How to Use DnD Dice Roller

DnD Dice Roller is built to be quick for simple rolls and flexible enough for more advanced tabletop setups. You can use it for a basic 1d20 check, a reusable multi-line combat setup, a 5E ability score roller, or more specialized AD&D and custom-rule rolls.

This guide walks through the main controls, the advanced options, and a few practical examples.

Annotated overview of the main DnD Dice Roller controls

Figure 1. Overview of the main controls.

The basic layout

A single dice line has five main parts:

  1. Line label
    This is the text shown at the top of the line. You can leave it as the automatic label or replace it with something more useful such as Strength, Attack Roll, or Short sword damage.

  2. Main roll controls
    These are the standard controls used to build the roll:

    • number of dice
    • die type
    • plus or minus
    • modifier value
    • whether the modifier applies to each die or to total
  3. Result box
    This is the blank box to the right of the line. When you roll, the result appears here.

  4. Roll button
    This rolls the current line only.

  5. Line actions
    The buttons at the left let you expand the line, remove it, or duplicate it.

You can also use the controls above the list to expand all lines, save your setup locally in the browser, and toggle sound.

Saving your setup and toggling sound

At the top of the roller are two optional toggles:

  • Save setup locally
    This stores your current configuration in your browser so you can return to it later.

  • Toggle sound
    This enables or disables the roll sound effect.

Saved settings are local to your browser and device. If you clear local browser data or use private browsing, your saved setup may not persist.

Adding a custom label

The label field is useful when you want each line to represent a real gameplay action rather than just a dice formula.

For example, instead of leaving a line named 1d6, you might rename it to:

  • Short sword damage
  • Initiative
  • Saving Throw
  • Strength
  • Fireball Damage

Understanding the main roll controls

The main controls define the actual dice expression.

For example, a line set to:

  • 4
  • d6
  • +
  • 0
  • to total

means the line will roll 4d6 and apply no modifier.

A line set to:

  • 1
  • d10
  • +
  • 5
  • to total

means the line will roll 1d10 + 5.

If you switch the final setting from to total to to each, the modifier is applied to every die individually instead of being added once at the end.

Expanding a line and using advanced options

When you expand a line, you unlock the advanced controls.

Line actions

When a line is expanded, the buttons on the left become especially useful:

  • triangle button: collapse or expand the line
  • minus button: remove the line
  • ++ button: duplicate the line
  • plus button below the list: add a brand new line

Advanced option 1: Drop or reroll

The first advanced option lets you choose:

  • Drop or Reroll
  • lowest or highest
  • how many dice

This is one of the most useful additions to the tool because it supports several common game mechanics.

Examples:

  • 5E advantage: roll 2d20 and drop lowest 1 dice
  • 5E disadvantage: roll 2d20 and drop highest 1 dice
  • 5E ability scores: roll 4d6 and drop lowest 1 dice
  • custom or homebrew rules that reroll extreme values

Advanced option 2: Minimum or Maximum per die

The second advanced option lets you apply a Minimum or Maximum value per die.

This gives you a way to create rolls that are hard to reproduce with physical dice, especially for:

  • AD&D-style or older-school variants
  • custom class features
  • homebrew rules
  • experimental encounter or loot systems

For example, a minimum result per die can enforce a floor on each rolled die before the total is calculated.

Building a multi-line setup

DnD Dice Roller becomes much more powerful when you use several lines together.

Multi-line ability score roller setup

A multi-line setup is useful when you want to:

  • roll a full set of ability scores
  • quickly roll damage for high level spells
  • build repeated attacks for a monster or NPC
  • prepare different damage types on separate lines

Each line can have its own label, but the same roll structure can be reused across multiple lines. The ++ button is especially handy here because it lets you duplicate the current line instead of rebuilding it from scratch.

Example 1: Rolling with advantage in D&D 5E

A standard 5E advantage roll is easy to set up.

Annotated advantage roll example

Figure 5. Example setup for rolling with advantage.

To do it:

  1. Set the roll to 2d20
  2. Expand the line
  3. Enable the first advanced option
  4. Set it to Drop lowest 1 dice
  5. Roll the line

That keeps the higher of the two d20 results.

For disadvantage, use the same setup but switch the option to Drop highest 1 dice.

Example 2: Minimum result per die

The second advanced option is useful when you want each die to obey a floor or ceiling.

Annotated minimum-per-die example

Figure 6. Example setup using a minimum per die.

In the example shown above, the line is configured as:

  • 1d10 + 5 to total
  • Minimum of 2 per die

This kind of setup can be useful for AD&D-inspired rules, special class features, or custom systems where extremely low single-die results should be constrained.

Example 3: 5E ability score roller

One of the most common 5E character creation methods is:

4d6, drop the lowest die

A clean way to build that setup is:

  1. Create one line
  2. Set it to 4d6
  3. Enable the first advanced option
  4. Set it to Drop lowest 1 dice
  5. Duplicate the line until you have six total lines
  6. Rename the labels to:
    • Strength
    • Dexterity
    • Constitution
    • Intelligence
    • Wisdom
    • Charisma
  7. Use ALL to roll the full set

The multi-line screenshot above shows exactly this kind of reusable stat roller.

Rolling all lines at once

When you have more than one line in the roller, the ALL button appears below the list. This rolls the whole set in one action.

This is ideal for:

  • rolling a full set of character stats
  • resolving multiple attacks quickly
  • running repeated encounter rolls
  • testing several related dice expressions in one click

Practical tips

A few habits make the roller much easier to use:

  • Use clear labels so you know what each line is for
  • Duplicate lines when you need variations of the same roll
  • Use ALL for grouped actions
  • Save locally when you build a setup you want to keep
  • Expand a line whenever you need access to the advanced options

Final thoughts

DnD Dice Roller works well as a simple online die roller, but it becomes much more useful once you take advantage of:

  • custom labels
  • multi-line setups
  • duplicate line workflow
  • drop or reroll rules
  • minimum and maximum per-die rules
  • roll-all functionality

That makes it suitable not only for casual rolls, but also for structured use in D&D 5E, AD&D-style play, and custom tabletop systems.
