Sudoku Kensei is a powerful Sudoku game and teacher designed to help you understand and solve puzzles — not just fill in the boxes. SOLVE SMARTER WITH VISUAL FINDERS Turn on any finder and the board lights up with color-coded hints. Naked Singles, Hidden Singles, Box Exclusions, Naked Pairs, Triples, Quads, and more — each technique is highlighted so you can see the logic, not just the answer. Finders never solve for you; they show you where to look. ADVANCED FISH PATTERNS (PRO) Tackle the toughest grids with X-Wing, Swordfish, and Jellyfish finders. Each pattern is highlighted with color-coded cells and backgrounds. Select a digit on the keypad to isolate one fish at a time — perfect for studying and learning advanced technique. SCAN ANY PUZZLE Point your camera at a printed book, magazine, or on-screen puzzle, or scan from an existing photo or screen capture of a puzzle. Review recognized digits before solving, and correct any misreads with a tap. SMART CANDIDATE MANAGEMENT Show all pencil marks with one tap.
