TengenGoAbout TengenGo
A Go trainer that shows its work.
Play KataGo. Review a decision. Leave with one idea.
TengenGo is a public-preview Go trainer for deliberate practice. Play normal Go with Chinese area scoring, invite a friend, review a game, import a supported SGF record or solve a tsumego problem.
What you can use today
- 9 × 9, 13 × 13 and 19 × 19 boards, with configurable game settings.
- KataGo analysis and human-style opponent profiles when the required model is available.
- Move-by-move review, isolated study variations and SGF import/export.
- Board Oracle questions, group overlays and a personal practice profile.
- Experimental Fog of War and Multiverse modes, clearly separate from normal Go.
What the version numbers mean
TengenGo 1.0.0, public preview identifies the application release. The visible build fingerprint distinguishes source bundles, including builds made before changes are committed. Settings > About reports the client fingerprint and connected server build.
KataGo's version identifies the loaded AI engine. Protocol and API numbers describe software compatibility; they are not versions of the rules of Go. See Rules & modes for the actual playing rules.
A measured teaching tool
Hints and analysis are optional. Language-model explanations require your own configured provider and may send game context to that provider. Engine results and prose are kept separate. TengenGo does not promise rank gains, a certified opponent rank, unlimited search or error-free explanations.
The project and operator
TengenGo is operated by Dmitrij Sosnovic in the Czech Republic. For support, privacy requests or feedback, contact [email protected].
The name comes from tengen, the centre point of the Go board. The centre-stone mark, dark interface and blue accent express a simple aim: keep the board at the centre of your study.
