About the Dice Roller

Each roll samples a uniform distribution over the die's faces — every outcome from 1 to s is equally likely. The sum of n dice follows a bell-like triangular distribution centered on the expected value n × (s + 1) ÷ 2, which is why totals near the middle are far more common than extremes.

Fairness Notes

This roller uses the browser's pseudo-random generator: fine for games and sampling, not for cryptography. For security-sensitive randomness (draws, lotteries), use a dedicated cryptographically secure generator instead.
