What makes a Sudoku hard?
The rules stay the same at every difficulty. Apple Support describes Sudoku as a 9×9 grid made of nine blocks, with each digit appearing exactly once in every row, column, and block. As Apple puts it, “In sudoku puzzles, you place the numbers 1 to 9 into squares in a grid consisting of nine blocks with nine squares each, so that every number appears exactly once in each block, row, and column.”

Apple describes challenging puzzles as requiring more complex strategies to narrow down the possibilities for empty squares. That is a useful way to think about a hard grid: fewer placements are immediately obvious, so you keep track of candidates and use relationships among rows, columns, and blocks.

How to solve a hard Sudoku without guessing
- Scan for missing digits. Check each row, column, and 3×3 block. Note which numbers are absent and whether any empty cell has only one possible choice.
- Record candidates. When a cell is not immediately clear, list the digits that could fit without repeating a number already in its row, column, or block.
- Look for a digit with few possible positions. Within a row, column, or block, compare the candidates. If a missing digit can go in only one cell in that unit, place it there.
- Update after each confirmed placement. Remove the placed digit from candidates in the same row, column, and block, then scan those units again. A new placement can make another cell or digit position clear.
- When progress stalls, revisit the relationships. Recheck candidate lists against every affected row, column, and block. Keep deductions tied to what the grid proves; do not treat a guess as a rule or assume a particular technique is needed for the dated puzzle.
