About DnD Dice Roller

DnD Dice Roller – Roll D4 to D100 with Modifiers

Roll tabletop RPG dice online in a fast, transparent way. This DnD Dice Roller supports common dice from D4 through D100, lets you roll multiple dice at once, and applies a modifier so you can resolve checks, attacks, and damage in one click. It is ideal for quick rolls during play, prep, or solo testing.

How the DnD Dice Roller Works

This tool simulates physical dice by generating a random result for each die you choose, then adding them together and applying your modifier. You can optionally display every individual die so the roll is easy to verify, just like watching dice tumble across a table.

Because dice rolls are the heartbeat of many RPG systems, the output is written in a human-friendly format. You will see the classic notation (like 3d8 + 2) alongside the computed numbers, making it easy to cross-check against a printed character sheet. If you are teaching new players, the notation and breakdown also help explain why a final number is what it is.

Step-by-Step

  • Choose your die: Pick the number of sides (D4, D6, D8, D10, D12, D20, or D100) based on the roll you need.
  • Set the quantity: Roll one die for a single check or multiple dice for damage, healing, or custom tables.
  • Add a modifier: Enter a positive or negative modifier (for proficiency, ability score, magic bonuses, penalties, or situational effects).
  • Optionally show details: Turn on the detailed view to list each die result, useful for damage rolls or when you want full transparency.
  • Generate the result: The output includes the dice notation, individual rolls (if enabled), subtotal, modifier, and the final total.

Key Features

Supports the Dice You Use Most

DnD and many other tabletop systems revolve around a small set of standard polyhedral dice. This roller includes D4, D6, D8, D10, D12, and D20 for the core mechanics, plus D100 for percentile rolls and random tables.

Roll Multiple Dice in One Click

Whether you are rolling 2d6 for a spell effect, 8d6 for a fireball, or a handful of dice for monster damage, you can specify the number of dice and get a clean summary instantly. The tool calculates the subtotal for you so you can focus on the story instead of arithmetic.

For larger rolls, the result stays readable. The tool summarizes totals first and then, if you choose details, lists the dice in a compact comma-separated line. That way you can roll many dice without losing track of what happened, and you can still quickly announce the final number to the table.

Modifiers Made Simple

Most DnD rolls are “dice plus modifier.” The modifier field lets you enter any bonus or penalty, so you can resolve ability checks, saving throws, attack rolls, or damage with the same workflow. The output clearly shows the modifier and final total.

Transparent Breakdown

When you enable the detailed breakdown, the tool lists every individual die result. This is helpful for trust at the table, for streaming sessions, or for confirming that damage dice were rolled correctly. You still get a final total, but you also get the full trail.

Copy and Download Results

Need to share a roll in chat or paste it into session notes? Use the Copy button to put the result on your clipboard. You can also download the output as a text file, which is handy for logging combats, tracking loot tables, or keeping evidence of a series of rolls.

Use Cases

  • Ability checks: Roll 1d20 and add your skill modifier to resolve stealth, persuasion, investigation, and more.
  • Saving throws: Roll a D20 with the correct bonus to resist spells, traps, breath weapons, or environmental hazards.
  • Attack rolls: Roll 1d20 plus proficiency and ability modifiers to see if you hit a target’s Armor Class.
  • Damage rolls: Roll multiple dice (for example, 2d6 or 1d8) and add a modifier for weapons, spells, sneak attack, or class features.
  • Percentile tables: Roll D100 to resolve random encounters, critical injury charts, treasure tables, or homebrew generators.
  • Quick NPC outcomes: Roll a die to decide behavior, attitude shifts, or improvisational story beats without slowing down play.
  • Remote sessions: Use a shared roller during online games so everyone can see the notation and the final number.

Because the tool is flexible, you can use it beyond DnD. Many systems use the same dice set, and even when rules differ, you can still roll the underlying dice and apply the right modifier or interpretation. For example, you can roll a D20 for a generic success check in a homebrew system, roll multiple dice for narrative “degrees of success,” or use D100 to pick outcomes from a custom probability table.

If you run a game as a dungeon master, quick rolls can also help you improvise. Need to decide which corridor the monster patrol is taking, how loud an explosion is, or whether a suspicious NPC is telling the truth? A fast, labeled roll keeps the pace up and prevents you from getting stuck on indecision. Players benefit too: they can resolve routine checks without searching for physical dice or waiting for a turn cycle to finish.

Optimization Tips

Use Clear Notation in Notes

When you label a roll (for example, “Stealth check in darkness” or “Fireball damage vs. clustered goblins”), it becomes easier to review results later, especially during long sessions or when you are keeping a combat log. Clear notes also help DMs verify context quickly.

Turn on Details for Damage, Off for Speed

For single D20 checks, you often only care about the final number. For multi-die damage, the breakdown is useful for transparency and for rules that trigger on specific die results. Consider toggling details on when you need a per-die view, and off when you want the cleanest output.

Use D100 for Fast Randomization

If you rely on random tables, percentile rolls can speed up improvisation. Keep a list of your favorite tables nearby and use D100 rolls to choose outcomes quickly. The tool’s output format makes it easy to copy a result into notes or a virtual tabletop chat. You can also chain percentile results with additional dice—for instance, rolling D100 to select an encounter type and then rolling 2d6 to determine the number of creatures involved.

FAQ

Yes. It supports the standard dice used by DnD (D4, D6, D8, D10, D12, D20) and includes D100 for percentile tables. You can also apply modifiers to match ability scores, proficiency, and situational bonuses.

The modifier is added to (or subtracted from) the dice subtotal. This mirrors typical tabletop rules where a roll is “dice + bonus,” such as 1d20 + Strength modifier or 2d6 + spellcasting bonus.

Yes. Enable the “Show individual dice” option to list every die result in the output. This is particularly useful for damage rolls, healing, or any situation where transparency matters.

You can roll multiple dice in a single request. For performance and readability, the tool sets reasonable limits, but it is more than enough for common tabletop scenarios like spell damage or large creature attacks.

The tool uses a cryptographically secure random number generator provided by the server runtime to produce each die result. While no digital system can “feel” like physical dice, the distribution is suitable for gameplay and consistent across sessions.

Why Choose This Tool?

This DnD Dice Roller is designed for speed, clarity, and trust. The interface keeps settings on the left and results on the right, with a clean empty state before you roll. The output shows both notation and totals so you can communicate results in chat, add them to notes, or verify multi-die damage at a glance. When you enable individual dice, you also get a transparent breakdown that mirrors the experience of reading physical dice on the table.

Whether you are playing in person, running a remote session, or preparing encounters and tables, a reliable dice roller reduces friction. Pick your die, set quantity and modifiers, and roll—then copy or download the result to keep your session moving smoothly. The notes field is optional, but it is useful for labeling repeated rolls during combat (such as “Round 3: Smite damage”) or for tracking test probabilities when you are balancing a homebrew feature.
