Bracket challenge

A bracket challenge is a free prediction game on a knockout draw.

Everyone fills in the same tournament bracket before it starts, and points follow the real results. Fanzava runs yours under your own brand: our team builds the bracket and records every result. Looking for an official draw instead? The links are just below.

Free to start. No credit card.

The GAA championships

A GAA championship bracket: what you can and cannot run.

Both championships end in a knockout people call a bracket. Neither is a simple knockout tree from the start, and that decides what you can run.

Football: the qualifier series.

From 2026 the Sam Maguire is a 16-county qualifier series. Round 1 pairs the eight provincial finalists with the eight other qualifiers. Round 2A splits the winners, Round 2B the losers, and Round 3 puts the 2A losers against the 2B winners. Eight counties reach the quarter-finals.

Hurling: the round robins.

Munster and Leinster are played as round robins. The top two in each province meet in the provincial final, and third place goes straight into the All-Ireland quarter-finals. A table is not a bracket.

Why the whole championship is not one bracket.

A county beaten in Round 1 drops into Round 2B instead of going out, and a bracket only follows winners forward. Fanzava brackets are single elimination, so the full championship cannot be one of them.

What to run instead.

Run predictions on each round as the fixtures are set. Once the quarter-finals are set and the route to the final is known, the last eight counties are a true knockout: seven matches to the final. Our team can build that as a bracket, locked before the quarter-finals.

The arithmetic of a knockout bracket.

Matches
Field size minus one. Every entrant but the winner loses exactly once, so 64 teams is always 63 matches.
Sizes Fanzava runs
4, 8, 16, 32, 64 or 128 teams, with no byes. Play-in games can fill the last slots and are settled before the bracket locks.
Scoring
One point times the round number for each correct pick, plus 10 for the right champion. It is the same for every bracket.
Brackets each
One by default, or up to five if you allow it. A person's best bracket ranks on the leaderboard.

How a bracket challenge runs.

  1. The tree is published, and our team builds it.

    Seeds, first-round pairings and the shape of the draw go up at once. Everyone picks every match through to the final in one sitting, rather than being chased week after week.

  2. Picks lock together.

    One deadline, usually minutes before the first match. Nobody sees anyone else's picks before then, so there is nothing to copy. After lock, pick percentages show how the field split.

  3. Results are recorded, and every bracket rescores.

    Each result is recorded as its match is decided: from Fanzava's results feed where it carries the match, and by our team where it does not. Correct later-round picks are worth more, so a bracket that looks dead after one upset can still win.

Decisions that shape a bracket challenge.

A bracket has one deadline and almost no admin. What it has instead is scoring design.

Single elimination, always.

Double elimination gives every entrant a second life but doubles the matches and produces a tree most people cannot read at a glance. For predictions, single elimination is almost always right, and it is the only kind Fanzava runs.

Linear weighting, not doubling.

Fanzava scores one point in round one, two in round two and so on, with ten more for the champion. Doubling weights make every round worth the same in total. Linear keeps the opening round meaningful and lets the champion pick swing the contest.

No upset bonus.

Some competitions pay extra for correctly picking a lower seed. Fanzava does not: points follow the round, not the seed, and the weighting is not set per competition.

Questions bracket challenge organisers ask.

What is a bracket challenge?
A free prediction game on a knockout tournament. Everyone picks the winner of every match before it starts, points follow the real results, and a leaderboard ranks the brackets. Fanzava runs one under your own brand, so it is your challenge and not ours.
What if our field is not a power of two?
Fanzava brackets run 4, 8, 16, 32, 64 or 128 teams with no byes. A field in between uses play-in games to fill the last slots, settled before the bracket locks. Picks on a slot a play-in changes are cleared and people are told.
Can we run the All-Ireland championship as a bracket?
Not the whole championship. The football qualifier series gives a beaten county a second chance, and the hurling provinces are round robins, while Fanzava brackets only follow winners forward. Run predictions on the earlier rounds, then ask our team for an eight-county bracket once the quarter-finals are set.
Who enters the results?
You do not. Each result is recorded from Fanzava's results feed where it carries the match, and by our team where it does not. Two-legged ties are recorded by our team once decided.
Can I print a bracket?
Yes. The free bracket maker prints a clean blank bracket for any field from 2 to 128 names, with byes handled and no signup.
What does it cost?
Brackets are not on the Free plan. Run one on Starter or above, or buy a one-off Bracket Pass for a single event. The prices are in the Bracket Pass panel on this page.
Does money change hands?
No. Entry is free and Fanzava never handles entry money. It is a free social game where people make predictions and a leaderboard ranks them.
