Sudoku Master Daily Puzzle

■ What makes this different? Most sudoku apps just reveal the answer when you tap Hint. Sudoku Master explains WHY that number belongs there. "R3C4 can only be 9 — its row, column and box already rule out every other candidate." A solver that knows 12 human techniques reasons the way a person does, and shows you the path to the next move. You don't copy answers; you actually get better. ■ Technique practice Heard of Naked Pair, X-Wing or Swordfish but never used them? Practice mode serves you puzzles that genuinely require a chosen technique, and the hint walks you through the logic when you get stuck. Grow step by step, from beginner to expert. ■ 9 difficulty levels Mini (4x4), then Beginner, Easy, Medium, Hard, Expert, Master, Extreme and Evil.
