Dice Roller: Roll d4 to d100 Online, Free and Private

Roll d4 through d100 in your browser. Pick a die, set how many, add a modifier, and hit roll. Nothing is sent to a server.

Pick a die type, pick how many you want, and hit roll. Every die shows its own face, and the total appears underneath so you never have to add them up yourself. It handles d4 through d100, several dice at once, and a bonus or penalty on the total. Rolls happen in your browser.

How the roller works

Set the die type first. Then the count. Then roll.

The result splits into two parts: the individual faces, and the sum. That matters more than it sounds. If your group only cares about the total, read the big number. If someone rolled eight d6 for a fireball and wants to reroll the 1s and 2s, the faces are right there.

The modifier field adds to the total once, not once per die. So 2d6+3 gives you two dice and a single +3, which is what your character sheet means.

Every die you’re likely to need

All seven standard dice are built in.

The seven standard dice in a row: four-sided d4, six-sided d6, eight-sided d8, ten-sided d10, twelve-sided d12, twenty-sided d20, and the percentile d100 — The seven dice this roller supports, from d4 to d100.

Die	Faces	Average roll	Mostly used for
d4	4	2.5	Small damage rolls, spinning-top games
d6	6	3.5	Board games, Yahtzee, most damage dice
d8	8	4.5	Weapon damage in tabletop RPGs
d10	10	5.5	Damage rolls, percentile pairs
d12	12	6.5	Heavy weapon damage
d20	20	10.5	Attack rolls, skill checks
d100	100	50.5	Percentile tables, loot rolls

A natural 20 turns up 5% of the time. Two d6 land on seven more often than any other total, at 16.67%.

If you want to know why some totals show up more than others, the dice probability page walks through it. The full list of die types covers what each one is normally used for.

Roll history and shortcuts

Recent rolls stay on screen, so you can look back at the last few without writing anything down. Press the spacebar to roll again, which is faster than reaching for the mouse forty times in one combat.

It works on a phone the same way it works on a laptop. No app to install.

Rolls happen in your browser

Nothing is sent to a server. Your browser’s built-in random number generator produces the numbers on your own device, and the result never leaves it. There’s no account, no signup, and no log of what you rolled sitting somewhere else.

For tabletop play, the D&D dice roller handles advantage and full sets. If you’d rather type 4d6d1 than click, dice notation explains the format.

FAQ

Is this dice roller actually random?

The numbers come from your browser’s built-in random number generator, which is designed to produce values with no predictable pattern. It’s not a physical die, so it can’t be weighted or shaved. For a home game or a tabletop session, it behaves the way a fair die does.

Can I roll more than one die at a time?

Yes. Set the count and every die rolls together, with each face shown separately and the total added up for you. That covers six d6 for a Yahtzee turn or eight d6 for a spell. There’s no practical reason to roll them one at a time.

Do I need an account to use it?

No. There’s no signup, no login, and nothing to install. Open the page and roll. Because the rolls run on your device rather than on a server, there’s no account for the site to attach them to in the first place.

Does it work offline or on a phone?

The layout adapts to a phone screen, and the buttons are sized for thumbs. Once the page has loaded, the rolling itself needs no connection, since the whole thing runs locally. Refreshing the page after you’ve gone offline may not work.
