1. Does anyone have any experience with "two-sided" dice in games like Burning Wheel or Storming the Wizard's Tower? Not actual two-sided dice (ie - coins), but six-sided dice marked with two symbols repeated three times ... three skulls and three lightning bolts, for example.

It seems like this might be a little easier to use than regular six-sided dice for games where the number of successes matter, rather than the totals. I guess if you play those games a lot, counting the successes becomes second nature, but if you don't, it can be a little tedious.

I realize this won't always do the trick for those specific games, as it defeats things like open-ended rolls. Just curious if anyone had used dice like this in a game.

2. If anyone has played with dice like this, where did you get them? I can't seem to find any online.

3. For games using Fudge dice, how do the probablities stack up against straight rolls, or dice pools? is there any benefit to rolling larger numbers of dice for a skill-based conflict, if higher numbers simply create more negatives as well as positives?

2. I have never seen dice like this. They're of such limited use, I can't imagine I'd drop 15-20 bucks for a cube of 12mm "two-siders."

3. Again, I'm not sure what you're asking. Fudge dice are d3's, essentially, but with a -2 modifier. 4dF is 4d3-8. At handfuls of more than about 4 Fudge dice, the chance of maxing out on one end of the curve is almost negligible (1 in 3^N, where N is the number of Fudge dice). So the chance of maxing out pluses with 4dF is about 4%; 5dF = 1.2%; 6dF = 0.4%; 7dF = 0.1%; 8dF = 0.02%... So while you can increase the range, the chance of actually rolling anything on one end of the range is very, very small.

Yes, the mean result of Fudge dice never changes -- it is always 0.

Edit: Oooh, Kaplow makes binary dice (three 0's, three 1's). And they even sell them on Amazon.

Special Burning Wheel dice have been made (I think there's even a thread here on them). There has been discussion of the most cost effective way of making them, to be pure, they need 5 different face markings (equivalent to 1, 2, 3, 4 and 5, 6). It is possible to do with 4 unique markings, A, B, B, C, C, D, however, while A can consistently be treated as a "6" for exploding dice, D, can not always be treated as a failure (for black shade, C and D are failure, for grey shade, C is failure, for white shade, D is failure).

s = sqrt(N) * 0.816

z = (X - 0.5) / s

look up z in a table of z-scores for normal distributions, like here: (http://www.epatric.com/documentation/statistics/z-score_table.html). If your percentile is e.g. 90th, that's a 10% chance.

Example: how likely am I to get a 3+ on 8 dice? X=3, N=8. s=2.3, z=2.5/2.3=1.1. Looking up z=1.1 I find the table says "0.8643", which means there's an 86% chance of getting lower than a "2.5", giving about a 14% chance of getting a 3+. The bit where we subtract 0.5 is to deal with all the numbers between 2 and 3 that the dice might roll... they can't, obviously, but the distribution thinks they can, so we just throw all the 2.5-3 results in with 3+.

Getting -X or worse is the same chance as getting +X or better, of course.

I'm aware that binary dice don't work for Burning Wheel specifically, since the 6s are open-ended rolls (and since differing shades have non-binary success numbers). It was just the first game that came to mind where you roll many d6s and count the successes.

My question was if anyone had any experience using two-sided dice in systems that DON'T have such factors. I haven't heard of Mythender, but I'll look for it.

Peter, thanks for the heads-up. Those are indeed the kinds of dice I as looking for.

Although I'm a little disappointed in the available flavors. Xs and pluses and colored sides all do the job, but I was envisioning skulls and fists, or something similarly dramatic.

- 0,0,0,0,1,1,1,1
- 0,0,1,1,1,1,2,2
- 0,1,1,1,2,2,2,3

The first typeisa D2, the second is equivalent to rolling 2D2, and the third is equivalent to rolling 3D2. They're supposed to be nice for dealing with large pools of D2 -- I've heard mention of them being used for Prince Valiant on rpg.net, as well as Exile Game's own Hollow Earth Expedition RPG.Edited:

Annnndcross-posted with Wilhelm...But then how would you know you were role-playing? I don't understand.

I think the venerable

Story Engineuses what amount to D2's counting "odds" as they put it.Ryan, was this the reasoning behind your choice to use these dice in your game? Or are you just using plain ol' d6s? I do see the value in open-ended rolls, like BW's. Is that something you felt your game didn't need? (Efindel, those questions would apply to your game as well).
