Build a knockout bracket for a cricket tournament.
Builds a tournament in one of three common formats. Single Elimination lays out Round 1 matchups plus the skeleton of every following round through to the final — lose once and you're out. Round Robin schedules every participant against every other participant exactly once, split into rounds so no one plays twice in the same round, with no elimination — useful for a league-style format where final standings are based on overall record rather than a knockout path. Group Stage + Knockout splits participants into groups that each play a full round robin internally, then generates the knockout bracket skeleton for the specified number of top finishers from each group to advance into — the same format used by many real tournaments (World Cup-style group stages, for example).
For Group Stage + Knockout specifically, the knockout bracket is generated with placeholder labels (like "Winner of Group A" or "Runner-up of Group B") rather than actual names, since who actually advances depends on the group results, which this tool doesn't track. This is a structure-planning tool, not a live tracker — it shows organizers and participants the full shape of the tournament in advance, but scores and advancement are recorded by hand (or on a printed copy) as the tournament actually happens. The knockout seeding lists all group winners first, then all runners-up, run through the same standard seeding pattern as the Single Elimination format — it doesn't specifically avoid pairing two teams from the same group again in the first knockout round, which is a real simplification worth knowing about if that matters for your event.
If your participant count isn't a power of 2 (like 6, or 11) for Single Elimination — or your group-advancer count isn't, for Group Stage + Knockout — the bracket automatically expands to the next power of 2 (8, or 16) and fills the extra slots with byes — a bye means that participant automatically advances without playing that round, exactly like a real tournament bracket handles an uneven number of entrants. Byes are assigned using the same standard seeding pattern real tournaments use, so they land on the participants seeded highest (earliest in your list or group placement) rather than arbitrarily.
With "Randomize the order" on (the default), your list is shuffled before bracket or group positions are assigned, so there's no advantage tied to the order you happened to type names in. Turn it off if your list is already in a deliberate seed order (strongest to weakest) and you want that exact order to determine seeding — for Single Elimination, that means the standard seeding pattern (1 vs 8, 4 vs 5, and so on) keeps top seeds apart for as long as possible; for Group Stage, it means group assignment follows a "snake" order so the strongest entrants are spread evenly rather than clustered into one group.
Single Elimination is the classic knockout bracket. Round Robin fits a league-style event where everyone should play everyone at least once. Group Stage + Knockout suits a bigger event — it narrows a large field down through groups before a final knockout push, the same shape as a World Cup.
A bye happens when the number of participants (or knockout-stage entries, for Group Stage + Knockout) isn’t a power of 2 (8, 16, 32...) — the bracket still needs to be that size, so the extra empty slots are filled with byes, and whoever is matched against a bye automatically advances without playing that round.
The highest seeds (earliest in your list, if randomizing is off) — the same convention real tournaments use, so the strongest entrants get the least disruptive path through the bracket.
With it on, your list is shuffled before bracket or group positions are assigned, so nobody has an advantage from list order. With it off, your list order is treated as seed order (first = strongest) — for Single Elimination that keeps top seeds apart via the standard seeding pattern; for Group Stage it spreads seeds across groups using a snake-draft order rather than clustering the strongest entrants into one group.
Yes, possibly — the knockout seeding lists all group winners first and all runners-up after, run through the standard seeding pattern, but it doesn’t specifically check for and avoid an immediate same-group rematch. Worth knowing if that matters for your event.
No — this generates the initial structure only (bracket, schedule, or both). Recording results and advancing winners is done by hand (or on a printed copy), not tracked live by this tool.
