Prize Wheel: Spin to Win

A prize wheel is the spin-to-win game you see at trade shows, store openings and school fairs: a visitor spins, and the slice under the pointer decides what they take home. It draws a crowd and makes even a small prize feel like a win.

This online prize wheel adds what a cardboard wheel cannot: a quantity for each prize, so it never hands out a tote bag you no longer have, and odds shown in percent next to every prize. It runs free in any browser, with no account.

1. Open the editor in list view and type your prizes, one per row.
2. Tick the Stock column and enter each quantity. Leave it empty for unlimited slices like “Spin again”.
3. Tick the Weights column to make rare prizes rarer: a weight of 0.5 gives half the chance of a weight of 1.
4. Check the percentages, then go full screen.

Each win lowers the stock by one. At zero, the prize leaves the draw and the other slices share its chance.

Many people assume the big prize on a spin-to-win wheel is never really on offer. Showing the odds is the simplest answer. Each slice here is sized exactly in proportion to its chance, and a “Custom odds” badge appears under the wheel whenever weights differ.

To plan your stock, estimate the number of spins: with 200 visitors and 20 coffees, a 10% chance makes them last all day. At a weight of 0.1, the grand prize falls to about 0.7%, roughly once every 141 spins.

Load the page once with a connection and it keeps working offline, even when the venue Wi-Fi gives up. Full screen leaves only the wheel and the Spin button and keeps the tablet awake. Stock is saved with the wheel, so a restart does not reset your counts. Display the QR code from the Share menu so visitors can check the odds on their own phone.

General information only, not legal advice: rules vary by country. Before a spin-to-win game for customers, check that you have:

• written rules covering who can play, the dates, each prize and how winners are chosen;
• a free way to take part, since many countries restrict games of chance that require a purchase;
• an age limit where needed, and a plan for handing over prizes;
• a privacy notice if you collect emails or names (GDPR in the EU, law 09-08 in Morocco).

Yes, and you can prove it. The prize is drawn by the browser’s cryptographic generator before the wheel moves, with exactly the odds displayed; how hard someone spins only changes the show, never the result. There is no option to force a winner. The wheel fairness page explains the method and simulates thousands of spins.
