How To Read D10, D100 and Percentile Dice Rolls

Deathstalker V explains using D10 dice and how to interpret their rolls. Stay tuned for more great Tabletop Hobby and RPG gaming coverage!

Always remember, we never roll 0, as there is no point. D100 is percentile. 00 + 0 is 100, any other numbers than 00 + any other number above 0, you add. If you get 00 and any number between 1 to 9, it is 0 + (1 to 9)

[VaughanCockell]

I would also add that historically, your second demonstration of d100 (two differently-coloured dice) predates the introduction of the 00-90 die. I would argue that the different colours approach shows how things are actually working better than the 00-90 die. The key things is generating an integer (single digit), then placing it in it's place in the result - tens and units as you said.

What seems to get people confused is the instinct to add the numbers together, instead of place them side by side.

I also think it's interesting to note that the reason a 0 on a d10 is read as 10 is the same reason a 00&0 is read as 100. The only positive number from 1-10 with a 0 in the units field is 10. Similarly, the only positive number from 1-100 with a 0 in the units field and a 0 in the tens field is 100.

Thank you so much for helping me not letting my table kill each other about a d100

[WickedScott]

Thank you! I just bought The Rogue Trader rpg series on Humble Bundle and am teaching myself the d10 system!!

[gremilyns]

Thanks so much for this, this is exactly what I was looking for, trying to rap my head around percentile dice

Why not a 90 and 10 is 100? Wouldn’t that make more since? And 00 means zero and you wouldn’t have to change what numbers mean in certain instances..

[MsHojat]

00-90 + 1-10 works just as well as 0-9 & 0-9. You just need to be clear which system is being used. Personally I don't like 0-9&0-9 because when you roll the first digit that should indicate ballpark of how good your roll was, but with 0-9&0-9 you won't know if you got a 1 or a 100 until rolling the second dice, which is silly.

[gabrielmajere]

The way I learned 0 is 10. So 70 + 7 is 77. But 70 + 0 would be 80. 00 + 8 would be 8. 00 + 0 would be 10 not 100. So how would you ever roll 100? Easy, 90 and 0.

[michaelhamilton]

Great content and well-explained. Thanks! This will help me as a keeper!

[LarisseMontrose]

Thank you kind sir lol I was having trouble and didn't want to ask anybody until/unless it came up.

[TokuRewinds]

So if I roll a 00 + What ever number (lets say 7), does that mean 107?

[MothiiCrochets]

Can you get a 1? Or any single digit number on a d100 roll with percentile dice?

[stevecrompton]

I like the short info pieces. That's great. I'm sure that's helpful for someone who hasn't messed around too much with 10 sided dice.

[randynunez]

Wouldn't a 10 (d100) + 0 (d10) = 20?

[VaughanCockell]

"The point is, you can never get a zero." Actually, that depends on the game system. Ars Magica, for example uses d10s exclusively, in most situations a 0 is read as 10, but in certain situations (stressful for example), the rules change, and the 0 is read as zero. Using d10s instead of the random number generator in the Lone Wolf solo gamebooks, has 00 mean zero. A result of 10 is never generated.

Just for your information.

[themorenajay]

I know this is ancient and this comment will probably drown... but is the case with ones & 100s the same if we have to roll two d100s? ( a drawing challenge wants me to roll two d100s and I'm not sure how to read them. I got a 20 & a 30 - so did I get a 23?)

[Frazijer]

Thanks for the video - the other scenario I wanted to check with the percentile dice is how to read 00 + any other single digit 1 to 9 (understanding that 0 would make that role 100). in the scenario of 00 + 7, that is a just 7 - correct? I'm certain this is how to read it, though i've yet to see this explicitly stated. Thanks

[destroso]

When you roll just one d10 the 0 is 10. When you roll the d10 and the d10-100 the d10 is read at face value, where the single digit 0 is now zero. If you roll 1-9 and 00, the 00 is now zero.

[lusolad]

So 00 and 06 is not 106? I dont understand.

[l.c.c.official.]

If theres no zero, and you’ve rolled a 70 on the percentile die, then proceed to roll a ten on the regular D10. Would that not be 80?
If not the entire idea of never rolling a zero is completely incorrect since the 0, or the 10 i should say does in fact turn to zero when you rounded down.
Am i trippin?
