A five-in-a-row board game with an engine that explains itself: every move comes with the shape it built, the threat it answered and the alternatives it weighed. Learn from ten lessons and 1,680 proven puzzles, review your games move by move, and play ranked online or entirely offline.
An opponent that explains itself
Most engines hand you a move and leave you to guess why. GomokuZero plays, then tells you what it was thinking: what shape your last move built, what its reply took away from you, which alternatives it weighed and why it passed on them — and it defines the vocabulary as it uses it, so "open three" and "four" stop being jargon the first time you meet them.
Ask it anything at any point: suggest a move for me, why not here?, or what decided this.
Play
Against the engine — a neural network trained by self-play, at four strengths from a gentle introduction to a level that will not be flattering you.
Three rule sets — freestyle, standard, and renju with its forbidden moves for black.
Two players, one screen — with a clock if you want one.
Online — ranked games against someone near your rating, or a friendly game with a Steam friend. Ratings live on the Steam leaderboard.
Learn
Ten lessons from the rules to shapes, double threats, defending in the right order, and the renju forbidden moves.
1,680 puzzles across five difficulty levels. Every one was generated by exact search and checked by the test suite, so each has a solution that provably works — no "best guess" answers.
Review any game you have played — step through it against the network's read of each position, and stop at any move to ask the engine what it would have done instead.
Yours, offline
The course, the puzzles, the engine and two-player games need no account, no connection and no sign-in. The engine runs on your own machine — your moves are never uploaded. Your games are saved as a plain text file you can read, keep or delete. Only ranked play needs to be online, and it says so.

حداقل
- Requires a 64-bit processor and operating system
- OS: Windows 10 64-bit (version 1909 or later)
- Processor: x64 processor with SSE4.2, 2 cores, 2.0 GHz
- Memory: 2 GB RAM
- Graphics: DirectX 11 GPU with compute shader support; integrated graphics are fine
- DirectX: Version 11
- Storage: 500 MB available space
- Sound Card: Any Windows-compatible audio device
- Additional Notes: The course, the puzzles, games against the engine and two-player games run entirely offline — no account and no connection. Ranked play against other people needs an internet connection and a Steam account. A faster processor or GPU mainly raises the engine's strength ceiling at the top difficulty; the lower difficulties play well on modest hardware.
