Sudoku – One of Each

Rows, columns, boxes — pure logic. No lives, no gimmicks, no account. Sudoku – One of Each is the classic puzzle, built to be played every day. Start gently on a 4×4, meet the third rule on the compact 6×6, and work up to the full 9×9 grid. A 60-LEVEL JOURNEY Five chapters, from First Steps to Grandmaster, hand-tuned so the difficulty climbs with you. Solve with no hints and no mistakes for all three stars, earn XP, and rise from Novice to Grandmaster. A NEW PUZZLE EVERY DAY One daily puzzle, the same one for every player, with a calendar of every day you have solved. Keep the streak alive — and when life gets in the way, a freeze covers one missed day. You earn another every 7 days in a row. QUICK PLAY, WITHOUT END 4×4, 6×6 or 9×9, from Easy to Expert, generated fresh every time and always with exactly one solution. ZEN The same puzzles with no clock and no mistake counter. Flip the switch on the home screen when you would rather think than race. HINTS THAT TEACH A hint does not just fill a cell. It points at the one cell you can solve now and names the reason — a naked single, a hidden single, a pointing pair, a box/line reduction — so you learn the technique instead of borrowing an answer. EVERYTHING ELSE • Pencil marks, undo, and conflict highlighting — each of them optional • Number-first or cell-first input, whichever way you scan a grid • Stats: solved, perfect solves, stars, time played, best times • A home-screen widget with today's puzzle and your streak • Share a finished solve, or send a friend the exact puzzle you just beat • An optional reminder at 7 PM, if today's puzzle is still waiting • English and Italian Free, with ads. One purchase removes every ad for good — and makes every hint free, with no video to watch first.
