Rule 9 · HPA Blue Book 2026
Unfinished game
A game is played to the end unless stopped for an unavoidable reason, and then it resumes exactly where it stopped.
UNFINISHED GAME. Before the game has started, or once the game has started, it shall be played to a finish unless stopped by the umpire or the host Tournament Committee, having consulted the team captains and match officials, for some unavoidable cause. It shall be resumed at the point at which it has stopped as to score, chukka and position of the ball at the earliest convenient time, to be decided upon by the host Tournament Committee. See also Part 2, Annex D, point 16 for recalculating the score if the game could not be completed.
