Comprehensive Guide

How the Roleta de Nomes Aleatórios Settles name and roster draws

The Roleta de Nomes Aleatórios exists for one specific failure mode: the same confident people getting picked while quieter ones never do. It loads with 10 ready-made entries (Lucas, Gabriel, Mateus, Ana, and more) so you can spin within a couple of seconds, then swap in your own list when the defaults do not match your situation.

What you get out of it is visible, provable fairness that nobody in the room can dispute. The stopping angle comes from window.crypto.getRandomValues() rather than Math.random(), and each slice occupies an arc exactly proportional to its weight — so the visual you see on the canvas is a literal picture of the odds. Importação em lote: cole centenas de nomes de planilhas Excel ou documentos de texto and modo eliminação de ganhador: remova automaticamente a pessoa sorteada para não repetir are both available while the wheel is live.

Typical use looks like this: Sorteio de alunos para apresentação de trabalhos ou leitura em sala de aula. Teachers, team leads, event hosts tend to reach for it most, usually because the alternative — names in a hat or scrolling a spreadsheet — either takes longer or invites argument. Recommended setup: Remove Winner enabled so each name comes up at most once per round.

Why Our Random Wheel Is Cryptographically Fair

True Entropy
Hardware-level system entropy guarantees zero statistical clustering or cycle predictability.
Proportional Physics
Exact segment angle calculations guarantee 100% accurate slice probabilities matching option weights.
100% Local Privacy
Your participant lists, student names, and private choices never leave your browser or get sent to remote servers.

Expert Tips & Tricks

Tips for Getting the Best Experience

Replace the defaults before you rely on the result

The starting entries (Lucas, Gabriel, Mateus, Ana…) are examples. Paste your real list — one item per line, bulk paste from a spreadsheet works — so the odds reflect your actual options.

Send the wheel instead of describing it

The Share button encodes the title, entries, and settings into the URL. Recipients open your exact wheel; nothing is stored on a server.

Use fullscreen for anything with an audience

On a projector, TV, or shared screen, fullscreen mode enlarges the canvas and pointer so the roleta de nomes aleatórios result is legible from the back of the room.

Keyboard Spacebar Shortcut

Press the Spacebar on any computer keyboard to trigger spins instantly without using a mouse.
