Frequently asked questions
Are the results random?
Yes. Each roll picks new random faces for every die, and all calculations happen only in your browser.
How many and what dice can I roll?
You can roll from 1 to 8 at a time, and choose from 4, 6, 8, 10, 12, and 20 sides.
Does it show the total?
Yes. When you roll several, it shows each die's face along with the overall total.
Practical example and verification criteria
Dice Roller: First define the draw population—such as a candidate list, numeric range, or number of dice—and check whitespace, duplicates, and whether minimum and maximum values are inclusive. Before running it, agree whether repeated winners are allowed, whether selected entries are removed, and when a redraw occurs so rules do not change to fit the result.
Dice Roller: For a quick check, start with 2d6 → 2..12 as a small input whose result relationship you can verify directly. Confirm that the input summary, units, and options match your intent before applying the tool to real values or a copy of the source; this reduces setup mistakes.
Dice Roller: Record the input list and options, then verify that the result is among the candidates or within the range and that nothing is missing or duplicated. Different results under identical conditions are normal. Browser randomness is for casual choices; regulated prizes, lottery prediction, cryptographic keys, or auditable drawings require local-rule compliance and a validated purpose-built system.
Dice Roller · Work record: For real work, record the input conditions, selected options, and result together. Do not assume the same state will remain after a refresh or device change. Preserve important results separately using copy, download, a screenshot, or another method the page supports, then reopen them in the target environment.
Dice Roller · Error check: If an error or unexpected result appears, reduce the input, run again with default options, and then change one condition at a time. Recording error messages and boundary values helps distinguish format issues, unsupported cases, and browser resource limits, and prevents an empty result from being mistaken for success.
Dice Roller · Scope of use: Check the page guidance for browser processing versus server lookup, storage location, and supported scope. Use sensitive source material or secrets only when strictly necessary. High-impact work such as legal, financial, or medical decisions or changes to an operational system requires current authoritative information and a separate verification process.
