Turn
Universal turn-based game engine with declarative rules
What it does
Turn is a generic engine for turn-based games. Each game is expressed as declarative rules (legal moves per state, win/draw conditions, scoring) rather than handwritten game logic. Players are pluggable: a single match can mix random, heuristic, AI-policy, and GTO-solver bots — useful for testing both rule designs and AI strategies.
Built-in metrics
- Luck factor — how much variance in outcome comes from randomness vs decisions.
- Balance — how often each starting position wins under matched players.
- Duration — distribution of game length.
These run automatically across thousands of self-play games whenever a rule changes, so designers can see what their tweak actually did.
Why a generic engine
A single engine means new games (Flipping Poker, future board-game prototypes, Ark Nova analysis) all share the same bots, metrics, and tournament harness. Add a rule file, get analysis for free.
Status
In dev. Engine + base bot types live; rule files for Flipping Poker and a small set of test games exist.
