Go Game: Baduk, Weiqi & Igo

Jacob Stinson

About this game

Go is the ancient board game of territory, known as Baduk (바둑) in Korea, Weiqi (围棋) in China and Igo (囲碁) in Japan, made for quick games on your phone. Place stones, surround empty space, capture your opponent's groups and win the count on a 9×9 board.

FOUR WAYS TO PLAY
• Online: get matched with players near your rating and climb from Bronze to Champion.
• Friends: challenge a friend to a friendly or ranked game, or send an invite link to someone new.
• Bots: six computer opponents that work offline. Beat one to unlock the next, with hints and undos when you need them.
• Pass & play: two players, one phone.

A PUZZLE EVERY DAY
• A new life-and-death problem every day, drawn from 422 classic corner positions.
• Some take one move, others a whole sequence. Every puzzle is checked to have exactly one right first move.
• Solve it first try for 100 XP. Stuck? A hint costs a little XP.
• Solve on the day to build a streak, and catch up on any day you missed from the puzzle calendar.
• An evening reminder if today's puzzle is still unsolved.

A BOARD THAT EXPLAINS ITSELF

• Tap the score for a full breakdown of stones, territory and komi.
• A How to play guide covers every rule with board diagrams: liberties, capture, ko, territory and how the game ends.
• 30-second turns keep online games moving.

REAL RULES, BUILT FOR MOBILE
• Area scoring: your stones plus the empty points only you surround.
• 7 points of komi for white, so a game can end in a draw.
• No suicide moves, positional superko, and two passes in a row end the game.
