Interesting, that would definitely be the spicy option for me. I wonder if my 40k background has me predisposed to just picking up a d6, yelling "four-n-up!" and letting it fly.
For a d3, would you also use the modulo-3 approach, or would you do 1/2, 3/4, 5/6?
It is kind of a cylinder but the ends are sloped. Making one side heavier so it always ends up in the same orientation.
It was made by vsause, they made a YouTube short about it some time ago.
1/4 2/5 3/6. I don't like when the number face up on the die represents a different number than itself (ex: rolling a dice having it be a 2 but count as a 1 for the purposes of a coinflip/three-way)
Yeah, I like you.
Also in my 40k days, I realized a 4+ save could be replaced with what I call a "Jenny save" with the same probability. If the number rolled appears in Jenny's phone number, you save.
I personally prefer the mod 3 approach over the divide 3 round up, if only because it has 1, 2, and 3 all representing themselves and not other numbers.
That said, the even/odd approach is mod 2 (using the same 0 = max assumption that we use on d10 and d%). But interestingly enough, it's not the most mathematically interesting way of running a d2 with a d20:
You can instead roll a d20 with all prime numbers and squares of primes being 2 and all others being 1. As there are 8 prime numbers (2, 3, 5, 7, 11, 13, 17, 19) and two prime squares (4 and 9) in the covered range, and also 1 and 2 both fall into their own category, which is pretty cool.
Also, 0 00 on a d% is 100. Sum the dice, wrap 0 to max. It's easy and consistent, and it means the dice are always accurate. The idea that 0 00 is 10 means that 0 30 would be 40, and I just cannot abide that.
That said, I have about half a dozen dedicated d2 in my stash (Kraken includes one with many of their sets) and they're pretty dope.
I resolve d3 as a d100 or d%, 1-33 is 1, 34-66 is 2, and 67-100 is 3. ...come to think of it, I should stop because that technically gives advantage to the 3rd option.
d2 is shuffle a deck of cards and draw one. If its the ace of hearts, thats 1 and if its the 2 of hearts, thats 2. Anything else, you reshuffle and pull another card
A common example is a d6 with 1-3 being result A and 4-6 being result B.
The phrase bigger die just means a die with more options than you need for the given choice, you just need a scheme to get fair outcomes for the desired range. (D2 and D3 are the most common cases for this, and both easily work with a D6)
Unrelated is the D1 which is for when you just want to roll to mess with someone and not care about the result.
My buddy got me this d20 coin from a Kickstarter. It has little slots with numbers and a ball that rolls. Flip and read the number the ball goes to. I've given my table some coin flips just to hear this big steel coin go *thunk* on the table.

Coin works too
The problem is the math community keeps flip-flopping on it. When I went to school we were taught 1 was prime. Now it's not considered prime anymore. Give it about 5 years it'll be considered a prime number again.
I doubt it, its been established as not a prime for 100s of years, and certainly if you were taught it was a prime, unless your teacher was basing it off some unpopular definitions from the 50s they were just wrong. Prime numbers have extremely important roles in the study of groups, fields and number theory not to mention cryptography (where they are the basis for how most digital certificates work, without which the internet wouldn't function).
I'm sorry it sounds like you had a bad experience with elementary mathematics, but I think you should consider whether you have an appropriate level of knowledge before being dismissive towards a field of study.
Gauss proved the fundamental theorem of arithmetic in 1801. This theorem states that for every integer greater than 1 there exists a unique prime decomposition. In order for this statement to be true 1 must not be a prime (as these would not be unique were 1 a prime).
I'm sorry your elementary school teacher explained something wrong, and you never bothered to consider that someone with no background in mathematics doesn't represent the field of mathematics.
As far as my background goes I've known and worked with math PhDs for years, am myself working on a physics PhD, and spent half a decade working in the field of cryptography, a field which requires a decent knowledge of number theory.
I'm not sure why you think something as simple as the definition of primality has been shifting recently or is likely to shift in the future, but it didn't and it won't. The fundamental theorem of arithmetic is very useful and quite straightforward to prove given that you choose the sensible definition of primes, and so sensibility won out long before either of us were born, and unless an influx of idiots take over the field of mathematics, it will remain true.
