You always play black, and white leads half the time. Either side may pass to indicate tenuki. An incorrect move or pass will fail the attempt and display correct variations. Click the board to start the next attempt!
Score points for each move in a successful joseki, with multipliers for combos, unique joseki finished, and total joseki in your library. Practice everyday to keep your streak.
Enter moves and an optional comment, then hit save. Your new joseki will appear in practice sessions, and the comment will be displayed once it is completed.
You can click existing joseki in the menu below to edit them, toggle them on/off in practice sessions, or remove them.
Joseki can be created in named groups, and each group can be toggled on/off in practice sessions. This allows you to practice just the groups you'd like to focus on.
All joseki are automatically mirrored, rotated, and played by both colors during pratice sessions - no need to manually enter these variations.
If you're like me, you can't remember a joseki the first time you learn it in a lecture or a game review. I wanted a place I could write down the joseki, fuseki, and other patterns I "should" know. Wouldn't it be great if that list also helped you practice, too?
The other tools I found for practicing joseki had pre-made libraries that were full of variations I hadn't learned, and didn't want to understand yet. So I created Joseki Cat to practice just the joseki I wanted. Hopefully it helps you too!
Remember, just memorizing joseki isn't that helpful!
I suggest entering joseki you learn (and understand!) from lectures, books, and reviews. Put useful information in the comments about when you might use the joseki.
Then, do practice sessions in Joseki Cat in order to make sure they stay fresh in your mind.
If you find that your sessions are nearly 100% correct, it's probably time to add some new joseki to your repertoire!
