How to Roll Dice Online Step by Step

Choose the type of dice. Select the dice you need, a standard six sided die, or the multi sided dice used in tabletop and role playing games, such as those with four, eight, ten, twelve or twenty sides.
Set how many to roll. Choose the number of dice to roll at once, so you can roll a single die or a handful together, as many games require.
Roll the dice. Press roll and the tool generates a fair random result for each die, with every face equally likely, just like fair physical dice.
Read the results and total. The individual results appear, along with their total, so you have both the separate rolls and the combined sum that games often need.
Roll again as needed. Each roll is independent, so roll again for your next turn or action, with fresh fair random results every time.

What Dice Are and How Fair Rolling Works

Dice have been used for games and decision making for thousands of years, providing a simple source of fair randomness. A standard die is a cube with six faces numbered one to six, and rolling it gives an equal chance of each number. This fairness is why dice are central to countless board games and games of chance: they introduce unpredictability that no player can control, making the outcome a matter of luck within the rules.

A fair die gives each face an equal probability, and a virtual dice roller achieves this with a random number generator that picks each result with equal likelihood. Done correctly, this is exactly as fair as a well made physical die, and free from the imperfections real dice can have from manufacturing or wear. Each roll is also independent, so previous rolls do not influence the next, the same fifty fifty style independence that governs all fair random events.

Each roll is fair and independent. A virtual dice roller gives every face an equal chance, as fair as a well made physical die and free from manufacturing imperfections. Each roll is independent, so previous rolls do not affect the next. Believing a number is due after a run is the gambler's fallacy.

Beyond the standard six sided die, role playing games use a whole family of multi sided dice, with four, eight, ten, twelve and twenty sides being common, plus others. Different dice suit different needs: a twenty sided die gives a wide range of outcomes for actions, while smaller dice suit damage or minor effects. A virtual roller can produce any of these instantly, which is especially convenient for games that use several different dice types.

Rolling multiple dice and summing them changes the probabilities in an interesting way. A single die gives each outcome equal chance, but the total of several dice is more likely to land near the middle of the possible range than at the extremes, because there are more combinations that produce a middling sum. This is why games using multiple dice have a characteristic feel, and a roller that shows both individual results and the total supports this naturally.

Pro Tips for Rolling Dice

Choose the right dice for your game. Different games use different dice. Select the type and number your game requires, whether a single six sided die for a board game or several multi sided dice for a role playing session.

Roll multiple dice together for totals. When a game needs the sum of several dice, roll them together so the tool gives both the individual results and the total, matching how the game uses them.

Remember the gambler's fallacy. A number is not due after not appearing for a while; each roll is independent with equal chances. Do not expect past rolls to influence the next, since fair dice have no memory.

Understand multiple dice cluster near the middle. The total of several dice tends toward the middle of the range rather than the extremes, because more combinations produce middling sums. This shapes the odds in games using multiple dice.

Roll openly for fair play. In a shared game, roll on a visible screen so everyone sees the result, keeping the play demonstrably fair, just as physical dice are rolled in view of all players.

Use a coin or number tool for other needs. For a simple two way choice, our Coin Flip is simpler, and for any custom range the Random Number Generator gives a fair number.

Common Dice Rolling Mistakes to Avoid

Believing a number is due. After a number has not come up for several rolls, it is not more likely next time; each roll is independent with equal chances for every face. Acting on the gambler's fallacy, expecting a result to be due, misunderstands how fair dice work.

Expecting multiple dice totals to be uniform. The sum of several dice is not equally likely across its range; middling totals are more common than extremes because more combinations produce them. Expecting every total to be equally likely misjudges the odds in games using multiple dice.

Rolling the wrong dice for the game. Using the wrong type or number of dice gives results that do not fit the game's rules. Check what dice your game requires and select them correctly, especially in role playing games that use several types.

Rerolling until you get what you want. Rolling repeatedly until a favourable result appears defeats the fairness that makes dice worthwhile. Accept the rolled result as the games intends, keeping the randomness genuine and the play fair to all.

For a simple two way choice, our Coin Flip is simpler, and the Random Number Generator gives a fair number in any range. To pick from a list, the Random Picker and Wheel Spinner select fairly.

Frequently Asked Questions

How do I roll dice online?

Choose the type of dice you need, a standard six sided die or a multi sided die used in role playing games, set how many to roll, and press roll. The tool generates a fair random result for each die, with every face equally likely, and shows the individual results and their total. Each roll is independent, so you can roll again for your next turn with fresh fair results, no physical dice required.

Are online dice fair?

Yes. A virtual dice roller uses a random number generator to give each face an equal probability, making it as fair as a well made physical die, and free from the imperfections real dice can have from manufacturing or wear. Each roll is also independent, so previous rolls do not influence the next. A properly implemented roller provides genuinely fair, unbiased results every time you roll, just like fair physical dice.

Can I roll multiple dice at once?

Yes. You can set the number of dice to roll together, so you can roll a single die or a handful at once, as many games require. The tool shows the individual result of each die along with their total, matching how games use multiple dice. Rolling several together is common in board and role playing games, where the sum of the dice determines the outcome of a move or action.

What are the different types of dice?

Beyond the standard six sided die, role playing games use a family of multi sided dice, commonly with four, eight, ten, twelve and twenty sides, among others. Different dice suit different purposes: a twenty sided die gives a wide range of outcomes for actions, while smaller dice suit damage or minor effects. A virtual roller can produce any of these instantly, which is especially convenient for games that use several different dice types in play.

Is a number more likely if it has not come up?

No. Each dice roll is an independent random event, so a number that has not appeared for several rolls is not more likely to come up next; every face has an equal chance every time. Believing a result is due after a dry spell is the gambler's fallacy, a common misunderstanding of probability. Fair dice, virtual or physical, have no memory of previous rolls, so each roll starts fresh with equal odds.

Why do totals from multiple dice cluster in the middle?

Because there are more combinations of individual dice that produce a middling total than an extreme one. For example, with two dice, only one combination gives the lowest possible total and one gives the highest, but several combinations give a total in the middle. This means the sum of multiple dice is more likely to land near the middle of its range, which gives games using multiple dice their characteristic feel and odds.

Can I use a dice roller for role playing games?

Yes, a dice roller is very useful for tabletop role playing games, which use a variety of multi sided dice for actions, damage and checks. You can roll the specific dice your game requires, single or multiple, and get fair results instantly without needing to carry physical dice. This is convenient for games that use several dice types, letting you roll whichever the rules call for at any moment during play.

Is the dice roller free?

Yes, it is completely free with no account and no usage limit. You can roll as many dice, of any type, as many times as you like, at no cost. It runs entirely in your browser on any device, so there is nothing to download or install, and each roll gives instant, fair random results with a total the moment you press roll, ready for your game or decision.
