About Go
Go is played here on a compact 9x9 board, ideal for quick games. You are Black and move first. Surround empty points and capture enemy groups; when neither side can improve, both pass and the area is counted with 5.5 komi for White.
Tips and strategy
- Start near the star points (the dots) and build shapes with room to make two eyes.
- A group with two separate eyes cannot be captured, so aim to make them.
- Keep your stones connected; cutting points are where games are won and lost.
- Before passing, capture any enemy stones that cannot live — area scoring counts them as alive.
- You cannot play a move that repeats an earlier board position (the ko/superko rule).
What it exercises
Go builds spatial reasoning, long-range planning and pattern recognition. Short 9x9 games let you practice the same ideas as the full board in a few minutes.
Frequently asked questions
- How is the winner decided?
- When both players pass in a row, each side scores its stones plus the empty regions only it surrounds. White adds 5.5 komi to offset moving second.
- Can I play a friend?
- Yes. Press Play a friend, send the invite link and a chat opens for the two of you. You play Black and move first; your friend plays White. Friend games do not post to the leaderboard.
- Is there a leaderboard?
- Yes, wins against the computer post a score by difficulty and winning margin to the Top 5.

Measure an exact volume of water using three jugs of different capacities. A classic water-jug riddle — with only fill, empty and pour moves allowed, the goal is finding the exact sequence that leaves the target amount in a single jug.
