most puzzle apps run on guilt. ninesmith runs on the opposite.
it's a calm daily sudoku with a coach — the smith — who quietly notices you. miss a day? no red screen, no lecture. he just keeps your seat warm.
DAILY PUZZLE + STREAK
• a fresh daily sudoku, one clear goal.
• your streak is there when you want it, and never punishes you when you don't.
• classic mode whenever you want, at the difficulty you pick.
A COACH WHO NOTICES, NOT NAGS
• smart hints point at the next step instead of stealing the solve.
• the pattern trainer runs 30–90 second sessions to build real technique.
• learn singles, hidden singles, and cleaner solving habits over time.
CALM BY DESIGN
• obsidian gold, night focus, and warm studio — tuned for readability and longer, quieter sessions.
• no ads in the free tier. the board stays quiet.
WEEKLY LEAGUE
• a light weekly loop for a reason to come back — no fake opponents, no pressure.
free forever: full classic play, daily puzzles, and core hints. premium unlocks deeper coaching, more themes, and richer summaries for players who want to get genuinely better, not just finish one more grid.

What's New in Ninesmith Sudoku
1.3.1
October 24, 2026
the challenges tab is now where you earn. weekly quests pay 3–4 shop pieces each — claim them with a tap, and a dot tells you when rewards are waiting. finish all three in a week for a 6-piece chest; a completed forge now pays 10, and a countdown shows when the next one lights. new: focus mode — one classic puzzle with ninesmith's own toasts and reminders held until you finish. it can't silence other apps; do not disturb is still yours to switch on. and your progress now rides along in iCloud backups, so a new phone no longer starts from zero.
