《Professional shogi player Satoshi Yanagisawa's go class collaboration announcement! 》
Thanks to Mr. Satoshi Yanagisawa, a professional shogi player belonging to Nihon Ki-in, you can enjoy the problem of "Go Video Senbon Knock" published on Mr. Yanagisawa's YouTube channel "Professional Go Player Satoshi Yanagisawa's Go Class" in the app. You can now have it.
A wide range of practical problems are included, not limited to Tsumego and Tesuji problems, so please try it!


"Go Note" is a free application that allows you to freely register Go problems and joseki, and manage and record board and game records.

It was developed by a beginner Go developer who felt the limitations of learning Tsumego and Tesuji only from the game record, in order to promote the efficient learning of Go.

It can be used as a problem book for Tsumego, or as a record of joseki procedures including chess records and variations, and can be used according to one's level, from beginners to advanced players.

・Supports sizes from 4x4 Go puzzles to 19x19 Go games
