Sudoku 2 Levels of Difficulty

A full 9x9 number grid fills the screen in Sudoku 2 Levels of Difficulty. This Sudoku puzzle suits players who already know the standard rules and want a board with either a normal setup or a hard one. Both options use 81 cells split into rows, columns, and nine small 3x3 boxes. Normal mode places more digits on the board. Hard mode begins with no more than four numbers inside each 3x3 box. Fewer givens leave more possible placements, making the final arrangement harder to pin down. The clock tracks how long the solve takes, and that time stands as your record.

How to play?

Fill the empty cells with digits that fit the standard Sudoku rule set. Work from the 3x3 box that already has the most numbers in place. Check the matching row and column before placing a digit in an empty square. A stuck position calls for eliminating conflicting options from the same row, the same column, or the current box. Move to another box after one section is filled out enough to reveal fresh placements. Correct wrong entries and test a different arrangement until the grid is complete in either difficulty.
