Fractal Go

Real-time multiplayer Go board game

repo

My first real project at Fractal Bootcamp - a multiplayer Go board game with real-time sync.

what i built

A full-stack Go game where two players can connect and play against each other with the board syncing in real-time via WebSockets.

the hard parts

  • learning the rules - I didn't know how to play Go when I started. The rules are deceptively simple but the implementation is not.
  • capture logic - detecting when stones are captured requires flood-fill algorithms to find connected groups and check for liberties.
  • ko rule - preventing infinite loops by disallowing moves that recreate the previous board state.
  • territory scoring - counting surrounded empty spaces at the end of the game.

what i learned

The biggest lesson: don't try to hold the whole thing in your head. Break it down step by step. Figure out the next piece of data you need, get it, repeat.
