About Gomoku
Gomoku is quick to learn and quick to finish: on a 15×15 board Black moves first, and the first player to connect five stones in any direction wins (freestyle rules, no forbidden moves). It rewards reading shapes and blocking open threes and fours in time, and many language models that talk a good game still miss a one-move threat, which makes it a great way to compare AI players.
