Dice Roller

Roll dice with any number of sides. Set Sides from 2 to 100 and Rolls from 1 to 1000; the output panel fills with that many results, one integer per line, drawn uniformly from 1 to Sides inclusive. Useful for tabletop games (d20, d6, d4) and any picks-from-N decision. For pure 50/50 outcomes see coin flip.

Custom dice for any face count

A die with N sides produces an integer from 1 to N inclusive on each roll, with every value equally likely. The roller draws each integer via floor(random() * sides) + 1, which is the standard formula. Each roll is independent of the previous one, so the same number can come up several times in a row.

Sides ranges from 2 to 100, covering the standard tabletop set (d4, d6, d8, d10, d12, d20) and well beyond. Rolls ranges from 1 to 1000 for bulk runs.

For pure binary outcomes use the coin flip instead. For arbitrary integer ranges (negatives, zero-inclusive, capped at any max) use the random number generator.

What this tool actually does

Any face count from 2 to 100

Sides can be any integer from 2 (a coin-style die) up to 100 (a percentile die plus some). The standard tabletop set (4, 6, 8, 10, 12, 20) all work, as do unusual values like 7 or 13.

Inclusive range 1 to N

Each roll is an integer from 1 to Sides, both endpoints reachable, with equal probability for every value.

Bulk rolls up to 1000

Rolls ranges from 1 to 1000. Each roll is independent; expect repeats and short runs of the same value.

Plain integer output

Each line is one whole number, no decoration. Easy to sum, average, or paste into a spreadsheet.

Browser-only

Computed via Math.random(). No upload. Suitable for casual gaming and fixtures; not cryptographic.

Worked example

Ten rolls of a six-sided die (default settings). Expect short runs of the same value; over many rolls the average converges to (N+1)/2, here 3.5.

FAQ

Can I roll multiple dice at once and sum them?
Not in one click. Set Rolls to the dice count, copy the result, and sum it in a spreadsheet. Or run the random number generator with Min equal to dice count and Max equal to dice count times sides for a rough single-roll proxy.
Why does the same number keep coming up?
Each roll is independent. Short runs of the same number are normal; over hundreds of rolls every value will appear roughly 1/Sides of the time.
Can I use modifiers like d20+5?
Not directly. Roll the die at Sides 20, copy the result, and add the modifier in a spreadsheet or by hand.
Is this random good enough for tabletop?
For casual games, yes. Math.random() produces uniformly distributed values in [0, 1); the floor-and-add-1 step preserves that uniformity. For competitive play, use physical dice or a vetted RNG.
Is the output sent anywhere?
No. The rolls happen in your browser. Nothing leaves the page.