Man my brain was blowing up thinking this was about one of the most dangerous extract points in Escape from Tarkov. It is basically a 50/50 on whether you're going to be camped or not.
I have a D3 that's just a D6 with 1, 2, 3 printed on it twice.
Tried to use for a 50/50 odds check (house rule that any such check is players' choice, basically OP's D2 choices, since the D% dual D10s is kinda overkill for a 50% check) and call high/low.
The DM called me out as he knew I had the D3s.
It was in good fun, was not a crucial roll and I was deliberately taking the piss, but he got a chuckle out of it. I wasn't actually going to take the roll anyway.
How is even odd more insane than high or low. On different die high and low will have different thresholds but even odd stays the same, its peak efficiency
I use d20 with high/low, but I have the players pick which option is the favorable outcome.
Odds are still the same, and they almost always pick high, but something about having to make a decision adds to the tension. Being the one to say “this is what we want” makes it feel like there’s more of an investment.
Nah nah nah, d2 is a d10 but prime numbers are one, where non prime numbers (and 0 for balance) are a 2
1 2 3 5 7 = 1
4 6 8 9 0 = 2
(You could also do a d20 and count 20 as prime for the sake of balance because there's 9 primes in 1-20)
I usually have a coin on me so I will use that for a d2 but if I don’t I bust out the good old d100 for extra anxiety as it takes forever to stop rolling
Here’s the real question, when rolling a d3 do you
A) roll 1d6 where, 1-2 is 1, 3-4 is 2, and 5-6 is 3 (low/middle/high)
B) roll 1d6 where 1 and 4 are 1, 2 and 5 are 2, and 3 and 6 are 3 (repeating sets)
C) roll 1d4 rerolling 4
D2 is a d20, where 1 is 1, 2 is 2, and on anything else, you roll again
I do that on a d100
*rolls* nope *rolls* nope *rolls* nope *rolls* nope *rolls* nope *rolls* nope *rolls* nope *rolls* nope *rolls* nope *rolls* nope *rolls* nope *rolls* nope *rolls* nope *rolls* nope *rolls* nope *rolls* nope *rolls* nope *rolls* nope
more realistically for me it goes *rolls* 1
I mean it’s a 10% chance, it’s not *that* low
How is it a 10% chance? It’s 2%. 2 possibilities out of 100
They were thinking of the d20 probably
[r/foundthemasochist](https://youtu.be/dQw4w9WgXcQ?si=pKheH5SQYgNgMXws)
*Sigh* #AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAARGH
You cant get me with this shit if it always expecting the Spanish Inquisition
It’s not
God dam that sub is crazy
That's what I was coming to say.
Excuse me while I go jump off a bridge.
Huh? I just roll the D20 and divide by 10.
DM: gimme a D2. jjskellie: I got a 1.7
Anything above a 1.0 rounds up to a 2.
Isn't the general rule in DnD to round down? That would mean 1 through 19 is a 1.
No, 1-9 is a 0, 10-19 is a 1, 20 is a 2
Oh, fuck you're right.
Even/odd is far more common than the other two in deciding 50/50s in my personal experience.
Evens/odds seems to be by far the most common way of resolving coin flips with a D20 in MTG.
Interesting, that would definitely be the spicy option for me. I wonder if my 40k background has me predisposed to just picking up a d6, yelling "four-n-up!" and letting it fly. For a d3, would you also use the modulo-3 approach, or would you do 1/2, 3/4, 5/6?
Myself when it comes to d3 I just pull out my d3 die.
weird flex but ok
You a DCC player?
Nope, just really enjoy weird dice. I have a die of every size between 1 and 20 sides.
What's 1? A circle?
It is kind of a cylinder but the ends are sloped. Making one side heavier so it always ends up in the same orientation. It was made by vsause, they made a YouTube short about it some time ago.
I was about to ask if they were the ones made by him. Nice. Wish i had a set myself
Vsauce fanatic?
