Randomness and fairness

How ClickTheWheel randomness works

ClickTheWheel is a browser-based random picker. It helps choose one visible result from the entries you provide, but the quality of the result depends on the list, duplicate rules, and setup decisions made before the wheel moves.

The list defines the odds

A wheel can only choose from the entries on it. If a name appears twice, it can be selected through either slice. If an option is missing, the wheel cannot select it.

Random selection is not the same as fair setup

The spin can be random while the setup is unfair. Fairness comes from clean entries, clear eligibility, duplicate rules, and a result rule that everyone understands before the spin.

Visible process builds trust

For classrooms, raffles, meetings, and public draws, show the list before spinning and keep the selected result visible long enough for people to read it.

What changes the chance of being selected?

In a simple wheel, each visible entry slice is one opportunity to be selected. If every eligible person appears once, each person has the same starting chance. If someone appears three times, they have three entries. That may be correct for bonus-entry contests, but it should be intentional and written in the rules.

One entry each

Maria, Jules, Sam, and Tina each appear once. This is the clearest setup for one-person-one-chance drawings.

Weighted entries

Maria appears three times because the rules allow bonus entries. This can be fair only if the rule is published before the draw.

Real examples

Teacher with 32 students

List: 32 student labels, one per line
Rule: Remove selected students until everyone has had a chance.
Note: Use initials, first names, or group labels if the screen is public.

Instagram giveaway with 480 comments

List: 480 cleaned eligible usernames after removing invalid entries
Rule: One username can win once unless the published rules allow repeat wins.
Note: Keep the export, cleaned list count, winner modal, and result history.

Office raffle with 3 prize tiers

List: Eligible employee IDs or ticket numbers
Rule: Draw first prize first, remove the winner, then draw the next tier.
Note: Announce prize order before the first spin.

Family chore wheel for 5 people

List: Five names or five chores, depending on the assignment method
Rule: Remove each assigned chore so every chore is used once.
Note: Do not include chores that are not actually due this week.

What result history can and cannot prove

Result history helps show what happened after the spin. It is useful for multiple winners, classroom turns, presentation order, and prize tiers. It does not prove that the original entry list was complete or that every participant was eligible. That proof comes from the preparation around the wheel.

When not to use a random wheel

Medical, legal, hiring, discipline, safety, or emergency decisions.
Prize drawings where the published rules require a different selection method.
Situations where entries are incomplete, private, or not yet verified.
Any decision where a random result would hide responsibility instead of helping the group choose.
