Talk:Dice notation

message: Do any actual games use the Low/high roll notation, or is that section a cheeky advert for the die roller?  Percy Snoodle 15:06, 10 July 2006 (UTC)
replies: text: There are game systems that allow for the dropping of the lowest die—or dice— of a roll, but I have never seen them note the roll like 3d6-L. I have never seen a system that uses either the +H notation, or the mechanic it describes.<BR />—Asatruer 18:14, 10 July 2006 (UTC)
replies: text: It is at least not meant as an advert for the die roller. But I would think since this notation is in actual use (if only in that die roller) this is not really “original research”. Might be a boarderline case, though. --TowerDragon 23:53, 28 July 2006 (UTC)
replies: text: I would suggest to open an item about this: most rules and written materials about dice use quite simple notation and further manipulation is just described by words, like "4d6 drop lowest". The need for more detailed formulae is only needed for computerised things, like online die rollers. There, players may be compelled to actually translate "4d6 drop lowest" to "4D6-L" or so. Then, two families of notations do exist: a mix of words/formulae in most written rules and players vocabulary, and a more complex one for the computer world (aka dice rollers, online or not online). Further more, since availability of complex notation and online systems permit almost unlimited kind of dice, I see more and more players using very special dice (like 3d6-2d6 for attack minus defense, or combinaisons of different dice size in a throw), including things like d7 or d128 or multiple throws and tests, notably for war games. I don't post this directly, since I could be biased as webmaster of a die roller (one with many actual dice pictures), and statistics may differ for different tools.--Anyplace (talk) 22:59, 6 February 2009 (UTC)

thread_title:  D66 

message: I've cleaned up the beginning a little. Since there are a few changes, I'll motivate them here: I have never seen the notation 3d6+ and do not see the point in using it. I don't see the need to define B as a natural number; it should be clear what 3d6+1.5 means, even if it is never used in practice. (We don't need to be that formal here.) Also, repetition is not the same thing as recursion. Furthermore, I think the text is easier to read if the examples are broken up a little. Finally, I have never seen anything like 2d10+1d6-3 anywhere so I'm also changing that example somewhat. --Maggu 19:02, 30 August 2006 (UTC)
replies: text: That’s all OK with me. Just one thing: “repetition is not the same thing as recursion” — This is a case of tail recursion which is equivalent to repetition (iteration). (Writing the basic notation with modifier in Extended Backus–Naur form can make this clear: die-roll=N."d".N.[("+"|"−").(die-roll | Y)]; or, equivalently, die-roll=N."d".N.{("+"|"−").N."d".N}.[("+"|"−").Y]; where N is a natural number, and Y is an arbitrary number.) But as you said: “We don't need to be that formal here.” :-) — TowerDragon 19:58, 31 August 2006 (UTC)

message: I added a reference to d666 from In Nomine under six-sided variations.
This article seems to me to be of a good standard - should it perhaps be removed from the portal as requiring expansion?

thread_title:  Minor addition 

message: This is the section for discussion for merging D66 (die) into this page.
It is pretty clear to me that everything mentioned in D66 could be put into Dice notation by adding, oh, about a dozen words to the existing section on D66 in the D% section. Nezzadar (talk) 21:17, 1 September 2009 (UTC)
replies: text: Agreed, NN usage, no references, can be safely merged here per WP:NNC. Jclemens (talk) 22:28, 1 September 2009 (UTC)

message: *3 x (2d6+4) means "roll two 6-sided dice adding four to result, repeat the roll 3 times adding the results together."
For my curiosity: why wouldn't you write that as 6d6 + 12? —Tamfang (talk) 01:46, 3 May 2010 (UTC)
replies: text: Yes, it is a bad example.  A better example would be one which discards lowest or highest in each set of two:  e·g discarding the lowest in three sets { {1,2},{3,4},{1,6} } returns {2,4,6} but discarding the lowest three in one set {1,1,2,3,4,6} is {3,4,6}. — JamesEG (talk) 18:55, 24 March 2020 (UTC)
thread_title:  multiplication and addition 

message: Under the Percentile dice (d%) section, it says it is more uniformly random to roll two ten-sided dice than to roll a 100-sided die. How is this true? A 100-sided die should clearly have 1/100 chance of each number unless the die is incorrectly weighted. And two ten-sided dice rolled together also have 1/100 chance for each number.

replies: text: For a die to be fair in all conditions, its faces must all be equivalent under some symmetry group.  That's true of the common d10 but not of Zocchi's d100. —Tamfang (talk) 07:54, 18 February 2015 (UTC)

message: I think I remember encountering a notation variant where the D was replaced by a die or cube symbol, e.g. 3🎲6. Is that common enough to deserve a mention here? — Christoph Päper 22:23, 20 March 2017 (UTC)
