Frequently Asked Questions

How does the Random Decision Picker ensure every option has an equal chance?

Instead of using standard Math.random(), the tool uses the browser's Web Crypto API (crypto.getRandomValues) with rejection sampling and the Fisher-Yates (Knuth) shuffle algorithm. Every possible permutation of your N choices has an exact 1/N! probability.

Can I enter options separated by commas instead of new lines?

Yes. If you paste a single line containing commas or semicolons (such as 'Option A, Option B, Option C'), the parser automatically splits them into individual choices.

What happens if my list contains duplicate entries?

By default, duplicate lines act as weighted tickets (giving repeated entries a proportionally higher chance of selection). Enable 'Remove Duplicate Options Before Drawing' to deduplicate your list so every unique choice has an equal probability.

Can I rank all of my options from first to last?

Yes. Even when you pick 1 winner, the output displays both the selected top winner(s) and the complete randomized ranking of all remaining options.

Are my personal choices or team names sent to a server?

No. All list parsing and cryptographic shuffling run 100% locally in your browser memory.
