What is Roulette Spinner?

The Roulette Spinner is a customizable digital lottery tool that brings fairness and visual engagement to random selection. Add any items—names, tasks, prizes, or group decisions—and let the colorful spinning wheel make the choice with transparent randomization. This tool eliminates bias that can creep into manual selection methods.

How to Use

Click "Add Item" and enter your choices into the spinner field. Customize colors for each item to improve visual variety and make results easier to identify quickly. Click the "Spin" button to rotate the wheel at rapid speed. Watch it gradually decelerate, highlighting the landing result with animation and visual feedback. Clear previous results and spin again for multiple selections, or reset the entire list to start fresh with new items. Screenshot or record outcomes for documentation.

Use Cases

The Roulette Spinner enables fair selection across many scenarios:
• Classroom management: Randomly select students for presentations or group discussions fairly
• Group decision-making: Choose restaurants, movies, or activities transparently and entertainingly
• Office and retail: Conduct transparent drawings for prizes, raffle winners, or employee recognition
• Game nights and events: Decide team assignments, game order, or reward allocation for participants

Tips & Insights

Digital randomization eliminates the human bias that subtly influences manual drawings. The animated spinning wheel creates engagement and suspense that engages viewers. For truly fair selection, all items should have equal visual allocation—this tool handles sizing automatically. The practice of using randomization for decisions traces back centuries through lotteries and ancient lot-casting traditions. Digital versions provide identical functionality without requiring physical equipment, making them perfect for remote teams and online-only events where traditional methods don't work.

Frequently Asked Questions

How many items can I add?

There is no particular limit, but we recommend a maximum of 20 items for ease of viewing the display.

Can I automatically exclude winners?

Yes, if the "Exclude Winners" option is enabled, the winning item will be automatically excluded from the next spin.

Are the lottery results fair?

Yes, each item is chosen with equal probability; it is a random selection using JavaScript's Math.random.

Can I save the roulette configuration and results for later?

Your item list and settings are saved locally on your device, so your custom roulette persists when you revisit the page. Individual spin results aren't automatically saved—take a screenshot if you need to keep a record. Your data clears if you delete your browser cache.

Can I set weighted probabilities for different items?

The basic roulette gives equal probability to all items. To simulate weighted odds, add the same item multiple times with variations (e.g., 'Option A - High', 'Option A - High', 'Option B - Low'). Each additional copy increases that item's chance of selection proportionally.

Can I customize the colors and appearance of the roulette wheel?

Yes, the tool includes color customization options for wheel segments and text. Choose from a palette or set custom colors to match your theme. Visual customization is purely aesthetic and doesn't affect selection randomness.

Can items in the roulette have duplicate names?

Yes, you can add the same name multiple times—each entry is a separate wheel segment. This increases that item's probability of being selected, which is useful for creating custom odds without a weighted system.

Is my roulette data private, or is it stored on a server?

All data stays on your device in local browser storage—nothing is sent to external servers. Your item list and selections are completely private. Data clears if you use incognito mode or delete your browser storage.

Can I share my custom roulette with other people?

There's no built-in share feature, but you can share screenshots or create a document listing your custom items for others to recreate. Some users take images of their wheel setup to share with friends and colleagues.
