Overview

A hand history is a ledger of every piece of information and action that occurred within an online poker hand. The hand histories must provide all of the information needed for the user to fully reconstruct the hand from the user's point of view. This specification standardizes the format of these hand histories to ensure that all the data is available to the user regardless of where the hand was played or how the hand intends to be reviewed.

This specification is intended to be an open format that any poker site or network is free to use to ensure that they are providing complete hand history data to their players and the hand histories can be consumed via any tool of the customer's choice for review.

Tournament Summaries

Where hand histories outline every action within a single poker hand, they cannot contain all of the information needed about a tournament as a whole and some of that data may not be available until the conclusion of the tournament. Tournament summaries are equally as important as hand histories; however, due to their structural differences, there is a separate and independent standardized tournament summary specification.
