A real reference, not a list
Every entry states the result, how strongly it was solved, the search-space size, who solved it and when, and the citations — generated from structured data, so the catalog and these pages never drift.
Solved Games
The reference for which games are solved — by whom, how strongly, and what’s left. Maintained by someone who actually solves them: the catalog is backed by an open-source retrograde engine that has produced first-published strong solutions (six men’s morris; Y through side 6), with playable perfect-play explorers that solve in your browser.

The engineThe generic open-source retrograde solver behind the catalog and the explorers.
What makes it different
Section titled “What makes it different”Backed by an engine
A generic retrograde-analysis solver that has produced first-published strong solutions, not just a curated list — with explorers you can play.
The open frontier
Not just what’s solved, but what isn’t — the next targets, what each would cost in time and space, and the methods proposed. A living research agenda.
