How We Handle Uneven Teams (BYEs)
A mathematically perfect single-elimination tournament requires the number of participants to be a power of two (4, 8, 16, 32, 64) to ensure symmetric matchups.
If you input an odd or non-symmetric number of teams (e.g., 11 teams), our smart algorithmic engine automatically identifies the next highest power of two and injects "BYEs" into the first round. A BYE signifies that a randomly seeded team automatically skips the preliminary round and advances directly to Round 2, ensuring the bracket math aligns perfectly for the remainder of the tournament.
Frequently Asked Questions (FAQ)
Is there a maximum limit to how many teams I can enter?
The core JavaScript engine can process thousands of entries in milliseconds. However, for visual readability on standard desktop monitors and mobile devices, we recommend keeping tournaments under 128 teams. The interface utilizes horizontal scrolling to accommodate massive brackets without breaking your screen layout.
Is my team data sent to external servers?
Absolutely not. We prioritize your privacy. 100% of the tournament generation, shuffling logic, and user interactions happen client-side directly within your web browser. Nothing is ever uploaded or logged in a database.
How do I correct a typo after generating the bracket?
If you notice a mistake or need to swap a participant, simply update the original list in the input box and click "Generate Bracket" again to render a fresh, updated tree.
