How This Dice Roller Works
Each die roll generates a uniformly distributed pseudorandom integer between 1 and the die's maximum face value. When multiple dice are rolled, each is generated independently and summed for the total.
The formula for a single die is: Result = floor(random() × N) + 1, where N is the number of faces on the die.
Dice Types Explained
For example, rolling 3d6 (three six-sided dice) generates three independent random numbers each between 1 and 6, then adds them. The minimum possible result is 3, the maximum is 18, and the statistical average is 10.5.
Randomness note: This tool uses the browser's Math.random() pseudorandom number generator. While excellent for games and casual use, it is not a cryptographic-grade source of entropy.
Practical Examples
Ludo Game Night in Mumbai
Input: 1d6 (one six-sided die)
Result: Random value from 1 to 6 each turn
Use Case: Rahul's family in Mumbai lost their Ludo dice. They use this tool on a phone placed in the centre of the board for everyone to see.
D&D Character Creation in Bangalore
Input: 4d6 (four six-sided dice, drop lowest)
Result: e.g., rolls of 5, 3, 6, 2 → keep top three (5+3+6) = 14
Use Case: A Bangalore RPG group uses this roller during character creation, manually noting the highest three from each 4d6 roll for ability scores.
RPG Combat Encounter in London
Input: 1d20 for attack, then 2d6 for damage
Result: e.g., attack roll = 17 (hit!), damage = 4+5 = 9
Use Case: An online D&D session where the DM uses this tool as a quick backup when their physical dice are out of reach.
Probability Class Exercise in Delhi
Input: 2d6 rolled 20 times
Result: Distribution of sums from 2 to 12 across 20 rolls
Use Case: A maths teacher in Delhi demonstrates probability distributions by having students roll 2d6 repeatedly and tally the results on a whiteboard histogram.
What Is a Dice Roller?
A dice roller is a virtual tool that simulates throwing physical dice by generating random numbers within the correct range for each die type. It replaces the need for physical polyhedral dice, making it useful anywhere you have a phone, tablet, or computer.
This tool is built for board game players, tabletop RPG groups, teachers demonstrating probability, and anyone who needs a quick fair random number. It supports seven standard die types covering everything from classic Ludo (D6) to full Dungeons & Dragons gameplay (D4 through D20 and D100 percentile rolls).
The key advantage is instant access to any combination of dice without carrying a physical set. You can roll up to 10 dice at once, see each individual result, and track your complete roll history during a session — especially useful for long RPG encounters where dozens of rolls occur.
Sources and Methodology
Dice outcomes are generated using the JavaScript Math.random() function, which produces pseudorandom floating-point numbers uniformly distributed between 0 and 1. The result is scaled to the die range using the standard floor-and-shift method widely taught in computer science and used across gaming applications. This approach produces a fair, unbiased distribution across all face values for any standard die type.
Frequently Asked Questions
Yes, this dice roller is 100% free. There are no hidden charges, no signup required, and no premium features. Roll as many times as you want with no limits.
Absolutely. All dice rolls are generated entirely in your browser using JavaScript's built-in random number generator. No roll data is sent to any server, stored in any database, or tracked in any way.
This tool uses the Math.random() function built into your browser's JavaScript engine, which produces pseudorandom numbers suitable for games and casual decisions. For cryptographic or scientific purposes requiring true randomness, a hardware random number generator would be more appropriate.
Seven standard dice types are available: D4 (tetrahedron), D6 (standard cube), D8 (octahedron), D10 (pentagonal trapezohedron), D12 (dodecahedron), D20 (icosahedron), and D100 (percentile). These cover virtually all tabletop RPG and board game needs.
Yes, you can roll anywhere from 1 to 10 dice simultaneously. Each die is rolled independently, and the tool shows every individual result plus the combined total sum.
Yes. The tool includes all standard polyhedral dice used in Dungeons and Dragons, Pathfinder, and other tabletop RPGs — D4, D6, D8, D10, D12, and D20. You can quickly roll attack dice, damage dice, or ability checks.
No. The roll history is kept only during your current browser session and is cleared when you close or refresh the page. No data is saved to your device or any server.
Absolutely. Select D6 and roll 1 die for classic board games like Ludo, Snakes and Ladders, or Monopoly. It is a perfect replacement when physical dice are unavailable.
