Online Dice Roller
Roll d4 to d20 dice online for free — up to ten at a time, totalled automatically.
Pick your dice and roll.
A dice roller that travels with you
Board games lose dice. Tabletop campaigns move online. Maths lessons need forty dice and the school has six. In all three cases a browser-based roller solves the problem in seconds, with no app to install and nothing to hand around a room.
For roleplaying games, the d20 handles attack rolls and saving throws while the multi-dice setting covers damage — set the count to eight, choose d6, and the total appears without mental arithmetic. For classroom probability work, rolling two d6 repeatedly and recording the totals builds the familiar bell-shaped distribution around seven, which is far more persuasive when the class generates the data themselves.
Need to pick a person rather than a number? The name picker wheel is built for that, and the team generator splits a group into balanced sides. For a plain numeric draw outside the standard dice sizes, use the random number generator.
Dice Roller FAQ
Which dice can I roll here?
The standard polyhedral set: d4, d6, d8, d10, d12 and d20. Pick a die, choose how many you want (up to ten), and every roll is generated independently, so 3d6 behaves exactly like rolling three separate six-sided dice.
Are these dice rolls actually random?
Each die uses crypto.getRandomValues() with rejection sampling, which removes the small bias you get from naive modulo arithmetic. Practically speaking, the odds match a fair physical die more closely than a real die does, since real dice are affected by manufacturing flaws and how they are thrown.
Can I use this for Dungeons & Dragons?
Yes, and the d20 is there for exactly that. Roll attacks and saves one die at a time, or set the count to roll damage dice together and read the total straight off the screen. The roll history keeps your last fifteen results so you can settle any dispute about what you rolled two turns ago.
Why use a digital dice roller instead of real dice?
Because dice get lost, roll off tables, and are hard to share in an online game. A digital roller also totals large handfuls instantly, which matters when a spell calls for 8d6 and nobody wants to do the arithmetic twice.
