📚 Features

🎯 Full Study

A book-style diagram of the game and a replay board: guess each move on the diagram; hints narrow the region after a wrong try.

🤔 Guess the Next Move

Play the game as Black, White or both: the opponent's moves come by themselves.

📝 Sequential Memorization

Memorize a part of the game (5 to 30 moves), then place it on the board from memory.

🔄 Spaced Repetition and Repeat my mistakes

Series of games repeated with fewer hints each time; and the single moves you missed, back on their days until they are learnt.

🗄️ Games

The bundled games, your own SGF files and the games of the study.baduk.org server with its collections. A server game you study is kept on your computer.

Every session and move: first-try guesses, wrong clicks, time, by mode and period.
