Classic tool

Online Dice Roller

Roll d4, d6, d8, d10, d12, d20, d100 or custom dice with total, roll list and modifier.

Use this online dice roller when you need a fast, fair result without reaching for physical dice. It works well for tabletop RPG sessions, board games, classroom activities, light random picks and any situation where a number needs to be generated on the spot.

Choose the die type, set how many rolls you want and add a positive or negative modifier when the rules call for it. The tool returns the final total, every individual roll, the highest value, the lowest value and the average, making it useful for simple checks as well as multi-dice actions.

If your game or workflow uses unusual face counts, switch to the custom die option. That lets the same page handle anything from a classic d6 to d30, d50, d100 or another custom setup without installing an app or extension.

Useful for RPG sessions, board games, classroom activities and quick random decisions.

How to use this dice roller

Pick the die, enter the number of rolls and press the button to generate the result. If the rules include bonuses or penalties, add the modifier before rolling. The notation field helps you verify the exact setup used for the throw.

When a custom die helps

The custom option is useful for house rules, prototypes, classroom exercises, simulations and any system that does not stop at the standard d4, d6, d8, d10, d12, d20 or d100. You keep one page for all those cases instead of jumping between separate tools.

Reading the output

The final total already includes the modifier. The individual list shows each face rolled, while highest, lowest and average help you review how the throw behaved overall. That is practical for damage, initiative, probability tests and repeated comparisons.

How to use Online Dice Roller

Open the tool, fill in the fields with the data you already have and generate the result step by step. If you want to compare scenarios, change one field at a time so it is easier to understand the impact of each value.

When Online Dice Roller is useful

The goal here is simple: Roll d4, d6, d8, d10, d12, d20, d100 or custom dice with total, roll list and modifier. It works well for quick checks, planning, study and review before you move to a final decision or document.

What to review before using the result

Check units, labels, numbers, timing and any context that can change the meaning of the output. If the result will be used in a quote, technical task, published page or report, finish with a manual review.

Frequently asked questions

What should I prepare before using the tool?

Keep the key values, labels and units ready before filling in the fields. Cleaner inputs make the final result easier to review and compare.

Can I test different scenarios on the same page?

Yes. The safest approach is to change one field at a time, compare the outputs and note which value actually changes the final answer.

Is the result ready to use without checking it?

It is better to treat it as support. Review the output once more before using it in a quote, document, spreadsheet, technical task or published page.
