New Repository Offers Formalization of Combinatorial Games in Lean

A GitHub repository introduces combinatorial games in the Lean proof assistant. The project contains formal definitions and theorems. It enables mathematicians to verify game properties mechanically. The codebase includes examples of classic impartial games. Developers can extend the library for custom game analysis. The work bridges game theory and formal verification. It is open‑source and invites community contributions. Documentation guides users through setup and usage.
