Gomoku, also known as Five in a Row or Gobang, is an elegant strategy game played on a grid similar to a Go board. Two players take turns placing black and white stones, and the first to form an unbroken line of exactly five stones horizontally, vertically, or diagonally wins. Though the rules take seconds to learn, the strategy runs deep: experienced players build overlapping threats, force responses, and read several moves ahead. This version offers three AI difficulty levels, so beginners can enjoy casual matches while seasoned players face a genuinely challenging opponent. Games typically last five to fifteen minutes, making Gomoku a perfect balance of quick play and meaningful strategy.
