Hex Reversi

Hex Reversi is an extensible Reversi/Othello implementation on a hexagonal grid. The core emphasis is software design: clean MVC separation, adapters for different play modes, and modular AI strategies that can be mixed and matched.

Cube-coordinate hex board (q+r+s=0) with odd-r offset conversion and configurable side length

TryTwo combinator chains strategies (corners → avoid-near-corners → minimax → capture-max) with fallible/infallible pattern

Four adapter classes bridge third-party provider code without modifying core—ReadOnly model, view, input, and strategy adapters

What I built

  • Hex-grid Reversi engine with configurable board shapes and starting states
  • MVC architecture with GUI + text views and a controller layer
  • Strategy system including minimax and composable heuristics

How it works

  1. 1Represent the board on an odd-r hex coordinate system
  2. 2Validate moves and apply flips according to Reversi rules
  3. 3Run players (human/AI) through a controller loop
  4. 4Plug different strategies into the AI player

Next steps

  • Add stronger evaluation heuristics and time controls
  • Improve UI polish and strategy visualization
