How do you calculate multiple dice rolls?

If you want to know how likely it is to get a certain total score from rolling two or more dice, it’s best to fall back on the simple rule: Probability = Number of desired outcomes ÷ Number of possible outcomes.

What is fudging a dice roll?

Fudging is reporting the result of a dice roll, made in secret (e.g. behind a GM screen), to be something other than what it was. This is generally only considered to be fudging when done by the GM, and when done by any other player it is considered cheating (although some rare groups may tolerate this).

How do you calculate average dice?

Another option for finding the average dice roll is to add all of the possible outcomes together then divide by the number of sides the die has. For example, to find the average dice roll of 1d4 you would add 1, 2, 3, and 4 together and divide by 4.

Is it okay to fudge rolls as a DM?

Should you fudge dice rolls?

You should almost never “fudge” rolls. That is, if you roll the dice to see what happens, always accept whatever the dice tell you. Die rolls exist in games for a reason, after all.
