D100 Dice Roller
Roll a 100-sided die immediately. Use outcomes from 1 to 100 for percentile checks. Change the number of dice and check the outcomes and their sum. You can copy the results or save them as TXT.
What you can do
Roll dice and see each result and the total
3D dice roll and settle on their results. Six-sided dice show pips; polyhedral dice show numbers. When rolling multiple dice, the total for that roll is shown too.

Settings, finalized outcomes, and history are saved in this browser. The same results are restored after a reload or when you return from another page.
How to use
Check the rolling conditions
One 100-sided die is selected. Change the number of sides or dice as needed.
Roll dice
Check the outcomes and total. Change the number of rolls in advanced settings only when repeating the same set.
Roll again or clear history
“Roll again” keeps previous results and adds new ones to the history. Copy the history or save it as TXT. Use “Clear history” to remove all recorded rolls.
Useful when
Percentile checks from 1 to 100
Use an outcome from 1 to 100 to compare with the target value in the game.
How to read outcomes and records
D100 produces one value from 1 to 100
Two 10-sided dice show the tens and units digits. Their combined value is recorded as one outcome, and 00 with 0 is treated as 100.
Rolling again and clearing history
Each roll adds new results to the history. “Clear history” removes only recorded rolls and keeps your settings. Changing settings alone does not alter past results.
How to read D100
Combine the tens and units digits of two 10-sided dice. 70 with 3 gives 73, and 00 with 0 gives 100. Outcomes range from 1 to 100.
Frequently asked questions
Does it also show whether a check succeeded or failed?
This page displays dice outcomes. It does not automatically apply game target values or modifiers.
Can the same result occur repeatedly?
Yes. Each roll is determined independently, with no adjustment to avoid previous outcomes.
Do previous results change if I change the number of sides or dice?
Settings apply to the next roll. Each record keeps the sides and dice count used for that roll.
Will results disappear when I reload?
Settings and history remain in this browser. Cleared history or deleted site data cannot be restored, and history does not transfer to another browser. If storage is unavailable, export the history as TXT.
