Online Dice Roller

DiceRoll lets you roll one to four six-sided dice directly in your browser. Choose how many you need, press Roll Dice, and watch them tumble, collide, and settle inside the virtual tray. The upward-facing side of each physical die determines its value; DiceRoll reads those values and calculates the total.

Quick Guide

How to Roll Dice

01

1. Choose your dice

Select between one and four standard six-sided dice using the selector bar.

3. Let them settle

The dice bounce, rotate, and collide until they naturally come to rest.

4. Read your result

The upward-facing side of each die determines its value and the total.

How a Six-Sided Die Works

A standard six-sided die, or D6, has faces marked from 1 to 6. On a standard die, opposite faces add up to seven.

Opposite faces on a standard six-sided die add up to seven.

1↔61 + 6 = 7
2↔52 + 5 = 7
3↔43 + 4 = 7

Dice Probability

For an ideal fair D6, each face has a 1 in 6 chance. With two ideal dice, totals range from 2 to 12. The total 7 has the most combinations: 6 out of 36.

Questions & Answers

Frequently Asked Questions

Are the dice results random?

Each roll starts with new randomized physical conditions. The result comes from the upward-facing side after each die has stopped. Like physical dice, the simulation can produce repeated values.

How is the dice result determined?

After the dice settle, DiceRoll reads each die’s physical rotation, identifies its upward-facing side, and adds those values together.

Can I roll more than one die?

Yes. You can roll one, two, three, or four six-sided dice together.

Can I use DiceRoll on my phone?

Yes. The tray and controls adapt to desktop, tablet, and mobile screens.

What does D6 mean?

D6 means a six-sided die with faces numbered one through six.

Do opposite sides of a die add up to seven?

Yes. On a standard D6, opposite faces are 1 and 6, 2 and 5, and 3 and 4.
