The Ruleta de Nombres Aleatorios is a free, fast random wheel spinner built for rapid, transparent decision-making without bias or guesswork. Powered by browser-native cryptographic entropy, it provides an impartial draw with smooth 60fps physics, customizable slice weights, and optional winner elimination mode for multi-round sessions. Whether you are running a giveaway, organizing classroom participation, or making an everyday choice, the wheel operates 100% client-side with complete privacy.
How the Ruleta de Nombres Aleatorios Settles name and roster draws
The Ruleta de Nombres Aleatorios exists for one specific failure mode: the same confident people getting picked while quieter ones never do. It loads with 10 ready-made entries (Sofía, Mateo, Valentina, Santiago, 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. Soporte para pegado masivo: Pega cientos de nombres al instante desde Excel o procesadores de texto and modo eliminación de ganadores: Elimina automáticamente o manualmente los nombres elegidos para que nadie se repita are both available while the wheel is live.
Typical use looks like this: Participación escolar y elección de estudiantes en el aula sin favoritismo. 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
