User Guide
- Choose how many dice to roll (1–6) and the die type — classic D6 or tabletop dice from D4 up to D100.
- Click “Roll the Dice” — classic dice show real pip faces; other dice show their number.
- Read the total and each individual die, plus running stats: highest total, average and recent rolls.
- Change the die type anytime — stats reset so averages stay meaningful.
About the Dice Roller
The dice are always the first thing missing from the box. This virtual dice roller replaces them instantly — up to six dice at once, from the classic six-sided die with real pip faces to the D4, D8, D10, D12, D20 and percentile D100 used in tabletop role-playing games. Rolls use cryptographically strong randomness, so every face is exactly as likely as physics would make it, and the running total, average and history are tracked for you.
Board game night, saved
Ludo, Snakes & Ladders, Monopoly, Yahtzee — one lost die stops all of them. Open this on a phone, set the right number of dice (two for Monopoly, five for Yahtzee), and play on. It works equally well for games over video calls, where one player rolls on a shared screen and nobody has to trust an off-camera “I got a six!” — the roll history keeps the last several results visible for the whole table.
D&D and tabletop RPGs without the dice bag
A full polyhedral set costs money and is never there when a one-shot session starts. The D20 covers ability checks, attacks and saves; the D4–D12 handle damage rolls; and the D100 does percentile tables. Roll multiple dice for damage (3 × D6 for a fireball) and read each die plus the total at a glance. New players can try the hobby with zero equipment.
A probability lesson students can see
Two six-sided dice make the best statistics demo there is. There are 36 possible combinations: only one makes 2 (1+1) and only one makes 12 (6+6), but six different combinations make 7 — so 7 turns up 16.7% of the time against 2.8% for the extremes. Set the roller to two dice, roll thirty times, and watch the average column settle toward 7 while 2s and 12s stay rare. That’s the bell curve, demonstrated with data the class generated themselves.
Random decisions with more than two options
Six chores, six people? Number them and roll. Twenty options? Use the D20. For exactly two outcomes the Coin Flip is quicker, and for choosing from a written list, the Random Picker takes names directly. Free, no sign-up, works on any phone, tablet or desktop.
Frequently Asked Questions
Which dice can I roll?
One to six dice at a time, choosing D4, D6, D8, D10, D12, D20 or D100 — covering board games, and tabletop RPGs like Dungeons & Dragons.
Are the rolls truly random?
Yes — rolls use the browser’s cryptographic random number generator, so every face is exactly equally likely.
Can I use it for D&D?
Absolutely. Pick a D20 for checks and saves, or roll multiple dice for damage. The history strip keeps recent rolls visible for the table.
Why is the average of two dice about 7?
With two six-sided dice there are more combinations that sum to 7 than any other total — the classic probability bell curve, which you can verify by rolling repeatedly.
Does it work on mobile?
Yes — the dice, totals and history all work with taps on any modern phone or tablet.
