How to Use a Random Wheel for a Fair Draw
A fair draw requires removing accidental duplicates, publishing rules and weights in advance and recording results. A web wheel is not legal certification.
What to know before you start
Animation does not create randomness; the selected result should come from the browser random generator. A web wheel is not a substitute for legally regulated drawing procedures.
Recommended workflow
- Publish the entry list and rules before the first spin.
- Remove accidental duplicates unless duplicate entries are intentionally being used as weights.
- Record winners and apply the same repeat/removal rule to every spin.
How to check the result
Recheck the result against the original input and the rule you intended to apply. Animation does not create randomness; the selected result should come from the browser random generator. A web wheel is not a substitute for legally regulated drawing procedures.
Common mistakes
Common failures come from wrong units, ambiguous assumptions, changing the rule after seeing a result, or using a quick browser workflow where a regulated or specialist process is required.
Frequently asked questions
Is the wheel fair?
Each equal entry should receive the same selection chance when no weighting or duplication is used. Review the list before the draw.
Can I stop the same name winning twice?
Enable removal after selection so the chosen entry is taken off the wheel for subsequent spins.
