Sudoku Puzzle
About Sudoku Puzzle
Nine rows, nine columns, nine boxes, and each one has to hold every digit from one to nine exactly once — the rules take a sentence, and the difficulty comes entirely from how few numbers you are given to start with. Scanning beats guessing: pick a digit, run it through every box in turn, and place it wherever only one square is still open to it. Pencil marks matter more as the grids harden, because the later placements come out of pairs and triples eliminating candidates rather than out of anything visible at a glance.
How to Play
- Click a square, then choose the digit that belongs in it.
- Scan one digit at a time across all nine boxes.
- Note candidates in any square where more than one digit fits.
- Use pairs — two squares that can only take the same two digits — to rule others out.
Sudoku Puzzle FAQ
Is guessing ever necessary?
Not on a properly built grid. Every placement follows from what is already on the board, so a square that seems to demand a guess usually means a candidate was eliminated too early somewhere else.
