What Is Online Dice Roller?
A dice roller simulates rolling physical dice — from standard six-sided dice to the polyhedral dice used in tabletop RPGs (d4, d6, d8, d10, d12, d20). It can roll multiple dice simultaneously, add modifiers and keep track of totals. Digital dice rolling is essential for online tabletop gaming and useful whenever physical dice are not available.
For tabletop role-playing games like Dungeons & Dragons, dice rolling is the core mechanic. A d20 determines whether attacks hit, skills succeed and saves are made. A combination of dice (like 2d6+3) determines damage and other effects. This tool handles any dice expression and provides a clear breakdown of each die's result.
How to Use This Tool
Select the type of dice to roll (d4, d6, d8, d10, d12, d20 or d100).
Choose how many dice to roll.
Optionally add a modifier (e.g. +3 for a D&D ability bonus).
Click "Roll" to see individual die results and the total.
View the roll history to track previous results.
Tips & Best Practices
Standard D&D notation: "2d6+3" means roll two six-sided dice and add 3 to the total.
For advantage/disadvantage in D&D, roll 2d20 and take the higher/lower result.
The average roll for any die is (max + 1) / 2 — so a d20 averages 10.5.
Digital dice are truly random, unlike physical dice which can develop biases from manufacturing imperfections.
Common Use Cases
Rolling dice for tabletop RPGs (D&D, Pathfinder, etc.) when playing online or without physical dice.
Quick dice rolls for board games when dice are lost or unavailable.
Generating random numbers within a specific range.
