When the Dice Roller seems to misbehave, the cause is usually one of two things: something stopped the tool from running, or it ran but the result is not usable. This guide starts with the fastest checks, then walks through the common problems and exact fixes.
Quick Checks First
- Refresh the page - a stalled session is the most common cause of nothing happening.
- Confirm the input is not empty and actually contains what you meant to submit.
- Try the smallest possible input; if that works, the issue is size, not the tool.
- Turn off browser extensions that block scripts, then reload and test again.
- Update or switch browsers if the problem repeats across sessions.
Common Problems and How to Fix Them
The roll shows an error.
Check the NdX format - a count, the letter d and a side count such as 4d8 make a valid roll.
I rolled the wrong dice.
Read the notation once more before confirming - 2d6 and 6d2 describe very different rolls.
The total does not match the dice.
The total adds every die shown - re-add the listed values if you think it is off, since each face is printed.
I need to roll twice for initiative.
Run the notation again for a second roll - each roll is fresh and independent of the last.
The dice values look repeated.
Small samples often repeat - roll again over more attempts if you are checking fairness.
I want to keep the result.
Copy the roll out of the page before you re-roll so your log keeps the numbers you needed.
When It Works but the Output Is Poor
If the tool runs fine but the result misses, the problem is almost always the brief, not the software:
- Writing 6d2 when you meant 2d6
- Forgetting the total after reading single dice
- Rolling again before noting the result
- Mixing different sided dice in one notation
How to Stop It Happening Next Time
- Keep a saved prompt template for every task you repeat.
- Change one setting per generation so causes stay obvious.
- Run a two-minute sanity test with known input after any update.
- Note every failure and its fix; a short troubleshooting log pays for itself.
Still Stuck?
Reproduce the problem with the smallest possible input and note the exact steps that triggered it. A one-line description of what you did, what you expected and what happened is enough to get a precise answer from support or a colleague.
Frequently Asked Questions
What does NdX mean?
It is a count followed by a letter d and the number of sides - 2d6 rolls two six sided dice and totals them.
Are the rolls fair?
Each die picks a face with equal odds, so every roll is independent of the one before it.
Can I roll more than two dice?
Yes - any count works, such as 4d6, and you will see each die plus the summed total.
Is my roll history stored?
No - rolls happen in your browser and reset when the page is refreshed.
