WHY PLAY SUDOKAI? ◆ INTELLIGENT 3-STEP AI TUTOR Most Sudoku apps just fill in the number for you when you get stuck. SudokAI teaches you HOW to solve it: 1. Focus: Highlights the exact row, column, or 3x3 box where progress can be made. 2. Technique: Identifies the logical method to use (e.g. Naked Single, Hidden Pair, X-Wing). 3. Solution: Reveals the underlying deduction and the number when you're ready. ◆ SCAN PAPER SUDOKUS WITH YOUR CAMERA Spotted a great puzzle in a newspaper, magazine, or book?
