Dice Roller
Roll one die or a whole handful — fair results with the total added for you.
This dice roller throws virtual dice with fair, random results. Roll a single six-sided die or several at once, and the total is added up for you. Beyond the classic D6, you can roll the polyhedral dice used in tabletop games: D4, D8, D10, D12 and the famous D20.
It steps in whenever the real dice have gone missing: board game night with a lost die, Monopoly or Yahtzee on holiday, classroom probability lessons, or a quick Dungeons & Dragons session where someone forgot their dice bag. Because each roll is an independent random draw, every face has an equal chance on every throw.
Rolls happen instantly in your browser on your device, with no app to install and no account.
How to roll dice online
- Choose the type of die: D6 for board games, D20 and friends for tabletop RPGs.
- Set how many dice to roll at once, for example 2 for Monopoly.
- Click roll and watch the dice land.
- Read each die's result and the total, summed automatically.
- Roll again as often as the game demands.
What the dice roller does
The dice roller gives you a full set of fair dice on demand, so a missing die never stalls a game. Pick the type of die, choose how many to throw, and it rolls them all at once and adds up the total for you. It covers the everyday D6 for board games and the polyhedral set, D4, D8, D10, D12 and D20, that tabletop role-playing games rely on.
Adding up the total automatically is more useful than it sounds: it removes the arithmetic slips that creep in during a fast game and speeds up turns where you roll several dice at once. Whether you need one die for a board game or a handful for an RPG attack, the result and the sum appear together in a single click.
How the roll works in your browser
Each die is rolled using your browser's built-in random function, which picks one face with equal probability, and the animation then shows the dice settling on those values. The numbers are decided the moment you click; the tumbling you see is just the reveal. Rolling several dice simply repeats that independent draw once per die and totals the results.
It all runs locally on your device, so there is no server involved and nothing to install. That is why rolls are instant, why the tool keeps working offline once the page has loaded, and why no one, including us, can nudge a roll toward a particular number.
Two dice are not like one: totals and odds
A single D6 gives each number a flat 1-in-6 chance. Roll two and the totals stop being equal: 7 is the most likely sum (6 ways to make it), while 2 and 12 come up only one way each. That is why settlements on 6 and 8 in Catan pay off so often and why snake eyes feels rare; it genuinely is.
For RPG players: rolling here is handy for a forgotten dice bag or a quick online session, though at many tables the group's habit of rolling in the open matters more than the tool. Agree with your table before swapping physical dice for digital ones mid-campaign.
Are the rolls fair, or can they be rigged?
The rolls are fair. Every face has an equal chance on every throw, and the tool does not know or care whether you are hoping for a natural 20 or dreading a 1. There is no hidden weighting, no house edge, and no way for the result to be set in advance, because it is drawn on your own device the instant you click.
Fairness across many faces looks different from a coin's even split, so do not mistake normal variance for bias. Over a short session you might see three 20s and no 1s, or the reverse; both are ordinary luck. Roll a die a few hundred times and the counts even out toward one-in-six (or one-in-twenty), which is exactly what fair dice should do.
Every roll is independent
The dice have no memory. A number that has not appeared in a while is not "due", and a face that just came up is no less likely next time; each roll starts fresh with the same odds. This is the gambler's fallacy in dice form, and it trips up even experienced players who feel a bad run must be about to turn.
This is worth keeping in mind for both games and lessons. A streak of low rolls in an RPG is frustrating but not a malfunction, and the tool will not correct it to be kind. In a probability lesson, that same behavior is the point: independent rolls are unpredictable in the short run yet settle into the theoretical odds over many trials.
Where a virtual dice roller helps
The obvious rescue is a missing or lost die: board game night, Monopoly or Yahtzee away from home, or a Dungeons & Dragons session where someone left their dice bag behind. Set the die type and count and play carries on at normal speed, with the total added for you so no one has to do the mental maths mid-turn.
It is also a genuinely good teaching tool. Project it in a classroom, roll repeatedly, and tally the outcomes so students see randomness and probability play out live, including how two-dice totals cluster around 7. The same setup works for any activity that needs an impartial number, from picking a random amount to running a simple game of chance.
Related tools for chance
Dice are ideal for numbers and games, but sometimes a simpler chooser fits better. For a straight two-way decision, the Coin Flip is quicker than rolling and reading a die, and when you want to pick one option from a written list, the Spinner Wheel turns your choices into a visual spin.
If the thing you are choosing is a person, the Random Name Picker handles names as a plain list and can remove each pick so nobody repeats. All of these tools sit alongside the dice roller with the same principles: they run entirely in your browser, treat each result as independent with no memory of the last, and give every outcome a genuinely fair chance.
Frequently asked questions
Are the rolls actually random?
Yes. Each roll is an independent random draw where every face has an equal chance, with no memory of previous rolls and no streak correction.
Is the dice roller free?
Yes, free and unlimited with no sign-up. Roll all night if the game runs long.
Can I roll two dice for Monopoly or Catan?
Yes. Set the count to 2 and roll; both dice and their total are shown, so gameplay moves as fast as with real dice.
Does it have a D20 for D&D?
Yes. Choose the D20, or any of the standard polyhedral set (D4, D8, D10, D12), for ability checks, attacks and saves when your physical dice are elsewhere.
Why do some totals come up more than others with multiple dice?
Because more combinations produce middle totals. With two D6 there are six ways to roll a 7 but only one way to roll a 12, so mid-range sums appear far more often. That is correct probability, not bias.
Can the same number come up several times in a row?
Yes, and it is normal. Each roll is independent with no memory of the last, so repeats and streaks happen by chance; no number is ever 'due'.
Can I use it for classroom probability lessons?
Yes, it is ideal. Roll repeatedly on the projector and tally the outcomes; with enough rolls, students watch the results converge toward the theoretical odds.
Does it work on phones and tablets?
Yes. It runs in any modern mobile browser, which is exactly what you need when the dice are missing mid-game.
