About Sudoku
Modern Sudoku was designed by Howard Garns in 1979 and first published as "Number Place" in Dell Puzzle Magazines. Japanese publisher Nikoli popularized it globally in 1986 under the name Sudoku, meaning "single digit." Today an estimated 100 million Sudoku puzzles are solved every day by enthusiasts around the world.
How to Play
- Start with a 9×9 grid partially filled with digits (the "clues").
- Fill every empty cell so each row, column, and 3×3 box contains the digits 1 through 9 exactly once.
- Use only logical deduction — no guessing is needed in any well-formed puzzle.
- Complete the entire grid correctly to solve the puzzle.
Tips & Tricks
- Scan first: Start by scanning rows and columns for digits that can logically go in only one cell.
- Use pencil marks: Enable candidate notes to track possible digits in ambiguous cells before committing to a number.
Frequently Asked Questions
Do I need to be good at math?
No math at all! Sudoku is purely a logic puzzle. The digits 1–9 are arbitrary symbols — what matters is pattern recognition, not arithmetic.
How many difficulty levels are available?
We offer multiple difficulty settings, from Easy (few empty cells, straightforward logic) to Expert (complex deduction chains requiring advanced techniques).
Are the puzzles unique and solvable?
Yes. Every puzzle in our Sudoku is generated with a single, verified solution — no ambiguity or guessing required to finish it.
