Unified Resolution Criteria (Consistent across platforms)

All platforms use the same core resolution logic based on official Grand Slam statistics, with consistent handling of incomplete matches, cancellations, and tiebreak counting.Primary resolution logic: Official Grand Slam statistics

Core resolution logic:

  • Match must be completed to determine outcomes; otherwise, 50-50 resolution applies
  • Tiebreak games count as one game toward totals
  • Markets resolve based on the minimum number of additional games required to guarantee an outcome if play stops early

Edge cases & clarifications:

  • Match not completed: Resolves to 50-50 unless outcome is already unconditionally determined based on completed play
  • Cancellation before play: Resolves to 50-50 for all markets
  • Walkover/retirement: Resolves to 50-50 unless the outcome was already determined by completed play
