Sudoku GM- Classic Sudoku Game

Sudoku GM is a classic Sudoku puzzle game you actually get better at. Most puzzle apps hand you the answer when you get stuck. Sudoku GM shows you the reasoning. Ask for a hint and it names the technique, highlights the cells that prove it, and explains the logic - then lets you place the number yourself. Play long enough and you stop needing hints at all. HOW IT WORKS A classic Sudoku puzzle is a 9x9 grid. Place the digits 1 to 9 into every cell so that each digit appears only once in each row, each column and each 3x3 box. Every board has exactly one solution. SEVEN DIFFICULTY LEVELS Beginner, Easy, Medium, Hard, Advanced, Expert and Grand Master. Every board is graded by the solving techniques it genuinely requires, so a Hard puzzle is hard for a real reason - not because clues were stripped out at random. New levels open up as you improve, so you are never dropped somewhere you are not ready for. HINTS THAT TEACH A hint engine that knows 58 techniques, from naked singles to X-Wing, Swordfish and forcing chains. Every hint comes in three steps - a nudge, the setup, then the answer - and you stop at whichever one you need. Teach Me mode walks you through a technique on a real board, one move at a time. DAILY CHALLENGE A new classic Sudoku puzzle every day, the same one for every player. Build a streak, watch it light up on the calendar, and set a goal for a bigger reward. Finish a day and open one of three gift boxes. BATTLE Head to head against another player on the same board. Same clues, same start, first to solve it wins.
