How to Use

  1. 1 Pick a dice type — D4, D6, D8, D10, D12, D20, or D100
  2. 2 Set how many of that die to roll (1 to 100)
  3. 3 Add more dice types if you want to mix them
  4. 4 Enter a modifier to add to or subtract from the total
  5. 5 Press Roll Dice and read the total plus each die result
  6. 6 Check the roll history to compare previous throws

Features

  • All seven standard polyhedral dice: D4, D6, D8, D10, D12, D20, D100
  • Roll up to 100 of each die in a single throw
  • Mix dice types — e.g. 2d6 + 1d20 in one roll
  • Add a positive or negative modifier to the total
  • See every individual die face, not just the sum
  • Roll history keeps your recent throws for quick comparison

Why it Matters

Tabletop games, board games, and quick decisions all lean on dice, and physical dice are easy to lose or leave at home. A virtual roller gives you fair, instant rolls for any dice combination, shows every individual result, and never needs a flat surface. It is the dice tray that lives in your browser.

What this tool does

The Dice Roller rolls any combination of standard dice for you. Choose a die type, set how many to roll, mix in other dice, add a modifier, and hit Roll Dice. You get the grand total, each group’s subtotal, and every individual die face — perfect for tabletop RPGs, board games, or any moment you need a fair random number.

How it works

Each die produces a uniformly random integer between 1 and its number of sides. The tool sums every die, applies your modifier, and reports the result as an expression like 2d6 + 1d20 + 1 = 28. It also shows the theoretical minimum and maximum so you can see the possible range. The rolling logic is a pure function, so the odds are exactly even on every face.

Privacy

Everything runs locally in your browser. Your rolls, modifiers, and history are never uploaded, logged, or stored.

Frequently Asked Questions

Which dice can I roll?
All seven standard polyhedral dice: D4, D6, D8, D10, D12, D20, and D100 (percentile). You can roll up to 100 of any single die at once, and combine different dice types in the same throw, such as 2d6 plus 1d20.
Are the rolls actually random?
Yes. Each die uses your browser's built-in random number generator to pick a face uniformly between 1 and the number of sides. Every roll is independent, so a previous result never influences the next one.
What does the modifier do?
The modifier is a flat number added to the grand total after all dice are summed. It can be positive or negative, which matches how tabletop games apply bonuses and penalties — for example, 1d20 + 5 or 2d6 − 1.
Can I see each individual die, not just the total?
Yes. After every roll the result card lists each die's face value alongside the per-group subtotal and the grand total, so you can verify the maths or read specific dice for game rules.
Is anything sent to a server?
No. The dice roller runs entirely in your browser. Your rolls, modifiers, and history are never uploaded, logged, or stored anywhere.

How Dice Probability Works: Odds, Modifiers, and Fair Rolls

Understand dice probability the way games actually use it — flat versus bell-curve odds, what a modifier really changes, why more dice means a tighter spread, and how to read a multi-die roll correctly.
