The list isn't deduplicated — every line is treated as one entry in the drawing pool, duplicates included. With the default six unique names, each has an equal 1-in-6 chance (about 16.7%). Add a seventh line repeating one of those names, and the pool becomes seven entries where that name now fills two of them: about 28.6% for the repeated name versus 14.3% for everyone else. That's not a bug to work around — it's a legitimate way to run a deliberately weighted drawing, like giving someone extra raffle tickets, just by listing their name multiple times.
Because the pool is built directly from lines of text, two entries that look identical but differ in trailing spaces or capitalization are still counted as separate, distinct pool entries rather than being merged — which matters if a list was pasted from somewhere else and might contain accidental near-duplicates. It's worth a quick scan of the list before pulling the lever if the exact odds matter, since what looks like one name typed twice by mistake will function exactly like a deliberate double entry.
Just like the other randomizers, the winner is picked using your browser's random number generator before the reel even starts spinning — the spinning animation is just for show.
It's built to spin for about 13 seconds before landing, giving the moment some real suspense rather than resolving instantly — similar to how a real slot machine's reel takes a few seconds to settle.
Yes — list your entries one per line and pull the lever. Just keep in mind this uses your browser's standard random number generator, which is fine for casual draws but not intended for regulated or high-stakes drawings.
