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.
Worked example and limits
Try Alice, Bob, Bob on separate lines. If each line is an entry, Bob has two positions; the chance is not equal per unique name. Remove unintended duplicates and empty lines before the real draw, agree whether winners are removed, and show participants the rule in advance. Do not redraw merely because a result is unwelcome. Browser randomness is not an independently auditable lottery or legal draw certificate.
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.
