Charles O. — Sudoku player for 22 yearsThey generate puzzles that require guessing, mislabel difficulty, or bury you in ads. Final Sudoku is different. Every puzzle is mathematically verified. Every difficulty level is honest. And you'll never see an ad.
Found a puzzle in the newspaper? A friend shared one? This is what sets Final Sudoku apart.
No guessing. No trial and error. Every puzzle has exactly one solution, solvable through logic alone with technique-verified difficulty ratings.
Five true levels from Easy to Extreme, each requiring specific solving techniques. When we say Hard, we mean it. No fake "Expert" puzzles that are actually easy.
Play with Numbers (1-9), Letters (A-I), Colors, or Greek letters. Same puzzles, fresh perspectives so you're always challenged.
Hints explain the logic behind each step, helping you learn real solving techniques. They give you the answer only when you ask for it — not before.
Single press Notes button or long press for automatic Notes. Auto-fill candidates at any stage of the puzzle. Auto-candidate cleanup when you place a number.
Check your answers against the solution at any stage. Optionally remove wrong numbers automatically. Highlight mistakes, singles, and same numbers as you play.
Timer, mistake highlighting, single highlighting, same-number highlighting, auto-candidate cleanup, adjustable font size, and single-handed play on mobile.
Print your puzzle at any stage — from the very beginning or even partially filled in. Take your Sudoku offline on paper whenever you want.
Total completed puzzles, best streak, average and best times per difficulty, progress charts over weeks and months. Start fresh anytime by deleting all stats.
Clean, distraction-free interface. Light, Dark, and OLED display modes. Works completely offline. Zero ads, zero tracking, forever. Just you and the puzzle.
