Dr. Sudoku is a number-placement puzzle game where the objective is to complete partially filled 9x9 grids. Players place the digits 1 through 9 so that each number appears without repetition in every row, column, and 3x3 subgrid. The central play loop is based on examining the existing clues, identifying possible placements, and gradually filling the board while following these rules.
Difficulty and daily puzzles
The game provides multiple difficulty levels, allowing beginners to start with simpler boards while experienced players can choose more demanding puzzles. Daily challenges add another set of puzzles to the routine, giving players a recurring way to apply the same Sudoku rules to fresh boards.
Puzzle tools and approach
A pencil markings feature lets players note possible digits in a cell before committing to a final placement. This supports a careful solving process: candidates can be recorded while rows, columns, and subgrids are compared, then removed as new numbers narrow the available choices. The supplied playing guidance also recommends taking a break and returning to a difficult puzzle with fresh attention.
