Lot Numbers - Round Robin Tournaments

In round robin tournaments, lot numbers determine color assignments throughout the event. SwissSys offers three options for how lot numbers are assigned, configured in Setup → Rules for pairing.

Lot Number Options

This is a radio group with three choices:

  • By rating (default) — Lot numbers are assigned in rating order. The highest-rated player receives lot number 1, the second-highest receives lot number 2, and so on.
  • Random — SwissSys assigns lot numbers at random when pairings are first generated.
  • Manual — SwissSys prompts you to enter the lot numbers when you generate pairings at the start of the round robin. This lets you enter numbers that were drawn physically during the opening ceremony.

Once lot numbers are assigned and pairings generated, they cannot be changed without clearing the round and re-pairing.
