The rules

How wall go works

Wall Go (벽바둑) is a 2 to 4 player territory game on a 7×7 board, the game from The Devil's Plan. Here is the full ruleset.

Objective

Move your stones and build walls to enclose territory: areas containing only your stones. The player with the most territory wins.

Setup

  • The board is 7x7 with 2 to 4 players
  • Each player starts with stones in fixed corner positions
  • Additional stones are placed in a snake draft (1-2-2-1) to balance the advantage of placing first
  • After placement, the player who did not place last moves first

Each turn

  1. Select one of your stones
  2. Move 0, 1, or 2 steps
    • Each step: up, down, left, or right
    • Cannot cross walls or pass through other stones
  3. Build a wall on any open side of your stone's current cell

Walls

  • Walls are permanent once placed
  • Walls cannot be placed on the board's outer edge : the edge already acts as a natural wall
  • You may wall in an opponent's stone; trapping is legal
  • Walls appear as coloured borders matching the player who placed them

Match end

The match ends when every empty cell on the board belongs to a player's territory: all space is claimed.

Scoring

  • Each territory cell = 1 point
  • Highest total score wins
  • If tied: player with the largest single territory wins
  • If still tied: draw

Handicap

  • A territory bonus can be given to any player to balance skill differences
  • The bonus points are added to that player's final score
  • All players still have the same stones, moves, and walls

Time limit

Configurable per match. If time runs out, a random move and wall placement are made automatically.

Bot opponent

Any player can be set to a bot in the new match dialog. The bot evaluates moves based on territory control, stone mobility, and board influence. The timer is paused during bot turns.
