Sudoku is the classic 9×9 number puzzle where every row, column, and 3×3 box must contain the digits 1 through 9 with no repeats. Tap a number, pick an empty cell, and work your way through the grid using logic and deduction. You can also drag the number into the cell. It's one of the world's most popular brain games for good reason.
Tailored for seniors, this version of Sudoku offers large numbers, clear grid lines, and simple tap-to-place controls. Easy puzzles start with more numbers filled in, while Hard puzzles leave you with fewer clues.
