Options
One per line - names, prizes, anything.
A short pause, then a fair draw.
For drawing several without repeats.
Yes. Every option has an exactly equal chance, drawn from the browser's cryptographic generator with rejection sampling so there is no bias toward the start of the list.
Yes - turn on 'remove the winner' and run repeated draws to pick several people without repeats.
As many as you like, one per line. Paste a whole list straight in.
No. It lives in the page while it is open and is never sent anywhere.
Paste a list of options and draw a winner fairly. Every entry has an exactly equal chance, because the draw uses the browser's cryptographic generator with rejection sampling - a plain modulo of a random number subtly favours the start of a list, which is the kind of bias nobody notices and everybody would object to. Turn on the remove-winner option to draw several in a row without repeats, which is what raffles and classroom selection usually need.
