Dice Roller

The Dice Roller simulates rolling polyhedral dice commonly used in tabletop role-playing games like D&D, Pathfinder, and other systems. Each roll uses a cryptographically secure random number generator for fair results.

How to Use

1. Select a die type (d4, d6, d8, d10, d12, d20, or d100)
2. Set the number of dice to roll (1–100)
3. Optionally add a positive or negative modifier
4. Click "Roll" or use a quick preset
5. View individual die results, total, and running statistics

Dice Notation

Standard dice notation uses the format NdS+M where:

• N = number of dice to roll
• d = die (separator)
• S = number of sides on each die
• +M = modifier added to the total (optional)

For example, 2d6+3 means roll two six-sided dice and add 3 to the total.

Common Dice Types

• d4 — Tetrahedron. Used for small damage (daggers) and minor effects
• d6 — Cube. The most common die, used in many board games
• d8 — Octahedron. Medium weapon damage, hit dice
• d10 — Pentagonal trapezohedron. Damage, percentile rolls
• d12 — Dodecahedron. Heavy weapon damage (greataxe)
• d20 — Icosahedron. Attack rolls, ability checks, saving throws
• d100 — Percentile. Wild magic, loot tables, random encounters
