Open the dice roller, pick your die type, choose how many to roll, and click Roll. Results land on screen immediately, complete with a total for multi-dice rolls.
Choosing the right die
The six buttons across the top correspond to the standard polyhedral dice you’d find in a tabletop role-playing game set:
d4 — a triangular pyramid. Used for small damage rolls or low-variance results.
d6 — the classic cube. The most familiar die in the world: board games, Yahtzee, Catan, Monopoly. The roller shows proper pip layouts (1 to 6 dots) rather than numerals, so it looks like the real thing.
d8 — an octahedron. Common in RPGs for weapon damage.
d10 — a ten-sided die. Often used in pairs (one for the tens digit, one for the units) to generate a number from 1 to 100.
d12 — a twelve-sided die. Found in some RPG systems and occasionally in board games.
d20 — the twenty-sided die. Central to Dungeons & Dragons and similar games; the higher the roll, the better the outcome.
For board games that use standard six-sided dice, stick with d6. For RPGs, you’ll likely switch between several types depending on what the rules call for.
Rolling multiple dice
Set the Dice counter to the number you need, up to 12. All dice roll at once, each result shown as its own tile. Below the tiles, the total appears — so “3d6” (three six-sided dice) gives you three individual values and their sum, the same information a physical roll would give you.
If you’re playing a game where you roll two d6 and count the total, that’s exactly what the two-dice d6 setting produces.
Why online dice are fair
Physical dice can be biased. A worn corner, an air bubble in the plastic, or a slightly lopsided mould all shift the probability away from perfectly even. A digital roller backed by cryptographic randomness has none of those flaws. Every face has exactly a 1-in-N chance of landing, where N is the number of sides. Over thousands of rolls, the distribution is as flat as a theoretical ideal.
This matters more than it might seem. In a long campaign, subtle bias in physical dice can meaningfully skew outcomes. Some players keep meticulous roll logs precisely to check their dice for this. An online roller removes the variable entirely.
Common uses
Tabletop RPGs. The most obvious case. When you’re playing remotely or just don’t have your dice bag to hand, the roller covers every standard type. Roll for initiative, attack, damage, or saving throws without interruption.
Board games. Any game that uses standard six-sided dice works here. Some players keep a phone handy as a backup when a die rolls off the table and gets lost under the sofa.
Decision-making. Assign options to numbers and roll. Let the result stand — it’s a commitment device as much as a random generator.
Teaching probability. Teachers and tutors use dice to demonstrate theoretical versus observed distributions. Roll a d6 a hundred times and chart the results; the bar chart should approach flat. An online roller makes this quick.
Game design. When prototyping a board game or RPG encounter, a fast online roller lets you test mechanics without setting up a full physical session. Need to know how often 3d6 exceeds 14? Roll it fifty times and see.
Reading the animation
The dice briefly animate on roll to give a tactile feel (on devices that support animation). If you prefer no motion — perhaps because of a vestibular condition or simply preference — your operating system’s “reduce motion” setting disables the bounce and the result appears instantly. The fairness of the result is identical either way.
