Weekend Sudoku 18

Weekend Sudoku 18 is a classic number puzzle where the answer is built inside a 9x9 grid. To complete it, each row, column, and 3x3 section must contain the digits 1 through 9 without repetition. The enjoyment comes from using those overlapping rules to turn incomplete information into definite placements.

The board is controlled with the mouse, keeping the interaction simple while the reasoning provides the challenge. As more cells are solved, the remaining choices become narrower. Careful checking matters because a number that looks suitable in one direction may break the rule in its column or smaller section.

Use the mouse to select and interact with the grid.

Fill the empty cells with digits from 1 through 9.

Check each number against its row, column, and 3x3 section.

Continue making valid placements until the entire Sudoku grid is solved.