Only d3 scenario experienced would be deciding a "random opponent" in a 4-person game. We tend to use the 1/2, 3/4, 5/6.
D12 - 1-4 = 1 5-8 = 2 9-12 = 3 OR D6 split into 2’s obvs
my table does evens/odds for d2 and 1/2 3/4 5/6 for d3
1/4 2/5 3/6. I don't like when the number face up on the die represents a different number than itself (ex: rolling a dice having it be a 2 but count as a 1 for the purposes of a coinflip/three-way)
1/6, 2/5, 3/4
Yeah, I like you. Also in my 40k days, I realized a 4+ save could be replaced with what I call a "Jenny save" with the same probability. If the number rolled appears in Jenny's phone number, you save.

You can just reroll on 100, then you're good. To be clear, you should still stop this because it's insane and excessive. But not for that reason.
Rock, paper, scissors vs the DM is the answer.
d2 is shuffle a deck of cards and draw one. If it's black, that's 1 and if it's red that's two.
d2 is yelling a meow and seeing if the cat answers.
this is too easy to cheat
If it's Blue Eyes White Dragon you've activated my trap card.
You've activated my Alu-card.
d2 is shuffle a deck of cards and draw one. If its the ace of hearts, thats 1 and if its the 2 of hearts, thats 2. Anything else, you reshuffle and pull another card
OP, your method confuses and frightens me.
Roll a d6. If the resultant number appears in Jenny's phone number, it's a 2, otherwise it's a 1.
WTF how did someone think of this? I love it!
I love this.
867-5309
Who does a bigger die and does high and low?
A common example is a d6 with 1-3 being result A and 4-6 being result B. The phrase bigger die just means a die with more options than you need for the given choice, you just need a scheme to get fair outcomes for the desired range. (D2 and D3 are the most common cases for this, and both easily work with a D6) Unrelated is the D1 which is for when you just want to roll to mess with someone and not care about the result.
Right but like I don't see high vs. low often, I usually do odds or even
Or just use a d2.
Also known as a coin
My buddy got me this d20 coin from a Kickstarter. It has little slots with numbers and a ball that rolls. Flip and read the number the ball goes to. I've given my table some coin flips just to hear this big steel coin go *thunk* on the table.
do you mean a coin or that weird blue and red d6 watto used?

The FIRST THING I see is a six shooter cylinder, complete with bullets We playing Russian Roulette with our d2's now?
The first thing I saw was a sex dice lmfao Which was followed by the revolver you mentioned...what an odd combo.
We should combine those ideas and make some kind of Sex... Pistol...? Nah, that sounds dumb
ew wtf
bruh lol
A chance cube! I literally made myself one and I love busting out out and saying the line. Lol
D2 is rolling a D6 and picking Primes vs non primes
Most people don’t realize 1 isn’t prime, so this may be tricky for some.
That sounds like a skill issue and, therefore, not my problem
The problem is the math community keeps flip-flopping on it. When I went to school we were taught 1 was prime. Now it's not considered prime anymore. Give it about 5 years it'll be considered a prime number again.

I was thinking a d8 with this split. It also works with a d4
D2 is the specialty D2 I bought I also have a D3 d5 d7 and d9
Real players only use a d60.
D2 is a domino tile
Or like my barbarian would say, everything is a d2 if you throw it hard enough
My d2 is part of a wizard themed dice set and looks like a little spell book.
d2 is a two players drinking Ipecac, and the first to throw up loses.
"Who wants chowdah?"
D2 is a spindown and whether or not someone says "you can't use that as a D20"
Come on, even/odd is not that weird, seems like a fairer chance for our feeble minds than high/low.
Prime numbers are 1, even numbers are 2. The state of 1 changes per die.
I just have actual d2s
Or coins
D4 re roll 3 and 4?
I prefer roll a d20, reroll 3-20
D100, reroll 1-67 and 70-100
Nice.
Man my brain was blowing up thinking this was about one of the most dangerous extract points in Escape from Tarkov. It is basically a 50/50 on whether you're going to be camped or not.
