What is a dice roller?

What is a dice roller? A dice roller is a free online tool that simulates rolling one or more virtual dice, including common tabletop formats such as D4, D6, D8, D10, D12, and D20. It is commonly used for RPG combat, board game turns, classroom probability demos, and any situation where you need quick, fair random results without physical dice.

How it works.

01 / 03
Choose the Die Type
Select the exact die you need for the moment, from a fast D6 board-game roll to a D20 attack check or a D8 damage roll during an RPG session.
02 / 03
Set the Dice Count
Pick how many dice to roll at once when a rule calls for multiple damage dice, character creation rolls, or repeated probability checks in one action.
03 / 03
Read Individual Rolls and Total
The tool shows every die result plus the sum, which makes it practical for resolving combat damage, movement counts, loot tables, and quick house-rule decisions without mental math.

When you'd use this.

Tabletop RPG Sessions

Use the roller during D&D, Pathfinder, or other TTRPG sessions when you need attack rolls, saving throws, initiative, spell damage, or healing results without reaching for physical dice. Seeing each die and the total on screen is especially useful for remote games and shared screens.

Board Games and Travel Play

If a die is missing from the box or you are playing away from home, the tool acts as a clean replacement for physical dice. The D6 default covers many classic games immediately, while other die sizes help with modern hobby games that use nonstandard dice.

Probability Checks and Fair Decisions

Teachers, players, and facilitators can use the roller for classroom demos, random turn order, challenge prompts, or any moment that needs an impartial number with dice semantics instead of a plain random integer.

About Dice Roller.

Roll any standard dice type — D4, D6, D8, D10, D12, or D20 — with support for rolling up to 6 dice at once. See individual results and the total sum. Perfect for D&D, Pathfinder, board games, and any tabletop game that needs dice.

Frequently asked.

What dice can I roll with this dice roller?+
You can roll D4, D6, D8, D10, D12, and D20, which covers the most common dice used in tabletop RPGs, board games, and general random-number tasks.
Can I roll more than one die at a time?+
Yes. The tool supports rolling up to 6 dice in one action, then shows both the individual results and the combined total so you can resolve multi-die rolls quickly.
Is an online dice roller fair enough for games?+
For normal play, yes. Each roll is generated independently so every face has an equal chance, which makes it suitable for casual sessions, remote games, and replacing missing physical dice.
When should I use a D20 instead of a D6?+
Use a D20 when the game rule specifically calls for a 20-sided die, such as attack rolls, saving throws, or ability checks in many RPG systems. Use a D6 for standard board-game movement, simpler damage rolls, or common randomization tasks.
