neun. Sudoku – Logic Puzzle

neun. is Sudoku without distractions. No ads, no account, no tracking – just the grid, your numbers and exactly the help you need. FOUR DIFFICULTY LEVELS From Easy to Expert. Every puzzle is checked before it starts and has exactly one solution. HINTS THAT EXPLAIN A hint doesn't just give away the answer. First it shows you where a number can be placed for certain. Tap again and it explains why, right at that cell. So you learn the techniques instead of just finishing the puzzle. QUICK NOTES Press and hold a number to add a note. Or fill in every possible candidate with a single tap. Undo and erase are always at hand. A NEW PUZZLE EVERY DAY The daily puzzle is the same for everyone. Solve it every day to build your streak – and if you miss a day, your grace day has your back. HONEST STATS Played, solved, best time and daily streak. Using hints still solves the puzzle – it just doesn't count as a best time.
