What is a Dice Roller?
A dice roller is a digital tool that simulates rolling physical dice. Whether you're playing Dungeons & Dragons, board games, or need random numbers, this online dice roller provides instant, fair results. It supports standard dice (D4, D6, D8, D10, D12, D20, D100) and custom dice of any size.
How to Use the Dice Roller
1. Select your dice: Click a preset button (D4-D100) or enter a custom size (e.g., D30).
2. Choose quantity: Set how many dice to roll (1-10).
3. Pick a mode: Enable Advantage/Disadvantage for D&D 5e mechanics if needed.
4. Roll: Click "Roll Dice" to generate results with animation.
5. Review: View individual results, sum, history, and session statistics instantly.
Common Use Cases
Tabletop RPGs: Roll for D&D, Pathfinder, Warhammer, and other role-playing games.
Board Games: Generate random numbers for Catan, Risk, and other strategy games.
Probability Study: Run multiple rolls to analyze odds and understand averages.
Random Selection: Use dice to make fair, unbiased choices in any situation.
What is Advantage and Disadvantage?
In D&D 5e, Advantage lets you roll 2d20 and use the highest result. Disadvantage is the opposite: roll 2d20 and use the lowest. This tool automates that mechanic instantly.
Can I roll custom dice?
Yes! Enter any dice size in the "Custom Dice" field (e.g., D30, D50, D1000). The roller supports any positive integer.
Is this roller truly random?
Yes. This tool uses JavaScript's cryptographically sound Math.random() for fair rolls. Each result is independent and unbiased.
How many rolls does the history keep?
The tool stores the last 20 rolls per session. History resets when you close the tab or clear it manually using the "Clear History" button.
What do the statistics mean?
The stats show your session's average roll, lowest result, highest result, and total number of rolls. Use these to track probability patterns over multiple rolls.
Can I roll multiple dice at once?
Absolutely! Set "Number of Dice" to any value from 1-10. The tool displays each individual result and the sum for quick reference.
