About This Calculator
The Dice Roller generates random dice rolls for games, tabletop RPGs, probability experiments, and decision-making. You can roll multiple dice with customizable numbers of sides, from standard 6-sided dice to any number of sides you need.
Simply specify how many dice to roll and how many sides each die should have, then click "Roll Dice" to generate random results. The calculator shows individual die results and the total sum of all dice.
Formula & Calculation Method
Dice Rolling:
Random Number Generation:
Roll = Random integer between 1 and Number of Sides
Roll = floor(Random × Sides) + 1
Total:
Total = Sum of all individual rolls
Total = Roll₁ + Roll₂ + ... + Rollₙ
Each die roll generates a random integer between 1 and the number of sides. The total is the sum of all individual rolls. For fair dice, each face has an equal probability of appearing (1/n where n is the number of sides).
