1) input a die code
2) press enter to roll
3) rinse, repeat!
Name generator beta: type "name gen [template]", where template is one
or more of our naming templates (default, byname, fantasy, rome, wh) to generate a bunch of random names
for your NPCs.
They keep resetting the Facebook like counter every few months, not sure why. So we're back to zero, again.
Double-click a die to roll it! ^
Welcome to the Roleplayer's Online Dice Roller, your one-stop virtual bag of dice! The Roller interprets
standard dice codes presented in the standard notation.
Click once to load it into the textbox on the left.
In order to get a result, please enter the dice code into the input field and hit enter.
You can also click on the standard dice on the right to load them into the field. Click double
if you want to roll one of them right away. It's an AJAX application, magical things will happen!
Examples: (click once to load, click twice to roll right away)
▶ Basic Dice Codes
▶ Success-Based Rolls
- Count the number of successes: to see how many dice rolled equal to or greater than some number, use "E".
The default die of this roll type is d6, so 4e4 can be used as a shorthand for 4d6e4.
- Successes with additive re-roll: to see how many dice rolled equal to or greater than some number,
use "R" if you want the individual die maximum to trigger a re-roll. This way, you can have target difficulties greater than the max number of the die.
The system also gives you the number of ones rolled (if there were any) so you can judge whether an action resulted in a fumble.
The default die of this roll type is d6, so 4r8 can be used as a shorthand for 4d6r8.
- Successes minus failures: to see how many dice rolled equal to or greater than some number, and subtract the amount of ones rolled, use "F".
The default die of this roll type is d6, so 4f4 can be used as a shorthand for 4d6f4.
- Successes "plus": to see how many dice rolled equal to or greater than some number, and roll every max result again and see if it's another success, use "M".
The default die of this roll type is d10, so 4m4 can be used as a shorthand for 4d10m4.
- Successes with everything: to see how many dice rolled equal to or greater than some number, and roll every max result again, and subtract the amount of ones rolled, use "S".
This is probably the one you want for most systems.
The default die of this roll type is d10, so 4s4 can be used as a shorthand for 4d10s4.
- Successes with multiple dice:
Some systems use the cumulative result of two or more dice to determine successes, here the sum of several dice
is compared to the difficulty rating. To emulate this, you can group dice like this:
1D6:6S4 , meaning 2d6 will be rolled and 4(+) is a success.
5D6:8S10 , here a d8 and a d6 will be rolled, a sum of 10(+) is a success, the entire check is rolled 5 times.
- Maximum possible die result counts as two successes: to see how many dice rolled equal to or greater than some number, use "X".
The default die of this roll type is d6, so 4x4 can be used as a shorthand for 4d6x4.
- Get the highest roll:
To see only the highest roll, just leave the success/difficulty rating out.
- Generate random names:
name gen [template], where [template] is the style of name
you want to create. Supported templates are
default (just generic names),
rome (pseudo-latin), and
wh (Warhammer FRPG names).
You can also chain several templates together by separating them with a space in between.
name gen wh
▶ Power User Stuff
- To see how an individual result came to be, let the mouse pointer hover above the number to see more details. If your
browser won't show the details, click on the result to expand it instead.
- Multiple rolls at once: to roll for multiple things (e.g. an attack and a damage roll), you can
chain together dice codes by semicolons.
- A number of rolls: if you want to repeat the same roll for a number of times,
repeat command. If you also want the sum of the rolls, use
sum instead of
repeat 6 3D6 or:
sum 6 3D6+3
- You can add comments to your roll by appending a pound sign # followed by some text to your code, like this:
1D20+2 #attack roll
Custom attributes: another way to define custom rules for a single roll command is using attributes. The following attributes are currently supported:
You can combine attributes with another, and also use macros (see below) to invoke them. It doesn't matter
if an attribute comes before or after the actual dice code, as long as they are separated by a space.
- reroll: ignore one or more results and roll again ( reroll=1,2 4d6 )
- round: round up all results below this number ( round=3 d10 )
- explode: specify one or more results that cause the die to be rolled again and the result added up ( explode=5,6 4d6 )
- default die: specify another default die ( die=4 7z4 )
- count: count the occurrences of specific die results ( count=1,2 10d6 )
Defining criticals: you can specify what your critical rules are with the rule crit command.
You can define macros to automate repetitive die rolls or often-used number constants (such as your attack bonus).
- Saving and loading user data: you can save your customizations (such as the macros you defined)
for later. To save your current session, type "save MyCoolUserName" where MyCoolUserName is an
arbitrary name for your session. You have to remember this name in order to retrieve the session
later with the corresponding command "load MyCoolUserName".
