So this happened at the bng prerelease and I wanted your input on it. When determing who went first everyone refused to roll a d20, in favor of two d6. Their claim was "it's more random". I could never get a straight answer out of anyone why, nor could I calculate how they came to this. To me it just seems more likely to result in a tie. Maybe everyone just copied the owner since that's what he did. Anyone have an idea of what I'm missing?

Some people don't like to roll spindown d20s because "someone can learn to roll them for a high number each time" or something equally inane. As to the randomness claim, that's just wrong. There are 36 permutations for 2d6, but there are only 10 numbers you can get. That's half the options of a d20, because permutations don't matter, no one is betting they'll go first on a hard eight.

This is probably because those people are crazy, but assuming you have ordinary chessex type dice the d20 is less random (at an incredibly marginal, statistical level irrelevant to rolling for going first in a game of magic) than ordinary chessex style d6s because the problematic manufacturing process is magnified more with more faces. Unless your opponents were pulling out casino grade d6s as their response they're just crazy. That said I have to include the unless since I ran into a guy with a 4 digit DCI number who pulled out a pair of casino grade d6s to determine who goes first at my prerelease.

You'll come across people specifically that don't want to roll the spindown dice, cause if you wanna get anal about it that's not a D20. Your average dice are made to where opposite sides always add up to the same sum. Like on a D6 any two given opposite sides should always add up to seven. That kind of distribution makes it so that there aren't a bunch of high or low numbers clustered together on touching or nearby faces, which would effectively make one side or area higher than average and the other lower. Spindowns aren't like this because they count down sequentially so they're exactly like what I just said; one hemisphere is really high and the other is low. In theory someone could hold and throw the dice in such a way to deliberately hit the high side, and in reality nobody's gonna be able to. It's just something that makes everyone feel better that has a really tiny bit of logic behind it.

The spindown thing has a small grain of truth to it. Spindowns aren't weighted evenly and tend to roll higher numbers, on average, than a a standard d20. It shouldn't matter when you are rolling off against someone, because your chance of rolling any one number is the same as theirs.

But spindown d20s aren't 'proper' d20s, since the numbers are sequential (19 adjacent to 20 etc), and the sums of opposite sides don't add up to 21, as it should be. With how common a 'proper' d20 is in a gaming store, why not just roll one of those, I personally won't roll a spindown if I can avoid it. Kinda , apologies about that.

It does have a small grain of truth, but honestly if anyone at your LGS can reliably throw a spindown for 17+ or something like that they should be on a craps table and not at a prerelease. Coin flips are always a decent go to, and I'm not averse to the coin flip options in some of the phone apps. I did have one guy at my LGS decline the app flip because "he's a software dev and knows those aren't truly random." which always felt a lot like the spindown argument to me. Just find a fair way to determine who goes first, even if it isn't random. Fairness is much more important.

Maybe everyone just copied the owner since that's what he did. Anyone have an idea of what I'm missing? It's actually significantly less random because simply adding multiple dice together gives you a bell curve distribution of results where the average result is much more likely than an extreme result on one end or the other, where using a single D20 has an equal probability of rolling each result. 2D6 is adequate for something like "who goes first" because it's still 50/50, but you're going to see more ties and rerolls than with 1D20. I think they're getting a D20 and a spindown counter confused. Spindowns should never be rolled to determine a random result; they're much easier to coax into getting near a certain result because all the lumbers are next to each other.

Just get them to call even or odd and roll any die. Of course there are some D8s or D10s or whatever that have all the odd numbers on one side and all the evens on the other...

This is a really awesome post about the randomness of Chessex and Game Science d20s: https://www.awesomedice.com/blog/353/d20-dice-randomness-test-chessex-vs-gamescience/ Basically, a d20 from either company isn't truly random, but the margin from true randomness is so small that it doesn't matter for tabletop games or deciding who goes first in magic. Also, anybody who won't trust a program because it's only pseudorandom doesn't understand why it matters that it's different from random.

Me and my friends usually roll the two d10 percentile dice to determine who goes first. It makes it a lot less likely to get duplicates in a 4-8 player EDH game.

The only thing to worry about isn't that the number you're getting isn't really ~random~, it's that your opponent is using something that sets its RNG seed once and he or she knows the pattern. I could write a little app that sets its RNG based on a defined number and memorize that number pattern a certain distance out, but anything that sets its RNG again based on the system clock on each call for a random number (which I assume a dice-rolling app will do) is nigh-impossible to game. Besides, at some point you have to accept that your opponent isn't a weirdo creep out to eek a tiny advantage out of the dice roll and just wants to play some magic.

Definitely, if someone prefers to roll 2d6 or whatever I'll go with it. It's faster to use their correct method of randomness than to try to explain to them why my method of randomness is, for all effective purposes, equally correct.

Since I'm not a D&D player and I prefer to keep track of life on paper, I don't own any d20s. I don't object to using a d20 to roll, but I have d6s available for counters and other things, so I default to those.

Cockatrice, the free MtG client, has a really, really bad RNG -- in my experience it shits itself if you try and roll a d2 (for a coin flip) and it's way better to roll a d20 and just call odds or evens. I know this is totally anecdotal and could be a freak occurrence but an opponent and I sat there rolling d2s back and forth for a minute and I rolled ten 1s and he rolled ten 2s. Whatever algorithm they use seems seriously hosed
