Secure random numbers
Each die comes from the browser's cryptographic random source, not a predictable formula.
Free tool
Dice roller, fair every time.
Pick the dice and how many, add a bonus, and roll with a click or the space bar. Six-sided dice show their pips, the rest show their number, and the total is worked out for you. For tabletop games there is advantage and disadvantage, 4d6 drop the lowest, and a box for dice notation like 2d6+3 or 4d6kh3. Every face has exactly the same chance.
Or press the space bar.

Last rolls
The dice roll in your browser. The last rolls are kept in this browser only.
Fair dice
Every face, the same chance.
02 / No bias
Uneven leftovers thrown out
Random numbers that would make some faces slightly more likely are discarded and drawn again, so a d20 is exactly 1 in 20.
03 / Show
Decided before the shake
The tumbling is only for show: the result is fixed the moment you roll.
Questions
Good to know.
How do I write dice notation?
The number of dice, a d, then the sides: 3d6 rolls three six-sided dice. Add or take away a bonus with +2 or -1. kh3 keeps the highest three (4d6kh3), kl1 keeps the lowest. Write d20 adv or d20 dis for advantage and disadvantage.
What is advantage?
In Dungeons & Dragons and similar games, you roll two d20s and keep the higher one; with disadvantage you keep the lower. The dropped die is shown in grey.
What is 4d6 drop lowest?
A common way to roll a character's ability scores: roll four six-sided dice and add up the highest three.
Are online dice really random?
These are. Each result comes from crypto.getRandomValues, the browser's secure random source, and the method keeps every face exactly equally likely.
Can I roll a coin instead?
Yes, with flip a coin. For picking from a list of names, use spin the wheel.
