Who uses the Dice Roller

Board games

A missing die should not end game night. Keep this page open on a phone or tablet in the middle of the table, and press Full screen so that everyone can see each roll.

Classroom maths

Dice are a simple way to teach addition and probability. Students can roll two dice many times, record the totals, and compare what they find with the odds table on this page. The download gives them data ready for a spreadsheet.

Tabletop role-playing games

Many games call for several six-sided dice at once, for ability scores or damage. Set the number you need and the total is worked out for you. This tool only rolls six-sided dice, so you will need something else for other shapes.

Quick decisions in a group

Give each person or option a number from one to six, then roll. It is a fast way to settle who goes first or who takes the next turn, and everyone can see the result together.

Practising odds and strategy

Players of backgammon and other dice games often want to understand which totals are likely. Roll two dice a hundred times and download the results, and you can compare your own counts with the table on this page. It takes far less time than rolling by hand, and it gives you a tidy record to look back on.

Odds when you roll two dice

Each die is equally likely to land on any number, but totals are not. There are 36 possible results with two dice, and more of them add up to 7 than to anything else.

Dice Roller questions

Are the rolls really random?

Each die uses your browser's cryptographic random number generator, with an equal chance for every face. The result is chosen first, and the animation then lands on it. Past rolls have no effect on the next one.

Are these like real dice?

They look and behave like standard six-sided dice, with opposite faces that add up to seven. Unlike a physical die, they have no worn edges or uneven weight, so they cannot favour a number.

How many dice can I roll?

You can roll up to 12 at the same time. If you need more, roll a second batch and add the totals together. Each time you re-roll a single die, the new total is added to your past rolls.

Can I roll a 20-sided die?

Not with this tool, which only rolls six-sided dice. For a similar result, the number wheel can choose from 1 to 20 instead.

Is my roll history saved?

Past rolls stay on the page until you clear them or close it, and your rolls are not sent to a server. Use Copy or Download CSV to keep a record.

Why does a total of 7 come up so often with two dice?

Because there are more ways to make it. Six different combinations add up to 7, while only one makes 2 and only one makes 12. The table on this page shows the chance of every total.
