ reverse str
  where
    str = concat
        [ "-----\n|"
        , check (> 1)

Answer 23

C, 168 164 163 chars

Sorry if I'm a bit late to the party, but since no answer has been accepted yet, and the only other C solution was somewhat longer, here goes...

#include<stdio.h>
main(){srand(time(0));char*o="O ",r=rand()%6,i=o[r<1],j=o[r<3],k=o[r<5];printf("-----\n|%c %c|\n|%c%c%c|\n|%c %c|\n-----\n",i,j,k,o[r&1],k,j,i);}

You can remove the include and save another 18 chars, but then it doesn't compile without warnings.

Edit:
using user23241's command-line trick, the shortest C code that produces the result (without compiler warnings) is only 12 chars:

#include I
M

At least if you cheat and use the following command line to compile:

gcc -DI="<stdio.h>" -DM="main(){srand(time(0));char*o=\"O \",r=rand()%6,i=o[r<1],j=o[r<3],k=o[r<5];printf(\"-----\n|%c %c|\n|%c%c%c|\n|%c %c|\n-----\n\",i,j,k,o[r&1],k,j,i);}" dice.c -o dice

PHP:1284

This is my second CodeGolf, and I wasn't really aiming for shortness as much as code mutability and matching the gaming criteria.

You can generate 4 sided dice as well as 6 sided.

Maybe later I will shorten it and make it a little more dynamic.

function draw_dice($numdice=1,$sides=4)
{
/* Verify acceptable parameters. */
if($sides<4){die("You must choose 4 sides or greater.");}
if($numdice<1){die("You must have at least one dice.");}
/* End verification */
$a=' ';
$b=' ';
$c=' ';
$d=' ';
$e=' ';
$f=' ';
$g=' ';
$h=' ';
$i=' ';
$j=' ';

switch($sides)
{
case $sides%2==0:
if($sides==4)
{
$ran=rand(1,$sides);
switch($ran)
{
case 1:
$e="o";
break;
case 2:
$a="o";
$j="o";
break;
case 3:
$b="o";
$g="o";
$j="o";
break;
case 4:
$a="o";
$c="o";
$g="o";
$j="o";
break;
}
echo "<div style='text-align:center;display:inline-block;'>";
echo " - <br/>";
echo "| |<br/>";
echo "|$a$b$c|<br/>";
echo "| $d$e$f |<br/>";
echo "|  $g$h$i$j  |<br/>";
echo "---------<br/>";
echo "</div>";

}

if($sides==6)
{
$ran=rand(1,$sides);
switch($ran)
{
case 1:
$e="o";
break;
case 2:
$a="o";
$i="o";
break;
case 3:
$a="o";
$i="o";
$e="o";
break;
case 4:
$a="o";
$c="o";
$g="o";
$i="o";
break;
case 5:
$a="o";
$c="o";
$g="o";
$i="o";
$e="o";
break;
case 6:
$a="o";
$c="o";
$d="o";
$f="o";
$g="o";
$i="o";
break;
}
echo "-----<br/>";
echo "|$a$b$c|<br/>";
echo "|$d$e$f|<br/>";
echo "|$g$h$i|<br/>";
echo "-----<br/>";
}

if($sides!==4&&$sides!==6)
{
die("Only 4 and 6 sided are supported at this time.");
}

break;

case $sides%2==1:
die("Must have even number of sides.");
break;
}

}

draw_dice(1,4);

Output 4 sided:

    - 
   | |
  |o o|
 |     |
|  o  o  |
---------

Output 6 sided:

-----
|o  |
| o |
|  o|

Answer 30

VimScript – 169 chararacters

Note that this is not pure Vim since Vim has no builtin random number generator. There are extensions that can be downloaded for it of course, but since I am a diehard Linux man, I thought, why not just rely on the shell environment instead.

Code

norm5a-^[YPo|   |^[YPP
let x=system('echo $RANDOM')%6+1
if x<2
norm jllro
el
norm lrolljj.k
if x>3
norm k.hjj
en
if x>2
norm h.k
en
if x>5
norm .l
en
if x>4
norm l.
en
en

Explanation

• The first line generators the "box" that represents the die.
• The second line fetches a random number from the environment and using modular arithmetic forces it to be a valid number for a dice.
• The remaining lines move around the die face filling in the o 's. Note that this is meant to be optimized for the least number of characters, not the least number of movements (i.e. there would be faster ways in turns of keystrokes if I was doing it manually—doing the ifs all in my head).
• As always, ^ is not a literal ^ but an indication of an escape sequence.

Testing

Change RANDOM to DICEVALUE, save the VimScript code into dice.vim, then run this shell script on it, giving as arguments whatever numbers you want to test:

#!/bin/sh
for DICEVALUE in $@; do
    export DICEVALUE
    vim -S dice.vim
done
