Use it when
You want a quiet desktop board for a quick game, a harder AI match, or a visual post-game review that shows where the position turned.
Goban · Desktop Gomoku game
A focused Gomoku board for desktop
Play on a clean 15×15 board, challenge four AI levels, then review the full game through an evaluation curve and a list of decisive mistakes.
A look inside
Play, inspect, and return to any move
The board keeps the current game, AI controls, move list, appearance, and SGF tools together in one desktop app.
Move-by-move review
Return to the move that changed the game
Enable replay analysis and select any move from the record. The board reconstructs that position and explains decisive mistakes beside it.
Notebook theme
A board that feels drawn into your notes
Switch from traditional stones to triangle and circle marks on ruled paper. The game state, winning line, and controls remain the same.
Fit and limits
Fit and limits
Current platforms
Desktop releases for macOS and Windows; no online matchmaking.
Local by design
Gameplay, saves, analysis, and imported records run locally with no account required. Goban is a desktop board, not an online game service.

Four AI levels
Choose easy, normal, hard, or extreme, then set your color and a fast, standard, or deep thinking budget.
Hints you control
Press H to reveal a suggested intersection. The hint never places the stone for you and remains available during review.
Replay 2.0
Open a full-game evaluation curve and a blunder list after a match. Select a point or mistake to jump directly to that move on the board.
Named save slots
Keep up to 30 named local saves, then resume the position you want instead of overwriting one global checkpoint.
SGF review and continuation
Copy, export, import, paste, or drag in an SGF record; jump to any move and continue an unfinished game when you choose.
Board controls that stay close
Toggle the sidebar and coordinates, undo or start over from the keyboard, and keep the move list and analysis within reach.
FAQ
Which systems are supported?
The current release provides an Apple Silicon arm64 build for macOS and an x64 build for Windows. An Intel Mac build is not published.
Does it need an account or internet connection?
No account is required. Gameplay, saves, analysis, and SGF work stay local; you only need the internet to download a release.
Can I bring in an existing game?
Yes. Import, paste, or drag in an SGF file, review the move list, and continue if the position is not finished.
