Sudoku

A quiet study, one puzzle at a time. Yomoe Sudoku brings the feel of pencil on paper to your phone. Every puzzle is generated on your own device and checked to have exactly one solution. No connection needed — on a plane, underground, or anywhere else, your next puzzle is already there. ■ Five ways to play - Classic: pick Easy through Expert and solve one at your own pace. - Daily Challenge: one puzzle a day, the same one for everyone in the world. Stamps fill your calendar and your streak grows. - Journey: 6 chapters of 20 levels, 120 in all — from gentle 4x4 grids up to Expert. - Speed: a timed single puzzle, plus a sprint that keeps them coming. - Zen: no timer, no mistake count. A calm, low-contrast board and nothing but thinking. ■ Help that teaches Candidate notes, row/column/box highlighting, and matching-number emphasis. When you are stuck, a hint tells you why that digit belongs there — so you learn the technique, not just the answer. Slips can be undone as many times as you like. ■ Worth coming back to Best times and three-star rates per mode and difficulty, achievements and trophies, and your daily streak. There are no leaderboards to compete on. The only one you are measured against is yesterday's you. ■ Built to be comfortable Everything within reach of one hand, a left-handed mode, and colour-blind friendly marking. 10 languages. Portrait only. ■ Pro version (one-time purchase) - No ads - Unlimited hints (free: 3 per puzzle, plus more by watching a video) - All 5 board themes unlocked (Study Paper, Night Ink, Celadon, Ochre, Bamboo Dew) The free version still gives you all five modes, all 120 levels, and every achievement and statistic, with nothing held back. Pro only buys you an uninterrupted screen and a change of scenery.
