How the result is chosen
Random seeding securely shuffles the entrants before placing them into the bracket. Empty places become byes.
Real Randomizer uses the secure random source built into modern browsers. The choice happens before any animation is shown. Visual effects make the result easy to follow, but they do not change it.
Tips for a clear and fair result
- Agree on the rules first. Choose the range, entries, filters, and repeat setting before anyone sees a result.
- Check the input. A duplicate name or missing item can change who or what has a chance to be selected.
- Run one accepted draw. Do not keep generating results only because the first answer was not popular.
- Save what matters. Copy the result or keep a simple record when the group may need to check it later.
Limits to keep in mind
Random seeding does not rank skill. Use manual seeds when past results or league rules must affect placement.
Use this page for everyday choices, lessons, games, testing, and informal draws. Elections, regulated lotteries, health choices, legal decisions, and safety-critical work need approved systems and expert review.
