Event & Classroom Best Practices

Without Replacement01

Enable 'Remove Winner' for Raffles

In Settings, toggle 'Remove winner automatically'. As each winning ticket or student number is called, its slice is cleanly removed from subsequent spins, guaranteeing zero repeat winners.

Presentation Mode02

Project in Full-Screen Mode

Click the fullscreen icon (or press 'F') to project the wheel onto smartboards, classroom projectors, or Twitch/YouTube streams without UI clutter or browser bars.

Quick Presets03

1-Click Range Switching

Use the quick preset chips below the wheel to swap between 1–6 (Dice), 1–10, 1–20, 1–50, or 1–100 ranges instantly without re-typing numbers.

Zero-Modulo Cryptographic Randomness

CSPRNG Uniformity

Engineered with crypto.getRandomValues to guarantee an exactly uniform discrete distribution across all integers in the range, free from pseudo-random seed repeats.

Preguntas Frecuentes (FAQ)

Can I generate non-consecutive numbers (e.g. raffle ticket serials)?

Yes. Click the Text tab in the Entries panel and paste your exact list of ticket numbers (e.g. #1024, #1089, #2401) separated by newlines.

How many numbers can the wheel support comfortably?

The HTML5 canvas comfortably renders up to 500+ numbered slices with dynamic font scaling and auto-collapsing slice labels to ensure smooth 60fps spinning.

Does it prevent teachers or streamers from secretly rigging outcomes?

Yes. Spins execute client-side using cryptographic browser APIs with zero hidden weighting unless manually configured in the visible Entries panel.
