Overview

• ONE is a simple strategy game for 2-6 players.
• Your goal is to form the ONE largest group of connected stones.
• Capture opponents' stones to block their expansion and add points to your score.
• At the end of the game, the player with the highest score wins.

Game play

• Players take turns to either:
  1. Place a stone, or
  2. Capture a stone

Place a stone

• A stone of the player's colour may be placed on any empty intersection on the board.
• Stones are connected if they are on adjacent intersections with a line between them.
  • Stones placed diagonally are not connected.
• Here are some examples of connected stones:

Captures

• Instead of placing a stone, a player may choose to capture one of their opponent's stones.
• Captured stones count for two points.
• A player may only capture an opponent's stone if:
  • Their stone is adjacent to the stone being captured, and
  • There is an empty intersection directly on the opposite side of the opponent's stone.
• Multiple captures are permitted, even if they are of multiple colours.
  • You may not capture diagonally, or capture your own stones.
• Here are some examples of legal captures:

Captures on BGA

• To make a capture:
  1. Select your stone
  2. Select the empty intersection opposite your opponent's stone.
• With the Training Labels option enabled, stones with captures available will be marked with an A.

Game End

• When a player runs out of stones, the game ends just before the turn of the starting player.

Scoring

• Player score = [# of stones in the largest connected group] + 2 × [# of captured stones]
• The player with the highest score wins.
