How to use an online dice roller for tabletop games

Published 25 May 2026 · 4 min read

An online dice roller is handy when dice are missing, a remote player needs a visible roll, or a table needs faster totals for big damage pools. The key is choosing the right die type before the roll and making the rule clear to the group.

Choose the die first

Most tabletop games use standard dice names: D4, D6, D8, D10, D12, D20 and D100. The number after the D is the number of sides. Use the Dice Roller when you need any of those dice, multiple dice at once, or a custom-sided die.

Use presets for common rolls

Presets are faster when the roll is familiar. Use Roll 2d6 for two six-sided dice, Roll d100 for percentile tables, and Random Number 1-20 for a quick D20 roll.

Handle multiple dice openly

For damage rolls, spell effects or dice pools, set the number of dice before rolling. If the table needs to verify the result, read both the individual dice and the total. That small habit avoids most "wait, what did you roll?" moments.

Rolling character stats

For D&D-style ability scores, use Roll 4d6 Drop Lowest. It shows the four dice, drops the lowest and totals the remaining three. For the details behind that method, read the 4d6 drop lowest guide.

When online dice are a good fit

• Remote or hybrid sessions where not everyone can see physical dice.
• Large damage pools where mental arithmetic slows play.
• Classroom probability lessons where repeatable examples matter.
• Board games when the original dice are lost or packed away.
• Custom homebrew systems that need unusual die sizes.

Online dice do not need to replace physical dice. They are a fast backup and a clean way to handle rolls that would otherwise interrupt the rhythm of the table.
