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.
