Dice Roller

Roll any number of dice and see the breakdown of your results.

Set the number of dice (1–10) and sides, then roll. The default 2d6 gives results from 2 to 12.

What is the Dice Roller?

A dice roller is a virtual simulator that generates random numbers between 1 and the number of sides on your chosen die. It mimics the unpredictability of physical dice rolls, letting you roll standard six-sided dice, 20-sided polyhedral dice used in D&D, or custom dice with 2, 4, 8, 10, 12, 100, or any number of sides. Each roll is mathematically random and fair.

How it works

The tool uses a random number generator to pick a value between 1 and the die's maximum face value. If you roll multiple dice at once, it generates a separate random number for each die and sums them together. The results appear instantly on screen, and most dice rollers keep a history of recent rolls so you can review what was drawn.

Examples

InputResultNotes
1d20 (one 20-sided die)Random number between 1 and 20, e.g. 14Standard for D&D attack rolls and skill checks
3d6 (three six-sided dice)Sum of three random numbers, e.g. 14 (rolled 5, 4, 5)Common in board games and RPG character stat generation
2d10 (two 10-sided dice)Sum of two random numbers, e.g. 15 (rolled 7, 8)Often used in percentile rolls when combined as d100

How to use the Dice Roller

  1. Select the number of dice you want to roll (e.g. 2, 3, or 1)
  2. Choose the type of die by number of sides (d4, d6, d8, d12, d20, d100, or custom)
  3. Click the Roll button to generate random results
  4. View your total sum and individual die results on screen
  5. Check your roll history to see previous rolls if needed
  6. Roll again instantly without resetting

Benefits

  • Faster than finding and rolling physical dice, especially late at night
  • Fair and unbiased randomness every time—no weighted or lost dice
  • Supports any die type: standard six-sided, polyhedral (d20, d12, etc.), or fully custom
  • Roll multiple dice at once and get instant totals without mental math
  • Keep a searchable history of rolls for game records or dispute resolution
  • Free and works in any browser—no downloads, apps, or sign-ups needed

Tips & common mistakes

Common mistakes

  • Forgetting to select the correct number of sides before rolling (a d20 is different from a d6)
  • Not checking the individual die results when you only need one die's output (e.g. a single d20), not the sum
  • Assuming the tool is biased because you rolled low several times in a row—randomness naturally clusters

Tips

  • If you play D&D online (Roll20, Fantasy Grounds, Discord bots), many platforms have built-in dice rollers, but a standalone tool is handy for quick decisions at the table
  • For tabletop RPGs, roll in front of everyone or share your screen to keep the game transparent and fun
  • Use this tool to settle arguments fairly—flip a coin (1d2) or roll a d100 for tie-breakers

Frequently asked questions

Is this dice roller fair and random?

Yes. The tool uses a cryptographically secure random number generator, so every result has an equal chance. There's no bias toward high or low numbers.

Can I roll more than 10 dice at once?

Most dice rollers allow you to roll as many dice as you want in a single roll. Some may limit very large batches for performance, but 20+ dice is usually fine.

What dice types does this support?

Standard types include d4, d6, d8, d10, d12, d20, and d100. You can also enter a custom number of sides if your game uses unusual dice.

Can I save or export my roll history?

Most dice rollers show recent rolls on screen. Some tools let you take a screenshot or copy results, but permanent saves depend on your browser's storage settings.

What's the difference between 2d6 and d12?

2d6 rolls two six-sided dice and sums them (range 2–12), while d12 rolls one 12-sided die (range 1–12). Both can reach 12, but 2d6 favours middle values (7 is most common), and d12 is perfectly even across 1–12.

Can I use this for gambling or betting?

While the roller itself is fair, we don't recommend using it for money bets. Use it for games, decisions, and creative fun instead.
