More Useful Guidance
Understanding dice notation and totals
Standard tabletop dice are usually written as d4, d6, d8, d10, d12, d20 or d100, where the number after the d tells you how many faces the die has. If you roll several dice, you see each roll separately before they are added together. Any modifier is added or subtracted afterwards.
Example: rolling 2d6 + 3
Choose two six-sided dice and a +3 modifier. If the dice show 4 and 6, the raw dice total is 10 and the final result is 13. The modifier did not make 4 or 6 more likely; it was simply applied after both equal-chance dice had already been rolled.
Use the right dice for the rule
A d20 and a d6 both return a number, but they have very different possible results. Use the die that matches the rules of the game. Custom sides are useful for homemade games when you need a number of equally likely choices that a standard die does not provide.
Dice Roller vs Random Number Generator
Dice Roller is better when the rules are based on dice, especially when you are rolling several dice or using a modifier. Random Number Generator is better for a flat range such as 1–37 or for decimal values. Rolling two dice is not the same as generating one number between their minimum and maximum because some dice totals are more likely than others.
How the Result Is Chosen
Fair selection
Every face on a die has the same chance. Rolling more than one die does not change that, and a modifier only changes the final total.
Privacy
No account or personal information is needed to roll the dice.
Common Questions
Can I roll a d20?
Yes. d20 is one of the built-in presets.
Can I roll several dice together?
Yes. Choose how many dice you want to roll before pressing the button.
What does a modifier do?
A modifier is added to or subtracted from the total after the dice are rolled.
Are all sides equally likely?
Yes. Every face on a die has the same chance.
Is rolling 2d6 the same as generating 2 to 12?
No. With 2d6, middle totals such as 7 can be made in more ways than 2 or 12, so the totals do not have equal chances.
Can I use a custom number of sides?
Yes. Use the custom-sides option when you need something other than the standard dice.
