Go – The Ancient Game of Strategy

Go is one of the world’s oldest and most profound strategy board games. Played on a grid of intersecting lines (commonly 19×19, though smaller boards like 9×9 or 13×13 are also popular for beginners), two players take turns placing black and white stones on the intersections. The objective is simple yet deep: surround more territory on the board than your opponent while capturing their stones through encirclement. Despite its straightforward rules, Go offers astonishing complexity and endless room for creativity, calculation, and intuition.

In our online version you can play against a friend in local two player mode or compete against our advanced AI. Attempt to gain as much territory as possible in order to win each match.

History of Go

The origins of Go stretch back over 4,000 years in ancient China, making it the oldest board game still played in its original form today. It was considered one of the "Four Arts" of a cultured Chinese scholar, alongside calligraphy, painting, and playing the zither. Over centuries, Go spread to Korea and Japan, where it flourished and evolved into the highly codified form we recognize today. In Japan, Go became a cultural institution with professional houses and national competitions. Today, Go has a thriving international community, professional leagues, and digital platforms where millions of players worldwide continue the tradition.

Game Tips

  1. Think Globally, Not Just Locally: Unlike chess, where the battlefield is centralized, Go requires balancing small tactical fights with the larger strategic landscape.
  2. Corners → Sides → Center: Securing territory usually starts in the corners, then extends to the edges, and finally the center.
  3. Don’t Chase Every Capture: Efficiency matters. Sometimes ignoring a local skirmish to strengthen your overall position leads to victory.
  4. Balance Attack and Defense: A strong player knows when to solidify their groups and when to pressure their opponent’s weak formations.
  5. Study Pro Games: Reviewing games by masters or AI programs like AlphaGo can reveal deep insights into shape, balance, and efficiency.

Why Playing Go Benefits the Brain

Go stimulates both analytical and intuitive thinking, engaging the left and right hemispheres of the brain. Research suggests that regular play improves: Problem-Solving & Critical Thinking – evaluating multiple outcomes and long-term consequences. Memory & Pattern Recognition – identifying familiar shapes and learning efficient responses. Creativity & Imagination – finding innovative strategies and new shapes. Patience & Emotional Regulation – learning to remain calm during setbacks and play with long-term perspective. Because of its depth, Go has been studied in cognitive science as a tool for enhancing brain plasticity and decision-making.

Go is more than a board game; it is an intellectual journey, a cultural artifact, and a timeless contest of wits. With simple rules but infinite possibilities, every game of Go is unique, challenging, and rewarding. Whether you are a beginner learning the basics on a 9×9 board or an advanced player mastering the intricacies of 19×19 battles, Go offers a lifetime of discovery.

How to Play

Play on PC or mobile device. Click or touch to place your stones. Capture more territory than opponent to win the game.

  • Board Setup: A square grid (19×19 for standard play, or smaller for quick games). Players use black and white stones.
  • Placing Stones: Black goes first. Players alternate turns, placing one stone on an empty intersection.
  • Capturing Stones: Stones (or groups of stones) are captured and removed when all of their “liberties” (adjacent empty intersections) are surrounded.
  • Territory: At the end of the game, players count the number of intersections they control (empty points surrounded by their stones) plus any captured stones.
  • Victory: The player with the greater total score (territory + captures + komi adjustment for fairness when White plays second) wins.
