One puzzle, one tea, one quiet moment.
Orbace Sudoku is a calm, teaching-first Sudoku app. No timers screaming at you, no clutter fighting for your attention — just a well-made grid, room to think, and puzzles that respect your time.
TEA MOMENT
Open one featured daily puzzle as a deliberate pause in your day. A new Tea Moment puzzle arrives every day, from gentle warm-ups to genuinely hard challenges.
LEARN AS YOU SOLVE
Teaching hints guide every step instead of just handing you the answer. Work through a technique playbook and practice packs that build real solving skill, puzzle by puzzle — not just luck.
SU-PU 数谱 — REPLAY YOUR SOLVES
Every solve can be preserved as a Su-Pu: a move-by-move record of how you actually got there. Revisit your own path, see where you hesitated or found the key insight, and share a replay with a link.
TRACK YOUR PROGRESS
Scholar's Path awards recognize real, growing understanding — not just streaks. Watch your solving history and achievements build over time.
COMPETE GLOBALLY
Jump into Ranking Games and see how you stack up on the global leaderboard. Start ranking instantly — no account required to get going. Sign in with Google, Apple, or email to save your progress across devices, appear on the leaderboard, and unlock the full Global Ranking and results history.
COMPETITION PASS (OPTIONAL)
