Dice Roller
The Dice Roller simulates rolling dice with customizable number of sides and quantity. Common dice include d4, d6, d8, d10, d12, d20, and d100, used in tabletop games like Dungeons and Dragons. You can roll multiple dice at once, see individual results and the total, and view a history of rolls. This tool is perfect for board games, RPGs, probability demonstrations, or any scenario requiring random number generation.
Formula
Dice types: - d4: 1-4 (tetrahedron) - d6: 1-6 (cube, standard) - d8: 1-8 (octahedron) - d10: 1-10 (pentagonal trapezohedron) - d12: 1-12 (dodecahedron) - d20: 1-20 (icosahedron) - d100: 1-100 (percentile) Random: crypto.getRandomValues()
Example
Roll 2d6 (two 6-sided dice): Result: 4, 6 Total: 10 Roll 1d20 (one 20-sided die): Result: 17 Roll 4d6 drop lowest (D&D stats): Rolls: 6, 3, 5, 4 Drop 3, total: 15
How to Use
- Select the dice type (d4, d6, d8, d10, d12, d20, d100, or custom)
- Set the number of dice to roll
- Optionally add modifiers (drop lowest, keep highest)
- Click roll to generate random results
- Review individual rolls and the total
Frequently Asked Questions
What dice are used in Dungeons and Dragons?
D&D uses seven dice: d4, d6, d8, d10, d12, d20, and d100 (percentile). The d20 is the most commonly used for attack rolls, saving throws, and ability checks. The d4, d6, d8, d10, and d12 are used for damage and other effects.
Is the dice roller truly random?
Yes. The tool uses the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure random numbers. Each die has an equal probability of landing on any face, just like a physical die.
Can I roll multiple dice at once?
Yes. You can specify the number of dice to roll (e.g., 3d6 rolls three 6-sided dice). The tool shows individual results and the total. You can also apply modifiers like 'drop lowest' or 'keep highest'.
What is the average roll for a d6?
The average roll for a fair d6 is 3.5 (the average of 1, 2, 3, 4, 5, 6). For 3d6, the average total is 10.5. For 4d6 drop lowest (used for D&D stats), the average is about 12.24.
Can I use custom dice with non-standard sides?
Yes. The tool supports any number of sides from 2 to 1000. You can create custom dice like d3, d5, d7, or d1000. This is useful for custom game rules or probability experiments.
