Sudoku
Focus · Logic · Journey
No ads, no timers pushing you around — just the puzzle.
What it does
A ladder, not a wall
Three board sizes — 4×4 to learn, 6×6 to build, 9×9 to master — so the same app suits a first puzzle and a thousandth.
Difficulty you can trust
Five levels from Breeze to Zenith, graded by the actual solving techniques a puzzle requires — not by how many numbers were deleted.
Hints that teach
Three assistance modes, from pure to guided. Guided mode names the technique that unlocks your next move, so hints make you better instead of dependent.
Made to be savored
Two atmospheres — Luminous, a deep violet night, and Paper & Ink, a quiet analog day — with sound, haptics, and a victory that feels like one.
Progress that means something
Daily puzzles, streaks, best times and perfect solves, tracked per board size. Saved locally; resume any time.
For every solver
Full English and Telugu localization, real contrast ratios, non-color cues for every state, and proper reduced-motion support.
