Step-by-step instructions
Confirm the entrants
List one player or team per line. Verify the roster before assigning bracket positions.
Generate the opening round
Select Build bracket. The tool draws random positions and inserts byes when the field does not fill a power-of-two bracket.
Save and track the competition
Copy the bracket and record winners in your own event sheet. The later-round entries are progression placeholders, not live scores.
Worked example
Eight entrants fill an eight-place bracket. Everyone starts in the opening round without a bye.
One valid result is shown below. Your generated outcome will vary.
Example input
Alex Jamie Morgan Taylor Sam Jordan Casey Riley
Example result
Round 1 1. Jordan vs Jamie 2. Sam vs Casey 3. Riley vs Alex 4. Taylor vs Morgan Round 2 1. Winner of match 1 vs winner of match 2 2. Winner of match 3 vs winner of match 4 Final 1. Winner of previous-round match 1 vs winner of previous-round match 2
The bracket shows four opening matchups followed by winner placeholders. It is not a live competition-management system.
Decide the tournament format before drawing
Single elimination removes an entrant after a loss. If your event needs round robin, double elimination, or group stages, this output does not model that format. Confirm entrant labels and any ranking requirements before generating, then save one final bracket and track results separately. Do not redraw a bracket after play begins.
Settings and limits to check
The example has 8 retained entries. The generator supports 2–128 entrants and creates a single-elimination layout. Bracket capacity is the next power of two, and empty places become first-round byes. Later rounds show winner placeholders. It does not seed by ranking, protect top teams, manage round-robin play, or update results automatically.
Settings used in this example
Remove duplicate entries: On
Keep a usable copy of the result
Use Copy to place the current result in your own notes, or Download to keep a text file. Keep the eligible input list with the result when you need to explain which entries took part. A new generation replaces the displayed result rather than adding to a saved history.
The tool runs in your browser and does not upload your input. Save the result before refreshing or leaving the page. If other people need to use the same outcome, share your saved copy rather than asking them to generate another independent result.
Frequently asked questions
How many played matches complete an eight-entrant single-elimination event?
Seven, assuming every elimination is decided by one match and there are no additional placement games.
Is random seeding the same as ranking players?
No. Random seeding assigns positions by chance. Skill-based seeding needs a separate ranking process.
Does the bracket update when someone wins?
No. Save the output and track match results yourself. Later rounds are placeholders showing progression.
What should I check in the worked example?
The bracket shows four opening matchups followed by winner placeholders. It is not a live competition-management system.
