How the Roll Is Generated
Each die is simulated independently using a uniform random integer generator: for a die with s sides, the result is Math.floor(Math.random() * s) + 1, which gives every face from 1 to s an equal 1/s chance of appearing. This is the same uniform-distribution approach used by standard virtual dice rollers — it is not a physics simulation of a tumbling cube, just a fair random draw over the die's face values. The total is simply the sum of all individual die results.
Why the Average Isn't the Most Likely Total
The theoretical average for a single fair die is (s + 1) / 2 — for a standard d6 that's 3.5, even though 3.5 can never actually be rolled. When you roll multiple dice and sum them, the distribution of the total clusters around N times that average rather than spreading evenly: with 2d6, a total of 7 is six times more likely than rolling a 2 or a 12, because there are more combinations of two dice that add up to 7. Rolling more dice makes extreme totals (all 1s or all max-value) increasingly rare relative to totals near the middle.

Frequently Asked Questions
Are the dice rolls truly random?
Each roll uses JavaScript's Math.random() to generate a uniform random integer between 1 and the number of sides, so every face has an equal chance of appearing. This is pseudorandom and suitable for games and simulations, but not cryptographically secure (unlike the site's password generator, which needs a stronger random source).
Why does the total for multiple dice cluster around the middle instead of spreading evenly?
When you sum multiple dice, there are more ways to combine individual rolls into a middle value than an extreme one. For example, with 2d6 there's only one combination that makes 2 (1+1) but six combinations that make 7, so totals near the average of N times (sides+1)/2 come up far more often than the minimum or maximum.
