Tool Introduction

Gomoku, also known as Five in a Row or Gobang, is a classic abstract strategy game from East Asia. Challenge the built-in computer at three difficulty levels, or play a hot-seat match against a friend on the same device.

The computer evaluates every candidate move by scoring attack and defense lines, blocks your threats and hunts for its own winning lines - Hard mode is genuinely tricky to beat.
