How do I roll dice online?

Choose a die (d4, d6, d8, d10, d12, d20 or d100), pick how many to roll, then press Roll. The dice tumble and show each result with the total.

Is the online dice roller fair?

Yes. Each die uses your browser’s secure random number generator, so every face has an equal chance, just like a perfectly balanced real die.

Can I use it for D&D?

Yes. It has every standard tabletop die, a modifier box for bonuses and penalties, and advantage and disadvantage for the d20. For example, a d20 with advantage and +5 rolls two d20s, keeps the higher and adds 5.

What are advantage and disadvantage?

In Dungeons and Dragons 5th edition, advantage means you roll a d20 twice and take the higher result, and disadvantage means you take the lower. Choose a single d20 and pick Advantage or Disadvantage.

How do I roll two dice?

Select a d6 and set the number of dice to 2. You get each die and the total, which is what you need for games like Monopoly, Backgammon and Craps.

What are the odds when rolling two dice?

A total of 7 is the most likely, at 6 chances in 36 (16.7%). The table on this page lists the odds for every total from 2 to 12.

Can I roll a custom die?

Yes. Choose Custom and enter any number of sides from 2 to 1,000, for a d3, d30, d1000 or anything else.

Can I add or subtract a modifier?

Yes. Enter a modifier from -100 to 100 and it is added to the total. The result line shows the dice and the modifier so you can check the sum.

How many dice can I roll at once?

Up to 20 dice in one roll. Your recent rolls are listed so you can look back at them.

Does it work on a phone? Is it free?

Yes to both. It works in any phone or desktop browser, needs no sign-up or download, and nothing you roll is stored or sent anywhere.
