Roll polyhedral dice in your browser
This dice roller is built for tabletop RPGs, board games, and quick probability demos. Pick a die type — d4, d6, d8, d10, d12, d20, or d100 — choose how many dice to roll (up to ten), then press Roll. You will see every die face, the combined total, a short summary of your previous roll, and a history of the last five rolls. Use Space or Enter to roll again when you are not typing in another control.
Understanding die notation
In hobby games you will see phrases like 2d6 (two six-sided dice) or 1d20 (one twenty-sided die). This tool lets you pick the die size and the count so you can match common patterns: damage rolls, hit dice, d20 tests, and percentile-style 1–100 results on a d100.
Fairness and limits
Rolls are generated with your browser's pseudo-random APIs. That is standard for games and perfectly fine for casual and home play. It is not a certified randomness source for casinos, audits, or cryptography. You can roll at most ten dice per click to keep the layout readable on phones and desktops.
More ways to randomize
For a simple heads or tails, use the coin flip. For arbitrary integers in a range (not tied to physical die sizes), use the random number generator.
Frequently asked questions
What does d20 mean?
It means one twenty-sided die. The "d" is shorthand for die; the number is how many sides it has. d20s are central to many fantasy RPG rules for checks and attacks.
What is d100 used for?
d100 represents a uniform roll from 1 to 100, often called a percentile roll. It is used for tables where outcomes are spread across a full percentage range.
Can I roll more than one die at once?
Yes — choose between one and ten dice. Each die is rolled independently; the page shows each value and adds them for the total.
How is the total calculated?
The total is the arithmetic sum of all dice in the current roll. Your history entries include the list of values, the total, the die type, and how many dice you rolled.
Is this dice roller suitable for D&D?
Yes for typical online or in-person play when digital dice are allowed. Always follow your table's house rules about physical versus digital rolls.
Are rolls truly random?
They are pseudo-random and fine for games and education. Do not use this tool when you need cryptographic-grade or legally certified randomness.
How do keyboard shortcuts work?
Space or Enter triggers a new roll when focus is not inside an input-like control and not on a button, so you can keep one hand on the keyboard during play.
Is this dice roller free?
Yes — free to use with no signup or download.
