What is Mini Go Online?

Mini Go is a simplified version of the ancient game Go, played on a 9×9 board instead of the traditional 19×19. Two players alternate placing black and white stones, aiming to control more territory than their opponent. Go teaches profound strategic thinking where global board position matters more than local tactics. Mini Go retains all of Go's elegance in a faster, more accessible format perfect for learning the game's principles without intimidating complexity.

How to Use

Launch the game and share a room code with your friend. Black plays first. On each turn, click an empty intersection to place your stone. Stones adjacent to opponent stones form groups. A group is captured when all adjacent empty spaces (called liberties) are completely filled by opponent stones. The game ends when both players pass consecutively, indicating no more profitable moves. The system then calculates territory by counting uncontested empty spaces and captured stones. The player controlling more territory wins, with komi points adjusting for Black's first-move advantage.

Use Cases

• Learning Go strategy: 9×9 is the perfect training ground for Go beginners before advancing to 19×19 competitive play.
• Quick strategic games: A 9×9 game completes in 10-20 minutes, ideal for busy players wanting strategic depth without huge time investment.
• Teaching position evaluation: Teachers use Mini Go to illustrate territorial control, influence, and life/death problems clearly and interactively.
• International competition: Mini Go has competitive communities because it's accessible globally—no language barrier, pure strategy and skill.

Tips & Insights

Strong Mini Go players balance territory claiming and fighting for influence. The opening focuses on controlling corners and edges (easier to secure with fewer stones). Mid-game emphasizes influence—limiting opponent expansion while securing your position. End-game requires careful counting: sometimes sacrificing stones to secure larger territory proves strategically sound. Understanding life and death (whether a stone group survives) is central to Go strategy.

Frequently Asked Questions

How do I play online with friends?

Click "Create Room" to generate a room code and share it with your friend. When they enter the code in "Join Room", the game starts.

How are first and second player determined?

The person who creates the room (host) plays black and goes first. The person who joins (guest) plays white and goes second.

What are the basic rules of Go?

Players alternate placing stones on intersections. When all of an opponent's stone's liberties are blocked, it's captured. The game ends when both players pass consecutively, and the winner is determined by territory size. White receives 6.5 points (komi).

Why is the board 9×9 instead of the standard 19×19?

A 9×9 board provides faster gameplay (10-25 minutes) while preserving Go's strategic depth, making it ideal for casual online matches.

How long does a typical game last?

Most games take 10-25 minutes; quick matches can finish in 5 minutes, while deeper strategic games may extend to 30+ minutes.

What is the Ko rule?

The Ko rule prevents immediate recapture of a single stone—if your opponent captures your stone, you cannot immediately recapture theirs in your very next turn.

How is the final score calculated?

The score combines your captured opponent stones plus the empty territory you control on the board; the player with the higher total wins.

Can I pass or resign during a game?

Yes, you can pass your turn if you see no beneficial moves, and you can resign at any time to concede the game to your opponent.

Can experienced players use handicaps for beginners?

This version does not support handicap stones; all games start with an empty board, requiring both players to play under identical conditions.
