Lucky Draw Wheel

Run Fair Lucky Draws with Excel Import, Participant Photos & Automatic Winner Removal

Lucky Draw Wheel is a complete event prize roulette built for company Dinner & Dance (D&D) events, classroom raffles, and livestream giveaways. Import hundreds of names from Excel or CSV, upload participant photos directly onto the wheel slices, define your prize tiers and quantities, choose which prize to spin for, and automatically remove each winner after they win.

Step-by-Step Instructions: How to Use Lucky Draw Wheel

1. Add your prizes and quantities in the Prize Manager (e.g., Grand Prize ×1, 2nd Prize ×2) and click the prize you want to roll for first.
2. Add participants by pasting from Excel, importing a CSV file, or uploading participant photos.
3. Click "Spin" — the winner is announced with fanfare, their prize count is updated, and their name is automatically removed before the next spin.

Practical Use Cases & Applications

Frequently Asked Questions (Lucky Draw Wheel)

Does the Lucky Draw Wheel remove winners so they cannot win twice?

Yes. By default, the "Automatically remove winner from wheel after being picked" option is enabled, so once a person wins a prize, their name and photo are removed from the pool for subsequent spins.

Can I upload participant photos instead of just names?

Yes! Click "Upload Participant Photos" to select multiple photos at once, or click the camera icon next to any participant’s name to display their photo right on the spinning wheel and winner banner.
