Which dice can I roll?

You can roll d4, d6, d8, d10, d12, and d20, or choose Custom and enter any number of sides from 2 to 1,000.

Can I roll more than one die at once?

Yes. Set the quantity to roll from 1 to 12 dice of the same selected type, and the tool shows each result plus the combined total.

Are the virtual dice rolls random?

Yes. Every roll uses crypto.getRandomValues(), the browser’s cryptographically secure pseudo-random number generator. Its statistically uniform distribution gives each face of the selected die an equal chance of appearing.

Why does the total of two dice peak at 7?

A single die is uniform, but adding dice creates different numbers of possible combinations for each total. With 2d6, six combinations add to 7, while only one combination each produces 2 or 12, so 7 is the most likely total.

Do I need an app or account?

No. The Dice Roller runs in your browser without an app or login. It works client-side, sends no rolls to a server, uploads nothing, and can work offline after the page has loaded.

Dice Roller for Beginners: Make Your First Roll

A dice roller for beginners is a browser tool that lets you choose a die, choose how many dice to roll, and generate the individual results plus their total without installing an app. The Dice Roller supports d4, d6, d8, d10, d12, d20, and custom dice with 2 to 1,000 sides. You can roll from 1 to 12 dice of the selected type, so the same controls work for a first roll, a multi-die roll, or a nonstandard die. For a first-time user, the exact task is to match the die and quantity named by the activity, press Roll, and read the numbers that appear. After each roll, the tool shows every individual result, the combined total, recent roll history, and session statistics. Every roll uses the browser’s crypto.getRandomValues() CSPRNG rather than Math.random(), and the calculations run client-side. There is no app, login, or upload, and the page can work offline after it has loaded. This sequence suits board games, role-playing games, random decisions, and simple probability demonstrations.

Choose the die your activity calls for

The first decision is matching the dice notation used by the game, worksheet, or decision you are running. The letter d and the number describe the die’s faces: d6 is a six-sided die, while d20 has 20 possible values. A number before the d describes the quantity, so 2d6 means two six-sided dice. Dice Roller keeps those choices separate: first select the type, then set how many dice to use.

What you need	Dice selection	Beginner reminder
A role-playing attack roll or skill check	d20	This is the standard 20-sided die used for those checks.
Damage or another role-playing outcome	d4, d6, d8, d10, or d12	Select the exact type named by the game or activity.
A common board-game or card-game die	d6	The six-sided die is the familiar default for many tabletop games.
A nonstandard number of sides	Custom	Enter 2 to 1,000 sides, such as 100 for a d100 or 3 for a d3.

Use the exact die named in your instructions rather than choosing a nearby option by habit. If an activity calls for a d10, select d10 before adjusting the quantity. If it calls for a d100, choose Custom and enter 100. The custom value controls the number of sides on each die; the − and + stepper separately controls how many dice are rolled.

Make your first roll in three steps

Pick a dice type. Choose d4, d6, d8, d10, d12, or d20. To use another size, select Custom and enter any number of sides from 2 through 1,000. The selected type applies to every die in that roll.
Set the quantity and press Roll. Use the − and + stepper to choose from 1 to 12 dice of the same type. Check the requested notation before rolling: for 2d6, select d6 and set the quantity to 2. Then press the Roll button.
Read each result and the summary. Look at the individual outcome for every die first, then check the combined total. Use the short recent roll history and session statistics if you are making several rolls and want to review the session.

That is the complete basic workflow. You can change the die or quantity before starting another roll, while the history and statistics provide a record of the activity. There is no need to calculate the total yourself, and no separate code or browser command is required.

Read the outcome in the right order

The individual results show what each selected die produced. They are important when the dice can differ, such as a damage roll with multiple dice, because the combined total does not reveal which values contributed to it. Read these outcomes first and confirm that the die type and quantity match your intended roll.

The total is the combined result of the current group of dice. It is useful for activities that ask for one overall outcome, but it does not replace game modifiers or other rules that may apply outside the roller. For example, a role-playing check may still be interpreted according to the rules being used.

The recent history is intentionally short, while the session statistics summarize the ongoing activity. The available average-total figure is particularly useful when repeating the same type of multi-die roll. A single unusual total can affect that average, so the summary becomes more useful as more comparable results accumulate. History and statistics help you review completed rolls; they do not announce or guarantee a future outcome.

See why multiple dice are not repeated singles

One die has an equal chance of landing on each of its faces. When two or more dice are added, however, their totals do not all have the same probability. The possible sums form a bell-shaped distribution: middle results have more combinations, while the lowest and highest totals occupy the thinner ends.

With two six-sided dice, for example, 7 is the most likely combined total because more die combinations produce it. Totals of 2 and 12 are much rarer because each has only one possible combination. This is why repeatedly rolling 2d6 can demonstrate distributions and expected value more clearly than repeatedly rolling a single d6.

For a beginner, this distinction makes the history and statistics genuinely useful. Change only one setting at a time when comparing experiments. Keep the quantity and die type fixed to study a repeated multi-die pattern, or change the custom side count to explore how the range affects the outcomes. The tool handles the rolls; your notes or observations provide the interpretation.

Know how fairness and privacy work

The Dice Roller generates results with crypto.getRandomValues(), the browser’s cryptographically secure pseudo-random number generator, or CSPRNG. This randomness source is designed to produce a statistically uniform distribution, so each face of the selected die is equally likely. The results are not weighted toward high numbers, low numbers, or any particular face.

That differs from relying on Math.random(), which is fast but is not guaranteed to be uniform or unpredictable across browser engines. The Dice Roller’s disclosed implementation uses the CSPRNG directly for each roll. This describes the random-number mechanism; it does not remove the natural variation that remains when one die or several dice are rolled repeatedly.

Processing also stays in the browser. Rolls are never sent to a server, and nothing from the activity is uploaded. No application or account is required, which also means the tool can continue working offline once the page has loaded. These details make the roller suitable for tabletop play, quick decisions, and classroom demonstrations without adding an installation or account step.

Build a simple rolling routine

Identify the notation first. Decide whether the activity requires one die, several dice, or a custom side count before opening the controls.
Match the die exactly. A request for d8 means an eight-sided die, not eight dice. Quantity is a separate setting.
Check the group size. The tool supports up to 12 dice of one selected type, which is enough to reproduce common multi-die notation without changing tools.
Inspect results before totals. Individual values show how the total was formed and help catch a mistaken die type or quantity.
Compare like with like. When using history or average-total statistics for a probability exercise, keep the die and quantity consistent across the rolls being compared.
Define random decisions in advance. For a game or group choice, decide what each result will mean before pressing Roll so the outcome is applied consistently.

You do not need to memorize every dice type before starting. The main beginner habit is to read the requested notation carefully, select the die, set the quantity, and then verify that both choices match. Custom dice extend that same process to unusual ranges without introducing a separate tool.

A beginner’s first-roll checklist

Open the Dice Roller, choose the required die, set between 1 and 12 dice, and press Roll. Read the individual values, check the combined total, and review the history or statistics only when you need a broader view of the session. For standard games, start with the die named in the rules; for a nonstandard requirement, use Custom within the supported 2-to-1,000-side range. This process is enough to begin rolling while keeping the die type, quantity, and result easy to verify.
