Most Sudoku apps remember the result. Orbace remembers the solve. Su-Pu (数谱) is a move-by-move record of a Sudoku solving path. It preserves how the grid developed—not only the completed puzzle—so you can replay decisions, revisit turning points and learn from the sequence. FEATURED SU-PU ON TODAY The Today tab highlights the champion of the latest eligible finalized event. Watch the winning Su-Pu, try the same puzzle yourself, or open the complete event results. REPLAY THE SOLVING PATH Move backward and forward through a recorded solve. Review placements, notes, corrections and undo actions as the grid unfolds. KEEP YOUR SU-PU Eligible personal solves are saved in Record Hall. Search your collection, review details and notes, replay past attempts, create certificates, and share eligible Su-Pu records. PLAY THE SAME PUZZLE After studying a featured solve or finalized result, play an untimed, unranked copy of that event’s puzzle. Compare your approach without affecting the official leaderboard. COMPETE IN RANKING GAMES Enter Daily Ranking Games, Weekly Cups and Grand Tournaments under shared rules. Final leaderboards connect eligible results to their available Su-Pu replays. LEARN, PRACTICE AND IMPROVE Use teaching hints, technique practice, Scholar’s Path and Journal studies to understand difficult moves instead of simply revealing an answer. PLAY YOUR WAY Enjoy the daily Tea Moment or explore Puzzle Packs across multiple difficulty levels. Casual puzzles do not require an account, and the timer is optional. KNOW HOW YOU FINISHED Completed personal puzzles produce a Scorecard with difficulty, time, mistakes, hints, steps and a transparent Puzzle Score breakdown. Personal Puzzle Score is separate from official Ranking Points. OPTIONAL COMPETITION PASS Orbace is free to play. An optional Competition Pass provides access to eligible limited-time competition events and an ad-free experience. Available purchase options may include an annual pass and one-time event access.
