Dice Roller
Roll virtual dice for tabletop RPGs, board games, probability testing, or any situation requiring random number generation.
About the Dice Roller
Our Dice Roller simulates physical dice rolling for tabletop RPGs, board games, or any scenario requiring random number generation. Whether you need a simple d6 for board games, complex dice combinations for RPGs like Dungeons & Dragons, or probability testing for statistical analysis, this tool provides flexible and customizable dice rolling options.
Features of Our Dice Roller:
- Multiple Dice Types: Roll d4, d6, d8, d10, d12, d20, d100, or custom-sided dice
- Roll Modifiers: Add, subtract, multiply, or divide modifiers to your rolls
- Special Rules: Roll with advantage, disadvantage, or drop highest/lowest dice
- Batch Rolling: Roll multiple sets at once and view statistics
- Visual Results: See all individual dice values with color-coding for critical values
- Statistical Analysis: View min, max, and average values for multiple rolls
Understanding Dice Notation:
| Notation | Description | Example | Possible Results |
|---|---|---|---|
| d6 | One 6-sided die | 1d6 | 1, 2, 3, 4, 5, 6 |
| 3d8 | Three 8-sided dice, summed | 3d8 | 3 to 24 |
| 2d20 + 5 | Two 20-sided dice plus 5 | 2d20 + 5 | 7 to 45 |
| d100 | Percentile die (1-100) | 1d100 | 1 to 100 |
Common Uses for Dice Rolling:
- Tabletop RPGs: Dungeons & Dragons, Pathfinder, Call of Cthulhu, and other role-playing games
- Board Games: Replace physical dice in games like Monopoly, Risk, or Yahtzee
- Decision Making: Use dice to make random choices or determine outcomes
- Education: Teach probability and statistics with visual demonstrations
- Game Development: Test random number generators and probability distributions
- Randomization: Generate random numbers for contests, giveaways, or selecting winners
Special Rolling Rules Explained:
- Advantage: Roll twice and take the higher result (common in D&D 5th Edition)
- Disadvantage: Roll twice and take the lower result
- Drop Lowest: Roll extra dice and remove the lowest results (e.g., roll 4d6 and drop the lowest for D&D character creation)
- Drop Highest: Roll extra dice and remove the highest results
Frequently Asked Questions
Are these dice rolls truly random?
Yes! We use a cryptographically secure random number generator to ensure fair and unpredictable results, just like physical dice.
What is advantage/disadvantage in dice rolling?
These are special rules from games like D&D 5E. Advantage means roll twice and take the higher result, while disadvantage means roll twice and take the lower result.
How do I roll for a D&D character's ability scores?
The standard method is to roll 4d6, drop the lowest die, and sum the remaining three dice. Do this six times for your six ability scores.
What's the difference between a d100 and percentile dice?
They're the same thing. A d100 generates a random number from 1-100, which can be used for percentages. In physical dice, this is often rolled using a d10 and a percentile d10.
Can I use this for games that require special dice?
Yes! You can use the custom dice option to create dice with any number of sides, accommodating special game systems.
Why would I want to drop highest or lowest dice?
This technique is used in many RPGs to "smooth out" probability curves, making extreme results less likely. For example, "4d6 drop lowest" gives a bell curve favoring middle values.
