I have *never* heard of someone adding up the two dice rolls so that a 70 + 0 roll = 80. I feel like I took a trip to crazy town.

[chrisquinn]

i think its easier just to go with all zeroes are zero unless you get tripple for the 100

[GeekPhilosophy]

Too funny! I have recently had to explain the whole d100 situation to my players. We decided on the very older school method of using two different colored regular d10s. For example, we use one red d10 and one blue d10. Assign the tens digit color before rolling. It has made life much simpler :) Thanks for the video!

When someone told me about the addition version before, I saw the logic of it. I'm still going to use the legacy version, but I can see the opposing view.

[krismueller]

Those who I know from Old DnD (70s) simply would get a d100 instead of 2d10, and this problem wasn't a problem.
I loved playing with it as a kid, it was like a large golf ball and so much fun.

Can i just say how refreshing it is to hear someone who has Actually figured it out. I spent years arguing with an old DM about how rolling d100's work...dude couldn't get it throught his head that his weird way there's exactly no ways to get a roll of 1-100

[diegorodrigues]

I just go for the logic. Both generate 1 to 100. The so called legacy version is a lot more intuitive

[billwhipple]

I hope you keep putting these out. They are informative and to the point

I was actually thinking "what's a percentile dice" when you answered it for me! BIG WOW!!!! How do you only have 44 subscribers and not 44 million?!?!?! I'm glad I was here when you started it all!

[grogthing]

it is clear to me .. and you even read it from the book .. dice are numbered from 0 to 9 .. so zero is not equal to ten .. it is zero .. now in the earliest days there was no d10 die .. there was a d20 die .. numbered 0-9 twice .. i think all the confusion has only appeared since the introduction of the d10 double digit dice ., when you were just rolling 2 single difit dice .. made it clear a 7 and a 1 was 71 .. the two shown digits were your two decimal places .. with only 00 needing any interpretation as 100 instead of zero

[wbaileyjr]

00 + 1-9 = a single number. 00+0=100. It's actually simple.

[CarnageV]

I noticed that there are 2 versions of the d100/percentile dice as the numbering layout is different. Is this a problem for games?

[heyjade]

So.. the legacy version is
00+0 =100
00+1 = 1
00+2 = 2
& So on, then
10+0 = 10
10+1 = 11
20+0 = 20
30+0 = 30
& so on
and 90+0 = 90
90+9 = 99
Right?

I’m new to dnd so if this is the case that’s seems simple enough! You just wouldn’t have a chance at rolling zero which I think maybe better for the majority of players .. if you roll a 1 that’s better than a 0 but it’s basically getting you the same results .. right?

[cameronowens]

So...wait...does that mean if you roll a 00 on the 10s dice and a 5 on the d10, does that make it a total roll of 5???

[Gothaprick]

Thank you for this content. I didn't know how it was done until I saw this video.

[walterstarr]

The adding version ignores the entire history of chits and polyhedral dice in TTRPGs, thus it can be ignored as irrelevant. Originally, there were chit bags. The d10 bag had 0-9 and 0 was ten when pulling for just a number between 1 and 10. When pulling for percentile, the first one was tens and the second pull was single digits. so pulling a 0 on the first pull and a 0 on the second pull was how you got 100. It has worked that way since White Box Days. I know as I started DMing the white box during the mid 70s. We didn't have polyhedral dice to begin with and when we got them, there were no d10s. We had d20s numbered 0-9 twice. We colored in half the die with a black crayon for 11-20 (black 0 was 20) and a white crayon for 1-10 (white 0 = 10). We would ignore crayon colors and roll percentiles with two of these d20s until we finally got d10s. 0 and 0 was ALWAYS 100.

Super interesting and helpful. As a newbie dm I'm looking forward to future videos. Thank you.

[EmilyLynn]

That was awesome! You should totally make more videos! 💜

I roll 2d10s. The die that lands on the left represents the 10s digit. the one that lands on the right represents the single digit. If they land above and below eachother, top is 10s, bottom is 1s.

Now for examples:

10s lands a 10 and 1s lands a 5. Thats 15.
10s lands a 0 and 1s lands a 9. Thats 9.
10s lands a 0 and 1s lands a 0. Thats 100, because its impossible to land a 0 on a die.

So, all dice combinations from 2d10 range from 01 to 00, where 00 is 100.

When you're talking about the middle numbers both are basically equivalent, but at the extremes the adding method makes no sense. For the legacy version all zeroes is 100, but with the adding version that's actually 10. To get 100 using the adding method you have to roll a 90 and a 0, which just isn't as exciting.
