Reading the Schedule

The official tournament schedule, game times, results, and playoff matchups can be followed through the

Official IIHS Iron Series Schedule

Playoff games are published before the Round Robin is complete, so some games will initially show placeholders instead of team names.

  • 1st Seed, 2nd Seed, 3rd Seed… — the team finishing in that Round Robin position
  • Lowest Seed / 2nd Lowest Seed — the lowest-ranked remaining team at that stage
  • Winner Semi 1 / Loser Semi 2 — determined by the result of that Semi Final

Team names will be updated as soon as the results determining each matchup are known.

In 10U, 12U, 14U and 16U, the Semi Finals are re-seeded: the 1st seed faces the lowest-ranked remaining team, and the 2nd seed faces the next-lowest. This means an upset in the Playoff round may change the Semi Final matchups.

In 18U, the Semi Final matchups are fixed at 1st vs 4th and 2nd vs 3rd.
