Frequently Asked Questions
What happens if my participant count is not a power of 2?
The bracket generator automatically pads the participant list with BYE entries to reach the next power of 2 (e.g., 5 participants → 8 slots with 3 BYEs). BYE-matched participants advance automatically without needing a click.
Can I undo advancing the wrong participant?
Not directly in the current version — if you advance the wrong participant, click New Bracket to regenerate with the same participants and start over. A future update may add undo functionality.
What is the maximum number of participants?
The bracket supports up to 32 participants, which creates up to 5 rounds. For larger tournaments, consider running multiple sub-brackets and feeding winners into a final bracket.
Is the bracket seeding truly random?
Yes. Participants are shuffled using the Fisher-Yates algorithm before being assigned to bracket slots. Each generation produces a completely different seeding.
