About the game
Gomoku, or Five-in-a-Row, is played on a Go board where two players alternately place stones, trying to line up five of their color horizontally, vertically, or diagonally.
How to play
Click an intersection to place your stone. The first player to connect five in a row wins. Watch both your offense and your opponent's threats.
Tips & strategy
['Build open-ended lines (both ends free) for unstoppable threats.', "Always check for your opponent's four-in-a-row.", 'Control the center early for maximum reach.']
Advanced guide
Gomoku rewards both attack and vigilance. Strive to make lines with two open ends so a single move can create a double threat. Equally, never ignore your opponent's emerging line - a single missed block turns into an unstoppable open four on their next turn.
History & origins
Gomoku originated in East Asia centuries ago and is now played competitively worldwide.
