About Medium Sudoku
This medium Sudoku mode uses a classic 9x9 grid, unique-solution puzzle generation, timer tracking, mistakes, undo, erase, pause, and limited hints.
The goal is to fill every empty square so each row, column, and 3x3 box contains the numbers 1 through 9 exactly once.
How to Play
Tap a square and choose a number, or use your keyboard. Arrow keys move the selected square, number keys enter values, and Backspace or Delete erases editable squares.
Pause hides the board until you resume. Use hints sparingly so the puzzle remains a logic exercise instead of a guessing loop.
Difficulty Path
Easy and Medium Sudoku build rule fluency. Hard, Expert, Master, and Extreme Sudoku reward cleaner notation and deeper eliminations.
Medium Sudoku sits in this path as a distinct challenge so players can bookmark the right level and return later.
