Thread: How do you roll 1d2?

1. How do you roll 1d2?

Thing I learned today: the official method of rolling 1d2 is to roll any dice, with an odd number counting as 1 and an even number counting as 2. Rolling any dice and counting any number below half as 1 and any above as 2 is presented as an alternative. I've also been at a table where a guy flipped coins. I usually use the low-high method.

2. Re: How do you roll 1d2?

D4, halfed, rounded up. Or more generally, high/low on any die

3. Re: How do you roll 1d2?

I usually take a D6, low is 1 and high is 2, but you can use any die really. I prefer this over the odds/evens way.

A coin toss is also good but it has an annoying habit of either disappearing or going way further than a roll so it's more difficult to read and recover.

4. Re: How do you roll 1d2?

Roll a a dice any dice.

Over half value its a 2. Under, its a 1.

5. Re: How do you roll 1d2?

Eeny-meeny-miney-moe is a sensible choice.

6. Re: How do you roll 1d2?

Rock-paper-scissors, lose is 0, win is 1, shark mitt is chomp.

7. Re: How do you roll 1d2?

Flip a coin or use /r 1d2 if I'm in Roll20.

8. Re: How do you roll 1d2?

Personally I prefer rolling any die with "odds" as 1, and "evens" as 2.

9. Re: How do you roll 1d2?

Roll any dice

Odds is 1
Evens is 2

10. Re: How do you roll 1d2?

Roll a d12;

1-3: 2
4-5: 1
6-7: 2
8-11: 1
12: 2

It's as arbitrary as any other method, right?

11. Re: How do you roll 1d2?

Well, I'd most probably flip a coin or roll a d100 and treat it as a 50% chance.

Still, virtually any cannonical die cuts it, by either calling low-high, or odds-evens. Binary choices are the easy part.

12. Re: How do you roll 1d2?

Low-high.

But it would be fun to find one of those:

13. Re: How do you roll 1d2?

I used to have a coin with 1 painted on one side and 2 painted on two side the other. But we use d2 ro rarely I don't know what became of it.
Now I use low 1, high 2 on whatever die is to hand.

14. Re: How do you roll 1d2?

I superposition a 1 and a 2 and let the probabilities sort it out.

*hardy har har, I amuse myself

I typically use the d6 method. But honestly, I'm having trouble coming up with times I've actually needed a d2 in play and can't think of any off hand, I say the d6 method because the d3 was relatively common in AD&D

15. Re: How do you roll 1d2?

I'm a fan of the d4 halved rounded up method, functionally equivalent to 'roll die, below half = 1, above half = 2' but I find using a caltropd4 means that I'm just that little bit less likely to forget that it's a d2 rather than a d3 or a d5 (I've used all of them before, I think once all appeared in the same system). I also once used this when I grabbed a d12 when I meant to use a d6, I think, it was years ago if it happened.

16. Re: How do you roll 1d2?

For years, I kept a 100 peso coin in my dice bag for this kind of roll, heads = 1, tails = 2.
Now, I just grab a die and go hi/low

17. Re: How do you roll 1d2?

Impregnate someone, wait nine months female =1 male =2 on twins, reroll.

That's not equivalent to a fair coin flip. Your statistics will be off by about 1% to say nothing of the coin landing on edge or any individual biases one way or another.

19. Re: How do you roll 1d2?

Low high.

Usually on a D6 because those are easy to read quickly.

20. Re: How do you roll 1d2?

Roll 14d6, if the number of even rolls is even then the result is even.

I think there may be some kind of weird bias though because most of the time I don't even.

21. Re: How do you roll 1d2?

odds or evens on a d7. Because why play, when you can just be odd(s)?

22. Re: How do you roll 1d2?

I flip a coin.
My wife picked up this Loot Crate that had a big Assassin's Creed coin. I keep that with my dice for 1d2 rolls or to use as a reminder when I have used my reaction during a round. that coin actually gets used for a lot each session.

Actually there a lot of my wife's trinkets that get used as props or minis during game...I know I was running one undead themed dungeon crawl and I used some of her make-up containers, perfume bottles and such as props (she has a lot of Kat Von D and several of those bottles are skull shaped in different colors, some are close to "medium" and some "large" game sized) I have used them for dungeon furnishings and once for undead beholders.

And now I am on a pain-killer infused rambling spree...so maybe nap time

23. Re: How do you roll 1d2?

The troll comments here are pure gold.

Anyways I use a coin.

24. Re: How do you roll 1d2?

I generally flip a coin. I even have a really nice pokemon coin to flip. X3

What if the twins are both the same sex?

I also assume you have a few women ready for when you need to roll multiple d2s at once? A friend of mine once had to, and unfortunately he used to get his dice from the local pub...

26. Re: How do you roll 1d2?

d6 high low.

There's a player at one table who struggles with this. "But I rolled a 6!"

Roll 1d6, even is 2 odd is 1. Been doing that for quite a while. Coin flip also works.

@itreeby: LOL.

28. Re: How do you roll 1d2?

I flip a coin.

29. Re: How do you roll 1d2?

I take two beers from the fridge, shake one up, mix them up and hand it to the player. If it explodes I laugh. If not, he rolled a 2.

30. Re: How do you roll 1d2?

I have a small cardboard cutout with little flaps covering numbers: two ones and one two. When we need to roll a d2, the rolling player picks a door, and then I reveal one of the doors with a one behind it (but not the one that the player picked). The player gets to decide whether he or she wants to switch doors or keep their first choice.
