Frequently Asked Questions (FAQ)

Answers to common questions about using SpinWheelKing as your go-to random choice generator.

Is SpinWheelKing a free online random wheel spinner without sign up?↓

Yes. SpinWheelKing is a 100% free online random wheel spinner and decision picker wheel. No registration, user accounts, software downloads, or hidden paywalls are required. You can spin infinitely, customize entries, save custom lists locally, and generate shareable links for free.

How does the Wheel of Names pick fair giveaway and raffle winners?↓

To conduct a giveaway or prize raffle draw, paste your entry list into the options box (one name per line or bulk copy-paste from Excel/CSV) and press SPIN. Once a winner is chosen, click "Remove Winner" so subsequent spins select remaining entrants fairly without duplicate picks.

How cryptographically fair and unbiased is the decision picker wheel?↓

Every spin draws hardware-level entropy from the browser Web Cryptography API (crypto.getRandomValues), rather than standard pseudo-random Math.random() seeds. This guarantees that every slice receives an exact, mathematically uniform probability with zero bias.

Can I use the random student name picker on classroom smartboards?↓

Yes! Educators worldwide use our random student name picker wheel for cold calling, student participation, and presentation order. SpinWheelKing includes Fullscreen Theater Mode (press F or click Fullscreen), rich sound effects, smooth 60fps deceleration physics, and celebratory confetti designed for smartboards, Zoom, and live streams.

How does the random team generator split names into balanced teams?↓

The random team generator wheel uses a cryptographically seeded Fisher-Yates shuffle pass to split your participant list into equal teams or custom group sizes instantly. Remainder entrants are distributed evenly across teams so no one is picked last.

How do I make a 50/50 decision with the Yes or No Wheel?↓

Load the Yes or No Wheel for instant binary decision making. Each slice occupies an equal 180-degree canvas arc. You can also add a third "Maybe" slice or configure custom weighted probabilities to nudge odds while keeping slice widths transparent.

Are custom name lists stored securely on local device storage?↓

Yes. SpinWheelKing executes 100% client-side inside your web browser. Your entry lists, custom color palettes, saved wheels, and spin history remain strictly stored in your local browser storage and are never uploaded or transmitted to external servers.

Can I set custom weights or slice probabilities on a random wheel?↓

Yes. Toggle Weighted Mode in the Customize panel to assign numerical weights to individual slices, making specific options proportionally more or less likely to be selected according to your custom rules.

Does SpinWheelKing work offline without an active internet connection?↓

Yes. Once the web application loads, all wheel mechanics, 60fps physics engine rendering, audio synthesizers, and local storage run fully offline without requiring an active internet connection.
