Understanding Dice Notation (e.g., "2d6+5")

If you're new to tabletop role-playing games (TTRPGs), you'll often see shorthand like "2d6" or "1d20+5". This is called dice notation, and it's a simple way to describe a roll.

Let's break down a common example: 2d6+5

• 2d6+5: The first number ("2") tells you how many dice to roll. In this case, you roll two dice.
• 2d6+5: The "d" stands for "die" or "dice". The number immediately after it ("6") tells you the type of die to use (how many sides it has). "d6" means a 6-sided die.
• 2d6+5: Any number at the end is a "modifier". This is a flat number you add (or subtract) from the total.

So, "2d6+5" means: "Roll two 6-sided dice, add their results together, and then add 5 to that total."

Dice Types Explained

While the standard 6-sided die is famous, TTRPGs use a variety of polyhedral dice. Here are the most common ones supported by our roller:

• d4 (4-sided): A pyramid shape. Often used for small damage rolls, like from a dagger.
• d6 (6-sided): The classic cube. Used for many things, including rolling character stats and weapon damage.
• d8 (8-sided): An octahedron. Commonly used for damage rolls from larger one-handed weapons like longswords.
• d10 (10-sided): A pentagonal trapezohedron. Used for damage from heavy weapons and often rolled in pairs (d100) to get a number from 1 to 100.
• d12 (12-sided): A dodecahedron. Typically used for damage from the biggest weapons, like a greataxe.
• d20 (20-sided): An icosahedron. This is the most important die in games like Dungeons & Dragons. It's used for almost every major action: determining if you hit an enemy, dodge a spell, or persuade a guard.
• d100 (Percentile): Also known as percentile dice. Typically rolled as two d10s to generate numbers from 1-100, used for random tables, loot drops, and percentage-based outcomes.

Frequently Asked Questions

Can I roll different types of dice at the same time?

Currently, you can only roll one type of dice per roll. To roll multiple types (like a d20 and a d6), simply make separate rolls.

Is Dice Roller mobile-friendly?

Absolutely! The site is fully responsive and works great on smartphones, tablets, laptops, and desktops — no downloads required.

How random are the dice rolls?

Dice results are generated using JavaScript's Math.random(), which provides sufficient randomness for casual gameplay.

How long is my roll history saved?

Your roll history stays saved in your browser's local storage unless you clear your browser cache or click "Clear History."
