Update 01.02.2024
Explanation for the duplicate update on 01.02.2024
We decided to merge the duplicate problems on the website. This means, that when you solve a problem and it has duplicates, it is also solved in other collections. When you had a collection complete and there were unsolved problems again on 1. February, it means that duplicates were merged and you need to solve it again for all occurences of that board position.

Update 20.07.2023
New board viewer: BesoGo
We changed the technology that is used to display the problems from jGoBoard to BesoGo. There are various advantages, such as a tree display in the review, changing views without refresh, editing and saving problems on the website and more. It also opens possibilities to merge recurring board positions and to make a better result distinction. Instead of correct and incorrect, a future update is going to include more details.
It comes with a separate editor which was the starting point to make this possible. Editor

New Collection: Kano Yoshinori | 31.12.2023
This series written by Kano Yoshinori in 1985 covers a large range of fundamental topics.
Volume 1 contains problems about recognizing atari, ladders, snapbacks and basic life and death problems. Created for Tsumego Hero by Stepan Trubitsin.
New Collection: 9x9 Endgame Problems
There's a saying in Go that your overall strength is limited by your endgame strength. Even if you are leading a lot in the opening and middle game, mistakes in endgame can still lose you the game. This collection allows you to practice and level-up your endgame in a small 9x9 board with real-game examples.
New Collection: Sacrifical Tsumego
Sometimes sacrifices are necessary in order to kill, but how many stones can you sacrifice before killing?
That's the question this collection aims to answer.
New Collection: Yi Kuo
Yi Kuo is a classical kifu and tsumego book written by Huang Longshi (1651-1700). It was posthumously published in 1710.
Go Seigen once commented that Longshi's fighting skill
was of 13-dan strength. The problems in this collection are focused mainly on endgame tesujis.
