Tool transparency
Randomness and Fairness
A plain-language explanation of how selections work, what affects probability, and what these tools cannot decide for you.

How a wheel result is selected
The result is selected from the active entries using the site’s shared random-selection logic. The visual spin is then aligned with that result so the winner shown in the result panel matches the segment indicated by the wheel.
Animation length and visual movement do not give an entry extra weight. The list itself determines which options are eligible.
Equal chances and repeated entries
When every active item appears once, each item receives one selection opportunity. Repeating the same name or option creates additional entries and therefore increases its probability.
Before a classroom pick, raffle, or shared decision, review the list and remove accidental duplicates. Keep duplicates only when the rules intentionally allow extra chances.
Groups, pairs, and full-list randomization
Group and pair tools shuffle the supplied list before distributing entries. Group sizes are kept as even as the participant count allows. An odd number of participants necessarily leaves one unmatched person or requires one group of three, depending on the tool and the organizer’s rule.
Random distribution does not know people’s skills, accessibility needs, relationships, or other real-world constraints. Review the output whenever those factors matter.
Browser storage and privacy
Editable lists may be saved in localStorage in the current browser so they can be restored during later visits. This is device-level convenience, not an account or shared database.
Avoid entering confidential information. Use first names, initials, aliases, or ticket numbers when full personal details are unnecessary, especially on shared devices or projected screens.
When not to use randomness
Random tools are best for low-stakes choices where every listed result is already acceptable. They should not replace professional advice, safeguarding decisions, disciplinary judgment, medical or financial decisions, legal requirements, or contest rules.
Fair input preparation matters as much as the random step. Define eligibility, duplicate handling, repeat winners, and opt-out rules before running a public selection.