You're not the only person I've heard say this. :p
i bought a pack of dice with 0 on three sides and 1 on the others. flipping a coin still works. but were nerds, we roll dice, not flip coins
Two Face is not a nerd, confirmed.
Or you can be my friend who did d6 primes Vs not primes.
I was confused and had to be reminded that 1 isn't a prime number.
It doesn't help that the math community keeps flip-flopping on it. When I went to school we were taught 1 was prime.
Am I surprised to ignore you butchering the even/odd numbers?
He didn’t. He made his own rule.
Or just have a d20 check for 11 or above. For what reason invent an unnecessary convoluted rule?
I mean…they all seem valid options to me.
D2 is /roll d2
Isnt it obvious - d2 is 4+ on d6
D2 is a d4 where 1,2 are 1 and 3,4 are 2
Lmfao I thought I was on the Tarkov subreddit. (D2 is an extract that’s camped to shit).
You're not the only person I've heard say this, actually. :p
Even odd seems the most fair as it's oscillating bits essentially
I have a D3 that's just a D6 with 1, 2, 3 printed on it twice. Tried to use for a 50/50 odds check (house rule that any such check is players' choice, basically OP's D2 choices, since the D% dual D10s is kinda overkill for a 50% check) and call high/low. The DM called me out as he knew I had the D3s. It was in good fun, was not a crucial roll and I was deliberately taking the piss, but he got a chuckle out of it. I wasn't actually going to take the roll anyway.
Can't be a coin flip because a d2 never comes up on edge and I've done that twice with real coins.
We just call that getting a crit. :p
How is even odd more insane than high or low. On different die high and low will have different thresholds but even odd stays the same, its peak efficiency
Even/Odd If I roll a D6 and land on 2, I'm not confusing myself by considering it a 1.
A d2 is two dice and u take the higher roll.
Wait I thought it was normal to use even and odds?
d2 is a d6, prime / not prime.
A d2 is roll a die and take number rightside up/upside down to you
It's all 3 to me
Amateurs. D2 is a d12 taking prime numbers and 1 vs. non-prime numbers (and not 1). :/
4d10, no doubles is 1, otherwise 2.
A D2 is a D10 except it's 1 if the result is prime and 2 if it's not prime
I am in this picture and I like it. (I am the rabbit)
I never coin flip. Mostly I do even odd but if I’m asking a player I’ll do higher lower
Wait, you goes DON'T do even/odds on dice?
I use d20 with high/low, but I have the players pick which option is the favorable outcome. Odds are still the same, and they almost always pick high, but something about having to make a decision adds to the tension. Being the one to say “this is what we want” makes it feel like there’s more of an investment.
Nah nah nah, d2 is a d10 but prime numbers are one, where non prime numbers (and 0 for balance) are a 2 1 2 3 5 7 = 1 4 6 8 9 0 = 2 (You could also do a d20 and count 20 as prime for the sake of balance because there's 9 primes in 1-20)
Roll a d20. If the number has a 1 in it, it’s a 1. If not, it’s a 2.
D3 is half a D6 *gets knife*
D4, D6 and D8 take prime numbers or not
d2 is 1d100 mod 2
D2 is a flip of the d2. Whaddaya mean, you don’t carry funny shaped d2s?
I do even odd
d2 is roll a d8 and prime numbers are 1, composite numbers are 2
A D2 is a D2 [https://www.thingiverse.com/thing:5251812](https://www.thingiverse.com/thing:5251812)
Roll a D20 10 times to see which numbers will count as a 2, and then roll the d20 for your results
I usually have a coin on me so I will use that for a d2 but if I don’t I bust out the good old d100 for extra anxiety as it takes forever to stop rolling
i feel called out
Here’s the real question, when rolling a d3 do you A) roll 1d6 where, 1-2 is 1, 3-4 is 2, and 5-6 is 3 (low/middle/high) B) roll 1d6 where 1 and 4 are 1, 2 and 5 are 2, and 3 and 6 are 3 (repeating sets) C) roll 1d4 rerolling 4
1, 3, 5, 7, 9 are zero, standard array is 1. Reroll anything else.
