Gomoku on Arcadia

Gomoku is “five in a row,” but strong players win through threat timing, forks, and defensive shape.

The winning idea: create threats that demand answers — then build two winning threats at once so defense becomes impossible.

How to Play

  1. Players alternate placing stones.
  2. Stones stay where placed.
  3. First to make an unbroken line of five stones wins (horizontal, vertical, or diagonal).

Core Rules

  • Turns alternate.
  • No movement after placement.
  • A line of five wins immediately.

Arcadia keeps the board clean and highlights legal placements.

Strategy: Threats & Forks

  • Prioritize open-ended lines.
  • Create double threats: two ways to win next move.
  • Defend early against opponent forks — late defense is too slow.
  • Convert advantage by forcing responses until a win appears.

Practical Tips

  • If your opponent has an open four threat, you must respond.
  • Don’t chase small threats that give away the center.
  • Play moves that improve both offense and defense.
  • When ahead, simplify by blocking their best lines first.

Opening Principles

  • Center influence usually gives the most flexibility.
  • Build shapes that can extend in multiple directions.
  • Avoid single-line commits too early — forks win games, not one-track plans.
