How the daily works

One classical tsume a day, the same for everyone. Every move you make must be check, and the defender always plays the longest resistance. A wrong move is taken back and the reason shown — it costs nothing but a mark on your result. It never costs a life.

Your streak counts consecutive puzzle numbers solved, so time zones don't matter: you have until the rollover (midnight Japan time (15:00 UTC)). A day with no puzzle never breaks a streak. Mate lengths follow the week: 1手詰 Monday–Tuesday, 3手詰 Wednesday–Saturday, 5手詰 Sunday.
