2P Games / 2P games ++

February 2014

Introduction:

One of my entries for JS1k 2014's contest: a compilation of 4 board games for two players in 1kb.
Golfed with Subzey.
Pick a game (Tic-tac-toe, Tic-tac-toe 3D, Four in a row or Reversi), then play with mouse, turn-by-turn.
You can read a post-mortem of this game in the tech blog.
