About the
The Dice Roller throws virtual dice of any common size, from a four-sided die up to a hundred-sided one, and shows the individual results alongside the total. Pick the die type and how many to roll, then roll as many times as you like, with the last few rolls kept on screen. It is meant for tabletop games, classroom probability exercises and any situation where you need a fair number and no dice to hand.
Where people use the
- Rolling for a tabletop game when the dice are in another room.

How to use the
- 1
Choose the die type
Pick d4, d6, d8, d10, d12, d20 or d100. Six-sided dice are drawn with pips like a real die.
- 2
Set how many dice
Enter any number from 1 to 20. The button label updates to match, so 3d6 means three six-sided dice.

Roll again and compare
Recent rolls stay listed below, which is useful when you are checking how often a result comes up.
Tips and best practices
- Leave the history on screen to compare several rolls instead of one.
- Roll each die size separately when your pool mixes sizes.
- Remember repeats are normal; independence means they happen.
Frequently asked questions
Are the rolls fair?
Each die uses the browser random function, which gives an even spread across the possible values. It is fine for games and demonstrations, and not suitable for gambling or anything where money depends on unpredictability.
Can the same result come up twice?
Yes. Every roll is independent, so repeats are expected rather than a sign of a problem.
What does 3d6 mean?
Three six-sided dice, which is the standard tabletop notation. The first number is how many dice, the second is how many sides each die has.
Why is there a maximum of 20 dice?
To keep the results readable on one screen. If you need a larger pool, roll in batches and add the totals.
Can I roll different dice sizes at once?
No. Roll each size separately and add the totals yourself, which is how mixed pools are usually handled at the table anyway.
