Chaos Engine is a backgammon engine built from scratch, currently in development. It’s designed to be embedded, not just played:

• GNU Backgammon–compatible intelligence — a clean-room port of the same specialist neural-network approach used by GNU Backgammon’s own trained nets, with no code or weights reused.
• Strong doubling-cube play — expectimax-style search backed by Monte Carlo rollouts, with doubling-cube decisions grounded in Janowski’s cube theory and full Match Equity Tables.
• Every ruleset, first-class — Backgammon, Nackgammon, Hypergammon, and Acey-Deucey are modelled as genuine engine state, not reskins of one ruleset.
• Built to embed — a Unity package and native Unreal modules, with builds shipping for Linux, Windows, macOS, iOS, and Android.
