They are awesome, but the D12 and D20 tend to roll off things.

yeah, the d34 that I have has that same problem. Though at least it tends to roll in a circle.

I have to ask, what situation requires a roll of a d34?

Are you supposed to spin those dice (including Crumb's) like a top?

Megatron: The Danish lottery.

slim: You can roll them as you would normal dice. Some D34 dice are like two 17-edged tops back to back - you have to roll them as spinning them would immediately exclude the 17 'bottom' numbers.

And I must ask you, what situation could not be improved with a few rolls of a d34?

Default Re: Is it just me or are these dice messed up?

Nontransitive dice are really messed up:

Let's limit ourselves to normal six-sided dice. We have three dice with the following numbers on their faces:

A: 2,2,4,4,9,9
B: 1,1,6,6,8,8
C: 3,3,5,5,7,7

Each die is 'fair' in that it is symmetrical and evenly weighted - in the long run it will land on each face equally often.

Now we're going to have a competition - we each choose one die and then roll them - whoever rolls the highest number will win one dollar from the other player. Then we can choose again - we're going to repeat this one hundred times before the game is over.

I generously let you always make first choice, so that you can choose the die that you think stands the best chance of winning - you can change your choice each time or stick with the same die if you prefer.

The amazing fact is that this is a sucker game - whichever die you choose I can choose another one that will (in the long run) win me money.

A beats B 5/9 of the time.
B beats C 5/9 of the time.
C beats A 5/9 of the time.

So in our 100-roll match, I would expect to win about 56 of the rolls and only lose 44 meaning I would expect to take about $12 from you. :)

Default Re: Is it just me or are these dice messed up?

I was thinking about dice today. What is the chance I will roll a 1 on a single D6 if I roll it once? That seems simple enough: 1 in 6, or 16.66%.
Okay, but how do the odds change as I add more rolls or more D6?
What if I roll 2d6- what is the chance I will roll a 1?
Aren't the odds higher?
2 out of the 12 possible faces result in 1.
2:12 is 1:6 is 16.66%.
Math fail.
That doesn't seem right.
What if I roll 4D6, or 10D6? or 100D6? Seems like my odds of a 1 showing up out of the total rolls come close to 100% very quickly. Is there a calculation I should be making for each additional roll?
Any statisticians, bookies, or math-abled bodies out there?

I freely admit that my education in math extends to a pity "D" in high-school geometry along with an admonition to not return.

There are 36 possible results for 2D6. Six of them involve a 1 on the first die, six have a 1 on the second die. But there is overlap at 1 on both. So there are 11 results with at least a single 1 out of 36 possible rolls. 11/36 = 30.35%

Default Re: Is it just me or are these dice messed up?

Generally, the chance of rolling at least one 1 on N D6 is 1 - (the chance of rolling no 1s at all). The latter term is (chance of rolling no 1 on die 1) * (chance of rolling no 1 on die 2) * ... * (chance of rolling no 1 on die N) = (5/6)N

So you end up with 1 - (5/6)N

In the case of N=2 this is equal to 1 - 25/36 = (36-25)/36 = 11/36, or what Crumb said.

Default Re: Is it just me or are these dice messed up?

Out of the 36 possible results of rolling two dice, there's only one way of getting a total of two spots, and only one way of getting a total of twelve spots.

The easiest number of spots to roll is seven - there are six different ways to do it. So in the long run, you will roll 7 six times as often as 2 or 12.

In some games where you're moving a counter around based on the throw of dice and you sometimes get the option to throw again or not (based on a bonus card or similar) then the knowledge of the likely totals from a pair of dice can help your strategy - remember that you're much more likely to throw middling numbers like 6, 7, or 8 than extreme numbers like 2 or 12 - and then you can look at the squares you're most likely to land on and decide whether they are good or bad...
