Random Number Wheel 1–20

Press Spin. The wheel picks one of the 20 numbers using your browser's cryptographic random number generator, so each one is equally likely — the same odds as drawing a numbered ball from a bag.

Yes, and it should. Every spin is independent, so a repeat is normal — with 20 numbers it happens about once in 20 spins. If you want each number only once, turn on “Remove the winner after each spin” and the wheel will work through them without repeating.

Yes. Each spin draws a winner with crypto.getRandomValues(), the same random number generator browsers use for security work, and the animation is then worked backwards so the wheel lands on it. Every slice of the same size has exactly the same chance, and nothing about the spin — how hard you flick it, how long it runs — changes the odds.

Add a multiplier after the name: “Pizza x3” or “Pizza ×3” gives pizza three slices instead of one, so it wins three times as often. Repeating a name on separate lines does the same thing.

Turn on “Remove the winner after each spin”. The winner is taken off the wheel as soon as it is announced, so a run of spins deals everything out without repeats. Undo puts the last one back.

Press “Copy link” and the entries are packed into the URL. Anyone who opens it gets the same wheel, with nothing to install and no account.

The main wheel keeps your entries, your options and your recent results in your own browser, so closing the tab does not lose them. Nothing is sent to a server: the wheel, the sounds and the random draw all run on your device, and it keeps working with the wifi off.

Up to 500. Past about 60 the slices get too narrow for their labels, so the wheel hides the text and shows the winner in full when it stops.

Yes — the speaker button mutes the ticks and the fanfare, and the setting is remembered. The wheel also respects your system's “reduce motion” setting: it spins briefly and skips the confetti instead of animating for several seconds.

Both. The wheel scales to the screen, you can flick it with a finger the way you would a real wheel, and the fullscreen button blows it up for a classroom projector or a stream.
