Random Picker Wheel

When you need to pick someone or something at random and want it to feel fair and fun, a spinning wheel beats a coin flip. Paste your list, hit spin, and watch the wheel decelerate to a winner — complete with a confetti burst when it stops.

Each line you enter becomes a slice, automatically assigned a distinct color so the wheel stays readable even with a dozen entries. The spin uses real animation physics: an initial velocity that decays through friction frame by frame via requestAnimationFrame, so it slows down naturally rather than snapping to a result. The winner is read from the slice under the pointer when the wheel stops, so what you see is what you get.

Teachers calling on students, streamers running giveaways, and groups deciding where to eat all use it the same way. An optional setting removes each winner after the spin, which is exactly what you want for drawing multiple raffle winners without repeats.

Entries are laid out as equal segments around a wheel, which is spun with a randomised initial velocity and then slowed by a friction factor applied each frame until it stops. The segment under the pointer when motion ends is the result.

The physical simulation is presentation rather than mechanism — the outcome is determined by the random starting velocity, and the deceleration simply makes arriving at it feel like a draw rather than a calculation. That matters for how a result is received: watching a wheel slow down is far more convincing to a group than a name appearing instantly.

Because segments are equal, every entry has the same probability. Adding an entry changes everyone's odds equally.

Randomness here comes from the browser's ordinary pseudorandom generator, which is uniform and perfectly adequate for choosing who presents first, which restaurant to try, or which name gets the spare ticket. It is not cryptographically unpredictable, so it is unsuitable for anything where a participant has a real incentive to game the outcome — a regulated prize draw needs a verifiable process, usually a published seed or a third-party audit.

The other reason to be careful with high-stakes draws is that nobody watching can verify anything. A wheel is a visual performance, and its persuasiveness is exactly why it should not be the mechanism for something contested. For genuine transparency, draw from a publicly agreed source of randomness that participants can check afterwards.

One behavioural note. Independent spins mean a name can come up twice in a row, and people reliably read that as the wheel being broken — the gambler's fallacy in miniature. If you need each entry drawn once, remove it after it wins rather than expecting the randomness to avoid repeats.
