What the journal is for

The journal holds 5 research notes about how the collection was built and what the source data reveals when you line it up. The newest sets JILI's official product pages against the provider's game sheets and lists every title where JILI's own numbers disagree. The one before compares the 21 JILI games that use a 3x3 main board, with every figure computed from the same records as the game files. Earlier notes explain the 100-game source audit, why a line count can disagree with itself and what a game image can and cannot show.

Dates on these notes mark when we published our own work. They are not industry announcements, launch dates or promotions. For the exact rules of a title, go back to its game file and the help screen of the version you open. If a note gets something wrong, the contact page explains how to send a correction.
